1 | TS6 protocol description |
2 | Written by Jilles Tjoelker | |
a5c46d31 | 3 | Edits by Elizabeth Myers to add TS rules described by Lee Harvey. |
cdff8b70 JT |
4 | |
5 | General format: much like rfc1459 | |
6 | Maximum parameters for a command: 15 (this does not include the prefix | |
7 | and command name) | |
8 | ||
9 | SID: a server's unique ID. It is configured in each server and consists of | |
10 | a digit and two alphanumerics. Sending SIDs with lowercase letters is | |
11 | questionable. | |
12 | ||
13 | UID: a client's unique ID. It consists of the server's SID and six | |
14 | alphanumerics (so it is nine characters long). The first of the alphanumerics | |
15 | should be a letter, numbers are legal but reserved for future use. | |
16 | ||
17 | hunted: a parameter type used for various remote requests. From local users, | |
18 | nicknames and server names are accepted, possibly with wildcards; from servers, | |
19 | UIDs/SIDs (sending names or even wildcards is deprecated). This is done with | |
20 | the function hunt_server(). Any rate limiting should be done locally. | |
21 | ||
a5c46d31 | 22 | |
cdff8b70 JT |
23 | duration: a parameter type used for ban durations. It is a duration in seconds. |
24 | A value of 0 means a permanent ban. | |
25 | ||
755c144e JT |
26 | IP addresses: IP addresses are converted to text in the usual way, including |
27 | '::' shortening in IPv6, with the exception that a zero is prepended to any | |
28 | IP address that starts with a colon. | |
29 | ||
03204327 JT |
30 | propagation: to which other servers the command is sent |
31 | ||
32 | For all commands with a hunted parameter, the propagation is determined by | |
33 | that, and not otherwise specified. | |
34 | ||
35 | For all commands with a target server mask parameter, the propagation is | |
36 | determined by that, and not otherwise specified. The command is sent to all | |
37 | servers with names matching the given mask (for example '*', '*.example.com', | |
38 | 'irc.example.com'). Those servers do not have to be directly connected. | |
39 | Targets cannot be SIDs. | |
40 | ||
41 | Propagation broadcast means the command is sent to all servers. | |
42 | ||
43 | Propagation one-to-one means the command is only sent to the target or the | |
44 | server the target is on. | |
45 | ||
46 | Propagation none means the command is never sent to another server if it is | |
47 | received. | |
48 | ||
49 | For some other commands, the propagation depends on the parameters and is | |
50 | described in text. | |
cdff8b70 JT |
51 | |
52 | services server: server mentioned in a service{} block. There are no services | |
53 | servers on EFnet. | |
54 | ||
55 | service: client with umode +S. This implies that it is on a services server. | |
56 | ||
aa12f64b JT |
57 | connection setup: |
58 | The initiator sends the PASS, CAPAB and SERVER messages. Upon receiving the | |
59 | SERVER, the listener will check the information, and if it is valid, it will | |
60 | send its own PASS, CAPAB and SERVER messages, followed by SVINFO and the burst. | |
61 | Upon receiving the SERVER, the initiator will send SVINFO and the burst. If | |
62 | ziplinks are used, SVINFO is the first compressed message. | |
63 | ||
13d42555 JT |
64 | The burst consists of SID and SERVER messages for all known servers, BAN |
65 | messages for all propagated bans, UID or EUID messages for all known users | |
66 | (possibly followed by ENCAP REALHOST, ENCAP LOGIN and/or AWAY) and SJOIN | |
67 | messages for all known channels (possibly followed by BMASK and/or TB). | |
aa12f64b | 68 | |
cdff8b70 JT |
69 | user modes: |
70 | (all) | |
71 | +D (deaf: does not receive channel messages) | |
72 | +S (network service) (only settable on burst from a services server) | |
73 | +a (appears as server administrator) | |
74 | +i (invisible, see rfc1459) | |
75 | +o (IRC operator, see rfc1459) | |
76 | +w (wallops, see rfc1459) (always propagated for historical reasons) | |
77 | (charybdis TS6) | |
78 | +Q/+R/+g/+l/+s/+z (only locally effective) | |
79 | +Z (ssl user) (only settable on burst) | |
80 | possibly more added by modules | |
81 | ||

