<p>Please read this manual before asking for help, you also REALLY want to take a look at the

|
|
<a href="http://www.vulnscan.org/UnrealIRCd/faq/" target="_blank">FAQ</a> since over 80% of your questions/problems are answered in it. If you still
|
||
|
|
need help you can ask for support at irc.unrealircd.org (port 6667) channel #unreal-support (note
|

that we REQUIRE you to read the docs and faq and we only help with UnrealIRCd, not with services!).

<p>In case you are upgrading from Unreal3.1.x to Unreal3.2 you'll notice the whole config file has changed,
|
||
|
|
you may find it hard at first, but once you've switched you'll find it much better!</p>
|
||
|
|
<p>Also don't forget to read section 3 about features, although you know already some of them which are in 3.1.x there are several new features too!</p>
|
||
|
|
<p>It's best not to mix/link 3.1.x with 3.2, but if you really want to, you need at least 3.1.4, but 3.1.5.1 is strongly recommended.</p></div>

<p>The recommended way to upgrade is:<br>
|
||
|
|
Linux:<br>
|
||
|
|
<ul>
|
||
|
|
<li>Rename your old UnrealIRCd directory (or otherwise you'll overwrite it in the next step)
|
||
|
|
<li>Extract the new UnrealIRCd version and run ./Config and make
|
||
|
|
<li>Copy your old configuration files to the new directory (unrealircd.conf, motd, rules, server.* [SSL certs], network file, etc)</p></ul>
|
||
|
|
Windows:<br>
|
||
|
|
<ul>
|
||
|
|
<li>Copy all of your configuration files to a temporary location.
|
||
|
|
<li>Run the uninstaller for any previous versions of Unreal you have installed.
|
||
|
|
<li>Run the installer for the new version of Unreal.
|
||
|
|
<li>Copy your old configuration files to the new folder.
|
||
|
|
</ul>
|
||
|
|
<p>Please also check .RELEASE.NOTES to see what has been changed.
|
||
|

<p>Some major/nice features are explained in this section. It provides a general overview,

and sometimes refers to the config file (something which you might know nothing about yet).</p>
|
||
|

<p>You can skip this section, however it's very much suggested to read it before/after installing

because otherwise you will not understand concepts such as 'cloaking', 'snomasks', etc.</p></div>

|
||
|
|
<p>Cloaking is a way to hide the real hostname of users, for example if your real host is <i>d5142341.cable.wanadoo.nl</i>,
|
||
|
|
it will be shown (in join, part, whois, etc) as <i>rox-2DCA3201.cable.wanadoo.nl</i>.
|
||
|
|
This feature is useful to prevent users flooding each other since they can't see the real host/IP.</p>
|
||
|
|
<p>This is controlled by usermode +x (like: /mode yournick +x), admins can also force +x to be enabled
|
||
|
|
by default, or make it so users can never do -x.</p>
|
||
|
|
<p>A cloaked host is generated by a cloaking module (you are required to have one loaded), currently there's only 1 module included:<br>
|
||
|
|
<b>cloak:</b> This is the official cloaking module since 3.2.1, it is much more secure than the old
|
||
|
|
algorithm, it uses md5 internally and requires you to have 3 set::cloak-keys:: consisting of mixed lowercase (a-z),
|
||
|
|
uppercase (A-Z) and digit (0-9) charachters [eg: "AopAS6WQH2Os6hfosh4SFJHs"]. See example.conf for an example.<br>
|
||
|
|
<p>Cloak keys MUST be the same on ALL SERVERS in a network. Also cloak keys should be kept SECRET
|
||

|
<p>UnrealIRCd supports modules which is nice because:<br>
|
||
|
|
- You can load/reload/unload them while the ircd is running (by /rehash). This allows some bugs to be fixed or new features to be added without requiring a restart!<br>
|
||
|
|
- Other people can create (3rd party) modules with new commands, usermodes and even channelmodes.<br>
|
||
|
|
UnrealIRCd only comes with a few modules. Take a look at www.unrealircd.com -> modules
|
||
|
|
or use google to find 3rd party modules.<br>
|
||
|
|
<p>You need to load at least 2 modules or else you won't be able to boot!:<br>
|

|
|
- the commands module: commands.so (commands.dll on windows)<br>
|

|
||
|
|
<p>SSL stands for Secure Socket Layer, with SSL you can make secure encrypted connections.
|
||
|
|
It can be used to encrypt server<->server traffic, but client<->server traffic can also be encrypted.
|
||
|
|
You usually use SSL to protect against sniffing and for authentication.</p>
|
||
|
|
<p>You need to have your IRC server compiled with SSL support. To setup an SSL port you need to set listen::options::ssl.</p>
|
||
|
|
<p>You cannot connect normally to a SSL port (so don't make port 6667 ssl!), you need a client or a tunnel
|
||
|
|
that understands the SSL protocol.</p>
|
||
|
|
<p>Clients that support SSL: <A HREF="http://www.xchat.org/" TARGET="_blank">XChat</a>,
|
||
|
|
<A HREF="http://www.irssi.org/" TARGET="_blank">irssi</a>,
|
||
|
|
<A HREF="http://www.mirc.com/" TARGET="_blank">mIRC</a> (6.14 and up,
|
||
|
|
also requires some <a href="http://www.mirc.co.uk/ssl.html" target="_blank">additional steps</a>)</p>
|
||
|
|
<p>For clients which do not support SSL you can use a tunnel like
|
||
|
|
<A HREF="http://www.stunnel.org/" TARGET="_blank">stunnel</A>, here's a stunnel.conf example (for stunnel 4.x):<br>
|
||
|
|
<pre>
|
||
|
|
client = yes
|
||
|
|
[irc]
|
||
|
|
accept = 127.0.0.1:6667
|
||
|
|
connect = irc.myserv.com:6697
|
||
|
|
</pre>
|
||
|
|
If you then connect to 127.0.0.1 port 6667, your traffic will be encrypted and forwarded to irc.myserv.com
|
||
|
|
port 6697 (an SSL port).</p>
|
||
|
|
<p>You should also validate certificates when you connect to servers and not blindly accept them (like in the stunnel example)
|
||
|
|
else you are still vulnerable to "active sniffing" attacks (ssl redirects), that's however too offtopic
|
||
|
|
to explain here (learn about SSL, don't ask us). [mIRC and xchat pop up a window asking you to allow/reject a certificate,
|
||
|

so that's good].</p></div>

<b>Throttling</b><br>
|
||
|
|
Throttling is a method that allows you to limit how fast a user can disconnect and then reconnect to your server.
|
||
|
|
You can config it in your set::throttle block to allow X connections in YY seconds from the same IP.<br>
|

|
|
<b>Channel modes</b><br>
|

There are also some channel modes which can be very effective against floods. To name a few:<br>
|
||
|
|
<b>K</b> = no /knock, <b>N</b> = no nickchanges, <b>C</b> = no CTCPs, <b>M</b> = only registered users can talk, <b>j</b> = join throttling (per-user basis)<br>
|
||
|
|
As of beta18 there's also a much more advanced channelmode +f...<br>
|
||
|
|
<b>Channel mode f</b><br>
|
||
|
|
Instead of using scripts and bots to protect against channel floods it is now build into the ircd.<br>
|
||
|
|
An example +f mode is: <i>*** Blah sets mode: +f [10j]:15</i><br>
|
||
|
|
This means 10 joins per 15 seconds are allowed in the channel, if the limit is hit, the channel will be set +i automatically.<br>

|
||
|
|
|
||
|
|
In fact, it can get even more advanced/complicated:<br>
|
||
|
|
Instead of the default action, you can for some floodtypes specify another one, for example: <i>+f [20j#R,50m#M]:15</i><br>
|
||
|
|
This will set the channel +R if the joinlimit is reached (>20 joins in 15 seconds),
|
||
|
|
and will set the channel +M if the msg limit is reached (>50 messages in 15 seconds).<br>
|
||
|
|
<br>
|
||
|
|
There's also a "remove mode after X minutes" feature: <i>+f [20j#R5]:15</i> will set the channel +R if the
|
||
|
|
limit is reached and will set -R after 5 minutes.<br>
|
||
|
|
A server can have a default unsettime (set::modef-default-unsettime), so if you type <i>+f [20j]:15</i> it could get
|
||
|
|
transformed into <i>+f [20j#i10]:15</i>, it's just a default, you can still set [20j#i2]:15 or something like that,
|
||
|
|
and you can also disable the remove-chanmode completely by doing a +f [20j#i0]:15 (an explicit 0).<br>
|
||
|
|
<br>
|
||
|
|
The old +f mode (msgflood per-user) is also still available as 't', +f 10:6 is now called +f [10t]:6 and
|
||
|
|
+f *20:10 is now +f [20t#b]:10. Currently the ircd will automatically convert old +f mode types to new ones.
|
||
|
|
Note that there's no unsettime feature available for 't' bans ([20t#b30]:15 does not work).<br>
|
||
|
|
<br>
|
||
|
|
What the best +f mode is heavily depends on the channel... how many users does it have? do you have a game that makes users
|
||
|
|
msg a lot (eg: trivia) or do users often use popups? is it some kind of mainchannel or in auto-join? etc..<br>
|
||
|
|
There's no perfect channelmode +f that is good for all channels, but to get you started have a look at the next example and modify
|
||
|
|
it to suit your needs:<br>
|
||
|
|
+f [30j#i10,40m#m10,7c#C15,10n#N15,30k#K10]:15<br>
|
||
|
|
30 joins per 15 seconds, if limit is reached set channel +i for 10 minutes<br>
|
||
|
|
40 messages per 15 seconds, if limit is reached set channel +m for 10 minutes<br>
|
||
|
|
7 ctcps per 15 seconds, if limit is reached set channel +C for 15 minutes<br>
|
||
|
|
10 nickchanges per 15 seconds, if limit is reached set channel +N for 15 minutes<br>
|
||
|
|
30 knocks per 15 seconds, if limit is reached set channel +K for 10 minutes<br>
|
||
|
|
|
||
|
|
If it's some kind of large user channel (>75 users?) you will want to increase the join sensitivity (to eg: 50) and the
|
||
|
|
message limit as well (to eg: 60 or 75).<br>
|
||
|
|
Especially the remove-mode times are a matter of taste.. you should think like.. what if no op is available to handle
|
||
|
|
the situation, do I want to have the channel locked for like 15 minutes (=not nice for users) or 5 minutes (=likely the flooders
|
||
|
|
will just wait 5m and flood again). It also depends on the floodtype, users unable to join (+i) or speak (+m) is worse than
|
||
|
|
having them unable to change their nick (+N) or send ctcps to the channel (+C) so you might want to use different removal times.
|
||
|
|
<br>
|
||
|
|
<b>Channel mode j</b><br>
|
||
|
|
The +f mode includes a feature to prevent join floods, however this feature is "global." For
|
||
|
|
example, if it is set to 5:10 and 5 <u>different</u> users join in 10 seconds, the flood
|
||
|
|
protection is triggered. Channel mode +j is different. This mode works on a per-user basis.
|
||
|
|
Rather than protecting against join floods, it is designed to protect against join-part floods
|
||
|
|
(revolving door floods). The mode takes a parameter of the form X:Y where X is the number of
|
||
|
|
joins and Y is the number of seconds. If a user exceeds this limit, he/she will be prevented
|
||
|
|
from joining the channel.

