ngIRCd - Next Generation IRC Server http://ngircd.barton.de/ (c)2001-2019 Alexander Barton and Contributors. ngIRCd is free software and published under the terms of the GNU General Public License. -- Commands.txt -- This file lists all commands available on ngIRCd. It is written in a format that is human readable as well as machine parseable and therefore can be used as "help text file" of the daemon. In short, the daemon reads this file on startup and parses it as following when an user issues a "HELP " command: 1. Search the file for a line "- ", 2. Output all subsequent lines that start with a TAB (ASCII 9) character to the client using NOTICE commands, treat lines containing a single "." after the TAB as empty lines. 3. Break at the first line not starting with a TAB character. This format allows to have information to each command stored in this file which will not be sent to an IRC user requesting help which enables us to have additional annotations stored here which further describe the origin, implementation details, or limits of the specific command which are not relevant to an end-user but administrators and developers. A special "Intro" block is returned to the user when the HELP command is used without a command name: - Intro This is ngIRCd, a server software for Internet Relay Chat (IRC) networks. You can find more information about ngIRCd on its homepage: . Use "HELP COMMANDS" to get a list of all available commands and "HELP " to get help for a specific IRC command, for example "HELP quit" or "HELP privmsg". Connection Handling Commands ~~~~~~~~~~~~~~~~~~~~~~~~~~~~ - CAP CAP LS CAP LIST CAP REQ CAP ACK CAP NAK CAP CLEAR CAP END . List, request, and clear "IRC Capabilities". . Using this command, an IRC client can request additional "IRC capabilities" during login or later on, which influences the communication between server and client. Normally, these commands aren't directly used by humans, but automatically by their client software. And please note that issuing such commands manually can irritate the client software used, because of the "non-standard" behavior of the server! . - CAP LS: list all available capabilities. - CAP LIST: list active capabilities of this connection. - CAP REQ: Request particular capabilities. - CAP ACK: Acknowledge a set of capabilities to be enabled/disabled. - CAP NAK: Reject a set of capabilities. - CAP CLEAR: Clear all set capabilities. - CAP END: Indicate end of capability negotiation during login, ignored in an fully registered session. Please note that the must be given in a single parameter but whitespace separated, therefore a command could look like this: "CAP REQ :capability1 capability2 capability3" for example. References: - - - doc/Capabilities.txt - CHARCONV CHARCONV . Set client character set encoding to . . After receiving such a command, the server translates all message data received from the client using the set to the server encoding (UTF-8), and all message data which is to be sent to the client from the server encoding (UTF-8) to . . This enables older clients and clients using "strange" character sets to transparently participate in channels and direct messages to clients using UTF-8, which should be the default today. References: - IRC+, - IRC+, doc/Protocol.txt - NICK NICK NICK [] NICK . Set or change the of a client (first form) and register remote clients (second and third form; servers only). References: - RFC 1459, 4.1.2 "Nick message" (old client and server protocol) - RFC 2812, 3.1.2 "Nick message" (client protocol) - RFC 2813, 4.1.3 "Nick" (server protocol) - PASS PASS PASS [] . Set a connection . This command must be the first command sent to the server, even before the NICK/USER or SERVER commands. . The first form is used by user sessions or (old) RFC 1459 servers, the second form is used by RFC 2812 or IRC+ compliant servers and enables the server to indicate its version and supported protocol features. References: - RFC 1459, 4.1.1 "Password message" (old client and server protocol) - RFC 2812, 3.1.1 "Password message" (client protocol) - RFC 2813, 4.1.1 "Password message" (server protocol) - IRC+, - IRC+, doc/Protocol.txt - PING PING [] . Tests the presence of a connection to a client or server. . If no has been given, the local server is used. User clients can only use other servers as , no user clients. . A PING message results in a PONG reply containing the , which can be arbitrary text. Please note: The RFCs state that the parameter is used to specify the origin of the PING command when forwarded in the network, but this is not the case: the sender is specified using the prefix as usual, and the parameter is used to identify the PONG reply in practice. References: - RFC 2812, 3.7.2 "Ping message" - PONG PONG [] . Reply to a "PING" command, indicate that the connection is alive. . The is the arbitrary text received in the "PING" command and can be used to identify the correct PONG sent as answer. . When the "PONG" command is received from a user session, the parameter is ignored; otherwise the PONG is forwarded to this client. References: - RFC 2812, 3.7.3 "Pong message" - QUIT QUIT [] . Terminate a user session. . When received