   1 Undernet server features.
   2 -------------------------
   3
   4 This document is supposed to list the features that undernet supports and
   5 provides to clients, and which version of ircu this was added.  Additional
   6 numeric replies should be added here too.
   7
   8 Extended Who information: (WHOX)
   9  Version: unknown, but at least 2.10.07+
  10
  11  This is described in the file 'readme.who'
  12
  13 USERIP:
  14  Version: unknown, but at least 2.10.07+
  15
  16  This works the same as userhost, but returns the IP instead, useful for
  17  setting a ban on someones IP address instead of their nick.
  18  usage:
  19   USERIP nick[,nick...]
  20  returns:
  21   RPL_USERIP (307)
  22   :server.name 307 target nick[*]=[+|-]user@host...
  23
  24 RPL_ISUPPORT:
  25  version: 2.10.08+
  26
  27  This sends a numeric during client signon that lists various features that
  28  ircu supports.  This allows client and script writers to know what features
  29  they can use, and various parameters about the irc server.  The numeric
  30  used is '005' to try and maintain some semblance of compatibility with
  31  dalnet which has a similar feature.  The 005 numeric may be split across
  32  multiple lines if the length exceeds 512 characters.
  33
  34  The format is:
  35   :servername 005 target feature1 feature2... :are supported by this server.
  36   :servername 005 target feature200... :are supported by this server.
  37
  38  features are either a word describing the feature eg: 'SILENCE', or a word
  39  describing the feature and an equals and a list of parameters.
  40  eg: SILENCE=15 (says that we support silence, and we support up to 15 of
  41  them per user), or FOO=12,3 (says we support FOO with parameters 12 and 3)
  42  for example 2.10.08 lists:
  43
  44  :test.undernet.org 005 test SILENCE=15 WHOX WALLCHOPS USERIP CPRIVMSG
  45    CNOTICE MODES=6 MAXCHANNELS=10 MAXBANS=30 NICKLEN=9 TOPICLEN=160
  46    KICKLEN=160
  47
  48  NOTE: Versions prior to 2.10.08+ use numeric 005 as part of 'MAP', so
  49  005 should be /not/ be used after the server registration has occured.
  50  (ie: after END_OF_MOTD has arrived).
  51
  52 MAP:
  53  Version: unknown, but since 2.9.30 at least, updated in 2.10.08
  54
  55  /map shows the servers as the server percieves them, who's connected
  56  to who in a pretty display.  In version 2.10.08 it also lists the
  57  amount time time it takes a message to get /from/ a server to the local
  58  server - this measures the one way lag only, in 2.10.08 it also lists
  59  the number of clients that are currently on that server.
  60  The lag estimation is very approximate and depends on people changing nick
  61  and joining channels, so the less clients on a server the less reliable the
  62  lag estimation is.
  63
  64  Map prior to 2.10.08 uses:
  65   RPL_MAP     005
  66   RPL_MAPMORE 006
  67   RPL_MAPEND  007
  68  Map changed in 2.10.08 to allow for ISUPPORT on numeric 005, the new
  69   numerics are:
  70   RPL_MAP     015
  71   RPL_MAPMORE 016
  72   RPL_MAPEND  017
  73
  74 WALLCHOPS:
  75  Version: unknown, but since 2.10.07
  76
  77  WALLCHOPS sends a message to all channel operators (@)'s on a channel.
  78  It does /not/ require you to be op'd (@'d) to do so.  This is a feature.
  79
  80  syntax:
  81   WALLCHOPS #channel :message
  82  or:
  83   NOTICE @#channel :message
  84
  85  this sends:
  86   :user NOTICE @#channel :message
  87  to clients that are @'d on the channel.
  88
  89 CPRIVMSG/CNOTICE:
  90  Version: unknown, but since 2.10.07
  91
  92  CPRIVMSG/CNOTICE are a way around target limiting in recent undernet
  93  servers.  Undernet servers prevent you from sending messages to too many
  94  people at once in an attempt to help cut down the amount of spam that
  95  occurs on the network.  Because there are several situations where you want
  96  to send messages to lots of people that are on the same channel as you
  97  (autogreet's and gamebots for example) an 'escape' was made in the form
  98  of CPRIVMSG/CNOTICE.  These allow you to send a privmsg/notice to a person
  99  on a common channel if you are op'd (@'d) without incuring a target
 100  penalty.  If you see 'Target changed too fast' messages, you should
 101  probably be using these commands.