UnrealIRCd supports the basic bantypes like <i>+b nick!user@host</i>.<br>
|

|
|
Also, if a masked host of someone is 'rox-ACB17294.isp.com' and you place a ban *!*@rox-ACB17294.isp.com,
|
||
|
|
then if the user sets himself -x (and his hosts becomes for example 'dial-123.isp.com) then the ban
|
||
|
|
will still match. Bans are always checked against real hosts AND masked hosts.<br>
|
||
|
|
IP bans are also available (eg: *!*@128.*) and are also always checked.<br>
|
||
|
|
<br>
|
||
|
|
Bans on cloaked IPs require some explanation:<br>
|
||
|
|
If a user has the IP 1.2.3.4 his cloaked host could be 341C6CEC.8FC6128B.303AEBC6.IP.<br>
|
||
|
|
If you ban *!*@341C6CEC.8FC6128B.303AEBC6.IP you would ban *!*@1.2.3.4 (obvious...)<br>
|
||
|
|
If you ban *!*@*.8FC6128B.303AEBC6.IP you ban *!*@1.2.3.*<br>
|
||
|
|
If you ban *!*@*.303AEBC6.IP you ban *!*@1.2.*<br>
|
||
|
|
This information might be helpful to you when deciding how broad a ban should be.<br>
|
||
|
|
<br>
|

<b>Extended bantypes</b><br>

A prefix can also be specified (+/%/@/&/~) which means that it will only match if the user has
|
||
|
|
that rights or higher on the specified channel.

|
||
|
|
<i>Ex: ~r:*Stupid_bot_script*</i><br>
|
||
|

NOTE: an underscore ('_') matches both a space (' ') and an underscore ('_'), so this ban would match
|
||
|
|
'Stupid bot script v1.4'.</td></tr>

Here's an example: <i>/spamfilter add pc gline - - Come watch me on my webcam</i><br>
|
||
|
|
If the text <i>come watch me on my webcam</i> is found in either a private msg or a channel msg
|
||
|
|
then the message will be blocked and a gline will be added immediately.<br>
|
||
|
|
Another example: <i>/spamfilter add pc block - - come to irc\..+\..+</i><br>
|
||
|
|
This is a regex that will match on <i>Hi, come to irc.blah.net</i> etc....<br>
|
||
|
|
And an example with specified time/reason:<br>
|
||
|
|
<i>/spamfilter add p gline 3h Please_go_to_www.viruscan.xx/nicepage/virus=blah Come watch me on my webcam</i><br>
|
||
|
|
If <i>come watch me on my webcam</i> is found in a private msg then the user is glined for 3 hours
|
||
|
|
with the reason <i>Please go to www.viruscan.xx/nicepage/virus=blah</i>.<br>
|
||
|
|
<br>
|
||
|
|
Spamfilters added with /spamfilter are network-wide. They work regardless of whether the user/channel
|
||
|
|
has mode +G set, only opers and ulines (services) are exempted from filtering.
|
||
|
|
</p>
|

<p>You can also add spamfilters in the config file but these will be local spamfilters (not

A spamfilter regex can slow down the IRCd considerably. This really depends
|
||
|
|
on the regex you use (and how the regex engine handles it), some are very
|
||
|
|
fast and UnrealIRCd can execute thousands of them per second. Others can be
|
||
|
|
extremely slow, take several seconds to execute, and could freeze the IRCd.<br>
|
||
|
|
To help against this, Unreal comes with Slow Spamfilter Detection: For each
|
||
|
|
spamfilter, Unreal checks, each time it executes, how long it takes to
|
||
|
|
execute. Once a certain threshold is reached the IRCd will warn or even remove
|
||
|
|
the spamfilter.<br>
|
||
|
|
Warning is configured through <b>set::spamfilter::slowdetect-warn</b> (default: 250ms)
|
||
|
|
and automatic deletion is configured by <b>set::spamfilter::slowdetect-fatal</b> (default: 500ms).
|
||
|
|
You can set both settings to 0 (zero) to disable slow spamfilter detection.<br>
|
||

<p>UnrealIRCd now has support for CIDR (Classless Interdomain Routing). CIDR allows you to ban
|
||
|
|
IP ranges. IPs are allocated to ISPs using CIDR, therefore, being able to set a CIDR based ban
|
||
|
|
allows you to easily ban an ISP. Unreal supports CIDR for both IPv4 and IPv6. CIDR masks may be
|
||
|
|
used in the allow::ip, oper::from::userhost, ban user::mask, ban ip::mask, except ban::mask,
|
||
|
|
except throttle::mask, and except tkl::mask (for gzline, gline, and shun). Additionally, CIDR
|
||
|
|
can be used in /kline, /gline, /zline, /gzline, and /shun. Unreal uses the standard syntax of
|
||
|
|
IP/bits, e.g., 127.0.0.0/8 (matches 127.0.0.0 - 127.255.255.255), and fe80:0:0:123::/64

<p>NOTE 1: Please note that some combinations can cause problems.
|
||
|
|
For example, combining latin* and chinese-* can not be properly handled by
|
||
|
|
the IRCd and Unreal will print an error.
|
||
|
|
Mixing of other charsets might cause display problems, so Unreal will print out
|
||
|
|
a warning if you try to mix latin1/latin2/greek/other incompatible groups.</p>
|
||
|
|
<p>NOTE 2: Casemapping (if a certain lowercase character belongs to an upper one) is done according to
|
||
|
|
US-ASCII, this means that o" and O" are not recognized as 'the same character' and hence someone can
|
||
|
|
have a nick with B"ar and someone else BA"r at the same time. This is a limitation of the current system
|
||
|
|
and IRCd standards that cannot be solved anytime soon. People should be aware of this limitation.
|
||
|
|
Note that this limitation has always also been applied to channels, in which nearly all characters were always
|
||
|
|
permitted and US-ASCII casemapping was always performed.</p>
|
||
|
|
<p>NOTE 3: The basic nick characters (a-z A-Z 0-9 [ \ ] ^ _ - { | }) are always allowed/included.</p>
|
||
|
|
|
||
|
|
Example 1, for people of western europe:<br>
|
||
|
|
<pre>set { allowed-nickchars { latin1; }; };</pre>
|
||
|
|
Example 2, if you have mainly chinese users and want to allow "normal" chinese characters:<br>
|
||
|
|
<pre>set { allowed-nickchars { chinese-simp; chinese-trad; }; };</pre>

<p>Having correct time is extremely important for IRC servers. Without correct time, channels can desynch, innocent

|
|
users can be killed, channels might not show up properly in /LIST, in short: huge trouble will arrise.</p>
|
||
|
|
<p>UnrealIRCd has some build-in time synchronization support.
|
||
|
|
Although not optimal (time can still be off a few seconds), it should get rid of most time differences.
|
||
|
|
If you can, you are still recommended to run time synchronization software such as ntpd on *NIX or
|
||
|
|
the time synchronization service on Windows (in that case, you can turn off Unreal's time synchronization, more on that later).</p>
|
||
|
|
<p>What UnrealIRCd does (by default) is do a one-shot timesync attempt when booting. It sends (by default) a request
|
||
|
|
to multiple time servers and when it gets the first (fastest) reply, it will adjust the internal ircd clock
|
||
|
|
(NOT the system clock). If, for some reason, Unreal does not get a reply from the timeserver within 3 seconds,
|
||
|
|
the IRCd will continue to boot regardlessly (should rarely happen).</p>
|
||
|
|
<p>Time synchronization is configured (and can be turned off) through the <b>set::timesynch</b> block, see