from a user, the server acknowledges this by sending an "ERROR" message back to the client and terminates the connection. . When a has been given, it is sent to all the channels that the client is a member of when leaving. References: - RFC 2812, 3.1.7 "Quit" - RFC 2813, 4.1.5 "Quit" - USER USER . Register (and authenticate) a new user session with a short and a human-readable . . The parameter is only used when received by an other server and ignored otherwise; and the parameter is always ignored. But both parameters are required on each invocation by the protocol and can be set to arbitrary characters/text when not used. . If contains an "@" character, the full is used for authentication, but only the first part up to this character is set as "user name" for this session. References: - RFC 2812, 3.1.3 "User message" - WEBIRC WEBIRC . Allow Web-to-IRC gateway software (for example) to set the correct user name and host name of users instead of their own. . It must be the very first command sent to the server, even before USER and NICK commands! . The must be set in the server configuration file to prevent unauthorized clients to fake their identity; it is an arbitrary string. References: - IRC+, - IRC+, doc/Protocol.txt General Commands ~~~~~~~~~~~~~~~~ - AWAY AWAY [] . Provides the server with a message to automatically send in reply to a PRIVMSG directed at the user, but not to a channel they are on. . If is omitted, the away status is removed. References: - RFC 2812, 4.1 "Away" - HELP HELP [] . Show help information for a specific IRC . The name is case-insensitive. . Use the command "HELP Commands" to get a list of all available commands. The HELP command isn't specified by any RFC but implemented by most daemons. If no help text could be read in, ngIRCd outputs a list of all implemented commands when receiving a plain "HELP" command as well as on "HELP Commands". ngIRCd replies using "NOTICE" commands like ircd 2.10/2.11; other implementations are using numerics 704, 705, and 706. - MODE MODE [{+|-}[] [{+|-}[] [...]]] MODE [{+|-}[] [ [ [...]]] [{+|-}[] [ [ [...]]] [...]]] . Set and get user and channel modes. . When no mode parameters are given, the currently set user or channel modes are returned. Otherwise the modes are adjusted accordingly and the changes will be reported back to the client. . All user and channel "modes" are indicated by single case-sensitive characters. . Please note that a user can only get and set his own modes, and not all user "levels" are allowed to change all channel modes ... . The mode parameters can become quite complex, especially when dealing with channel modes that require additional arguments: . {+|-} -- set or unset one or more modes. + - -- set some modes and unset others. + -- set (at least) two modes with arguments. . Some examples: . MODE nick +i -- set user to "invisible". MODE #chan +tn -- set "topic lock" and "no external messages". MODE #chan -t +l 50 -- remove "topic lock", set "user limit" to 50. MODE #chan +ov nick1 nick2 -- set "channel op" and "voice" mode to nick1 and nick2 in channel #chan. . A complete list of all modes supported by ngIRCd can be found online here: . References: - RFC 2811, 4. "Channel Modes" - RFC 2812, 3.1.5 "User mode message" - RFC 2812, 3.2.3 "Channel mode message" - - doc/Modes.txt - NOTICE NOTICE [,[,...]] . Send a to a given , which can be a user or a channel, but DON'T report any error. . The "NOTICE" command exactly behaves like the "PRIVMSG" command, but doesn't report any errors it encounters (like an unknown ). Please see the help text of the "PRIVMSG" command for a detailed description of the parameters! References: - RFC 2812, 2.3.1 "Message format in Augmented BNF" - RFC 2812, 3.3 "Sending messages" - RFC 2812, 3.3.2 "Notice" - PRIVMSG PRIVMSG [,[,...]] . Send a to a given , which can be a user or a channel, and report all errors. . The must follow one of these syntax variants: . - - - [%]@ - % - !@ . If the is a user, a private message is sent directly to this user; if it resolves to a channel name, a public message is sent to all the members of that channel. . In addition, IRC Ops can use these two forms to specify the : . - # - $ . The can contain the wildcard characters "*" and "?", but must contain at least one dot (".") and no wildcard after the last one. Then, the is sent to all users matching this . . All warnings and errors are reported back to the initiator using numeric status codes, which is the only difference to the "NOTICE" command, which doesn't report back any errors or warnings at all. . Please note that clients often use "MSG" as an alias to PRIVMSG, and a command "QUERY []" to initiate private chats. Both are command extensions of the client and never sent to the server. References: - RFC 2812, 2.3.1 "Message format in Augmented BNF" - RFC 2812, 3.3 "Sending messages" - RFC 2812, 3.3.1 "Private messages" Status and Informational Commands ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ - ADMIN ADMIN [] . Show administrative information about an IRC server in the network. . can be a server name, the nickname of a client connected to a specific server, or a mask matching a server name in the network.

