1# $EPIC: mode,v 1.13 2002/10/05 02:56:57 kitambi Exp $ 2Synopsis: 3 mode <your nickname|channel> [<+|-><mode> [<mode parameter(s)>]] 4 5# Currently I (hop) am renovating the structure of this help file. The 6# first part of the help file will be a basic description of the purpose 7# of modes in irc, both to users and to channels. Then a description of 8# user modes will follow, with each user mode documented and its side 9# effects explained. Each network will get a section where its deviant 10# user modes will be explained. 11# After this, a description of channel modes, with each channel mode explained. 12# Each network will get a section where its deviant channel modes will be 13# explained. 14# After all of this, will be a description of how to use the /mode command, 15# complete with examples. The first part of this help file should be put 16# in an external document at some point, but for now it's going to be in 17# here until we move it. 18 19About Modes: 20 A mode is an irc attribute which describes the current state of a channel 21 or irc user. These are called "channel modes" and "user modes". Modes 22 are traditionally single characters, usually lower case letters, and are 23 manipulated with the MODE command. You can turn on ("set") a mode by 24 prefixing the character with a plus sign ('+') and turn off ("unset") a 25 mode by prefixing the character with a minus sign ('-'). You can set or 26 unset multiple modes at a time. 27 28User Modes: 29 You can set and unset your user modes to change certain attributes about 30 your irc session. User modes are lost when your server connection ends. 31 You may be given a set of "default" user modes by your server when you 32 initially connect to it. You may be given a set of extra user modes when 33 the OPER command is successful. Some user modes are "privileged" 34 which means that you cannot turn them on yourself; the server has to 35 turn them on for you. You may not change or query the mode of any other 36 user. 37 38 Standard User Modes: 39 i "Invisible mode". Everybody is permitted to ask for a list of 40 members on a channel, or a detailed list of members on a channel 41 with the NAMES or WHO request. If the requester is a 42 member of the channel he requests, he will see the full details of 43 all other members on the channel. However, if the requester is 44 NOT a member of the channel he requests, any channel members who 45 have this user mode set will NOT be shown in the list. They will 46 be "invisible" to those who are not channel members. This same 47 effect occurs if you are a member of a secret channel (channel mode 48 +s, see below). 49 o "Operator mode". This user mode is privileged. Some irc commands 50 (relating to the administration of the irc server and network) may 51 not be executed by those who do not have this user mode set. This 52 mode must be enabled through the sucessful use of the OPER 53 command, however, it can be removed with the MODE command 54 s "Server Notices mode". The server sends out special information 55 that is not generally useful to non-techie irc users when you turn 56 this user mode on. Not every user receives every server notice just 57 because they have +s turned on. Some server notices require more 58 than one user mode to be turned on (particularly +o). The types and 59 number of messages you receive varies from server to server. 60 w "Wallops mode". Whereas server notices generally are of interest 61 to local users, WALLOPS ("Write ALL OperatorS") are of interest to 62 all privileged users on all servers. You will receive WALLOPS when 63 you turn this user mode on. Some networks restrict WALLOPS only 64 for server use. Other networks permit operators to send WALLOPS. 65 Still other networks permit everybody to send WALLOPS. As with 66 all other output modes, everything varies from server to server. 67 68 Non-standard User Modes: 69 Undernet (ircu2.9.x): 70 d "Deaf mode". The server will not send public message to this 71 client for any channels it is a member of. 72 This mode is primarily intended for services, and may or may 73 not be accessible to clients. 74 k "No-kick mode". This user mode is privileged. All servers on 75 the network will reject any attempt to KICK this client from 76 any channel it is a member of. There is no way to the server to 77 set this mode for you. 78 79 DALnet (ircu2.9.x+DAL, DAL4.x, Bahamut, Dreamforge) 80 g All will see nickname collisions. Those with user mode +o will 81 also see all uses of the OPER command and all failed/aborted 82 server connection attempts. 