|

|
|
</p>
|
||
|
|
<p>The new system uses a block-based format. Each entry, or block, in the new
|
||
|
|
format has a specific format. The format works like:</p>
|
||
|
|
<pre>
|
||
|
|
<block-name> <block-value> {
|
||
|
|
<block-directive> <directive-value>;
|
||
|
|
};
|
||
|
|
</pre></p>
|
||
|
|
<p><block-name> is the type of block, such as me, or admin. <block-value>
|
||
|
|
sometimes specifies a value, such as /oper login, but other times it will be
|
||
|
|
a sub-type such as in ban user.</p>
|
||
|
|
<p><block-directive> is an individual variable specific to the block, and
|
||
|
|
<directive-value> is the Associated value. If <directive-value>
|
||
|
|
contains spaces, or characters that represents a comment it must be contained
|
||
|
|
in double quotes. If you want to use a quote character inside a quoted string
|
||
|
|
use \" and it will be understood as a quote character.</p>
|
||
|
|
<p> A <block-directive> can have directives within it, if that’s the
|
||
|
|
case it will have it's own set of curly braces surrounding it. Some blocks do
|
||
|
|
not have directives and are specified just by <block-value>, such as include.
|
||
|
|
Also note that there is no set format, meaning the whole block can appear on
|
||
|
|
one line or over multiple lines. The format above is what is normally used (and
|
||
|
|
what will be used in this file) because it is easy to read. </p>
|
||
|
|
<p>Note: the configuration file is currently case sensitive so <i>BLOCK-NAME</i> is not
|
||
|
|
the same as <i>block-name</i>. There is a special notation used to talk about entries
|
||
|
|
in the config file. For example, to talk about <directive-name> in the
|
||
|
|
example above, you'd say <block-name>::<block-directive>, and if
|
||
|
|
that directive has a sub block you want to reverence, you would add another
|
||
|
|
:: and the name of the sub directive. </p>
|
||
|
|
<p>To talk about an unnamed directive you would do <block-name>:: which
|
||
|
|
would in this case mean <block-value>, or it could be an entry in a sub
|
||
|
|
block that has no name.</p>
|
||
|
|
<p>Three types of comments are supported:</p>
|
||
|
|
<p> # One line comment<br>
|
||
|
|
// One line comment<br>
|
||
|
|
/* Multi line<br>
|
||
|
|
comment */<br>
|
||
|
|
</p>
|
||
|
|
<p>Now that you know how it works, copy <i>doc/example.conf</i> to your UnrealIRCd
|
||
|
|
directory (eg: /home/user/Unreal3.2) and rename it to <i>unrealircd.conf</i>
|
||
|
|
(OR create your <i>unrealircd.conf</i> from scratch).
|
||
|
|

<p>These values are pretty obvious. The <b>name</b> specifies the name of the server,
|
||
|
|
<b>info</b> specifies the server's info line, <b>numeric</b> specifies a numeric to
|
||
|
|
identify the server. This must be a value between 0 and 254 that is UNIQUE to
|
||
|
|
the server meaning NO other servers on the network may have the same numeric.</p>

<p>Class blocks are classes in which connections will be placed (for example from allow blocks
|
||
|
|
or servers from link blocks), you generally have multiple class blocks (ex: for servers, clients, opers).</p>
|
||
|
|
<p><b>name</b> is the descriptive name, like "clients" or "servers", this name is
|
||
|
|
used for referring to this class from allow/link/oper/etc blocks</p>
|
||
|
|
<p><b>pingfreq</b> is the number of seconds between PINGs from the server (something between 90 and 180 is recommended).</p>
|
||
|
|
<p><b>connfreq</b> is used only for servers and is the number of seconds between connection attempts if autoconnect is enabled</p>
|
||
|
|
<p><b>maxclients</b> specifies the maximum (total) number of clients/servers which can be in this class</p>
|
||
|
|
<p><b>sendq</b> specifies the amount of data which can be in the send queue (very high for servers with low bandwidth, medium for clients)</p>
|
||
|
|
<p><b>recvq</b> specifies the amount of data which can be in the receive queue and is used for flood control
|
||
|
|
(this only applies to normal users, try experimenting with values 3000-8000, 8000 is the default).</p>

<p>The allow class is where you specify who may connect to this server, you can have multiple allow blocks.</p>
|
||
|
|
<p><b>About matching</b><br>
|
||
|
|
The access control works like this: ip matches OR host matches, so "hostname *@*"; and "ip *@1.2.3.4"
|
||
|
|
will mean it will always match. Also the allow blocks are read upside down, so you need specific host/ip allow blocks
|
||
|
|
AFTER your general *@* allow blocks. Additionally, if you want to setup a block that only matches based on IP, then set
|
||
|
|
the hostname to something invalid, such as "hostname NOBODY;", this will allow the block to only match based on IP.</p>
|
||
|
|
<p><b>ip</b><br>
|
||
|
|
The ip mask is in the form user@ip, user is the ident and often set at *, ip is the ipmask.
|
||
|
|
Some examples: *@* (from everywhere), *@192.168.* (only from addr's starting with 192.168), etc.</p>
|
||
|
|
<p><b>host</b><br>
|
||
|
|
Also a user@host hostmask, again.. user is often set at *. Some examples: *@* (everywhere),
|
||
|
|
*@*.wanadoo.fr (only from wanadoo.fr).</p>
|
||
|
|
<p><b>password</b> (optional)<br>
|
||
|
|
Require a connect password. You can also specify an password encryption method here.
|
||
|
|
</p>
|
||
|
|
<p><b>class</b><br>
|
||
|
|
Specifies the class name that connections using this allow block will be placed into.
|
||
|
|
</p>
|
||
|
|
<p><b>maxperip</b> (optional, but recommended)<br>
|
||
|
|
Allows you to specify how many connections per IP are allowed to this server (ex: maxperip 4;).
|
||
|
|
</p>
|
||
|
|
<p><b>redirect-server</b> (optional)<br>
|
||
|
|
If the class is full, redirect users to this server (if clients supports it [mIRC 6 does]).</p>
|
||
|
|
<p><b>redirect-port</b> (optional)<br>
|
||
|
|
If redirect-server is specified you can set the port here, otherwise 6667 is assumed.</p>
|
||
|
|
<p><b>options block</b> (optional)<br>
|
||
|
|
Valid options are:<br>
|
||
|
|
<b>useip</b> always display IP instead of hostname<br>
|
||
|
|
<b>noident</b> don't use ident but use username specified by client<br>
|
||
|
|
<b>ssl</b> only match if this client is connected via SSL<br>
|
||
|
|
<b>nopasscont</b> continue matching if no password was given (so you can put clients in special classes
|
||
|
|
if they supply a password).
|
||
|
|
<p>Examples:<br>
|
||
|
|
<pre>
|

<p>This block allows you to specify the ports on which the IRCD will listen. If
|
||
|
|
no options are required, you may specify this without any directives in the
|
||
|
|
form listen <ip:port>;.</p>
|
||
|
|
<p><b>ip and port</b><br>
|
||
|
|
You can set ip to * to bind to all available ips, or specify one to only bind to that ip (usually needed at shell providers).
|
||
|
|
The port is the port you want to listen on. You can also set the port to a range rather than an individual
|
||
|
|
value. For example, 6660-6669 would listen on ports 6660 through 6669 (inclusive). IPv6 users, see below.</p>
|
||
|
|
<p><b>Info for IPv6 users</b><br>
|
||
|
|
If you have an IPv6 enabled server you need to enclose the IP in brackers.
|
||
|
|
Like [::1]:6667 (listen at localhost on port 6667). If you are using IPv6 and you
|
||
|
|
want to listen at a specific IPv4 addr you need to use ::ffff:ipv4ip. For example:
|
||
|
|
[::ffff:203.123.67.1]:6667 which will listen at 203.123.67.1 on port 6667.
|
||
|
|
Of course you can also just use *.</p>
|
||
|
|
<p><b>options block</b> (optional)<br>
|
||

You can specify special options for this port if you want, valid options are:<br>

<p>The oper block allows you to assign IRC Operators for your server. The <b>oper::</b>
|
||
|
|
specifies the login name for the /oper. The <b>oper::from::userhost</b> is a user@host
|
||
|
|
mask that the user must match, you can specify more than one hostmask by creating
|
||
|
|
more than one oper::from::userhost. The <b>oper::password</b> is the password the user
|
||
|
|
must specify, oper::password:: allows you to specify an authentication method
|
||
|
|
for this password, valid auth-types are crypt, md5, and sha1, ripemd-160. If
|
||
|
|
you want to use a plain-text password leave this sub-block out.</p>
|
||
|
|
<p>Please note that BOTH the login name and password are case sensitive</p>
|
||
|
|
<p>The <b>oper::class</b> directive specifies the name of a preexisting (appears before
|
||
|
|
this in the config file) class name that the oper block will use.</p>
|
||
|
|
<p>The <b>oper::flags</b> directive has two formats. If you wish to use the old style
|
||
|
|
oper flags i.e., OAa, you use the flags <flags> method, if you want to
|
||
|
|
use the new style,i.e., services-admin, then you use the flags { <flag>;
|
||
|
|
} method. Below is a list of all the flags (in both formats) and what they do.</p>

OperOverride are things like: joining a +ikl channel and going through bans (you need to /invite yourself first however),
|
||
|
|
op'ing yourself in a channel, etc.<br>
|
||
|
|
The can_override operflag was added as an attempt to stop oper abuse.
|
||
|
|
No oper is able to override by default, you would have to give them the can_override flag explicitly.