The server replies with a list only containing nicknames actually connected to a server in the network. If no nicknames of the given list are online, an empty list is returned to the client requesting the information. Please note that "all" IRC daemons even parse separate nicknames in a single parameter (like ":nick1 nick2"), and therefore ngIRCd implements this behavior, too. References: - RFC 2812, 4.9 "Ison message" - LINKS LINKS [[] ] . List all servers currently registered in the network matching , or all servers if has been omitted, as seen by the server specified by or the local server when is omitted. . can be a server name, the nickname of a client connected to a specific server, or a mask matching a server name in the network.

The server of the current connection is used when is omitted. References - RFC 2812, 3.4.6 "Time message" - TRACE TRACE [] . Find the route to a specific server and send information about its peers. Each server that processes this command reports back to the sender about it: the replies from pass-through servers form a chain which shows the route to the destination. . can be a server name, the nickname of a client connected to a specific server, or a mask matching a server name in the network. The server of the current connection is used when is omitted. References: - RFC 2812, 3.4.8 "Trace message" - USERHOST USERHOST [ [...]] . Show flags and the hostmasks (@) of the s, separated by spaces. The following flags are used: . - "-" The client is "away" (the mode "+a" is set on this client). - "+" Client seems to be available, at least it isn't marked "away". - "*" The client is an IRC operator (the mode "+o" is set). References: - RFC 2812, 4.8 "Userhost message" - VERSION VERSION [] . Show version information about a particular IRC server in the network. . can be a server name, the nickname of a client connected to a specific server, or a mask matching a server name in the network. The server of the current connection is used when is omitted. . Please note: in normal operation, the version number ends in a dot (".", for example "ngIRCd-20.1."). If it ends in ".1" (for example "ngIRCd-20.1.1", same version than before!), the server is running in debug-mode; and if it ends in ".2", the "network sniffer" is active! Keep your privacy in mind ... References: - RFC 2812, 3.4.3 "Version message" - WHO WHO [ ["o"]] . Show a list of users who match the , or all visible users when the has been omitted. (Special case: the "0" is equivalent to "*") . If the flag "o" is given, the server will only return information about IRC Operators.

References: - RFC 2812, 3.2.2 "Part message" - TOPIC TOPIC [] . Change or view the topic of a channel. . The topic for channel is returned if there is no given. If the parameter is present, the topic for that channel will be changed, if this action is allowed for the user requesting it. If the parameter is an empty string, the topic for that channel will be removed. References: - RFC 2812, 3.2.4 "Topic message" Administrative Commands ~~~~~~~~~~~~~~~~~~~~~~~ - CONNECT CONNECT [ [ [ ]]] .

References: - RFC 2812, 4.3 "Die message" - DISCONNECT DISCONNECT . Disconnect and disable a locally linked server. . To use this command, the user must be an IRC Operator. References: - This command is not specified in the IRC RFCs, it is an extension of ngIRCd. - GLINE GLINE [ :] . This command provides timed G-Lines (network-wide bans). . If a client matches a G-Line, it cannot connect to any server on the IRC network for seconds. When is 0, it make the G-Line permanent. . If no and no is given, the G-Line is removed. . To use this command, the user must be an IRC Operator. . "STATS g" can be used to list all currently active G-Lines. References: - This command is not specified in the IRC RFCs, it is an extension of ngIRCd. - KILL KILL . Forcibly remove all users with a given from the IRC network and display the given to them. . This command is used internally between servers, too, for example to disconnect duplicate 's after a "net split". . To use this command, the user must be an IRC Operator. References: - RFC 2812, 3.7.1 "Kill message" - KLINE KLINE [ :] . This command provides timed K-Lines (server-local bans). . If a client matches a K-Line, it cannot connect to this server for seconds. When is 0, it makes the K-Line permanent. . If no and no is given, the K-Line is removed. . To use this command, the user must be an IRC Operator. . "STATS k" can be used to list all currently active K-Lines. References: - This command is not specified in the IRC RFCs, it is an extension of ngIRCd. - OPER OPER . Authenticates a user named as an IRC operator on the current server/network. . This operator must be configured in the server configuration. . Please note that is NOT related to a nickname at all! References: - RFC 2812, 3.1.4 "Oper message" - REHASH REHASH . Causes the server to re-read and re-process its configuration file(s). . While rehashing, no new connections are accepted, but all already established connections stay connected. .

