ACCEPT
ACCEPT nick, -nick, …
Adds or removes users from your accept list for umode +g and +R. Users are automatically removed when they quit, split or change nick.
ACCEPT *
Lists all users on your accept list.
Support of this command is indicated by the CALLERID token in RPL_ISUPPORT (005); the optional
parameter indicates the letter of the “only allow accept users to send private messages” umode, otherwise +g. In charybdis this is always +g.

CNOTICE
CNOTICE nick channel :text
Providing you are opped (+o) or voiced (+v) in channel, and nick is a member of channel,
CNOTICE generates a NOTICE towards nick.
CNOTICE bypasses any anti-spam measures in place. If you get “Targets changing too fast, message dropped”, you should probably use this command, for example sending a notice to every user joining a certain channel.
Support of this command is indicated by the CNOTICE token in RPL_ISUPPORT (005).

CPRIVMSG
CPRIVMSG nick channel :text
Providing you are opped (+o) or voiced (+v) in channel, and nick is a member of channel,
CPRIVMSG generates a PRIVMSG towards nick.
CPRIVMSG bypasses any anti-spam measures in place. If you get “Targets changing too fast, message dropped”, you should probably use this command.
Support of this command is indicated by the CPRIVMSG token in RPL_ISUPPORT (005).

HELP
HELP [topic]
Displays help information. topic can be INDEX, CREDITS, UMODE, CMODE, SNOMASK or a command name.
There are separate help files for users and opers. Opers can use UHELP to query the user help files.

KNOCK
KNOCK channel
Requests an invite to the given channel. The channel must be locked somehow (+ikl), must not be +p and you may not be banned or quieted. Also, this command is rate limited. If successful, all channel operators will receive a 710 numeric. The recipient field of this numeric is the channel.
Support of this command is indicated by the KNOCK token in RPL_ISUPPORT (005).

MONITOR
Server side notify list. This list contains nicks. When a user connects, quits with a listed nick or changes to or from a listed nick, you will receive a 730 numeric if the nick went online and a 731 numeric if the nick went offline.
Support of this command is indicated by the MONITOR token in RPL_ISUPPORT (005); the parameter indicates the maximum number of nicknames you may have in your monitor list. You may only use this command once per second.
More details can be found in doc/monitor.txt in the source distribution.
MONITOR + nick, …

IRCWorld is running blacklist detector to prevent clients from misconfigured or infected hosts from connecting to our network.

The machine on your host has an insecure proxy, or could possibly be infected with a virus or trojan or it is/was used for spamming, denial of service attack or other kind of abuse.

You should check all of the running services on the machine and make sure that they are either properly firewalled or have working access control lists.

In case of spamming or denial of service attacks and other kind of abuse, you should contact your internet service provider to settle this matter.

If everything checks ok, and you are running any Windows operating system, verify that you are using an antivirus program to make sure you have not been backdoored.

More information about open proxies is available under "Open Proxy".

For more information you can also e-mail staff|at|ircworld.org

If you have been K:lined (banned) from IRCWorld IRC Network and the link told you to go here then please be advised that you are possibly using an open proxy server. There are several different types of open proxy, but they all take the form of a piece of software that allows other computers to “bounce” through it to access the Internet. This can be legitimately useful in many situations, but the one you are using is configured incorrectly and allows anyone to use it. Open proxies are not permitted, and hosts using open proxies will be banned from all servers.

If you have been on IRC for any length of time, you have probably seen an attack using open proxies at least once. Hundreds of clients will enter a channel, often with random nick names, and start sending large amounts of coloured channel and CTCP messages. Commonly they will leave and join the channel rapidly in order to cause more disruption.

Without completely locking up the channel, there is no effective way to stop the flood. Even if the channel is locked up, the floods of text can be sent to individual users and will usually be enough to disconnect them. Most of these types of attacks use open proxies because open proxies are relatively easy to come by. Lists of them are readily available over the Internet. This is why IRCWorld IRC Network does not permit such hosts access to the network. If you have to use a proxy, it should be configured correctly.

If you administer your network then read on, else point the administrator at this page. Please note we cannot help you configure your specific proxy software – just give some general guidelines, usually the makers website will have more helpful instructions then ones we can give you.

Nowadays we have several types of proxies, you need to find out what sort of proxy has been detected on your host then you can follow the relevant instructions below. In nearly all cases it is a matter of changing the configuration to limit the proxy to particular IP addresses. If you aren’t sure what sort of proxy you are running then try the cyberabuse scanner which will scan your IP address for open proxies of various types.