83 | (all) | |
84 | statuses | |
85 | +o (prefix @) (ops) | |
86 | +v (prefix +) (voice) | |

93 | type C | |
94 | +l (limit: maximum number of members before further joins are disallowed) | |
95 | type D | |
96 | +m (moderated) | |
97 | +n (no external messages) | |
98 | +p (private: does not appear in /whois to non-members, no /knock allowed) | |
4b58bbb2 | 99 | +r (only registered users may join) (only if a services server exists) (capab: SERVICES) |
cdff8b70 JT |
100 | +s (secret) |
101 | +t (only chanops may change topic) | |
102 | (charybdis TS6) | |
103 | type A | |
104 | +q (quiet) | |
105 | type C | |
106 | +f (forward: channel name <= 30 chars) | |
107 | +j (join throttle: N:T with integer N and T) | |
108 | type D | |
109 | +F (free target for +f) | |
110 | +L (large ban list) | |
111 | +P (permanent: does not disappear when empty) | |
112 | +Q (ignore forwards to this) | |
113 | +c (strip colours) | |
114 | +g (allow any member to /invite) | |
115 | +z (send messages blocked by +m to chanops) | |
116 | ||
a5c46d31 EM |
117 | Nick TS rules: |
118 | A server receiving a command that requires nick TS rules must check for a | |
119 | collision between an existing user, and the nick in the received message. | |
120 | (the "new user"). The collisions must obey the rules specified in Nick TS | |
121 | collisions. | |
122 | ||
123 | If the TS received is lower than the TS of the existing user the server will | |
124 | collide the existing user if the clients user@host are different, if the | |
125 | clients user@hosts are identical it will collide the new user. | |
126 | ||
127 | If the TS received is equal to the TS of the existing user both clients are | |
128 | collided. | |
129 | ||
130 | If the TS received is higher than the TS of the existing user, the server | |
131 | will collide the existing user if the user@hosts are identical, if the | |
132 | clients user@host are different it will collide the new user and drop the | |
133 | message. | |
134 | ||
135 | Nick TS collisions: | |
136 | If both users are to be collided, we must issue a KILL for the existing | |
137 | user to all servers. If the new user has a UID then we must also issue a | |
138 | KILL for that UID back to the server sending us data causing the collision. | |
139 | ||
140 | If only the existing user is being collided, we must issue a KILL for the | |
141 | existing user to all servers except the server sending us data. If the | |
142 | existing user has a UID and the server sending us data supports TS6 then | |
143 | we must also issue a KILL for the existing users UID to the server sending | |
144 | us data. | |
145 | ||
146 | If only the new user is being collided, we must issue a KILL for the new user | |
147 | back to the server sending us data if the new user has a UID. | |
148 | ||
149 | Channel TS rules: | |
150 | A server receiving a command that requires normal channel TS rules must | |
151 | apply the following rules to the command. | |
152 | ||
153 | If the TS received is lower than our TS of the channel a TS6 server must | |
154 | remove status modes (+ov etc) and channel modes (+nt etc). If the | |
155 | originating server is TS6 capable (ie, it has a SID), the server must | |
156 | also remove any ban modes (+b etc). The new modes and statuses are then | |
157 | accepted. | |
158 | ||
159 | If any bans are removed, the server must send to non-TS6, directly connected | |
160 | servers mode changes removing the bans after the command is propagated. | |
161 | This prevents desync with banlists, and has to be sent after as clients are | |
162 | still able to send mode changes before the triggering command arrives. | |
163 | ||
164 | If the TS received is equal to our TS of the channel the server should keep | |
165 | its current modes and accept the received modes and statuses. | |
166 | ||
167 | If the TS received is higher than our TS of the channel the server should keep | |
168 | its current modes and ignore the received modes and statuses. Any statuses | |
169 | given in the received message will be removed. A server must mark clients | |
