In both cases the server will only send the PRIVMSG + to those who have a server or host matching the mask. The mask MUST + have at least 1 (one) "." in it and no wildcards following the last + ".". This requirement exists to prevent people sending messages to + "#*" or "$*", which would broadcast to all users. Wildcards are the + '*' and '?' characters.

The difference + between NOTICE and PRIVMSG is that automatic replies MUST NEVER be + sent in response to a NOTICE message. This rule applies to servers + too - they MUST NOT send any error reply back to the client on + receipt of a notice. The object of this rule is to avoid loops + between clients automatically sending something in response to + something it received. + + This command is available to services as well as users. + + This is typically used by services, and automatons (clients with + either an AI or other interactive program controlling their actions). + + See PRIVMSG for more details on replies and examples. + +3.4.1 Motd message + + Command: MOTD + Parameters: [ <target> ] + + The MOTD command is used to get the "Message Of The Day" of the given + server, or current server if <target> is omitted. + + Wildcards are allowed in the <target> parameter. + + Numeric Replies: + RPL_MOTDSTART RPL_MOTD + RPL_ENDOFMOTD ERR_NOMOTD + +3.4.2 Lusers message + + Command: LUSERS + Parameters: [ <mask> [ <target> ] ] + + The LUSERS command is used to get statistics about the size of the + IRC network.

The same + result can be achieved by using a <mask> of "0" or any wildcard which + will end up matching every visible user. + + The <mask> passed to WHO is matched against users' host, server, real + name and nickname if the channel <mask> cannot be found. + + If the "o" parameter is passed only operators are returned according + to the <mask> supplied. + + Numeric Replies: + + ERR_NOSUCHSERVER + RPL_WHOREPLY RPL_ENDOFWHO + + Examples: + + WHO *.fi ; Command to list all users who match + against "*.fi". + + WHO jto* o ; Command to list all users with a + match against "jto*" if they are an + operator. + +3.6.2 Whois query + + Command: WHOIS + Parameters: [ <target> ] <mask> *( "," <mask> ) + + This command is used to query information about particular user. + The server will answer this command with several numeric messages + indicating different statuses of each user which matches the mask (if + you are entitled to see them). If no wildcard is present in the + <mask>, any information about that nick which you are allowed to see + is presented. + + If the <target> parameter is specified, it sends the query to a + specific server. It is useful if you want to know how long the user + in question has been idle as only local server (i.e., the server the + user is directly connected to) knows that information, while + everything else is globally known. + + Wildcards are allowed in the <target> parameter. + + Numeric Replies: + + ERR_NOSUCHSERVER ERR_NONICKNAMEGIVEN + RPL_WHOISUSER RPL_WHOISCHANNELS + RPL_WHOISCHANNELS RPL_WHOISSERVER + RPL_AWAY RPL_WHOISOPERATOR + RPL_WHOISIDLE ERR_NOSUCHNICK + RPL_ENDOFWHOIS + + Examples: + + WHOIS wiz ; return available user information + about nick WiZ + + WHOIS eff.org trillian ; ask server eff.org for user + information about trillian + +3.6.3 Whowas + + Command: WHOWAS + Parameters: <nickname> *( "," <nickname> ) [ <count> [ <target> ] ] + + Whowas asks for information about a nickname which no longer exists. + This may either be due to a nickname change or the user leaving IRC. + In response to this query, the server searches through its nickname + history, looking for any nicks which are lexically the same (no wild + card matching here). The history is searched backward, returning the + most recent entry first. If there are multiple entries, up to + <count> replies will be returned (or all of them if no <count> + parameter is given). If a non-positive number is passed as being + <count>, then a full search is done. + + Wildcards are allowed in the <target> parameter. + + Numeric Replies: + + ERR_NONICKNAMEGIVEN ERR_WASNOSUCHNICK + RPL_WHOWASUSER RPL_WHOISSERVER + RPL_ENDOFWHOWAS + + Examples: + + WHOWAS Wiz ; return all information in the nick + history about nick "WiZ"; + + WHOWAS Mermaid 9 ; return at most, the 9 most recent + entries in the nick history for + "Mermaid"; + + WHOWAS Trillian 1 *.edu ; return the most recent history for + "Trillian" from the first server + found to match "*.edu". + +3.7.1 Kill message + + Command: KILL + Parameters: <nickname> <comment> + + The KILL command is used to cause a client-server connection to be + closed by the server which has the actual connection. Servers + generate KILL messages on nickname collisions. It MAY also be + available available to users who have the operator status. + + Clients which have automatic reconnect algorithms effectively make + this command useless since the disconnection is only brief. It does + however break the flow of data and can be used to stop large amounts + of 'flooding' from abusive users or accidents. Abusive users usually + don't care as they will reconnect promptly and resume their abusive + behaviour. To prevent this command from being abused, any user may + elect to receive KILL messages generated for others to keep an 