Undernet server features. ------------------------- This document is supposed to list the features that undernet supports and provides to clients, and which version of ircu this was added. Additional numeric replies should be added here too. Extended Who information: (WHOX) Version: unknown, but at least 2.10.07+ This is described in the file 'readme.who' USERIP: Version: unknown, but at least 2.10.07+ This works the same as userhost, but returns the IP instead, useful for setting a ban on someones IP address instead of their nick. usage: USERIP nick[,nick...] returns: RPL_USERIP (307) :server.name 307 target nick[*]=[+|-]user@host... RPL_ISUPPORT: version: 2.10.08+ This sends a numeric during client signon that lists various features that ircu supports. This allows client and script writers to know what features they can use, and various parameters about the irc server. The numeric used is '005' to try and maintain some semblance of compatibility with dalnet which has a similar feature. The 005 numeric may be split across multiple lines if the length exceeds 512 characters. The format is: :servername 005 target feature1 feature2... :are supported by this server. :servername 005 target feature200... :are supported by this server. features are either a word describing the feature eg: 'SILENCE', or a word describing the feature and an equals and a list of parameters. eg: SILENCE=15 (says that we support silence, and we support up to 15 of them per user), or FOO=12,3 (says we support FOO with parameters 12 and 3) for example 2.10.08 lists: :test.undernet.org 005 test SILENCE=15 WHOX WALLCHOPS USERIP CPRIVMSG CNOTICE MODES=6 MAXCHANNELS=10 MAXBANS=30 NICKLEN=9 TOPICLEN=160 KICKLEN=160 NOTE: Versions prior to 2.10.08+ use numeric 005 as part of 'MAP', so 005 should be /not/ be used after the server registration has occured. (ie: after END_OF_MOTD has arrived). MAP: Version: unknown, but since 2.9.30 at least, updated in 2.10.08 /map shows the servers as the server percieves them, who's connected to who in a pretty display. In version 2.10.08 it also lists the amount time time it takes a message to get /from/ a server to the local server - this measures the one way lag only, in 2.10.08 it also lists the number of clients that are currently on that server. The lag estimation is very approximate and depends on people changing nick and joining channels, so the less clients on a server the less reliable the lag estimation is. Map prior to 2.10.08 uses: RPL_MAP 005 RPL_MAPMORE 006 RPL_MAPEND 007 Map changed in 2.10.08 to allow for ISUPPORT on numeric 005, the new numerics are: RPL_MAP 015 RPL_MAPMORE 016 RPL_MAPEND 017 WALLCHOPS: Version: unknown, but since 2.10.07 WALLCHOPS sends a message to all channel operators (@)'s on a channel. It does /not/ require you to be op'd (@'d) to do so. This is a feature. syntax: WALLCHOPS #channel :message or: NOTICE @#channel :message this sends: :user NOTICE @#channel :message to clients that are @'d on the channel. CPRIVMSG/CNOTICE: Version: unknown, but since 2.10.07 CPRIVMSG/CNOTICE are a way around target limiting in recent undernet servers. Undernet servers prevent you from sending messages to too many people at once in an attempt to help cut down the amount of spam that occurs on the network. Because there are several situations where you want to send messages to lots of people that are on the same channel as you (autogreet's and gamebots for example) an 'escape' was made in the form of CPRIVMSG/CNOTICE. These allow you to send a privmsg/notice to a person on a common channel if you are op'd (@'d) without incuring a target penalty. If you see 'Target changed too fast' messages, you should probably be using these commands. Syntax: CPRIVMSG #channel nick :Message CNOTICE #channel nick :Message Results are the same as for 'PRIVMSG' and 'NOTICE' respectively. SILENCE: Version: unknown, 2.9.32 at least. Silence is a server side ignore. You can /silence +hostmask or /silence +nick, to add someone to your silence list, or use /silence -hostmask to remove it. /silence will list your 'silence list'. you can /silence nick, to see someone elses silence list (useful for helping someone). Silence is preferably used as a last resort as it tends to use server CPU time. Undernet typically only allows 15 silences per user. in 2.10.08+ this information is available in the RPL_ISUPPORT line. Syntax: SILENCE +hostmask SILENCE +nick SILENCE -hostmask SILENCE -nick SILENCE nick reply: RPL_SILELIST 217 RPL_ENDOFSILELIST 218 User modes: Version: various Undernet supports these additional user modes: +d: Deaf & Dumb. This user will not get any channel traffic. Used for bots. +k: This user cannot be kicked, deop'd or /kill'd. This usermode may only be set by a server, it may not be set by a user. This is used by undernet service bots (X/W/UWorld etc) +g: List channel HACK:'s +s: Server messages - takes a parameter of which masks to send, see 'snomask.html' for more details. (2.10.0+) LIST: Version: Unknown List now takes various parameters to allow you to quickly and efficiently find interesting channels. These are: >n or n or Cn or C
