-@SYNTAX:cmode@
-
- This command is used to manage the modes of the channel. Most
- of the modes require special privileges, such as channel operator
- or channel founder privileges to work. The mode is added by
- adding + before the option(s) and removed by adding - before the
- option(s). The (*) mark below means that only founder may set/unset
- that mode. Other modes both channel operator and founder may manage.
-
- The following modes are available:
-
- p Set/unset channel as private channel. Private
- channels are shown with LIST command with an
- indication the channel is private. Private
- channel is not shown on user's joined channel
- list (with for example WHOIS command).
-
- s Set/unset channel as secret channel. Secret
- channels are entirely invisible. They are not
- shown with LIST command and they do not appear
- in user's joined channel list.
-
- k Enable/disable private channel key usage. (*)
- When enabled KEY command may be used to set
- private channel key(s) on the channel.
-
- i Set/unset channel as invite only channel. If
- you are the founder of the channel you will
- still be able to join the channel by giving
- command /JOIN channel -founder.
-
- t Set/unset that only channel operator or
- founder may set channel topic
-
- m Set/unset user silencing. Normal users
- are not able to talk on channel. (*)
-
- M Set/unset operator silencing. Operators
- are not able to talk on channel. (*)
-
- l <limit> Set/unset channel's user count limit
-
- a <passphrase> Set/unset passphrase for channel that must
- be provided when joining to the channel. (*)
-
- c <cipher> Set/unset channel's cipher (*)
-
- h <hmac> Set/unset channel's HMAC (*)
-
- f [<pubkeyfile> <privkeyfile> [<privkey passphrase>]]
- Set/unset channel founder authentication. (*)
- Channel founder may set this mode so that
- when the client leaves the channel it can
- claim the founder rights when it returns
- to the channel, and to set the channel to
- be permanent channel. You can reclaim the
- founder rights using CUMODE or JOIN commands.
-
- If the <pubkeyfile> and <privkeyfile> is
- provided then the <pubkeyfile> will the used
- as founder public key, and the private key
- is used to compute a signature for the SILC
- server. If these are omitted then the default
- SILC keypair is used. Normally you do not need
- to provide these arguments.
-
- C [{[+|-]<pubkeyfile> }] (*)
- Set/unset channel public key mode, and add/remove
- channel publics key from the channel public key
- list. When this mode is set only those users
- whose public keys has been added to the list are
- able to join the channel. Channel founder may set
- this mode and operate on the channel public key
- list.
-
- To add public key to the list give command:
- CMODE +C +/path/to/the/public_key_file.pub
-
- To remove one public key from the list give
- command:
- CMODE +C -/path/to/the/public_key_file.pub
-
- To add or remove more than one public keys add as
- many public key file paths as necessary.
-
- When this mode is unset (-C), all public keys are
- removed from the list. If +C is given without
- arguments the current channel public key list is
- displayed.
-
- Multiple modes can be set/unset at once if the modes does not
- require any arguments. If mode requires an argument then only
- one mode can be set at once.
-
- When the +k (private channel key mode) mode is set the channel's
- default cipher and HMAC are not used. The private key (see /HELP KEY
- for help how to set the private channel key) defines the cipher and
- HMAC for the channel while +k mode is set. Also the +c and +h modes
- are ignored when private channel key mode is set.
-
-Examples:
-
- Set the channel a permanent (persistent). The channel won't be
- deleted when last user leaves the channel. When you as the founder
- leave the channel you will be able to reclaim the founder rights
- later.
-
- /CMODE * +f
-
- Reclaim founder rights (and operator privileges) for you channel:
-
- /CUMODE * +of mynick
-
- You can do the same during joining:
-
- /JOIN yourchannel -founder
-
- Change channel founder keypair on your channel. You can do this if
- you want to transfer founder rights to some other user or if you
- created new keypair. The operation requires that you have a copy of
- the old keypair:
-
- /CUMODE * +f mynick /path/to/old/pubkey /path/to/old/privkey
- /CMODE * +f /path/to/new/pubkey /path/to/new/privkey
-
- or simply /CMODE * +f if you are already using the new keypair.
-
- Here's how to transfer founder rights to different user using
- temporary keypair. First, create temporary keypair:
-
- # silc -C
-
- Become founder on your channel:
-
- /CUMODE * +f mynick
-
- Set the temporary keypair on the channel and then send the key
- pair to your friend with /FILE command or with encrypted Email:
-
- /CMODE * +f /path/to/temp/pubkey /path/to/temp/privkey
- (/FILE send /path/to/temp/keypair.tgz yourfriend)
-
- Tell your friend to give the following command to become founder:
-
- /CUMODE * +f yourfriend /path/to/temp/pubkey /path/to/temp/privkey
-
- Your friend then sets his own keypair on the channel:
-
- /CMODE * +f
-
- After this the temporary keypair can be removed and your friend has
- become the founder of the channel. This way the founder rights can
- be transferred without ever revealing your own keypair. When your
- friend becomes the founder your founder rights will be removed by
- the server automatically. It is also possible to continue using the
- temporary keypair, thus sharing founder rights with two or more
- users. Note that it is possible for only one user at a time to
- have founder mode on the channel even if they share the keypair.