You can enter this string using MB for megabytes, KB, for kilobytes, GB, for

gigabytes. The <b>log::flags</b> specifies which types of information will be in this

The tld::shortmotd, tld::opermotd, and tld::botmotd are optional. <b>tld::channel</b>
|

is optional as well, it allows you to specify a channel that this user will be forced

The <b>tld::options</b> block allows you to define additional requirements,

currently only tld::options::ssl which only displays the file for SSL users, and

tld::options::remote which only displays the file for remote users, exists.</p>

<p>This block disables a server's ability to connect to the network. If the server links

<p>The ban version block allows you to ban a client based on the IRC client software they use.
|

|
|
This makes use of the clients CTCP version reply. Therefore if a client does not
|
||
|
|
send out a CTCP version, the ban will not work. This feature is intended to allow you to block
|
||
|
|
malicious scripts. The <b>ban::mask</b> specifies the version which should be banned.
|
||
|
|
The mask may contain wildcards. The <b>ban::reason</b> specifies the reason why this
|
||
|
|
ban is being placed. You can also specify <b>ban::action</b>, <i>kill</i> is the default,
|
||
|
|
<i>tempshun</i> will shun the specific user connection only and would work very effective against
|
||
|
|
zombies/bots at dynamic IPs because it won't affect innocent users. <i>shun/kline/zline/gline/gzline</i>
|

will place a ban of that type on the ip (*@IPADDR), the duration of these bans can be configured

with set::ban-version-tkl-time and defaults to 1 day.</p>

<p>This block allows you to deny a server from linking based on the version of

|
Unreal it is running and what compile time options it has. The format for this
|
||
|
|
block is somewhat complex but isn't too hard to figure out. The deny::mask directive
|
||
|
|
specifies a wildcard mask of the server name this applies to. The deny::version
|
||
|
|
specifies the protocol number of the version this refers to.</p>
|
||
|
|
<p>For example, 3.0 is 2301, 3.1.1/3.1.2 is 2302, 3.2 is 2303. The first character
|
||
|
|
of this parameter can be one of the following >, <, =, !. This character
|
||
|
|
tells the IRCd how to interpret the version. If the first character is a >
|
||
|
|
then all version greater than the specified version are denied, if it is a <
|
||
|
|
all versions lower are denied, if it is an = only that version is denied, and
|
||
|
|
if it is a ! then all versions except the specified are denied. The deny::flags
|
||
|
|
directive allows you to specify what compile time flags the server may or may
|
||
|
|
not have. The flags are arranged one after the other with no separation between,
|
||
|
|
if a character is prefixed by a ! then it means the server may not have this
|
||
|
|
flag compiled into it, if it does not have a ! prefix, then it means the server
|
||
|
|
must have this flag compiled.</p>

<p>This block allows you to use specific rules to deny a server from linking.
|
||
|
|
The deny::mask specifies a wildcard mask of the server name to apply this rule
|
||
|
|
to. The deny::rule directive is very complex. A crule expression allows you
|
||
|
|
to control the link in great detail, and it is set up like a programming expression.
|
||
|
|
Four operators are supported, connected(<servermask>), returns true if
|
||
|
|
a server matching servermask is connected, directcon(<servermask>), returns
|
||
|
|
true if the server matching servermask is directly connected to this server,
|
||
|
|
via(<viamask>,<servermask>), returns true if a server matching servermask
|
||
|
|
is connected by a server matching viamask, and directop(), which returns true
|
||
|
|
if the operator issuing a /connect is directly connected to this server. These
|
||
|
|
operators can be combined using && (and) and || (or), items may also
|
||
|
|
be enclosed in parenthesis to allow grouping. In addition, an operator preceded
|
||
|
|
with a ! checks if the operator returned false. If the entire expression evaluates
|
||
|
|
to true, then the link is denied. The deny::type allows two different values,
|
||
|
|
auto (only applies to autoconnects, /connect will still work), and all (applies
|
||
|
|
to all connection attempts).</p>

|
may not join, and the <b>deny::reason</b> specifies the reason why the channel may
|
||
|
|
not be joined. Additionally, you may specify a <b>deny::redirect</b>. If this is specified,
|

|
|
when a user tries to join a channel that matches deny::channel, he/she will be redirected
|

|
|
to deny::redirect. And there's also <b>deny::warn</b> which (if set to on) will send an

opernotice (to EYES snomask) if the user tries to join.

|

|
|
<p>The badword block allows you to manipulate the list used for user and channel
|
||
|
|
mode +G to strip "badwords". The badword:: specifies the type, valid
|
||
|
|
types are channel, message, quit, and all. channel is for the channel +G list, message
|
||
|
|
is for the user +G list, quit is for quit message censoring, and all adds it to all three lists.
|
||
|
|
The badword::word can be a simple word or a regular expression we should search for. The
|
||
|
|
badword::replace is what we should replace this match with. If badword::replace
|
||
|
|
is left out, the word is replaced with <censored>. The badword::action defines
|
||
|
|
what action should be taken if this badword is found. If you specify replace, then the
|
||
|
|
badword is replaced, if you specify block, then the entire message is blocked. If you do
|

not specify a badword::action, replace is assumed.</p>

<p>This is the block you need for linking servers, please take your time to read all
|
||
|
|
this because this one of the hardest things to do and users often make errors ;P</p>
|
||
|
|
<p>First of all <b>server-name</b> is the name of your remote server, the name the remote
|
||
|
|
server has in his me { } block, like hub.blah.com (not the IP and can be different than hostname).</p>
|
||
|
|
<p><b>username</b><br>
|
||
|
|
You can specify this if you use ident for authentication, normally you will set this to "*".
|
||
|
|
</p>
|
||
|
|
<p><b>hostname</b><br>
|
||
|
|
The remote host or IP of the remote server. This is used for both connecting AND for
|
||
|
|
authentication/verification on the incoming side. Some examples:<br>
|
||
|
|
<table border="0">
|
||
|
|
<tr><td><i>1.2.3.4</i></td><td> normal IP</td></tr>
|
||
|
|
<tr><td><i>hub.blah.com</i></td><td> host: only for outgoing, cannot accept _incoming_ connections unless
|
||
|
|
link::options::nohostcheck is present</td></tr>
|
||
|
|
<tr><td><i>*</i></td><td> cannot connect TO but will allow a server connection (with correct password) from everywhere</td></tr>
|
||
|
|
<tr><td><i>::ffff:1.2.3.4</i></td><td> for linking ipv6 to ipv4.</td></tr>
|
||
|
|
</table>
|
||
|
|
</p>
|
||
|
|
<p><b>bind-ip</b> (optional)<br>
|
||
|
|
Can be used to bind to a specific IP (ex: 192.168.0.1) from where we should
|
||
|
|
connect from, almost never used.
|
||
|
|
</p>
|
||
|
|
<p><b>port</b><br>
|
||
|
|
Port to connect to (at which the remote server is listening).
|
||
|
|
</p>
|
||
|
|
<p><b>password-connect</b><br>
|
||
|
|
The password used for connecting to the remote server, must be plain-text.
|
||
|
|
</p>
|
||
|
|
<p><b>password-receive</b><br>
|
||
|
|
The password used for validating incoming links, can be encrypted (valid methods
|
||
|
|
are crypt, md5, sha1, ripemd-160). You can leave the auth-type parameter out to
|
||
|
|
just use plain-text. Often this password is the same as your password-connect.
|
||
|
|
</p>
|
||
|
|
<p><b>hub vs leaf</b><br>
|
||
|
|
A hub has multiple servers linked to it, a leaf has only one link... to you.
|
||
|
|
A server is a leaf unless it has a hub directive. It is also a leaf if the leaf directive is *, or leafdepth is 1.
|
||
|
|
</p>
|
||
|
|
<p><b>hub</b> (optional)<br>
|
||
|
|
The value is a mask of what servers this hub may connect (ex: *.my.net).
|
||
|
|
</p>
|
||
|
|
<p><b>leaf</b> (optional)<br>
|
||
|
|
The value is a mask of what servers this hub may <b>not</b> connect. Saying * here would be the same as not having a hub directive.
|
||
|
|
</p>
|
||
|
|
<p><b>leafdepth</b> (optional)<br>
|
||
|
|
The value specifies the depth (number of hops) this server may have beneath it. For example, 1 means the server can't have any links under it (a leaf), 2 means it can link servers but those servers can't link anything under them (that is, this hub can only link leaves). A value of 0 means no limit, and is the default.
|
||
|
|
</p>
|
||
|
|
<p><b>class</b><br>
|
||
|
|
The class this server is put into, often a separate server class is used for this.
|
||
|
|
</p>
|
||
|
|
<p><b>compression-level</b> (optional)<br>
|
||
|
|
Specifies the compression level (1-9) for this link. Only used if link::options::zip is set.
|
||
|
|
</p>
|
||
|
|
<p><b>ciphers</b> (optional)<br>
|
||
|
|
Specifies the SSL ciphers to use for this link. To obtain a list of available ciphers, use
|
||
|
|
the `openssl ciphers` command. Ciphers should be specified as a : separated list.
|
||
|
|
</p>
|
||
|
|
<p><b>options block</b><br>
|
||
|
|
One or more options used for connecting to the server. Sometimes not needed.<br>
|
||
|
|
<table border="0">
|
||
|
|
<tr><td><b>ssl</b></td><td> if you are connecting to a SSL port.</td></tr>
|
||
|
|
<tr><td><b>autoconnect</b></td><td> server will try to autoconnect, time specified in your class::connfreq
|
||
|
|
(it's best to enable this only from one side, like leaf->hub)</td></tr>
|
||
|
|
<tr><td><b>zip</b></td><td> if you want compressed links, needs to be compiled in + set at both ends</td></tr>
|
||
|
|
<tr><td><b>nodnscache</b></td><td> don't cache IP for outgoing server connection, use this if it's an often
|
||
|
|
changing host (like dyndns.org)</td></tr>
|
||
|
|
<tr><td><b>nohostcheck</b></td><td> don't validate the remote host (link::hostname), use this if it's an often
|
||
|
|
changing host (like dyndns.org)</td></tr>
|
||
|
|
<tr><td><b>quarantine</b></td><td> opers on this server cannot get GLOBAL oper privileges
|
||
|
|
(they will get killed), used for test links and such</td></tr>