HTTP Connect
A misconfigured HTTP proxy designed to allow SSL access via the connect command can be used to make TCP connections to any host. In some cases the default configuration might allow this type of access.

HTTP Post
These types of proxy do not allow full TCP connections like the HTTP Connect type but they are more widespread (some well known ISPs even run open proxies of this type). Many HTTP proxies or web caches can be abused in this way if they do not have the correct permissions (or ACLs) in place.

WinGate
This is a specifc package that is designed to allow telnet access via a gateway, it is just a case of setting the access controls correctly to only allow access to the people who need to use the service.

SOCKS
SOCKS allows access behind firewalls from IP addresses which are not accessible on the public internet, again this is a case of limiting its usage to only the IP addresses which require access to the service.

Cisco
These are cisco routers with an insecure default password which allows telnet access to be gained through the router. You will need to change the password on the router to something more secure.

Session Limit is to prevent cloning on IRCWorld IRC Network. When you see a “Excessive clones” (kill) message, it means that more than 3 connections from (your) one host are being made to the IRCWorld IRC Network servers. Since our network does’nt allow cloning, you are being disconnected if you make more than 3 simultaneous connections from your unique host.
If you are using a NAT firewall or other type of IP masquerading or Internet connection sharing then the Session Limit exemption can be made. Session limit exemption are made by the IRCWorld IRC Network Staff. Contact an oper or e-mail staff|at|ircworld.org to request a Session limit exemption. Please be advised that a good reason is required to get an Session limit exemption. For an example – The Session limit exemption cannot be granted to users with dynamic IP addresses. Sorry.

Warning! Please do not hammer if you get an “Session limit exceeded” message or you will be automatically banned from the network!

Extended bans (ban conditionals) allow different checks than the usual nick!user@host or nick!user@ip match to determine whether someone should be banned, quieted, exempted or invited.

Extended bans are of the form $[~][:]. The is one character (case insensitive) and determines the type of match. Most types allow or require an extra field . If the tilde (~) is present, the result of the comparison will be negated, unless the ban is invalid in which case it will never match

Note: Extended ban types also work with +e (ban exemption), +q (quiet ban), and +I (invite exception). Check channel modes for more information.

Syntax: /mode [+/-]b/e/q/I $[~][:]

$a – logged in users
Syntax: /mode [+/-]b/e/q/I $a:
Example: /mode #channel +b $a:username
Matches users logged in with a username matching the mask (* and ? wildcards).

The above example will ban shadow when he is identified to his nick, regardless of the nickname he is using at the time.

$c – channel
Syntax: /mode [+/-]b/e/q/I $c:
Example: /mode #channel +b $c:#channel2
Matches users who are on the given channel; this is only valid if the channel exists and is not +s or +p. (The ops of the channel the ban is on cannot necessarily see whether the user is in the target channel, so it should not influence whether they can join either.)

The above example will prevent users in #channel2 from joining the #channel.

$j – shared banlists
Syntax: /mode [+/-]b/e/q/I $j:
Example: /mode #channel +b $j:#channel
Bans anyone who is also banned in the specified channel. Also works for ban exemptions, quiet bans, and invex’s.

The above example will ban anyone in #channel who is also banned from #rmxp.

$o – IRC Operators
Syntax: /mode [+/-]b/e/q/I $o
Example: /mode #staff +I $o
Matches opers (most useful with +I).

The example above, with the +i mode on, will only allow IRC Operators to join.

$r – gecos (realname)
Syntax: /mode [+/-]b/q $r:
Example: /mode #channel +b $r:Real?name
Matches users with a realname (gecos) matching the mask (* and ? wildcards); this can only be used with +b and +q.

The above example bans users with the gecos “Real name”.

$s – server
Syntax: /mode [+/-]b/q $s:
Example: /mode #channel +b $s:us.ircworld.org
Matches users connected to a server matching the mask (* and ? wildcards); this can only be used with +b and +q.

The above example bans users, who connect to the server us.ircworld.org.

$x – extended
Syntax: /mode [x/-]b/e/q/I $x:!@#
Example: /mode #channel +b $x:nick!ident@staff.ircworld.org#Real?name
Extended bans match an entire hostmask, including the user’s “gecos” (real name). Wildcards are allowed.

The above example bans the nickname “Nick”, with the ident “ident”, the hostmask “staff.ircworld.org”, and the gecos “Real?name”.

With a ~ (Tilde)
A tilde will cause the result of the comparison will be negated.

Example: /mode #channel +b $~o
Will ban anyone who isn’t an IRC Operator.

Example: /mode #channel +b $~c:#channel will ban anyone who isn’t also in #channel.