83 h "Help mode". This user mode is privileged. The server will 84 show you all uses of the HELP protocol command. All who WHOIS 85 you will get the 310 server numeric indicating your +h status. 86 87 IRCNet (irc2.9.x): 88 r "Restricted mode". The server will not permit this client to 89 become a channel operator either through the MODE command or 90 through the JOIN command. The server will not permit this 91 client to use the NICK command. You cannot unset this mode. 92 (s) These servers do not have the +s user mode. 93 94 EFnet [Comstud] (irc2.8.x+CSr27 and beyond): 95 b When enabled, shows connects from potential bots, and attempts 96 with invalid usernames. 97 c When enabled, shows all clients connecting and disconnecting 98 from your server. Limited to irc operators. 99 d When enabled, shows connects where the username given and the 100 client's ident response differ. 101 f When enabled, shows all "Fake MODE" and "Nickname Collision" 102 notices. 103 k When enabled, shows all global and local operator kills. 104 l When enabled, shows connect attempts from clients that exceed 105 their connect class (Y:line) limit. 106 (r) Replaced by +bdl after CSr25. 107 s When enabled, it shows any miscellaneous server notices that 108 are not shown with modes bcdfklu (even if they are not 109 enabled). 110 u When enabled, shows all unauthorized connect attempts, as well 111 as connect attempts when the server has reached its maximum 112 connection limit. 113 114 EFnet [/th] servers (irc2.8/th): 115 User Modes: 116 c When enabled, shows all clients connecting and disconnecting 117 from your server. Limited to IRC operators. 118 d Debug mode, displays miscellaneous messages. Limited to irc 119 operators. 120 k When enabled, shows all server kills 121 n Shows all local nickname changes. Limited to irc operators. 122 r When enabled, shows all rejected connections. 123 s When enabled, it shows any miscellaneous server notices that 124 are not shown with modes ckr, including operator kills 125 y Spy mode, informs operators of all LINKS , STATS , and TRACE 126 commands issued, and of any failed MSG commands. 127 128 EFnet Hybrid 6 servers (2.8/hybrid-6): 129 User Modes: 130 O Designates this client is a local IRC Operator. 131 o Designates this client is a global IRC Operator. 132 w Can see server wallops. 133 May be irc operator only depending on server configuration. 134 z Can see oper wallops. 135 No function unless irc operator. 136 s Can see generic server messages and oper kills. 137 c Can see client connections and exits. 138 No function unless irc operator. 139 r Can see 'rejected' client notices. 140 No function unless irc operator. 141 k Can see server kill messages. 142 f Can see 'I-line is full' notices. 143 No function unless irc operator. 144 y Can see stats/links/admin requests to name a few. 145 No function unless irc operator. 146 d Can see server debug messages. Note that if the server was 147 compiled with DEBUG defined, this information can potentially 148 be an invasion of user privacy. 149 Limited to irc operators with D flag. 150 n Can see client nick changes. Limited to irc operators with N flag. 151 b Can see bot detection notices. 152 No function unless irc operator 153 154 EFnet Hybrid 7 servers (2.8/hybrid-7): 155 All modes for EFNet Hybrid 6 Servers apply, and the following 156 additional modes are available, or are changed in meaning. 157 User Modes: 158 (O) Obsolete. Hybrid-7 does not support local operators. 159 a Server administrator flag. Automatically set by server in 160 conjunction with the OPER command, not usable by normal users. 161 g Reject all PRIVMSG/NOTICE not addressed to a channel, unless 162 the sender has been authorized by the ACCEPT protocol command 163 (presently you must use /quote for this) 164 165 AnotherNet servers 166 User Modes: 167 c Show all [dis]connections, possible clones, and invalid logins 168 f Show all DCC handshakes (mnemonic: file transfers) 169 h Makes operator completely invisible to all normal users; 170 mainly meant for channel services (mnemonic: hidden) 171 172 UnderNet servers 173 Server notice masks: 174 Under ircu servers the +s usermode can optionally take a numeric 175 argument prefixed by + or - 176 This argument is used to show only specific types of server messages. 