<p>(Note: also see <a href="#includedirective">here</a> about the standard alias files UnrealIRCd has)</p>
|
||
|
|
<p>The alias block [standard alias] allows you to forward a command to a user,
|
||
|
|
for example /chanserv sends a message to the user chanserv. The alias:: specifies
|
||
|
|
the name of the command that will be the alias (eg: chanserv), alias::target is
|
||
|
|
the nickname or channel it will forward to, if the alias:: is the same as the target, it will
|
||
|
|
forward to, alias::target can be left out. The alias::type specifies the type
|
||
|
|
of alias, valid types are services (the user is on the services server), stats
|
||
|
|
(the user is on the stats server), normal (the user is a normal user on
|
||
|
|
any server), and channel (the target is a channel name). If alias::spamfilter (optional)
|
||
|
|
is set to 'yes', then the spamfilters will be checked (default is 'no').<br>
|
||
|
|
The alias block also has another purpose which is explained below.</p>
|
||
|
|
<p>Syntax [command alias]:<br>
|
||
|
|
<pre>
|
||
|
|
alias <name> {
|
||
|
|
/* For aliases to be sent to users/channels */
|
||
|
|
format <regex-expression> {
|
||
|
|
target <nick-to-forward-to>;
|
||
|
|
type <type-of-alias>;
|
||
|
|
parameters <parameter-string>;

type real;

parameters <parameter-string>;

type command;
|
||
|
|
spamfilter <yes|no>;
|
||
|
|
};</pre></p>
|
||
|
|
<p>When the alias block is used in this format, it allows you a much broader range
|
||
|
|
of usage. For example you can create aliases such as /identify. The alias::
|
||
|
|
is the same as above, the name of the alias command. The <b>alias::format</b> specifies
|
||
|
|
a regular expression that compares against the text sent to the alias command,
|
||
|
|
when matched the sub-entries of that alias::format will be used, you may have
|
||
|
|
multiple alias::format's to make the command do different things depending on
|
||
|
|
the text sent to it. The <b>alias::format::target</b> is the target to forward this
|
||
|
|
alias to, however in case of a "real alias" <b>alias::format::command</b> is used instead.
|
||
|
|
The <b>alias::format::type</b> specifies the type of the alias that the
|
||
|
|
message should be forwarded to, besides the types mentioned previously in
|
||
|
|
"Syntax [standard alias]", we also allow the type "real" here, for "real
|
||
|
|
aliases". The <b>alias::format::parameters</b> is what will
|
||
|
|
be sent as the parameters to this alias. To specify one of the parameters given
|
||
|
|
to the command alias specify % followed by a number, for example, %1 is the
|
||
|
|
first parameter. To specify all parameters from a given parameter to the end
|
||
|
|
do % followed by the number and a -, for example %2- returns all parameters
|
||
|
|
from the second till the last. Additionally, you may specify %n which will be replaced
|
||
|
|
by the nickname of the user who executed the command.<br><br>

The cgiirc block allows you to configure host spoofing for CGI:IRC gateways you trust
|
||
|
|
(<a href="#feature_cgiirc">more info</a>).</p>
|
||
|
|
|
||
|
|
<p>Syntax:<br>
|
||
|
|
<pre>
|
||
|
|
cgiirc {
|
||
|
|
type <webirc|old>;
|
||
|
|
username <mask>; /* optional */
|
||
|
|
hostname <mask>;
|
||
|
|
password <password>; /* only for type webirc */
|
||
|
|
};</pre></p>
|
||
|
|
<p><b>type</b> is either 'webirc' or 'old'.<br>
|
||
|
|
<b>username</b> is matched against the ident (if present). If not specified, "*" is assumed.<br>
|
||
|
|
<b>hostname</b> is the hostmask to match against.<br>
|
||
|
|
<b>password</b> is the webirc password, only used for type 'webirc'.<br>
|
||
|
|
</p>
|
||
|
|
|
||
|
|
<p><b>How to configure with method 'webirc' (recommended method)</b><br>
|
||
|
|
In your CGI:IRC configuration file (cgiirc.conf) you set webirc_password to a good password.<br>
|
||
|
|
Then, in your unrealircd.conf you add a cgiirc block to allow this host and password and you set
|
||
|
|
cgiirc::type to "webirc".<br>
|
||
|
|
<br>
|
||
|
|
Example:<br>
|
||
|
|
In your CGI:IRC configuration file (cgiirc.conf) you add:
|
||
|
|
<pre>webirc_password = LpT4xqPI5</pre>
|
||
|
|
Then, in your unrealircd.conf you add a cgiirc block:
|
||
|
|
<pre>cgiirc {
|
||
|
|
type webirc;
|
||
|
|
hostname "1.2.3.4";
|
||
|
|
password "LpT4xqPI5";
|
||
|
|
};</pre></p>
|
||
|
|
|
||
|
|
<p><b>How to configure with method 'old'</b><br>
|
||
|
|
NOTE: This is not the recommended method since it has two disadvantages:
|
||
|
|
this method will send the IP/host to spoof as a server password, meaning you cannot
|
||
|
|
specify a server password as a CGI:IRC user. Additionally, access control is only
|
||
|
|
IP-based and does not require an extra password like the 'webirc' method. In short,
|
||
|
|
you probably should not be using this method unless you have a good reason to do so.<br>
|
||
|
|
<br>
|
||
|
|
In your CGI:IRC configuration file (cgiirc.conf) you set realhost_as_password to 1.<br>
|
||
|
|
Then, in your unrealircd.conf you add a cgiirc block to allow this host.<br>
|
||
|
|
<br>
|
||
|
|
Example:<br>
|
||
|
|
In your CGI:IRC configuration file (cgiirc.conf) you add:
|
||
|
|
<pre>realhost_as_password = 1</pre>
|
||
|
|
Then, in your unrealircd.conf you add a cgiirc block:
|
||
|
|
<pre>cgiirc {
|
||
|
|
type old;
|
||
|
|
hostname "1.2.3.4";
|
||
|
|
};</pre></p>

|

|
|
<font class="block_required">REQUIRED</font> <font class="block_old">(Previously known as unrealircd.conf/networks file)</font><a name="setblock"></a>
|
||
|
|
</p><div class="desc">
|
||
|
|
<p>The set file is what use to be our networks/unrealircd.conf and our networks
|
||
|
|
file. On single server networks, rather than having 3 files you can just put all
|
||
|
|
the set statements in the unrealircd.conf itself, on multi-server networks, I
|
||
|
|
recommend using a seperate networks file.</p>
|
||
|
|
<p>Now, if your server is on a network, chances are you will all basically use
|
||
|
|
the same Set settings. Therefore it makes more sense to have a network file,
|
||
|
|
which is loaded with an <a href="#includedirective">include</a> directive.
|
||
|
|
Below you will find all of the set directives available.</p>
|
||
|
|
<p>In this doc we refer to settings / directives in the <block-name>::<block-directive>
|
||
|
|
format. This format is NOT the format that it can be entered into the configuration
|
||
|
|
file. IT MUST be converted to the format listed below. It is presented in the
|
||
|
|
format it is to make discussing it simpler.</p>
|
||
|
|
<p>Syntax:<br>
|
||
|
|
<pre>
|
||
|
|
set {
|
||
|
|
<entry> <value>;
|
||
|
|
<entry> <value>;
|
||
|
|
...
|
||
|
|
};</pre></p>
|
||
|
|
<p>The set block sets options for individual server features. Each entry does
|
||
|
|
something different and therefore each will be described below. Some directives
|
||
|
|
have sub blocks which will also be described. There are many set statements
|
||
|
|
to cover, all of the directives listed below can be included under ONE set statement.
|
||
|
|
If a directive has options, they are included within the single set statement
|
||
|
|
as well.<br>
|
||
|
|
Example:<br>
|
||
|
|
<pre>
|
||
|
|
set {
|
||
|
|
kline-address my@emailaddress.com;
|
||
|
|
auto-join #welcome;
|
||
|
|
options {
|
||
|
|
hide-ulines;
|
||
|
|
};
|
||
|
|
hosts {
|
||
|
|
local LocalOp.MyNet.com;
|
||
|
|
global globalop.mynet.com;
|
||
|
|
};
|
||
|
|
};</pre></p>
|
||
|
|
<p>Now if you wanted to make the set statements separate, say you wanted to set
|
||
|
|
your options in a single line.<br>
|
||
|
|
Example:<br>
|
||
|
|
set { options { hide-ulines; no-stealth; }; };<br>
|
||
|
|
</p>
|
||
|
|
<p><font class="set">set::kline-address <email-address>;</font><br>
|
||

||
|
|
specified.</p>
|
||
|
|
<p><font class="set">set::gline-address <email-address>;</font><br>
|
||
|

The email address that G:line questions should be sent to.</p>
|

<p><font class="set">set::snomask-on-connect <+modes></font><br>
|
||
|

|
|
<p><font class="set">set::modes-on-oper <+modes>;</font><br>
|
||
|

|
<p><font class="set">set::snomask-on-oper <+modes>;</font><br>
|

The snomask that will be set on a user when they /oper.</p>
|
||
|
|
<p><font class="set">set::modes-on-join <+modes>;</font><br>
|
||
|
|
The modes that will be set on a channel when it is first created. Not all modes can be set using this command. +qaohvbeOAzlLk can NOT be set using this command.</p>
|
||
|
|
<p><font class="set">set::level-on-join <none|voice|halfop|op|protect|owner>;</font><br>
|
||
|
|
The mode that a user will get when he's the first to join a channel. The
|
||
|
|
default is 'op' (channel operator).</p>
|
||
|
|
<p><font class="set">set::restrict-usermodes <modes></font><br>
|
||
|
|
Restrict users to set/unset the modes listed here (don't use + or -).<br>
|
||
|
|
For example you can set +G in modes-on-connect and G in restrict-usermodes,
|
||
|
|
that way you can force all users to be +G and unable to do -G.</p>
|
||
|
|
<p><font class="set">set::restrict-channelmodes <modes></font><br>
|
||
|
|
Restrict users to set/unset the channelmodes listed here (don't use + or -).<br>
|
||
|
|
For example you can set +G in modes-on-join and G in restrict-channelmodes,
|
||
|
|
that way you can force all (new) channels to be +G and unable to do -G.<br>
|
||
|
|
NOTE: it may still be possible to use these channelmodes through services
|
||
|
|
by using MLOCK. Unfortunately we can't do much about that, you would have
|
||
|
|
to ask the services coders to implement a restrict-channelmodes feature too.</p>
|
||
|
|
<p><font class="set">set::restrict-extendedbans <types|*></font><br>
|
||

