Except STATS letters, all commands and names are case insensitive. CONNECT target port source Initiate a connection attempt to server target. If a port is given, connect to that port on the target, otherwise use the one given in ircd.conf. If source is given, tell that server to initiate the connection attempt, otherwise it will be made from the server you are attached to. SQUIT server reason Closes down the link to server from this side of the network. If a reason is given, it will be sent out in the server notices on both sides of the link. REHASH BANS DNS MOTD OMOTD GLINES PGLINES TKLINES TDLINES TXLINES TRESVS REJECTCACHE HELP server With no parameter given, ircd.conf will be reread and parsed. The server argument is a wildcard match of server names. BANS Rereads kline.conf, dline.conf, xline.conf, resv.conf and their .perm variants DNS Reread /etc/resolv.conf. MOTD Reload the MOTD file OMOTD Reload the operator MOTD file GLINES Clears G:lines. PGLINES Clears pending G:lines. TKLINES Clears temporary K:lines. TDLINES Clears temporary D:lines. TXLINES Clears temporary X:lines. TRESVS Clears temporary reservations. REJECTCACHE Clears the client rejection cache. HELP Refreshes the help system cache. RESTART server Cause an immediate total shutdown of the IRC server, and restart from scratch as if it had just been executed. This reexecutes the ircd using the compiled-in path, visible as SPATH in INFO. This command cannot be used remotely. The server name is used only as a safety measure. DIE server Immediately terminate the IRC server, after sending notices to all connected clients and servers This command cannot be used remotely. The server name is used only as a safety measure. SET LOG MAX SPLITDELAY SMALLNET SPAMNUM SPAMTIME value The SET command sets a runtime-configurable value LOG Logging level for ircd.log and syslog MAX Set the maximum connections allowed (may not exceed the compiled-in value HARD_FDLIMIT) DRONETIME Number of seconds in which DRONECOUNT messages must occur to trip the drone alarm DRONECOUNT Number of messages which constitutes a drone flood. 0 disables drone flood checking. SPLITDELAY Number of minutes after a connect burst begins until joining an empty channel will give you ops SMALLNET Sets the number of servers which are needed to constitute attached to the network, as opposed to split SPAMNUM Sets the number of JOINs/PARTs which constitutes a possible spambot SPAMTIME Staying on a channel for less than this length of time adds to the SPAMNUM count KILL nick reason Disconnects the user with the given nick from the server they are connected to, with the reason given, if present, and broadcast a server notice announcing this. Your nick and the reason will appear on channels. Closes all connections from and to clients and servers who have not completed registering. KLINE length user@host user@a.b.c.d ON servername :reason Adds a K:line to kline.conf to ban the given user@host from using that server. If the optional parameter length is given, the K:line will be temporary (i.e. it will not be stored on disk) and last that long in minutes. If an IP address is given, the ban will be against all hosts matching that IP regardless of DNS. The IP address can be given as a full address (192.168.0.1), as a CIDR mask (192.168.0.0/24), or as a glob (192.168.0.*). All clients matching the K:line will be disconnected from the server immediately. If a reason is specified, it will be sent to the client when they are disconnected, and whenever a connection is attempted which is banned. If the ON part is specified, the K:line is set on servers matching the given mask (provided a matching shared{} block exists there). Otherwise, if specified in a cluster{} block, the K:Line will be propagated across the network accordingly. UNKLINE user@host ON servername Will attempt to remove a K:line matching user@host from kline.conf, and will flush a temporary K:line. XLINE length mask ON servername :reason Works similarly to KLINE, but matches against the real name field. The wildcards are * (any sequence), ? (any character), # (a digit) and @ (a letter); wildcard characters can be escaped with a backslash. Use \s for a space; this currently interferes with the check whether the mask is already xlined and UNXLINE. All clients matching the X:line will be disconnected from the server immediately. The reason is never sent to users. Instead, they will be exited with Bad user info. If the ON part is specified, the X:line is set on servers matching the given mask (provided a matching shared{} block exists there). Otherwise, if specified in a cluster{} block, the X:line will be propagated across the network accordingly. UNXLINE mask ON servername Will attempt to remove an X:line from xline.conf, and will flush a temporary X:line. RESV length channel mask ON servername :reason If used on a channel, jupes the channel locally. Joins to the channel will be disallowed and generate a server notice on +y, and users will not be able to send to the channel. Channel jupes cannot