177 1 unsorted old messages 178 2 server kills (nick collisions) 179 4 oper kills 180 8 desyncs (hack2) 181 16 temporary desyncs (hack3) 182 32 unauthorized connections 183 64 common TCP or socket errors 184 128 too many connections 185 256 services actions on channels (hack4) 186 512 glines 187 1024 net join/break, etc 188 2048 IP mismatches 189 4096 host throttle add/remove notices 190 8192 old oper-only messages (Oper Only) 191 16384 client connect/exit messages (Oper Only) 192 To set a server notice mask (allowing you to see that type of notice) 193 /mode <your nickname> +s +mask 194 Only one number may be specified, and it is added to your current 195 server notice mask. However you can combine values before passing them 196 to the mode command. 197 To clear a server notice mask (preventing you from seeing that type of 198 notice) 199 /mode <your nickname> +s -mask 200 Default server notice mask for users who just set +s usermode is 1540 201 (4+512+1024) 202 Default server notice mask for opers is 1799 (1+2+4+256+512+1024) 203 204 205Channel Modes: 206 You can set and unset your user modes to change certain attributes about 207 a channel. Channel modes are lost when the last person leaves a channel 208 (the channel is destroyed). Channels may be given a set of "default" 209 channel modes by the server when you create it. The first person to join 210 a channel creates it and becomes the channel operator. The mode of a 211 channel may only be changed by one of its operators. The operatorship 212 may be shared among any of the channel's members. 213 be set and unset by channel operators. 214 "prinitially nnect to it. You may be given a set of extra user modes when 215 the OPER command is successful. Some user modes are "privileged" 216 turn them on for you. You may not change or query the mode of any other 217 user. 218 219 220 Standard Channel Modes: 221 b When enabled, this prevents the specified nick!user@host mask 222 from entering the channel. If only the @host portion is 223 specified, "*!*" is prepended; if only user@host is specified, 224 "*!" is prepended; if the mask does not contain a "@", it is 225 assumed to be a nickname, and a !*@* is appended. When used 226 with no arguments, the channels list of "bans" is displayed. 227 On some servers, this also prevents any users matching the 228 specified nick!user@host mask from speaking on the channel or 229 changing nicks. 230 i When enabled, users may only join the channel if INVITE d. 231 k When enabled, users may only join the channel if they specify 232 the proper "key" (which is specified when +k is set). 233 l When enabled, only the specified number of users may enter the 234 channel. 235 m When enabled, only users with +o or +v may speak on the channel. 236 n When enabled, public messages from outside the channel are not 237 allowed. 238 o When enabled, grants the specified nickname channel operator 239 status. 240 p When enabled, the channel is made private. The channel name 241 will not show up in WHO , WHOIS , NAMES , or LIST replies (though 242 users who are not +i will still be shown in NAMES , the channel 243 name is simply masked as "Private"). 244 This no longer works as expected on all servers, as some have 245 given +p other meanings. 246 s When enabled, makes the channel secret. This is the same as +p, 247 except the channel will not show up in any WHO / WHOIS /etc. 248 queries from a person not on the channel. Anyone who is on a 249 +s channel is effectively invisible, as per user mode +i. 250 t When enabled, only channel operators may set a topic. 251 v When enabled, grants the specified nickname voice status. 252 253 254 IRCNet 255 Channel Modes: 256 a When enabled, this makes the channel anonymous. Nicknames are 257 hidden (and thus nick changes are not shown), and no other 258 channel modes are permitted. Note that this can seriously 259 confuse the client... 260 I Invite exemption. This takes a hostmask like a ban would, and 261 acts as a perminant invite. 262 e Ban exemption. Same format as +b, except user matching a 263 ban exemption can join regardless of bans. 264 265 Hybrid6 266 Channel Modes: 267 e Ban exemption. Same format as +b, except users matching a 268 ban exemption can walk through any bans matching them. 269 The server may remove ban exemptions automatically when 270 a ban-exempt client is kicked shortly after joining through 271 a ban. 272 p Paranoid. Channel operators will see when another channel 273 operator invites someone. (this differs from the old 274 chanmode p, which was formerly used for "private" mode) 275 Beware that this will not have the desired effect in a 276 mixed hybrid-6/hybrid-7 network, as +p is redefined to mean 277 knock disable in hybrid-7. 278 279 Hybrid7 280 Channel Modes: 281 a Anonymous channel operators. Channel operators will not be 282 identified as channel operators, and channel operator commands 283 will not reveal the identity of a channel operator. 