Don't allow users to use any extended bans ("*") or disallow only certain ones (eg: "qc").</p>
|
||
|
|
<p><font class="set">set::auto-join <channels>;</font><br>
|
||
|
|
The channel(s) a user will be forced to join at connection. To specify more
|
||
|
|
than one channel use a comma separated list.<br>
|
||
|
|
[Note: don't forget to add quotes, like: auto-join "#chan";]</p>
|
||
|
|
<p><font class="set">set::oper-auto-join <channels>;</font><br>
|
||
|
|
The channel(s) a user will be forced to join when they /oper. To specify more
|
||
|
|
than one channel use a comma separated list.<br>
|

[Note: don't forget to add quotes, like: oper-auto-join "#chan";]</p>
|
||
|
|
<p><font class="set">set::anti-spam-quit-message-time <timevalue>;</font><br>
|
||
|
|
A time value specifying the length of time a user must be connected for before
|
||
|
|
a /quit message will be displayed. Used to prevent spam. A time value is a numeric
|
||
|
|
string with d meaning days, h meaning hours, m meaning minutes, and s meaning
|
||
|
|
seconds, for example 1d2h3m means 1 day, 2 hours, 3 minutes.</p>
|
||
|
|
<p><font class="set">set::prefix-quit <text-to-prefix-quit>;</font><br>
|
||
|
|
Sets the text that will be used to prefix a quit message. If this value is set
|
||
|
|
to 0 then the standard "Quit:" is used.</p>
|
||
|
|
<p><font class="set">set::static-quit <quit message>;</font><br>
|
||
|
|
Sets a static quit message that will be sent whenever a client logs off the
|
||
|
|
network. This eliminates the need for anti-spam-quit-message-time, as well as
|
||
|
|
the set::prefix-quit. It will NOT replace ERRORS with the static-quit message.</p>
|
||
|
|
<p><font class="set">set::static-part <no|yes|part message>;</font><br>
|
||
|
|
A value of 'yes' strips all part comments, a value of 'no' makes part just work
|
||
|
|
as usual, anything else will be used as a part comment (eg: static-part "Bye!")
|
||
|
|
but this can be quite annoying, so use with care.</p>
|
||
|
|
<p><font class="set">set::who-limit <limit>;</font><br>
|
||
|
|
Sets the limit for the maximum number of matches that will be returned for a /who.
|
||
|
|
If this option is left out, no limit is enforced.</p>
|
||
|
|
<p><font class="set">set::silence-limit <limit>;</font><br>
|
||
|
|
Sets the limit on the maximum SILENCE list entries. If this directive is not specified,
|
||
|
|
a limit of 15 is set.</p>
|
||
|
|
<p><font class="set">set::maxbans <limit>;</font><br>
|
||
|
|
Sets the limit on the maximum amount of bans (+b) allowed per channel. The default is 60.
|
||
|
|
If you change this, be sure to also take a look at maxbanlength (see next)!</p>
|
||
|
|
<p><font class="set">set::maxbanlength <limit>;</font><br>
|
||
|
|
Similar to above, but sets the maximum amount of characters for all bans added up
|
||
|
|
together, so basically this puts up a limit on the (semi-)maximum amount of memory
|
||
|
|
all channel bans on a channel can take. The default is 2048 (bytes). With the default
|
||
|
|
set::maxbans of 60 this allows 2048:60=34 characters per ban on average.</p>
|
||
|
|
<p><font class="set">set::oper-only-stats <stats-list>;</font><br>
|
||
|
|
Specifies a list of stats flags with no separators that defines stats flags
|
||
|
|
only opers can use. Leave this value out to allow users to use all flags, or
|
||
|
|
specify * for users to be able to use no flags. Only short stats flags may be specified
|
||
|
|
here.</p>
|
||
|
|
<p><font class="set">set::oper-only-stats {<stats-flag>; <stats-flag>;};</font><br>
|
||
|
|
Specifies a list of stats flags that can only be used by opers. This only works with long
|
||
|
|
stats flags.</p>
|
||
|
|
<p><font class="set">set::maxchannelsperuser <amount-of-channels>;</font><br>
|

|
|
Specifies the number of channels a single user may be in at any one time.</p>
|
||
|
|
<p><font class="set">set::maxdccallow <amount-of-entries>;</font><br>
|
||
|
|
Specifies the maximum number of entries a user can have on his/her DCCALLOW list.</p>
|
||
|
|
<p><font class="set">set::channel-command-prefix <command-prefixes>;</font><br>
|
||
|
|
Specifies the prefix characters for services "in channel commands". Messages starting with
|
||
|
|
any of the specified characters will still be sent even if the client is +d. The default
|
||
|
|
value is "`!.".</p>
|
||
|
|
<p><font class="set">set::allowed-nickchars { <list> };</font><br>

|
||
|
|
<p><font class="set">set::allow-userhost-change [never|always|not-on-channels|force-rejoin]</font><br>
|
||
|
|
Specifies what happens when the user@host changes (+x/-x/chghost/chgident/setident/vhost/etc).<br>
|
||
|
|
<i>never</i> disables all the commands, <i>always</i> does always allow it even when in channels
|
||
|
|
(may cause client desyncs) [default], <i>not-on-channels</i> means it's only allowed when the
|
||
|
|
user is not on any channel, <i>force-rejoin</i> will force a rejoin in all channels and re-op/voice/etc if needed.</p>
|
||
|
|
<p><font class="set">set::options::hide-ulines;</font><br>

|
||
|
|
<p><font class="set">set::options::flat-map;</font><br>
|
||
|
|
If this is present, all servers will appear as directly linked in /map and /links,

thus you can no longer see which server is linked to which. This is a little help against

If present the presence of an identd server will be checked and the returned

|
||
|
|
identd server doesn't exist, the user's specified username will be prefixed

You don't need to use a <a href="#tldblock">TLD block</a> to specify default locations for your MOTDs and rules files. This block controls default settings for those in addition to the pidfile and irc.tune file.

Relative pathnames will be interpreted relative to unrealIRCD's root directory which is normally the directory containing <tt>unrealircd.conf</tt>. This block may be used to facilitate running more than one IRCd out of the same directory/root. In that case, you should at least specify multiple pidfiles and tunefiles—one for each server.

|

There's a far bigger chance a box will get hacked by a non-irc(d) vulnerability than by some bug in UnrealIRCd.
|
||
|
|
If you for example run http, dns, smtp and ftp servers on the same box you have a much higher risk.
|
||
|
|
Also, if you are on a multi-user box (eg: you bought a shell) there's the risk of local exploits and bad permissions
|
||
|
|
(see next). This risk is quite high so be careful when selecting a shell provider.

<p><b><font size="+2">8.3 Permissions and the configfile</font></b><a name="secpermissions"></a><br><div class="desc">
|
||
|
|
Always make sure your home directory and UnrealIRCd directory have correct permissions,
|
||
|
|
(group/)other shouldn't have read permissions. Otherwise a local user can simply grab
|
||
|
|
your configfile and look for passwords... In short: <i>chmod -R go-rwx /path/to/Unreal3.2</i> if you are unsure about this.<br>
|
||
|
|
Other things related to this: never put your UnrealIRCd inside the webroot or some other
|
||
|
|
kind of shared directory. And for backups, make sure they get the correct permissions too
|
||
|
|
(it happens quite frequently everything is secured fine but there's a backup.tar.gz lying
|
||
|
|
around readable by everyone).<br>
|
||
|
|
<br>
|
||
|
|
You also want to use encrypted passwords wherever possible, if you compile with OpenSSL
|
||
|
|
support (which you do, since you are concerned with security, right?) then I suggest to
|
||
|
|
use <i>sha1</i> or <i>ripemd160</i> password encryption, else use <i>md5</i>. Also if
|
||
|
|
you still have encrypted (oper) blocks left from Unreal3.2.1 or before I suggest you to
|
||
|
|
re-enrypt these (just re-run /mkpasswd), because 3.2.1 introduced some considerable
|
||
|
|
anti-crack improvements (basically a 14x slowdown of active cracks, and making
|
||
|
|
stored-plain-ciphertext cracks impossible).<br>
|
||
|
|
Still, do note that this is just 'yet another layer of security', since if you have weak
|
||
|
|
passwords they can still be cracked relatively easily and if someone manages to get your
|
||
|
|
configfile there are usually other interesting things in it that may aid an attacker,
|
||
|
|
like link::password-connect.