170 | losing their op (+o) status who do not have a UID as 'deopped'. A server must | |
171 | ignore any "MODE" commands from a user marked as 'deopped'. | |
172 | ||
173 | Simple channel TS rules: | |
174 | ||
175 | A server receiving a command that requires simple channel TS rules must | |
176 | apply the following rules to the command. | |
177 | ||
178 | If the TS received is lower, or equal to our TS of the channel the modes are | |
179 | accepted. If the TS received is higher than our TS of the channel the modes | |
180 | are ignored and dropped. | |
181 | ||
182 | Simple channel TS rules do not affect current modes in the channel except | |
183 | for the modes we are accepting. | |
184 | ||
185 | ||
f8933d67 JT |
186 | <numeric> |
187 | source: server | |
188 | parameters: target, any... | |
189 | ||
190 | The command name should be three decimal ASCII digits. | |
191 | ||
192 | Propagates a "numeric" command reply, such as from a remote WHOIS request. | |
193 | ||
194 | If the first digit is 0 (indicating a reply about the local connection), it | |
195 | should be changed to 1 before propagation or sending to a user. | |
196 | ||
197 | Numerics to the local server may be sent to opers. | |
198 | ||
199 | To avoid infinite loops, servers should not send any replies to numerics. | |
200 | ||
201 | The target can be: | |
202 | - a client | |
203 | propagation: one-to-one | |
204 | - a channel name | |
205 | propagation: all servers with -D users on the channel | |
206 | ||
207 | Numerics to channels are broken in some older servers. | |
208 | ||
cdff8b70 JT |
209 | ADMIN |
210 | source: user | |
211 | parameters: hunted | |
212 | ||
213 | Remote ADMIN request. | |
214 | ||
215 | AWAY | |
216 | source: user | |
217 | propagation: broadcast | |
218 | parameters: opt. away reason | |
219 | ||
220 | If the away reason is empty or not present, mark the user as not away. | |
221 | Otherwise, mark the user as away. | |
222 | ||
223 | Changing away reason from one non-empty string to another non-empty string | |
224 | may not be propagated. | |
225 | ||
13d42555 JT |
226 | BAN |
227 | charybdis TS6 | |
228 | capab: BAN | |
229 | source: any | |
230 | propagation: broadcast (restricted) | |
231 | parameters: type, user mask, host mask, creation TS, duration, lifetime, oper, reason | |
232 | ||
233 | Propagates a network wide ban. | |
234 | ||
a0ce140e JT |
235 | The type is K for K:lines, R for resvs and X for X:lines; other types are |
236 | reserved. The user mask field is only used for K:lines; for resvs and X:lines | |
237 | the field is ignored in input and sent as an asterisk. | |
13d42555 JT |
238 | |
239 | The creation TS indicates when this ban was last modified. An incoming ban MUST | |
240 | be ignored and not propagated if the creation TS is older than the creation TS | |
241 | of the current ban. If the ban is identical, it SHOULD NOT be propagated to | |
242 | avoid unnecessary network traffic. (Two changes to bans that set the TS to the | |
243 | same value may cause desynchronization.) | |
244 | ||
245 | The duration is 0 for an unban and relative to the creation TS for a ban. | |
246 | When the duration has passed, the ban is no longer active but it may still | |
247 | be necessary to remember it. | |
248 | ||
249 | The lifetime is relative to the creation TS and indicates for how long this | |
250 | ban needs to be remembered and propagated. This MUST be at least the duration. | |
251 | Initially, it is usually set the same as the duration but when the ban is | |
252 | modified later, it SHOULD be set such that the modified ban is remembered at | |
253 | least as long as the original ban. This ensures that the original ban does not | |
254 | revive via split servers. This requirement is only a SHOULD to allow for | |
255 | implementations that only inject bans and do not remember any; implementations | |
256 | that remember and propagate bans MUST set the lifetime appropriately. | |
257 | ||
258 | The oper field indicates the oper that originally set the ban. If this message | |
259 | is the initial propagation of a change, it SHOULD be sent as * (an asterisk). | |
