How to change a channel mode
To change a mode on a channel, use the
/mode command with the channel mode you wish to change. For example:
To set +c on the channel #example:
/mode #example +c
Or to unset it:
/mode #example -c
NOTE: Some channels make use of ChanServ to lock certain modes from being unset (or even set, in some cases). By default, channel modes +n and +t are locked on all newly registered channels so they usually cannot be unset.
Standalone Channel Modes
These channel modes don't have any parameters, you simply set or unset them.
|c||No control codes||Blocks messages containing control codes (color, bold, underline, etc) from being sent to the channel|
|i||Invite only||Makes the channel invite-only. Users must be invited by a channel operator in the channel with the |
|m||Moderated||Mutes the channel - users who do not have at least voice (+v) or higher cannot talk in the channel.|
|n||No external messages||Blocks external messages to the channel from outside the channel. In other words, you cannot |
|p||Private||Marks the channel as private - the channel will not be shown in any user's |
|s||Secret||Marks the channel as secret - the channel will not be shown in any user's |
|t||(Half)Ops topic||Restricts changing the channel's topic to those with half-operator (+h) or higher. NOTE: This mode is usually locked on by default, via ChanServ's mode locking, and thus cannot usually be unset.|
|u||Auditorium||Changes the channel into an "auditorium" - you can only see yourself, and cannot see joins, parts, quits, or kicks in the channel. It is intended to save bandwidth. Note that Xertion network staff can still see all activity in an auditorium channel.|
|z||SSL only||Users can only join if they are connected using SSL. NOTE: This mode cannot be set unless existing users in the channel are already connected using SSL!|
|A||Allow Invite||Permits any user to use |
|B||Block Caps||Blocks messages with too many capital letters, as determined by the network configuration|
|C||No CTCPs||Blocks users from sending CTCPs to the channel. This does NOT block /me however (CTCP ACTION).|
|D||Delayed Join||Joins from users are not shown until they speak in the channel.|
|G||Censor||Filters predefined words from channel messages, replacing them with "(censored)". For a list of words filtered by this mode, see Censorship list.|
|M||Mute unregistered||Prevents unregistered and/or unidentified users from speaking in the channel. A user will need to either register or identify to NickServ in order to talk.|
|N||No nick changes||Blocks nickname changes from any user that does not have at least voice (+v) or higher.|
|Q||Restricted Kick||Disallows use of the |
|R||Registered only||Users must be registered with AND identified to NickServ to join. Users must be using a nickname on their account's group list in order to join - identifying to an account from an unregistered nickname will NOT suffice.|
|S||Strip Colors||Strips all control codes from incoming messages to the channel, but does not block the message. Less restrictive than +c.|
|T||No notices||Blocks users from sending notices to the channel using |
Channel Modes requiring a parameter
To set these modes, you need to provide one or more parameters to set it. Most modes do not require the same parameters to be unset. The exception is channel mode +k, which also requires a parameter to unset as well.
|k||Key||Sets a key on a channel. You can think of it as a password to enter the channel. If you have the password, you can join the channel like so: |
To set this mode:
NOTE: You must specify the SAME key you used when setting this mode, in order to unset it.
|F||Nick Flood||Restricts the number of nickname changes in a channel to x changes every y seconds.
|J||Delay Rejoin||Delays a user from automatically rejoining for the specified number of seconds after being kicked from the channel.
|L||Redirect/Link||(used with channel mode l) When channel is full as per channel mode l, redirects users to the specified channel.
|d||Delay Message||Blocks messages from users until they've been joined to the channel for the given number of seconds.
|f||Message Flood||Kicks and optionally bans users who exceed the given number of messages in a given number of seconds.
|j||Join Flood||Blocks joins to the channel for 60 seconds if joins exceed a specified number within a given number of seconds.
NOTE: The join lockout of 60 seconds can be cancelled by simply removing and resetting channel mode +j, which has the effect of resetting the lockout timer.
|l||Limit||Sets the maximum number of users permitted in the channel to the given number.
|v||Voice||Gives the specified user voice - they can speak when channel mode +m is set, and are not affected by restrictive extended bans.|
|h||Half-operator||Gives the specified user half-operator - they are able to toggle select channel modes, can kick users who have voice (+v) or below, can give voice to others, and can change the channel's topic. They cannot kick or remove the modes of channel operators (+o) and above, and they cannot toggle channel modes reserved for channel operators and up.|
|o||Channel operator||Gives the specified user channel operator - they can toggle most channel modes except +a and +q, can kick other opped users and below, and can grant or remove chanop or halfop from others. Chanops cannot perform actions on channel owners or channel administrators.|
|a||Protected/Admin||Gives the specified user channel admin - the same access rights as channel operators apply here as well, with the exception that protected/admin users can kick other protected/admin users. Protected/admin users cannot take actions against channel owners.|
|q||Owner||Gives the specified user channel owner - this grants full control over virtually all aspects of the channel, including the ability to toggle any channel mode (except those only settable by IRC operators), kick anyone, and set/unset +v/+h/+o/+a/+q on other users.|
List-type Channel Modes
These modes store parameters in a list. Those that take a nick!user@host mask can also make use of Extended Bans.
|b||Channel ban||Prevents users matching a nick!user@host mask from joining, or prevents matching users from speaking in the channel.
|e||Channel exemption||Exempts users matching a nick!user@host mask from a matching ban.
|I||Invite exemption (invex)||Allows a user matching a nick!user@host mask to join an invite-only (+i) channel without having to be invited with |
|g||Channel censor||Filters messages containing the specified text anywhere in the message from being sent to the channel. Unlike +G, the message is completely blocked if it contains the text anywhere in the message. Wildcards are accepted but not usually needed. Example: |
You can view a channel's censor list by typing
|w||Channel ACL||Grants users matching masks the specified mode. Some ExtBans can be used here. Example: |
You can view a channel's internal access list by typing
|X||Exempt Chanops||Exempts users with specific access from specific channel restrictions, for more information see ExemptChanops
NOTE: Despite the name "exempt chanops" this mode can, in fact, be used to apply the exemption to any specific level of channel access.
Restricted Channel Modes
These modes can be set/unset ONLY by either an IRC Operator and/or network Services, not by normal users!
|O||Oper Only||Only IRC Operators can join the channel|
|P||Permanent||Marks the channel as permanent. Permanent channels will remain open even when all users have left, thereby preserving things like modes, ban lists, and the topic.|
|Y||Oper Prefix||Marks the user as an IRC Operator in the channel with a ! prefix.|
|r||Registered Channel||Marks the channel as a registered channel. Only network Services can set/unset this.|