Even though you are careful and did everything in this doc, maybe your friend which is an

Sniffing is possible if an attacker hacked a box somewhere between you and your ircd server,

<p><b><font size="+2">8.6 Denial of Service attacks (DoS) [or: how to protect my hub]</font></b><a name="secDoS"></a><br><div class="desc">
|
||
|
|
A lot of networks have experienced how much "fun" a flood or (D)DoS attack is, you can however
|
||
|
|
do some things to reduce the damage caused by it. Most nets have a hub server, what some people
|
||
|
|
seem to forget is that it's quite easy to protect the hub server from getting attacked.<br>
|
||
|
|
I'll explain it here:<br>
|
||
|
|
1. Set the name of the hub to a hostname that doesn't exist, eg 'hub.yournet.com', but<br>
|
||
|
|
don't add a dns record for it. This way an attacker cannot resolve the host and<br>
|
||
|
|
cannot flood it either. Then simply link your servers to the hub by specifying the<br>
|
||
|
|
IP or another non-public hostname.<br>
|
||
|
|
Example 1: <i>link visibiblename.yournet.com { hostname 194.15.123.16; [etc] };</i>.<br>
|
||
|
|
Example 2: <i>link visibiblename.yournet.com { hostname thehostnamethatworks.yournet.com; [etc] };</i>.<br>
|
||
|
|
On a sidenote, for the last example you must be sure your nameservers don't allow zone transfers,
|
||
|
|
but that's way too off-topic ;).<br>
|
||
|
|
2. Another important step is then to hide '/stats c' and other stats information, otherwise<br>
|
||
|
|
attackers can simply list your link blocks. Usually if you are this paranoid (like<br>
|
||
|
|
me) you can simply do: set { oper-only-stats "*"; }; to restrict all /stats usage.<br>
|
||
|
|
If you don't want that, at least hide "CdDlLXz". More about this in the next section.<br>
|
||
|
|
<br>
|
||
|
|
Of course those steps are less useful if they are applied afterwards (eg: after a few months)<br>
|
||
|
|
instead of at the beginning because the IP's might be already known to some evil guys, still.. it's worth to do.<br>
|
||
|
|
Also note that attackers can still flood all non-hub servers, but that requires more effort<br>
|
||
|
|
than just attacking 1 or 2 weak points (the hubs), also this way your hubs & services
|
||
|
|
will stay alive :).<br>

|

|
|
<b>STATS</b><br>
|
||
|
|
The /stats command is very informative, you probably want to restrict it's usage as much
|
||
|
|
as possible. A question you should ask yourself is "what do I want my users to see?".
|
||
|
|
Most big networks choose "nothing", while others prefer their clients to be able to do
|
||
|
|
'/stats g' and '/stats k'.<br>
|
||
|
|
I suggest you to use <i>set { oper-only-stats "*"; };</i> to deny all /stats for non-opers, but if you don't
|
||
|
|
want that, step through the '/stats' list (gives an overview of all available options) and
|
||
|
|
block everything except what you want to allow.. (if in doubt, just deny.. why should they
|
||
|
|
really need to know all this?).<br>
|
||
|
|
To give you a few examples:<br>
|
||
|
|
- /stats o: gives you the nicks of opers (with correct case) and hostmasks.<br>
|
||
|
|
- /stats c: gives you an idea about serverlinks and which to use as 'backup', etc..<br>
|
||
|
|
- /stats g, /stats k: usually used for banning proxies.. so this will simply give attackers
|
||
|
|
a list of proxies they can use.<br>
|
||
|
|
- /stats E, /stats e: pretty sensitive info, especially if an attacker can use these addresses<br>
|
||
|
|
- /stats i, /stats y: might aid an attacker in finding hosts which allow lots of connections.<br>
|
||
|
|
- /stats P: helps him find serveronly ports<br>
|
||
|
|
etc etc...<br>
|
||
|
|
<br>
|
||
|
|
<b>MAP / LINKS</b><br>
|
||
|
|
Several people have asked if there was some way to disable /map or /links.
|
||
|
|
Our position on this is that it's silly and gives a false sense of security, let me explain...
|
||
|
|
Hiding servers that are actually used by users is useless since they already know
|
||
|
|
about your servers (how else could they get on them in the first place?). For any servers that you
|
||
|
|
don't want users on, see section 8.6.<br>
|
||
|
|
Now what CAN you do? Since 3.2.1 there's an option called 'flat map' (set::options::flat-map),
|
||
|
|
this will make all servers appear as 'directly linked' in /map and /links, thus normal users
|
||
|
|
can no longer see which server is linked to which... This can be a nice additional layer
|
||
|
|
of protection because this way a kiddie cannot easily spot any 'weak points' with /map or /links.
|
||
|
|
So, use of this is recommended. Note that this is not foolproof... If any split happends someone
|
||
|
|
can still see which server was linked to which, and this is also true for some other things as well.<br>
|
||
|
|
<br>
|
||
|
|
<b>NORMAL USERS & SNOMASKS</b><br>
|
||
|
|
A feature that isn't widely known is that normal users can also set some limited snomasks,
|
||
|
|
namely +s +sk. By this they can see things like rehashes, kills and various other messages.<br>
|
||
|
|
To disable this you can use set::restrict-usermodes like this: <i>set { restrict-usermodes "s"; };</i>.<br>
|
||
|
|
|
||
|
|
|
||
|
|
<br><br>
|
||
|
|
Of course all of this is "information hiding", so it's not "true" security.
|
||
|
|
It will however make it more difficult / increase the effort needed to attack/hack.<br>
|
||
|
|

|
<p><b><font size="+2">8.8 Protecting against exploits</font></b><a name="secantiexploit"></a><br><div class="desc">
|
||
|
|
There are kernel patches that make it more difficult for stack- and heap-based exploits to
|
||
|
|
work. This is nice, but should not be your main focus point, you have a far more bigger risk
|
||
|
|
of getting exploited through the other points than this... for various reasons.<br>
|
||
|
|
Another option is enabling chrooting (*NIX only), which means upon a succesfull exploit,
|
||
|
|
the user is confined to the UnrealIRCd directory and cannot touch any other
|
||
|
|
files. This requires root privileges, modifying of include/config.h
|
||
|
|
(search for CHROOTDIR, and also set IRC_USER and IRC_GROUP), and a
|
||
|
|
recompile.<br>
|
||
|
|
<br>
|
||
|
|
There's one thing you should definately do, which is to ALWAYS USE THE LATEST VERSION,
|
||
|
|
subscribe to the <a href="http://mail1.sourceforge.net/mailman/listinfo/unreal-notify" target="_blank">unreal-notify mailinglist</a>
|
||
|
|
right now so you receive the release announcements (unreal-notify is for release announcements only,
|
||
|
|
so only 1 mail per X months). Usually it's explicitly mentioned in the release announcement if the
|
||
|
|
release contains (high risk) security fixes, but it's good to upgrade anyway.<br>

As you now hopefully understand, you can never be 100% secure. You (and us) have to
|

|
|
find&fix every hole out there, while an attacker only needs to find just 1 server with 1 hole.
|
||
|
|
Everything that was explained here DOES however help by minimizing the risks considerably.

Do take the time to secure your network and educate your opers. A lot of people don't care about

security until they got hacked, try to avoid that :).

<div class="desc"><p>Regular expressions are used in many places in Unreal, including badwords, spamfilter, and aliases. Regular expressions are a very complex tool used for pattern matching. They are sometimes referred to as "regexp" or "regex." Unreal uses the TRE regular expression library for its regex. This library supports some very complex and advanced expressions that may be confusing. The information below will help you understand how regexps work.

|
||
|
|
<div class="desc"><p>Literals are the most basic component of a regexp. Basically, they are characters that are treated as plaintext. For example, the pattern "test" consists of the four literals, "t," "e," "s," and "t." In Unreal, literals are treated as case insensitive, so the previous regex would match "test" as well as "TEST." Any character that is not a "meta character" (discussed in the following sections) is treated as a literal. You can also explicitely make a character a literal by using a backslash (\). For example, the dot (.) is a metacharacter. If you wish to include a literal ., simply use \. and Unreal will treat this as a period. It is also possible that you want to check for a character that is not easily typed, say ASCII character 3 (color). Rather than having to deal with using an IRC client to create this character, you can use a special sequence, the \x. If you type \x3, then it is interpretted as being the ASCII character 3. The number after the \x is represented as hexidecimal and can be in the range from \x0 to \xFF.</p></div>

|

|
<div class="desc"><p>The dot (.) operator is used to match "any character." It matches a single character that has any value. For example, the regex "a.c" will match "abc," "adc," etc. However, it will not match "abd" because the "a" and "c" are literals that must match exactly.</p></div>

||

||
|
|
<p><font size="+2"><b>A.3 Repetition Operators<a name="regexrep"></a></b></font></p>
|
||
|
|
<div class="desc"><p>One of the common mistakes people make with regex is assuming that they work just like wildcards. That is, the * and ? characters will match just like in a wildcard. While these characters do have similar meaning in a regex, they are not exactly the same. Additionaly, regular expressions also support other, more advanced methods of repetition.
|
||
|
|
<p>
|
||
|
|
The most basic repetition operator is the ? operator. This operator matches 0 or 1 of the previous character. This, "of the previous character," is where the ? in regex differs from a wildcard. In a wildcard, the expression, "a?c" matches an "a" followed by any character, followed by a "c". In regex it has a different meaning. It matches 0 or 1 of the letter "a" followed by the letter "c". Basically, the ? is modifying the a by specifying how many a's may be present. To emulate the ? in a wildcard, the . operator is used. The regex "a.c" is equivilent to the previously mentioned wildcard. It matches the letter "a" followed by any character, followed by a "c".
|
||
|
|
<p>
|
||
|
|
The next repetition operator is the *. Again, this operator is similar to a wildcard. It matches 0 or more of the previous character. Note that this "of the previous character" is something that is characteristic of all repetition operators. The regex "a*c" matches 0 or more a's followed by a "c". For example, "aaaaaac" matches. Once again, to make this work like a wildcard, you would use "a.*c" which will cause the * to modify the . (any character) rather than the "a."
|
||
|
|
<p>
|
||
|
|
The + operator is very similar to the *. However, instead of matching 0 or more, it matches 1 or more. Basically, "a*c" will match "c" (0 a's followed by a c), where as "a+c" would not. The "a+" states that there must be "at least" 1 a. So "c" does not match but "ac" and "aaaaaaaaac" do.
|
||
|
|
<p>
|
||
|
|
The most advanced repetition operator is known as a "boundary." A boundary lets you set exact constraints on how many of the previous character must be present. For example, you may want to require exactly 8 a's, or at least 8 a's, or between 3 and 5 a's. The boundary allows you to accomplish all of these. The basic syntax is {M,N} where M is the lower bound, and N is the upper bound. For example, the match between 3 and 5 a's, you would do "a{3,5}". However, you do not have to specify both numbers. If you do "a{8}" it means there must be exactly 8 a's. Therefore, "a{8}" is equivilent to "aaaaaaaa." To specify the "at least" example, you basically create a boundary that only has a lower bound. So for at least 8 a's, you would do "a{8,}".
|
||
|
|
<p>
|
||
|
|
By default, all of the repetition operators are "greedy." Greediness is a somewhat complex idea. Basically, it means that an operator will match as many characters as it can. This is best explained by an example. <p>Say we have the following text:<br>
|
||
|
|
HELLO<br>
|
||
|
|
And the following regex:<br>
|
||
|
|
.+L<p>
|
||
|
|
In this example, you might think that the .+ matches "HE." However, this is incorrect. Because the + is greedy, it matches "HEL." The reason is, it chooses the largest portion of the input text that can be matched while still allowing the entire regex to match. In this example, it chose "HEL" because the only other requirement is that the character after the text matched by .+ must be an "L". Since the text is "HELLO", "HEL" is followed by an "L," and therefore it matches. Sometimes, however, it is useful to make an operator nongreedy. This can be done by adding a ? character after the repetition operator. Modifying the above to, ".+?L" the .+? will now match "HE" rather than "HEL" since it has been placed in a nongreedy state. The ? can be added to any repetition character: ??, *?, +?, {M,N}?.</p></div>