260 | ||
261 | The reason field indicates the reason for the ban. Any part after a | (vertical | |
262 | bar) MUST NOT be shown to normal users. The rest of the field and the creation | |
263 | TS and duration MAY be shown to normal users. | |
264 | ||
cdff8b70 JT |
265 | BMASK |
266 | source: server | |
267 | propagation: broadcast | |
268 | parameters: channelTS, channel, type, space separated masks | |
269 | ||
270 | If the channelTS in the message is greater (newer) than the current TS of | |
271 | the channel, drop the message and do not propagate it. | |
272 | ||
273 | Type is the mode letter of a ban-like mode. In efnet TS6 this is 'b', 'e' or | |
274 | 'I'. In charybdis TS6 additionally 'q' is possible. | |
275 | ||
276 | Add all the masks to the given list of the channel. | |
277 | ||
278 | All ban-like modes must be bursted using this command, not using MODE or TMODE. | |
279 | ||
280 | CAPAB | |
281 | source: unregistered server | |
282 | propagation: none | |
283 | parameters: space separated capability list | |
284 | ||
d0c2fc82 JT |
285 | Sends capabilities of the server. This must include QS and ENCAP, and for |
286 | charybdis TS6 also EX and IE. It is also strongly recommended to include EX, | |
287 | CHW, IE and KNOCK, and for charybdis TS6 also SAVE and EUID. For use with | |
288 | services, SERVICES and RSFNC are strongly recommended. | |
aa12f64b JT |
289 | |
290 | The capabilities may depend on the configuration for the server they are sent | |
291 | to. | |
cdff8b70 JT |
292 | |
293 | CHGHOST | |
294 | charybdis TS6 | |
295 | source: any | |
296 | propagation: broadcast | |
297 | parameters: client, new hostname | |
298 | ||
299 | Changes the visible hostname of a client. | |
300 | ||
301 | Opers are notified unless the source is a server or a service. | |
302 | ||
303 | CONNECT | |
304 | source: any | |
305 | parameters: server to connect to, port, hunted | |
306 | ||
307 | Remote connect request. A server WALLOPS should be sent by the receiving | |
308 | server. | |
309 | ||
310 | The port can be 0 for the default port. | |
311 | ||
312 | DLINE | |
313 | charybdis TS6 | |
314 | encap only | |
315 | source: user | |
316 | parameters: duration, mask, reason | |
317 | ||
318 | Sets a D:line (IP ban checked directly after accepting connection). | |
319 | ||
320 | The mask must be an IP address or CIDR mask. | |
321 | ||
cbc31cce EK |
322 | ECHO |
323 | source: user | |
324 | parameters: "P"/"N", target, text | |
325 | ||
326 | As PRIVMSG, but delivers an echo-message echo to the target; they will see | |
327 | a PRIVMSG or NOTICE from themselves to the source. | |
328 | ||
cdff8b70 JT |
329 | ENCAP |
330 | source: any | |
331 | parameters: target server mask, subcommand, opt. parameters... | |
332 | ||
03204327 JT |
333 | Sends a command to matching servers. Propagation is independent of |
334 | understanding the subcommand. | |
cdff8b70 | 335 | |
03204327 | 336 | Subcommands are listed elsewhere with "encap only". |
cdff8b70 JT |
337 | |
338 | ERROR | |
339 | source: server or unregistered server | |
340 | propagation: none | |
341 | parameters: error message | |
342 | ||
343 | Reports a (usually fatal) error with the connection. | |
344 | ||
345 | Error messages may contain IP addresses and have a negative effect on server | |
346 | IP hiding. | |
347 | ||
a5de4ede JT |
348 | ETB |
349 | capab: EOPMOD | |
350 | source: any | |
351 | propagation: broadcast | |
352 | parameters: channelTS, channel, topicTS, topic setter, opt. extensions, topic | |
353 | ||
354 | Propagates a channel topic change or propagates a channel topic as part of a | |
355 | burst. | |
356 | ||
357 | If the channel had no topic yet, the channelTS in the message is lower (older) | |
358 | than the current TS of the channel, or the channelTSes are equal and the | |
359 | topicTS in the message is newer than the topicTS of the current topic on the | |
360 | channel, set the topic with topicTS and topic setter, and propagate the | |
361 | message. Otherwise ignore the message and do not propagate it. | |
362 | ||
363 | Unlike a TB message, an ETB message can change the topicTS without changing | |