284 e Ban exemption. Same format as +b, except users matching a 285 ban exemption can walk through any bans matching them. 286 The server may remove ban exemptions automatically when 287 a ban-exempt client is kicked shortly after joining through 288 a ban. 289 p Knock Disable - This differs yet again from previous uses for 290 the +p channel mode, which previously meant "private" or 291 "paranoid". Setting this mode on a channel will prevent 292 KNOCK from being used on hybrid-7 servers. This will not 293 have the expected results on a mixed hybrid-6/hybrid-7 294 network! 295 I Invite exemption. This takes a hostmask like a ban would, and 296 acts as a perminant invite. 297 298 299 300Description: 301 Both channels and users have modes associated with them. For channels, 302 they determine who is a channel operator, the number of people who may 303 join the channel, who may not enter the channel, and myriad other 304 things. For users, they determine whether the user will is an IRC 305 operator, whether the user will receive special server notices, etc. 306 307 Modes are enabled when prepended with a "+", and disabled when with a 308 "-". Modes may be clustered as well. When clustering modes, all mode 309 changes are specified first, then their parameters (see the examples 310 below). 311 312Examples: 313 To receive operator WALLOPS and server notices (both examples are 314 equivalent): 315 /mode your_nick +sw 316 /mode your_nick +s+w 317 318 To set a channel limit (the number is arbitrary): 319 /mode #channel +l 35 320 321 To make someone a channel operator: 322 /mode #channel +o theirnick 323 324 To set a ban, a key, and to remove chanop status from someone: 325 /mode #channel +bk-o *!*some@*.ban.com Secret_Key foobar 326 327See Also: 328 chanmode (6); deop (4); invite (1); key (6); kick (1); on (5) mode , 329 mode_stripped ; oper (4); set (4) mode_stripper ; usermode (6); wallops (4) 330 331Restrictions: 332 Only channel operators may set modes for a channel (though anyone may 333 view them), and only you may set or view your personal user modes. 334 Additionally, the user mode +o may NOT be set with MODE , you must use 335 the OPER command. However, it may be removed with -o (see DEOP as 336 well). 337 338 Also note that some server variants do not allow for redundant mode 339 changes, such as "+oo foobar foobar". This shouldn't cause too many 340 problems though, since you can easily reverse a mode if you wish to set 341 it again, such as "-o+o foobar foobar", which is allowed. 342 343 Finally, note that mode changes are limited to a maximum of 4 total 344 parameters. Thus you could give +o to 3 people and set +l, but you 345 could not do those and set +k as well, since that would involve 5 346 parameters. 347 348Other Notes: 349 On Undernet servers, the maximum number of parameters for MODE is 6. 350 Additionally, some server versions have extra modes that may be used. 351 Keep in mind that these do not apply everywhere, so you should check 352 what software version your server is using to be sure (see VERSION ). 353 354 Undernet servers (ircu2.9.x): 355 User Modes: 356 d When enabled, your client does not receive any public messages 357 from any channel you are on. (mnemonic: deaf mode) 358 k No-kick mode. Any client with this mode may not be kicked from 359 any channel it applies to. Limited to services. 360 361 DALnet servers (ircu2.9.x+DAL, DAL4.x) 362 User Modes: 363 g Allows operators to see all OPER attempts, and failed server 364 connects. Allows all users to see nickname collisions. 365 h Shows operators the arguments to any protocol HELP command 366 issued. Server numeric 310 is returned in WHOIS to denote 367 +h users. 368 369 IRC 2.9 servers (irc2.9.x): 370 User Modes: 371 r When enabled, the client cannot be a channel operator (even if 372 it is the first to join), nor can it change nicknames. This 373 mode is automatic if the connecting client has a matching i: 374 line. This mode cannot be reversed once enabled. 375 (s) Version 2.9 servers do not have a +s user mode. 376 377 Channel Modes: 378 a When enabled, this makes the channel anonymous. Nicknames are 379 hidden (and thus nick changes are not shown), and no other 380 channel modes are permitted. Note that this can seriously 381 confuse the client... 382 383 EFnet +CS servers (irc2.8.x+CSr27 and beyond): 384 User Modes: 385 b When enabled, shows connects from potential bots, and attempts 386 with invalid usernames. 387 c When enabled, shows all clients connecting and disconnecting 388 from your server. Limited to irc operators. 