|
<div class="desc">Bracket expressions provide a convenient way to do an "or" operator. For example, if you want to say "match an a or a b." The bracket expression gets its name from the fact that it is enclosed in brackets ([]). The basic syntax is that the expression includes a series of characters. These characters are then treated as though there were an "or" between them. As an example, the expression "[abc]" matches an "a," a "b," or a "c." Therefore, the regexp "a[bd]c" matches "abc" and "adc" but not "acc."

One very common thing to do is to check for things such as, a letter, or a digit. Rather than having to do, for example, "[0123456789]", the bracket operator supports ranges. Ranges work by specifying the beginning and ending point with a - between them. Therefore, a more simplistic way to test for a digit is to simply do "[0-9]". The same thing can be used on letters, or in fact, any range of ASCII values. If you want to match a letter, simply do "[a-z]" since Unreal is case insensitive, this will match all letters. You can also include multiple ranges in the same expression. To match a letter or a number, "[0-9a-z]". One complication that this creates is that the - is a special character in a bracket expression. To have it match a literal -, the easiest way is to place it as either the first or last character in the expression. For example, "[0-9-]" matches a digit or a -.

To make things even more simple, there are several "character classes" that may be used within a bracket expression. These character classes eliminate the need to define certain ranges. Character classes are written by enclosing their name in :'s. For example, "[0-9]" could also be written as "[:isdigit:]". The list below shows all of the available character classes and what they do:
|
||
|
|
<ul>
|
||
|
|
<li><tt>alnum</tt> - alphanumeric characters</li>
|
||
|
|
<li><tt>alpha</tt> - alphabetic characters</li>
|
||
|
|
<li><tt>blank</tt> - blank characters</li>
|
||
|
|
<li><tt>cntrl</tt> - control characters</li>
|
||
|
|
<li><tt>digit</tt> - decimal digits (0 through 9)</li>
|
||
|
|
<li><tt>graph</tt> - all printable characters except space</li>
|
||
|
|
<li><tt>lower</tt> - lower-case letters</li>
|
||
|
|
<li><tt>print</tt> - printable characters including space</li>
|
||
|
|
<li><tt>punct</tt> - printable characters not space or alphanumeric</li>
|
||
|
|
<li><tt>space</tt> - white-space characters</li>
|
||
|
|
<li><tt>upper</tt> - upper case letters</li>
|
||
|
|
<li><tt>xdigit</tt> - hexadecimal digits</li>
|
||
|
|
</ul>
|
||
|
|
One important note about character classes is that they MUST be the only element in the expression. For example, [:isdigit:-] is NOT legal. Instead, you can accomplish this same goal by nesting the expressions, for example, to do the same thing as "[0-9-]" using a character class, you could do "[[:isdigit:]-]".

The last feature of the bracket expression is negation. Sometimes it is useful to say "anything except these characters." For example, if you want to check if the character is "not a letter," it is easier to list a-z and say "not these," than it is to list all the non-letters. Bracket expressions allow you to handle this through negation. You negate the expression by specifying a "^" as the first character. For example, "[^a-z]" would match any non-letter. As with the -, if you want to include a literal ^, do not place it in the first position, "[a-z^]". Also, to negate a character class, you must once again use nesting, "[^[:isdigit:]]" would match any non-digit.</p></div>

|
||
|
|
<div class="desc">Assertions allow you to test for certain conditions that are not representable by character strings, as well as providing shortcuts for some common bracket expressions.
|
||
|
|
<p>
|
||
|
|
The ^ character is referred to as the "left anchor." This character matches the beginning of a string. If you simply specify a regex such as "test", it will match, for example "this is a test" since that string contains "test." But, sometimes it is useful to ensure that the string actually starts with the pattern. This can be done with ^. For example "^test" means that the text must start with "test." Additionally, the $ character is the "right anchor." This character matches the end of the string. So if you were to do "^test$", then the string must be exactly the word "test."
|
||
|
|
<p>
|
||
|
|
Similar tests also exist for words. All of the other assertions are specified using a \ followed by a specific character. For example, to test for the beginning and ending of a word, you can use \< and \> respectively.
|
||
|
|
<p>
|
||
|
|
The remaining assertions all come with two forms, a positive and a negative. These assertions are listed below:
|
||
|
|
<ul>
|
||
|
|
<li><tt>\b</tt> - Word boundary
|
||
|
|
<li><tt>\B</tt> - Non-word boundary
|
||
|
|
<li><tt>\d</tt> - Digit character (equivalent to <tt>[[:digit:]]</tt>)</li>
|
||
|
|
<li><tt>\D</tt> - Non-digit character (equivalent to <tt>[^[:digit:]]</tt>)</li>
|
||
|
|
<li><tt>\s</tt> - Space character (equivalent to <tt>[[:space:]]</tt>)</li>
|
||
|
|
<li><tt>\S</tt> - Non-space character (equivalent to <tt>[^[:space:]]</tt>)</li>
|
||
|
|
<li><tt>\w</tt> - Word character (equivalent to <tt>[[:alnum:]_]</tt>)</li>
|
||
|
|
<li><tt>\W</tt> - Non-word character (equivalent to <tt>[^[:alnum:]_]</tt>)</li>

|
||
|
|
<div class="desc">Alternation is a method of saying "or." The alternation operator is the vertical bar (|). For example, if you wanted to say "a or b" you could do "a|b". For normal letters, this could be replaced by a bracket expression, but alternation can also be used with subexpressions (discussed in the next section).

<p><font size="+2"><b>A.7 Subexpressions<a name="regexsub"></a></b></font></p>
|
||
|
|
<div class="desc">Subexpressions are a portion of of a regex that is treated as a single entity. There are two ways to create a subexpression. The two methods differ with regard to "back references," which will be explained later. To declare a subexpression that uses back references, simply enclose it in parentheses (). To create a subexpression that does not use back references, replace the open-parenthesis with, "(?:". For example, "([a-z])" and "(?:[a-z])". The reason subexpressions are useful is you can then apply operators to the expression. All of the repetition operators, for example, that were mentioned as "X or more of the previous character," can also be used for "X or more of the previous subexpression." For example, if you have a regex of "[0-9][a-z][0-9]", to match a digit, followed by a letter, followed by a digit, and then you decided you wanted to match this sequence twice. Normally, you would do, "[0-9][a-z][0-9][0-9][a-z][0-9]". With subexpressions, however, you can simply do "([0-9][a-z][0-9]){2}".</div>
|

|
|
<p><font size="+2"><b>A.8 Back References<a name="regexbackref"></a></b></font></p>
|
||
|
|
<div class="desc">Back references allow you to reference the string that matched one of the subexpressions of the regexp. You use a back reference by specifying a backslash (\) followed by a number, 0-9, for example \1. \0 is a special back reference that refers to the entire regexp, rather than a subexpression. Back references are useful when you want to match something that contains the same string twice. For example, say you have a nick!user@host. You know that there is a trojan that uses a nickname and username that matches "[0-9][a-z]{5}", and both the nickname and username are the same. Using "[0-9][a-z]{5}![0-9][a-z]{5}@.+" will not work because it would allow the nickname and username to be different. For example, the nickname could be 1abcde and the username 2fghij. Back references allow you to overcome this limitation. Using, "([0-9][a-z]{5})!\1@.+" will work exactly as expected. This searches for the nickname matching the given subexpressions, then it uses a back reference to say that the username must be the same text.
|
||
|
|
<p>
|
||
|
|
Since you can only have 9 back references, this is the reason why the (?:) notation is useful. It allows you to create a subexpression without wasting a back reference. Additionally, since back reference information does not need to be saved, it is also faster. Because of this, non-back reference subexpressions should be used whenever back references are not needed.</div>

<p><font size="+2"><b>A.9 Case Sensitivity<a name="regexcase"></a></b></font></p>
|
||
|
|
<div class="desc">As was already mentioned, Unreal makes all regexps case insensitive by default. The main reason for this is, there seem to be many more instances where you want case insensitive searching rather than sensitive, for example, if you block the text "www.test.com," you presumably want to block "WWW.TEST.COM" as well. However, there are instances where you may want case sensitivity, for example, matching for certain trojans. Because of this, a method is provided to dynamically turn case insensitivity on/off. To turn it off, simply use "(?-i)" and to turn it on, "(?i)". For example, "(?-i)[a-z](?i)[a-z]" will match a lowercase letter (case insensitivity is off) followed by either an uppercase or lowercase letter (case insensitivity is on). Additionally, rather than having to always remember to turn the flag back on when you are finished, you can also specify that the flag change should only apply to a subexpression, for example, "(?-i:[a-z])[a-z]" is equivilent to the previous regexp because the -i only applies to the given subexpression.