364 | the topic text. In this case, the message should be propagated to servers but | |
365 | local users should not be notified. | |
366 | ||
367 | Services can send a channelTS of 0 to force restoring an older topic (unless | |
368 | the channel's TS is 0). Therefore, the channelTS should be propagated as given | |
369 | and should not be replaced by the current TS of the channel. | |
370 | ||
371 | An ETB message with a newer channelTS can still set a topic on a channel | |
372 | without topic. This corresponds to SJOIN not clearing the topic when lowering | |
373 | TS on a channel. | |
374 | ||
375 | If ETB comes from a user, it can be propagated to non-EOPMOD servers using | |
376 | TOPIC, TB or a combination of TOPIC to clear the topic and TB to set a new | |
377 | topic with topicTS. However, this can be somewhat noisy. On the other hand, if | |
378 | ETB comes from a server, there is no way to force setting a newer topicTS. It | |
379 | is possible to set the topic text but the incorrect topicTS may lead to desync | |
380 | later on. | |
381 | ||
382 | This document does not document the optional extensions between topic setter | |
383 | and topic. | |
384 | ||
cdff8b70 JT |
385 | ETRACE |
386 | encap only | |
387 | encap target: single server | |
388 | source: oper | |
389 | parameters: client | |
390 | ||
391 | Remote ETRACE information request. | |
392 | ||
393 | EUID | |
394 | charybdis TS6 | |
395 | capab: EUID | |
396 | source: server | |
397 | parameters: nickname, hopcount, nickTS, umodes, username, visible hostname, IP address, UID, real hostname, account name, gecos | |
398 | propagation: broadcast | |
399 | ||
400 | Introduces a client. The client is on the source server of this command. | |
401 | ||
755c144e JT |
402 | The IP address MUST be '0' (a zero) if the true address is not sent such as |
403 | because of a spoof. Otherwise, and if there is no dynamic spoof (i.e. the | |
404 | visible and real hostname are equal), the IP address MAY be shown to normal | |
405 | users. | |
406 | ||
1e23af24 | 407 | The account name is '*' if the user is not logged in with services. |
cdff8b70 JT |
408 | |
409 | Nick TS rules apply. | |
410 | ||
411 | EUID is similar to UID but includes the ENCAP REALHOST and ENCAP LOGIN | |
412 | information. | |
413 | ||
414 | GCAP | |
415 | encap only | |
416 | encap target: * | |
417 | source: server | |
418 | parameters: space separated capability list | |
419 | ||
420 | Capability list of remote server. | |
421 | ||
86aba27c JT |
422 | GLINE |
423 | efnet TS6 | |
424 | capab: GLN | |
425 | source: user | |
426 | parameters: user mask, host mask, reason | |
427 | propagation: broadcast | |
428 | ||
429 | Propagates a G:line vote. Once votes from three different opers (based on | |
430 | user@host mask) on three different servers have arrived, trigger the G:line. | |
431 | Pending G:lines expire after some time, usually ten minutes. Triggered G:lines | |
432 | expire after a configured time which may differ across servers. | |
433 | ||
434 | Requests from server connections must be propagated, unless they are found to | |
435 | be syntactically invalid (e.g. '!' in user mask). Therefore, disabling glines | |
436 | must not affect propagation, and too wide glines, double votes and glines that | |
437 | already exist locally must still be propagated. | |
438 | ||
439 | Of course, servers are free to reject gline requests from their own operators. | |
440 | ||
7e7004c4 JT |
441 | GUNGLINE |
442 | efnet TS6 | |
443 | encap only | |
444 | encap target: * | |
445 | source: user | |
446 | parameters: user mask, host mask, reason | |
447 | propagation: broadcast | |
448 | ||
449 | Propagates a G:line removal vote. Once three votes have arrived (as with | |
450 | G:lines), remove the G:line. Pending G:lines removals expire after some time, | |
451 | usually ten minutes. | |
452 | ||
453 | Pending G:line removals do not interact with pending G:lines. Triggering a | |
454 | G:line does not affect a pending G:line removal. Triggering a G:line removal | |
455 | does not affect a pending G:line. | |