389 d When enabled, shows connects where the username given and the 390 client's ident response differ. 391 f When enabled, shows all "Fake MODE" and "Nickname Collision" 392 notices. 393 k When enabled, shows all global and local operator kills. 394 l When enabled, shows connect attempts from clients that exceed 395 their connect class (Y:line) limit. 396 (r) Replaced by +bdl after CSr25. 397 s When enabled, it shows any miscellaneous server notices that 398 are not shown with modes bcdfklu (even if they are not 399 enabled). 400 u When enabled, shows all unauthorized connect attempts, as well 401 as connect attempts when the server has reached its maximum 402 connection limit. 403 404 EFnet /th servers (irc2.8/th): 405 User Modes: 406 c When enabled, shows all clients connecting and disconnecting 407 from your server. Limited to IRC operators. 408 d Debug mode, displays miscellaneous messages. Limited to irc 409 operators. 410 k When enabled, shows all server kills 411 n Shows all local nickname changes. Limited to irc operators. 412 r When enabled, shows all rejected connections. 413 s When enabled, it shows any miscellaneous server notices that 414 are not shown with modes ckr, including operator kills 415 y Spy mode, informs operators of all LINKS , STATS , and TRACE 416 commands issued, and of any failed MSG commands. 417 EFnet Hybrid 6 servers (2.8/hybrid-6): 418 User Modes: 419 O Designates this client is a local IRC Operator. 420 o Designates this client is a global IRC Operator. 421 w Can see server wallops. 422 May be irc operator only depending on server configuration. 423 z Can see oper wallops. 424 No function unless irc operator. 425 s Can see generic server messages and oper kills. 426 c Can see client connections and exits. 427 No function unless irc operator. 428 r Can see 'rejected' client notices. 429 No function unless irc operator. 430 k Can see server kill messages. 431 f Can see 'I-line is full' notices. 432 No function unless irc operator. 433 y Can see stats/links/admin requests to name a few. 434 No function unless irc operator. 435 d Can see server debug messages. 436 Limited to irc operators with D flag. 437 n Can see client nick changes. Limited to irc operators with N flag. 438 Channel Modes: 439 e Ban exemption. Same format as +b, except users matching a 440 ban exemption can walk through any bans matching them. 441 p Paranoid. Channel operators will see when another channel 442 operator invites someone. (this differs from the old 443 chanmode p, which was formerly used for "private" mode) 444 445 EFnet Hybrid 7 servers (2.8/hybrid-7): 446 All modes for EFNet Hybrid 6 Servers apply, and the following 447 additional modes are available, or are changed in meaning. 448 User Modes: 449 a Server administrator flag. Automatically set by server in 450 conjunction with the OPER command, not usable by normal users. 451 g Reject all PRIVMSG/NOTICE not addressed to a channel, unless 452 the sender has been authorized by the ACCEPT protocol command 453 (presently you must use /quote for this) 454 Channel Modes: 455 a Anonymous channel operators. Channel operators will not be 456 identified as channel operators, and channel operator commands 457 will not reveal the identity of a channel operator. 458 I Standing Invitation. Format is the same as a ban. Users matching 459 will be able to join regardless of the +i mode, as if they had 460 been given an INVITE by one of the ops. 461 462 AnotherNet servers 463 User Modes: 464 c Show all [dis]connections, possible clones, and invalid logins 465 f Show all DCC handshakes (mnemonic: file transfers) 466 h Makes operator completely invisible to all normal users; 467 mainly meant for channel services (mnemonic: hidden) 468 469 UnderNet servers 470 Server notice masks: 471 Under ircu servers the +s usermode can optionally take a numeric 472 argument prefixed by + or - 473 This argument is used to show only specific types of server messages. 474 1 unsorted old messages 475 2 server kills (nick collisions) 476 4 oper kills 477 8 desyncs (hack2) 478 16 temporary desyncs (hack3) 479 32 unauthorized connections 480 64 common TCP or socket errors 481 128 too many connections 482 256 services actions on channels (hack4) 483 512 glines 484 1024 net join/break, etc 485 2048 IP mismatches 486 4096 host throttle add/remove notices 487 8192 old oper-only messages (Oper Only) 488 16384 client connect/exit messages (Oper Only) 489 To set a server notice mask (allowing you to see that type of notice) 490 /mode <your nickname> +s +mask 491 Only one number may be specified, and it is added to your current 492 server notice mask.
