- Synopsis:
- mode <your nickname|channel> [<+|-><mode> [<mode parameter(s)>]]
-
- Description:
- Both channels and users have modes associated with them. For channels,
- they determine who is a channel operator, the number of people who may
- join the channel, who may not enter the channel, and myriad other
- things. For users, they determine whether the user will is an IRC
- operator, whether the user will receive special server notices, etc.
-
- Modes are enabled when prepended with a "+", and disabled when with a
- "-". Modes may be clustered as well. When clustering modes, all mode
- changes are specified first, then their parameters (see the examples
- below).
-
- Options:
- Standard User Modes:
- i When enabled, you are "invisible" to NAMES and WHO queries from
- anyone not on a channel common to you. Additionally, you are
- also hidden from WHOIS unless your exact nickname is specified.
- o When enabled, this gives you IRC operator status (however, see
- restrictions below).
- s When enabled, you will receive special server notices (such as
- nickname collisions, fake modes, etc.).
- w When enabled, you will receive IRC operator WALLOPS, as well as
- notices of any remote CONNECTs or SQUITs.
-
- Standard Channel Modes:
- b When enabled, this prevents the specified nick!user@host mask
- from entering the channel. If only the @host portion is
- specified, "*!*" is prepended; if only user@host is specified,
- "*!" is prepended; if the mask does not contain a "@", it is
- assumed to be a nickname, and a !*@* is appended. When used
- with no arguments, the channels list of "bans" is displayed.
- i When enabled, users may only join the channel if INVITEd.
- k When enabled, users may only join the channel if they specify
- the proper "key" (which is specified when +k is set).
- l When enabled, only the specified number of users may enter the
- channel.
- m When enabled, only users with +o or +v may speak on the channel.
- n When enabled, public messages from outside the channel are not
- allowed.
- o When enabled, grants the specified nickname channel operator
- status.
- p When enabled, the channel is made private. The channel name
- will not show up in WHO, WHOIS, NAMES, or LIST replies (though
- users who are not +i will still be shown in NAMES, the channel
- name is simply masked as "Private").
- s When enabled, makes the channel secret. This is the same as +p,
- except the channel will not show up in any WHO/WHOIS/etc.
- queries from a person not on the channel. Anyone who is on a
- +s channel is effectively invisible, as per user mode +i.
- t When enabled, only channel operators may set a topic.
- v When enabled, grants the specified nickname voice status.
-
- Examples:
- To receive operator WALLOPS and server notices (both examples are
- equivalent):
- /mode your_nick +sw
- /mode your_nick +s+w
-
- To set a channel limit (the number is arbitrary):
- /mode #channel +l 35
-
- To make someone a channel operator:
- /mode #channel +o theirnick
-
- To set a ban, a key, and to remove chanop status from someone:
- /mode #channel +bk-o *!*some@*.ban.com Secret_Key foobar
-
- See Also:
- chanmode(6); deop(4); invite(1); key(6); kick(1); on(5) mode,
- mode_stripped; oper(4); set(4) mode_stripper; usermode(6); wallops(4)
-
- Restrictions:
- Only channel operators may set modes for a channel (though anyone may
- view them), and only you may set or view your personal user modes.
- Additionally, the user mode +o may NOT be set with MODE, you must use
- the OPER command. However, it may be removed with -o (see DEOP as
- well).
-
- Also note that some server variants do not allow for redundant mode
- changes, such as "+oo foobar foobar". This shouldn't cause too many
- problems though, since you can easily reverse a mode if you wish to set
- it again, such as "-o+o foobar foobar", which is allowed.
-
- Finally, note that mode changes are limited to a maximum of 4 total
- parameters. Thus you could give +o to 3 people and set +l, but you
- could not do those and set +k as well, since that would involve 5
- parameters.
-
- Other Notes:
- On Undernet servers, the maximum number of parameters for MODE is 6.
- Additionally, some server versions have extra modes that may be used.
- Keep in mind that these do not apply everywhere, so you should check
- what software version your server is using to be sure (see VERSION).
-
- Undernet servers (ircu2.9.x):
- User Modes:
- d When enabled, your client does not receive any public messages
- from any channel you are on. (mnemonic: deaf mode)
- k No-kick mode. Any client with this mode may not be kicked from
- any channel it applies to. Limited to services.
-
- DALnet servers (ircu2.9.x+DAL, DAL4.x)
- User Modes:
- g Allows operators to see all OPER attempts, and failed server
- connects. Allows all users to see nickname collisions.
- h Shows operators the arguments to any protocol HELP command
- issued. Server numeric 310 is returned in WHOIS to denote
- +h users.
-
- IRC 2.9 servers (irc2.9.x):
- User Modes:
- r When enabled, the client cannot be a channel operator (even if
- it is the first to join), nor can it change nicknames. This
- mode is automatic if the connecting client has a matching i:
- line. This mode cannot be reversed once enabled.
- (s) Version 2.9 servers do not have a +s user mode.
-
- Channel Modes:
- a When enabled, this makes the channel anonymous. Nicknames are
- hidden (and thus nick changes are not shown), and no other
- channel modes are permitted. Note that this can seriously
- confuse the client...
-
- EFnet +CS servers (irc2.8.x+CSr27 and beyond):
- User Modes:
- b When enabled, shows connects from potential bots, and attempts
- with invalid usernames.
- c When enabled, shows all clients connecting and disconnecting
- from your server. Limited to irc operators.
- d When enabled, shows connects where the username given and the
- client's ident response differ.
- f When enabled, shows all "Fake MODE" and "Nickname Collision"
- notices.
- k When enabled, shows all global and local operator kills.
- l When enabled, shows connect attempts from clients that exceed
- their connect class (Y:line) limit.
- (r) Replaced by +bdl after CSr25.
- s When enabled, it shows any miscellaneous server notices that
- are not shown with modes bcdfklu (even if they are not
- enabled).
- u When enabled, shows all unauthorized connect attempts, as well
- as connect attempts when the server has reached its maximum
- connection limit.
-
- EFnet /th servers (irc2.8/th):
- User Modes:
- c When enabled, shows all clients connecting and disconnecting
- from your server. Limited to IRC operators.
- d Debug mode, displays miscellaneous messages. Limited to irc
- operators.
- k When enabled, shows all server kills
- n Shows all local nickname changes. Limited to irc operators.
- r When enabled, shows all rejected connections.
- s When enabled, it shows any miscellaneous server notices that
- are not shown with modes ckr, including operator kills
- y Spy mode, informs operators of all LINKS, STATS, and TRACE
- commands issued, and of any failed MSG commands.
-
- AnotherNet servers
- User Modes:
- c Show all [dis]connections, possible clones, and invalid logins
- f Show all DCC handshakes (mnemonic: file transfers)
- h Makes operator completely invisible to all normal users;
- mainly meant for channel services (mnemonic: hidden)