466 | propagation: one-to-one | |
467 | ||
468 | Invites a user to a channel. | |
469 | ||
470 | If the channelTS is greater (newer) than the current TS of the channel, drop | |
471 | the message. | |
472 | ||

484 | source: user | |
485 | parameters: channelTS, channel, '+' (a plus sign) | |
486 | propagation: broadcast | |
487 | ||
488 | Joins the source user to the given channel. If the channel does not exist yet, | |
489 | it is created with the given channelTS and no modes. If the channel already | |
490 | exists and has a greater (newer) TS, wipe all simple modes and statuses and | |
491 | change the TS, notifying local users of this but not servers (note that | |
492 | ban-like modes remain intact; invites may or may not be cleared). | |
493 | ||

502 | Adds or removes a jupe for a server. If the server is presently connected, | |
503 | it MUST be SQUIT by the server's uplink when the jupe is applied. | |
504 | ||
505 | The oper field indicates the oper that originally set the jupe. If this message | |
506 | is the initial propagation of a removal, it SHOULD be sent as * (an asterisk). | |
507 | ||
508 | The reason field indicates the reason for the jupe. It SHOULD be displayed | |

516 | Kicks the target user from the given channel. | |
517 | ||
518 | Unless the channel's TS is 0, no check is done whether the source user has ops. | |

525 | propagation: broadcast | |
526 | ||
527 | Removes the user from the network. | |
528 | ||
529 | The format of the path parameter is some sort of description of the source of | |
530 | the kill followed by a space and a parenthesized reason. To avoid overflow, | |
531 | it is recommended not to add anything to the path. | |

607 | The final parameter is a list of mode letters that may not be changed by local |
608 | users. This applies to setting or unsetting simple modes, and changing or | |
609 | removing mode parameters. | |

627 | parameters: channel, cmode changes, opt. cmode parameters... | |
628 | ||
629 | Propagates a channel mode change. | |
630 | ||
631 | This is deprecated because the channelTS is not included. If it is received, | |
632 | it should be propagated as TMODE. | |

662 | If duration is greater than 0, makes the given nickname unavailable for that | |
663 | time. | |
664 | ||
665 | If duration is 0, removes a nick delay entry for the given nickname. | |

720 | must reply. | |
cdff8b70 | 721 | |
aa12f64b JT |
722 | The origin field is not used in the server protocol. It is sent as the name |
723 | (not UID/SID) of the source. | |

868 | parameters: target uid, TS | |
869 | ||
870 | Resolve a nick collision by changing a nickname to the UID. | |
871 | ||
872 | The server should verify that the UID belongs to a registered user, the user | |
873 | does not already have their UID as their nick and the TS matches the user's | |
874 | nickTS. If not, drop the message. | |
875 | ||

880 | 1. | |
881 | source: unregistered server | |
882 | parameters: server name, hopcount, server description | |
883 | ||
884 | Registers the connection as a server. PASS and CAPAB must have been sent | |
885 | before, SVINFO should be sent afterwards. | |
886 | ||
887 | If there is no such server configured or authentication failed, the connection | |
888 | should be dropped. | |
889 | ||
890 | This is propagated as a SID message. | |
891 | ||
892 | 2. | |
893 | source: server | |
894 | propagation: broadcast | |
895 | parameters: server name, hopcount, server description | |
896 | ||
897 | Introduces a new TS5 server, directly connected to the source of this command. | |
898 | This is only used for jupes as TS5 servers may do little else than existing. | |
899 | ||
900 | SID | |
901 | source: server | |
902 | propagation: broadcast | |

907 | SIGNON | |
908 | source: user | |
909 | propagation: broadcast | |
910 | parameters: new nickname, new username, new visible hostname, new nickTS, new login name | |

