4 This command is used to manage the modes of the channel. Most
5 of the modes require special privileges, such as channel operator
6 or channel founder privileges to work. The mode is added by
7 adding + before the option(s) and removed by adding - before the
8 option(s). The (*) mark below means that only founder may set/unset
9 that mode. Other modes both channel operator and founder may manage.
11 The following modes are available:
13 p Set/unset channel as private channel
14 s Set/unset channel as secret channel. Secret
15 channel are not shown in user's channel list
16 or with /LIST command.
17 k Enable/disable channel private key usage (*)
18 i Set/unset channel as invite only channel
19 t Set/unset that only channel operator or
20 founder may set channel topic
21 m Set/unset user silencing. Normal users
22 are not able to talk on channel. (*)
23 M Set/unset operator silencing. Operators
24 are not able to talk on channel. (*)
25 l <limit> Set/unset channel's user limit
26 a <passphrase> Set/unset passphrase for channel that must
27 be provided when joining to the channel. (*)
28 c <cipher> Set/unset channel's cipher (*)
29 h <hmac> Set/unset channel's hmac (*)
30 f [<pubkeyfile> <privkeyfile> [<privkey passphrase>]]
31 Set/unset channel founder authentication. (*)
32 Channel founder may set this mode so that
33 if the client leaves the channel it can
34 claim the founder rights when it returns
35 to the channel, and to set the channel to
36 be permanent channel. You can claim the
37 founder rights using CUMODE or JOIN commands.
39 If the <pubkeyfile> and <privkeyfile> is
40 provided then the <pubkeyfile> will the used
41 as founder public key, and the private key
42 is used to compute a signature for the SILC
43 server. If these are omitted then the default
44 SILC keypair is used. Normally you do not need
45 to provide these arguments.
46 C [{[+|-]<pubkeyfile> }] (*)
47 Set/unset channel public key mode, and add/remove
48 channel publics key from the channel public key
49 list. When this mode is set only those users
50 whose public keys has been added to the list are
51 able to join the channel. Channel founder may set
52 this mode and operate on the channel public key
55 To add public key to the list give command:
56 CMODE +C +/path/to/the/public_key_file.pub
58 To remove one public key from the list give
60 CMODE +C -/path/to/the/public_key_file.pub
62 To add or remove more than one public keys add as
63 many public key file paths as necessary.
65 When this mode is unset (-C), all public keys are
66 removed from the list. If +C is given without
67 arguments the current channel public key list is
70 Multiple modes can be set/unset at once if the modes does not
71 require any arguments. If mode requires an argument then only
72 one mode can be set at once.
74 When the +k (channel private key mode) mode is set the channel's
75 default cipher and HMAC are not used. The private key (see /HELP KEY
76 for help how to set the private key) defines the cipher and HMAC for
77 the channel while +k mode is set. Also the +c and +h modes are ignored
78 when channel private key is set.