The first form is used by directly linked services and isn't supported by ngIRCd at the moment. The second form announces services connected to remote "pseudo-servers" ("services hubs"). . The and parameters are ignored by ngIRCd. References: - RFC 2812, 3.1.6 "Service message" - RFC 2813, 4.1.4 "Service message" - SERVLIST SERVLIST [ []] . List all IRC services currently registered in the network. . The optional and parameters can be used to limit the listing to services matching the and that are of type . . Please note that ngIRCd doesn't use any service types at the moment and therefore all services are of type "0". References: - RFC 2812, 3.5.1 "Servlist message" - SQUERY SQUERY [,[,...]] . Send a to a given IRC service, and report all errors. . The "SQUERY" command exactly behaves like the "PRIVMSG" command, but enforces that the of the is an IRC service. Please see the help text of the "PRIVMSG" command for a detailed description of the parameters! . If a user wants to interact with IRC services, he should use "SQUERY" instead of "PRIVMSG" or "NOTICE": only "SQUERY makes sure that no regular user, which uses the nickname of an IRC service, receives the command in error, for example during a "net split"! References: - RFC 2812, 2.3.1 "Message format in Augmented BNF" - RFC 2812, 3.3 "Sending messages" - RFC 2812, 3.3.2 "Notice" - SVSNICK SVSNICK . Forcefully change foreign user nicknames. This command is allowed for servers only. . The "SVSNICK" command is forwarded to the server to which the user with nickname is connected to, which in turn generates a regular "NICK" command that then is sent to the client, so no special support in the client software is required. References: - ngIRCd GIT commit e3f300d3231f Server Protocol Commands ~~~~~~~~~~~~~~~~~~~~~~~~ - CHANINFO CHANINFO + [[ ] ] . CHANINFO is used by servers to inform each other about a channel: its modes, channel key, user limits and its topic. . Note: even when don't include "k" (key) or "l" (limit), both parameters must be given when used; use "*" for "no key" and 0 for "no limit" for the unused parameter in this case. . The CHANINFO command is allowed on server-links only. References: - IRC+, - IRC+, doc/Protocol.txt - ERROR ERROR [ [<> [...]]] . Inform a client or a server about an error condition. The first parameter, if given, is logged by the server receiving the message, all other parameters are silently ignored. . This command is silently ignored on non-server and non-service links and shouldn't be used by regular IRC clients. . The ERROR message is also sent before terminating a regular client connection. References: - RFC 2812, 3.7.4 "Error message" - METADATA METADATA . The METADATA command is used on server-links to update "metadata" information of clients, like the hostname, the info text ("real name"), or the user name. . The METADATA command is allowed on server-links only. References: - IRC+, - IRC+, doc/Protocol.txt - NJOIN NJOIN [][,[][,...]] .

References: - RFC 2812, 3.1.8 "Squit" - RFC 2813, 4.1.6 "Server quit message" Dummy Commands ~~~~~~~~~~~~~~ - SUMMON SUMMON [ []] . This command was intended to call people into IRC who are directly connected to the terminal console of the IRC server -- but is deprecated today. Therefore ngIRCd doesn't really implement this command and always returns an error message, regardless of the parameters given. References: - RFC 2812, 4.5 "Summon message" - USERS USERS [] . This command was intended to list users directly logged in into the console of the IRC server -- but is deprecated today. Therefore ngIRCd doesn't really implement this command and always returns an error message, regardless of the parameters given. References: - RFC 2812, 4.6 "Users" - GET GET [...] .