 102
 103  Syntax:
 104   CPRIVMSG #channel nick :Message
 105   CNOTICE #channel nick :Message
 106
 107  Results are the same as for 'PRIVMSG' and 'NOTICE' respectively.
 108
 109 SILENCE:
 110  Version: unknown, 2.9.32 at least.
 111
 112  Silence is a server side ignore.  You can /silence +hostmask or
 113  /silence +nick, to add someone to your silence list, or use /silence
 114  -hostmask to remove it.  /silence will list your 'silence list'.
 115  you can /silence nick, to see someone elses silence list (useful for
 116  helping someone).  Silence is preferably used as a last resort as it
 117  tends to use server CPU time.  Undernet typically only allows 15 silences
 118  per user.  in 2.10.08+ this information is available in the RPL_ISUPPORT
 119  line.
 120
 121  Syntax:
 122   SILENCE +hostmask
 123   SILENCE +nick
 124   SILENCE -hostmask
 125   SILENCE -nick
 126   SILENCE nick
 127
 128  reply:
 129   RPL_SILELIST      217
 130   RPL_ENDOFSILELIST 218
 131
 132 User modes:
 133  Version: various
 134
 135  Undernet supports these additional user modes:
 136   +d: Deaf & Dumb.  This user will not get any channel traffic.  Used for
 137       bots.
 138   +k: This user cannot be kicked, deop'd or /kill'd.  This usermode may only
 139       be set by a server, it may not be set by a user.  This is used by
 140       undernet service bots (X/W/UWorld etc)
 141   +g: List channel HACK:'s
 142   +s: Server messages - takes a parameter of which masks to send, see
 143       'snomask.html' for more details. (2.10.0+)
 144
 145 LIST:
 146  Version: Unknown
 147
 148  List now takes various parameters to allow you to quickly and efficiently
 149  find interesting channels.  These are:
 150
 151  >n or <n   show channels with less than or greater than 'n' users
 152             respectively
 153  C>n or C<n show channels that have existed for less than or greater than
 154             'n' minutes.
 155  T>n or C<n show channels that have had their topic changed in less than or
 156             greater than 'n' minutes.
 157
 158  Additional Numerics:
 159   RPL_LISTHELP 334
 160
 161 Additional Topic Numerics:
 162  Version: Since the dawn of time.
 163
 164  Topic also lists who set it and when they set it.
 165
 166  Additional Numerics:
 167   RPL_TOPICWHOTIME 333
 168
 169  Straight after the topic:
 170   :server.name 333 #channel Isomer 923423442
 171  where the number is seconds past 00:00 1970-01-01 that the topic was set.
 172
 173
 174 INVITE list:
 175  Version: 2.10.08+
 176
 177  /invite without any parameters lists which channels you have an outstanding
 178  invite to (ie: an invite to a channel which you haven't joined)
 179
 180  Additional Numerics:
 181   RPL_INVITELIST      346
 182   RPL_ENDOFINVITELIST 347
 183
 184 NICK change:
 185  Version: Since the dawn of time.
 186
 187  Undernet prevents you from changing nick on a channel while your banned.
 188  Undernet prevents you changing nicks more than once per 30 seconds, you
 189  get one 'free' nick change if you haven't changed nick recently.
 190
 191  Additional Numerics:
 192   RPL_BANNICKCHANGE 347
 193   RPL_NICKTOOFAST   349
 194
 195 Target limiting:
 196  Version: Recent 2.10.07ish at least.
 197
 198  Undernet prevents you from changing 20 targets per 2 minutes.  A target
 199  is a 'Nick' or 'channel'.  This is to prevent spam.  If you message more
 200  than 20 people or join more than 20 channels in two minutes then you'll
 201  start getting 'Target change too fast' and will have to wait before you
 202  can start talking.  See CPRIVMSG/CNOTICE above for information on how to
 203  avoid this.
 204
 205  Additional Numerics:
 206   ERR_TARGETTOOFAST 349