'eye' + on would be trouble spots. + + In an arena where nicknames are REQUIRED to be globally unique at all + times, KILL messages are sent whenever 'duplicates' are detected + (that is an attempt to register two users with the same nickname) in + the hope that both of them will disappear and only 1 reappear. + + When a client is removed as the result of a KILL message, the server + SHOULD add the nickname to the list of unavailable nicknames in an + attempt to avoid clients to reuse this name immediately which is + usually the pattern of abusive behaviour often leading to useless + "KILL loops". See the "IRC Server Protocol" document [IRC-SERVER] + for more information on this procedure. + + The comment given MUST reflect the actual reason for the KILL. For + server-generated KILLs it usually is made up of details concerning + the origins of the two conflicting nicknames. For users it is left + up to them to provide an adequate reason to satisfy others who see + it. To prevent/discourage fake KILLs from being generated to hide + the identify of the KILLer, the comment also shows a 'kill-path' + which is updated by each server it passes through, each prepending + its name to the path. + + Numeric Replies: + + ERR_NOPRIVILEGES ERR_NEEDMOREPARAMS + ERR_NOSUCHNICK ERR_CANTKILLSERVER + + NOTE: + It is RECOMMENDED that only Operators be allowed to kill other users + with KILL command. This command has been the subject of many + controversies over the years, and along with the above + recommendation, it is also widely recognized that not even operators + should be allowed to kill users on remote servers. + +3.7.2 Ping message + + Command: PING + Parameters: <server1> [ <server2> ] + + The PING command is used to test the presence of an active client or + server at the other end of the connection. Servers send a PING + message at regular intervals if no other activity detected coming + from a connection. If a connection fails to respond to a PING + message within a set amount of time, that connection is closed. A + PING message MAY be sent even if the connection is active. + + When a PING message is received, the appropriate PONG message MUST be + sent as reply to <server1> (server which sent the PING message out) + as soon as possible. If the <server2> parameter is specified, it + represents the target of the ping, and the message gets forwarded + there. + + Numeric Replies: + + ERR_NOORIGIN ERR_NOSUCHSERVER + + Examples: + + PING tolsun.oulu.fi ; Command to send a PING message to + server + + PING WiZ tolsun.oulu.fi ; Command from WiZ to send a PING + message to server "tolsun.oulu.fi" + + PING :irc.funet.fi ; Ping message sent by server + "irc.funet.fi" + +3.7.3 Pong message + + Command: PONG + Parameters: <server> [ <server2> ] + + PONG message is a reply to ping message. If parameter <server2> is + given, this message MUST be forwarded to given target. The <server> + parameter is the name of the entity who has responded to PING message + and generated this message. + + Numeric Replies: + + ERR_NOORIGIN ERR_NOSUCHSERVER + + Example: + + PONG csd.bu.edu tolsun.oulu.fi ; PONG message from csd.bu.edu to + tolsun.oulu.fi + +3.7.4 Error + + Command: ERROR + Parameters: <error message> + + The ERROR command is for use by servers when reporting a serious or + fatal error to its peers. It may also be sent from one server to + another but MUST NOT be accepted from any normal unknown clients. + + Only an ERROR message SHOULD be used for reporting errors which occur + with a server-to-server link. An ERROR message is sent to the server + at the other end (which reports it to appropriate local users and + logs) and to appropriate local users and logs. It is not to be + passed onto any other servers by a server if it is received from a + server. + + The ERROR message is also used before terminating a client + connection. + + When a server sends a received ERROR message to its operators, the + message SHOULD be encapsulated inside a NOTICE message, indicating + that the client was not responsible for the error. + + Numerics: + + None. + + Examples: + + ERROR :Server *.fi already exists ; ERROR message to the other server + which caused this error. + + NOTICE WiZ :ERROR from csd.bu.edu -- Server *.fi already exists + ; Same ERROR message as above but + sent to user WiZ on the other server. + +4.1 Away + + Command: AWAY + Parameters: [ <text> ] + + With the AWAY command, clients can set an automatic reply string for + any PRIVMSG commands directed at them (not to a channel they are on). + The server sends an automatic reply to the client sending the PRIVMSG + command. The only replying server is the one to which the sending + client is connected to. + + The AWAY command is used either with one parameter, to set an AWAY + message, or with no parameters, to remove the AWAY message. + + Because of its high cost (memory and bandwidth wise), the AWAY + message SHOULD only be used for client-server communication. A + server MAY choose to silently ignore AWAY messages received from + other servers. To update the away status of a client across servers, + the user mode 'a' SHOULD be used instead. (See Section 3.1.5) + + Numeric Replies: + + RPL_UNAWAY RPL_NOWAWAY + + Example: + + AWAY :Gone to lunch. Back in 5 ; Command to