contain wildcards. If used on a nickname mask, prevents local users from using a nick matching the mask (the same wildcard characters as xlines). There is no way to exempt the initial nick from this. In neither case will current users of the nick or channel be kicked or disconnected. This facility is not designed to make certain nicks or channels oper-only. The reason is never sent to users. If the ON part is specified, the resv is set on servers matching the given mask (provided a matching shared{} block exists there). Otherwise, if specified in a cluster{} block, the resv will be propagated across the network accordingly. UNRESV channel mask ON servername Will attempt to remove a resv from resv.conf, and will flush a temporary resv. DLINE length a.b.c.d :reason Adds a D:line to dline.conf, which will deny any connections from the given IP address. The IP address can be given as a full address (192.168.0.1) or as a CIDR mask (192.168.0.0/24). If the optional parameter length is given, the D:line will be temporary (i.e. it will not be stored on disk) and last that long in minutes. All clients matching the D:line will be disconnected from the server immediately. If a reason is specified, it will be sent to the client when they are disconnected, and, if dline_reason is enabled, whenever a connection is attempted which is banned. D:lines are less load on a server, and may be more appropriate if somebody is flooding connections. D:lines cannot be set remotely on other servers. Only exempt{} blocks exempt from D:lines. Being a server or having kline_exempt in auth{} does not exempt (different from K/G/X:lines). UNDLINE a.b.c.d Will attempt to remove a D:line from dline.conf, and will flush a temporary D:line. GLINE user@host user@a.b.c.d :reason Attempts to add a network-wide ban for the given mask. It takes three different opers on three different servers requesting the same G:line to have it triggered for a configured time. Once triggered, a G:line is similar to a temporary K:line on each server. No further propagation or on-disk storage is done. This command can be enabled or disabled in the configuration file. If it is disabled, no oper on the server can issue a G:line and no G:lined user is banned, but G:lines are still propagated to other servers which may have G:lines enabled. UNGLINE user@host user@a.b.c.d Removes the given G:line on this server. TESTGECOS gecos Looks up X:Lines matching the given gecos. TESTLINE nick! user@host a.b.c.d Looks up the given hostmask or IP address and reports back on any auth{} blocks, D:, G:, or K: lines found. If nick is given, also searches for nick resvs. For temporary items the number of minutes until the item expires is shown (as opposed to the hit count in STATS q/Q/x/X). This command will not perform DNS lookups; for best results you must testline a host and its IP form. The given username should begin with a tilde (~) if identd is not in use. As of charybdis 2.1.1, no_tilde and username truncation will be taken into account like in the normal client access check. As of charybdis 2.2.0, a channel name can be specified and the RESV will be returned, if there is one. TESTMASK hostmask gecos Searches the network for users that match the hostmask and gecos given, returning the number of matching users on this server and other servers. The hostmask is of the form user@host or user@ip/cidr with * and ? wildcards, optionally preceded by nick!. The gecos field accepts the same wildcards as xlines. The IP address checked against is 255.255.255.255 if the IP address is unknown (remote client on a TS5 server) or 0 if the IP address is hidden (auth{} spoof). LUSERS mask nick server Shows various user and channel counts. The mask parameter is obsolete but must be used when querying a remote server. TRACE server nick location With no argument or one argument which is the current server, TRACE gives a list of all connections to the current server and a summary of connection classes. With one argument which is another server, TRACE displays the path to the specified server, and all servers, opers and -i users on that server, along with a summary of connection classes. With one argument which is a client, TRACE displays the path to that client, and that client's information. If location is given, the command is executed on that server; no path is displayed. When listing connections, type, name and class is shown in addition to information depending on the type: Try. A server we are trying to make a TCP connection to. H.S. A server we have established a TCP connection to, but is not yet registered. ???? An incoming connection that has not yet registered as a user or a server (unknown). Shows the username, hostname, IP address and the time the connection has been open. It is possible that the ident or DNS lookups have not completed yet, and in any case no tildes are shown here. Unknown connections may not have a name yet. User A registered unopered user. Shows the username, hostname, IP address, the time the client has not sent anything (as in STATS l) and the time the user has been idle (from PRIVMSG only, as in WHOIS). Oper Like User, but opered. Serv A registered server. Shows the number of servers and users reached via this link, who made this connection and the time the server has not sent anything. ETRACE nick Shows client information about the given target, or about all local clients if no target is specified. MASKTRACE hostmask gecos Searches the local server or network for users that match the hostmask and gecos given. Network searches require the oper_spy privilege and an '!' before the hostmask. The matching works the same way as TESTMASK. The hostmask is of the form user@host or user@ip/cidr with * and ? wildcards, optionally preceded by nick!. The gecos field accepts the same wildcards as xlines. The IP address field contains 255.255.255.255 if the IP address is unknown (remote client on a TS5 server) or 0 if the IP address is hidden (auth{} spoof). CHANTRACE channel Displays information about users in a channel. Opers with the oper_spy privilege can get the information without being on the channel, by prefixing the channel name with an '!'. The IP address field contains 255.255.255.255 if the IP address is unknown (remote client on a TS5 server) or 0 if the IP address is hidden (auth{} spoof). SCAN UMODES +modes-modes no-list list global list-max number mask nick!user@host Searches the local server or network for users that have the umodes given with + and do not have the umodes given with -. no-list disables the listing of matching users and only shows the count. list enables the listing (default). global extends the search to the entire network instead of local users only. list-max limits the listing of matching users to the given amount. mask causes only users matching the given nick!user@host mask to be selected. Only the displayed host is considered, not the IP address or real host behind dynamic spoofs. The IP address field contains 255.255.255.255 if the IP address is unknown (remote client on a TS5 server) or 0 if the IP address is hidden (auth{} spoof). Network searches where a listing is given or the mask option is used are operspy commands. CHGHOST nick value Set the hostname associated with a particular nick for the duration of this session. This command is disabled by default because of the abuse potential and little practical use. ADMIN nick server Shows the information in the admin{} block. INFO nick server Shows information about the authors of the IRC server, and some information about this server instance. Opers also get a list of configuration options. TIME nick server Shows the local time on the given server, in a human-readable format. VERSION nick server Shows version information, a few compile/config options, the SID and the 005 numerics. The 005 numeric will be remapped to 105 for remote requests. STATS type nick server Display various statistics and configuration information. A Show DNS servers b Show active nick delays B Show hash statistics c Show connect blocks d Show temporary D:lines D Show permanent D:lines e Show exempt blocks (exceptions to D:lines) E Show events f Show file descriptors g Show pending glines G Show active glines h Show hub_mask/leaf_mask i Show auth blocks, or matched auth blocks k Show temporary K:lines, or matched K:lines K Show permanent K:lines, or matched K:lines l Show hostname and link information about the given nick. With a server name, show information about opers and servers on that server; opers get information about all local connections if they query their own server. No hostname is shown for server connections. L Like l, but show IP address instead of hostname m Show commands and their usage statistics (total counts, total bytes, counts from server connections) n Show blacklist blocks (DNS blacklists) with hit counts since last rehash and (parenthesized) reference counts. The reference count shows how many clients are waiting on a lookup of this blacklist or have been found and are waiting on registration to complete. o Show operator blocks p Show logged on network operators which are not set AWAY. P Show listen blocks (ports) q Show temporarily resv'ed nicks and channels with hit counts Q Show permanently resv'ed nicks and channels with hit counts since last rehash bans r Show resource usage by the ircd t Show generic server statistics about local connections u Show server uptime U Show shared (c), cluster (C) and service (s) blocks v Show connected servers and brief status x Show temporary X:lines with hit counts X Show permanent X:lines with hit counts since last rehash bans y Show class blocks z Show memory usage statistics Z Show ziplinks statistics ? Show connected servers and link information about them WALLOPS :message Sends a WALLOPS message to all users who have the +w umode set. This is for things you don't mind the whole network knowing about. OPERWALL :message Sends an OPERWALL message to all opers who have the +z umode set. +z is restricted, OPERWALL should be considered private communications.