set away message to + "Gone to lunch. Back in 5". + +4.2 Rehash message + + Command: REHASH + Parameters: None + + The rehash command is an administrative command which can be used by + an operator to force the server to re-read and process its + configuration file. + + Numeric Replies: + + RPL_REHASHING ERR_NOPRIVILEGES + + + Example: + + REHASH ; message from user with operator + status to server asking it to reread + its configuration file. + +4.3 Die message + + Command: DIE + Parameters: None + + An operator can use the DIE command to shutdown the server. This + message is optional since it may be viewed as a risk to allow + arbitrary people to connect to a server as an operator and execute + this command. + + The DIE command MUST always be fully processed by the server to which + the sending client is connected and MUST NOT be passed onto other + connected servers. + + Numeric Replies: + + ERR_NOPRIVILEGES + + Example: + + DIE ; no parameters required. + +4.4 Restart message + + Command: RESTART + Parameters: None + + An operator can use the restart command to force the server to + restart itself. This message is optional since it may be viewed as a + risk to allow arbitrary people to connect to a server as an operator + and execute this command, causing (at least) a disruption to service. + + The RESTART command MUST always be fully processed by the server to + which the sending client is connected and MUST NOT be passed onto + other connected servers. + + Numeric Replies: + + ERR_NOPRIVILEGES + + Example: + + RESTART ; no parameters required. + +4.5 Summon message + + Command: SUMMON + Parameters: <user> [ <target> [ <channel> ] ] + + The SUMMON command can be used to give users who are on a host + running an IRC server a message asking them to please join IRC. This + message is only sent if the target server (a) has SUMMON enabled, (b) + the user is logged in and (c) the server process can write to the + user's tty (or similar). + + If no <server> parameter is given it tries to summon <user> from the + server the client is connected to is assumed as the target. + + If summon is not enabled in a server, it MUST return the + ERR_SUMMONDISABLED numeric. + + Numeric Replies: + + ERR_NORECIPIENT ERR_FILEERROR + ERR_NOLOGIN ERR_NOSUCHSERVER + ERR_SUMMONDISABLED RPL_SUMMONING + + Examples: + + SUMMON jto ; summon user jto on the server's + host + + SUMMON jto tolsun.oulu.fi ; summon user jto on the host which a + server named "tolsun.oulu.fi" is + running. + +4.6 Users + + Command: USERS + Parameters: [ <target> ] + + The USERS command returns a list of users logged into the server in a + format similar to the UNIX commands who(1), rusers(1) and finger(1). + If disabled, the correct numeric MUST be returned to indicate this. + + Because of the security implications of such a command, it SHOULD be + disabled by default in server implementations. Enabling it SHOULD + require recompiling the server or some equivalent change rather than + simply toggling an option and restarting the server. The procedure + to enable this command SHOULD also include suitable large comments. + + Numeric Replies: + + ERR_NOSUCHSERVER ERR_FILEERROR + RPL_USERSSTART RPL_USERS + RPL_NOUSERS RPL_ENDOFUSERS + ERR_USERSDISABLED + + Disabled Reply: + + ERR_USERSDISABLED + + Example: + + USERS eff.org ; request a list of users logged in + on server eff.org + +4.7 Operwall message + + Command: WALLOPS + Parameters: <Text to be sent> + + The WALLOPS command is used to send a message to all currently + connected users who have set the 'w' user mode for themselves. (See + Section 3.1.5 "User modes"). + + After implementing WALLOPS as a user command it was found that it was + often and commonly abused as a means of sending a message to a lot of + people. Due to this, it is RECOMMENDED that the implementation of + WALLOPS allows and recognizes only servers as the originators of + WALLOPS. + + Numeric Replies: + + ERR_NEEDMOREPARAMS + + Example: + + :csd.bu.edu WALLOPS :Connect '*.uiuc.edu 6667' from Joshua ; WALLOPS + message from csd.bu.edu announcing a + CONNECT message it received from + Joshua and acted upon. + +4.8 Userhost message + + Command: USERHOST + Parameters: <nickname> *( SPACE <nickname> ) + + The USERHOST command takes a list of up to 5 nicknames, each + separated by a space character and returns a list of information + about each nickname that it found.

ISON only takes one (1) type of parameter: a space-separated + list of nicks. For each nickname in the list that is present, the + server adds that to its reply string. Thus the reply string may + return empty (none of the given nicks are present), an exact copy of + the parameter string (all of them present) or any other subset of the + set of nicks given in the parameter. The only limit on the number of + nicks that may be checked is that the combined length MUST NOT be too + large as to cause the server to chop it off so it fits in 512 + characters. + + ISON is only processed by the server local to the client sending the + command and thus not passed onto other servers for further + processing. + + Numeric Replies: + + RPL_ISON ERR_NEEDMOREPARAMS + + Example: + + ISON phone trillian WiZ jarlek Avalon Angel Monstah syrk + ; Sample ISON request for 7 nicks. |