916 | SJOIN | |
917 | source: server | |
918 | propagation: broadcast | |
ef861b05 | 919 | parameters: channelTS, channel, simple modes, opt. mode parameters..., nicklist |
cdff8b70 JT |
920 | |
921 | Broadcasts a channel creation or bursts a channel. | |
922 | ||
923 | The nicklist consists of users joining the channel, with status prefixes for | |
924 | their status ('@+', '@', '+' or ''), for example: | |
925 | '@+1JJAAAAAB +2JJAAAA4C 1JJAAAADS'. All users must be behind the source server | |
926 | so it is not possible to use this message to force users to join a channel. | |
927 | ||
928 | The interpretation depends on the channelTS and the current TS of the channel. | |
929 | If either is 0, set the channel's TS to 0 and accept all modes. Otherwise, if | |
930 | the incoming channelTS is greater (newer), ignore the incoming simple modes | |
931 | and statuses and join and propagate just the users. If the incoming channelTS | |
932 | is lower (older), wipe all modes and change the TS, notifying local users of | |
933 | this but not servers (invites may be cleared). In the latter case, kick on | |
934 | split riding may happen: if the key (+k) differs or the incoming simple modes | |
935 | include +i, kick all local users, sending KICK messages to servers. | |
936 | ||
2d042188 JT |
937 | An SJOIN is propagated with the new TS and modes of the channel. The statuses |
938 | are propagated if and only if they were accepted. | |
939 | ||
cdff8b70 JT |
940 | SJOIN must be used to propagate channel creation and in netbursts. For regular |
941 | users joining channels, JOIN must be used. Pseudoservers may use SJOIN to join | |
942 | a user with ops. | |
943 | ||
944 | SNOTE | |
945 | charybdis TS6 | |
946 | encap only | |

953 | SQUIT | |
954 | parameters: target server, comment | |
955 | ||
956 | Removes the target server and all servers and users behind it from the network. | |
957 | ||
958 | If the target server is the receiving server or the local link this came from, | |
959 | this is an announcement that the link is being closed. | |
960 | ||
961 | Otherwise, if the target server is locally connected, the server should send | |
962 | a WALLOPS announcing the SQUIT. | |

979 | ||
980 | SVINFO | |
981 | source: server | |
982 | propagation: none | |
983 | parameters: current TS version, minimum TS version, '0', current time | |
984 | ||
985 | Verifies TS protocol compatibility and clock. If anything is not in order, | |
986 | the link is dropped. | |
987 | ||
988 | The current TS version is the highest version supported by the source server | |
989 | and the minimum TS version is the lowest version supported. | |
990 | ||
991 | The current time is sent as a TS in the usual way. | |

1003 | ||
1004 | Any of the "new" parameters can be '*' to leave the corresponding field | |
1005 | unchanged. The new login name can be '0' to log the user out. | |
1006 | ||
1007 | If the UID is registered on the network, a SIGNON with the changes will be | |
1008 | broadcast, otherwise the changes will be stored, to be used when registration | |
1009 | completes. | |

1015 | parameters: channel, topicTS, opt. topic setter, topic |
1016 | ||
1017 | Propagates a channel topic as part of a burst. | |
1018 | ||
1019 | If the channel had no topic yet or the topicTS in the message is older than | |
1020 | the topicTS of the current topic on the channel and the topics differ, set | |
1021 | the topic with topicTS and topic setter, and propagate the message. Otherwise | |
1022 | ignore the message and do not propagate it. | |
1023 | ||
1024 | If the topic setter is not present, use a server name instead. | |

1033 | source: any | |
1034 | parameters: channelTS, channel, cmode changes, opt. cmode parameters... | |
1035 | ||
1036 | Propagates a channel mode change. | |
1037 | ||
1038 | If the channelTS is greater (newer) than the current TS of the channel, drop | |
1039 | the message. | |
1040 | ||
1041 | On input, only the limit on parameters per line restricts how many cmode | |
1042 | parameters can be present. Apart from this, arbitrary modes shall be | |
1043 | processed. Redundant modes may be dropped. For example, +n-n may be applied and | |
1044 | propagated as +n-n, -n or (if the channel was already -n) nothing, but not as | |
1045 | +n. | |
1046 | ||
1047 | The parameter for mode -k (removing a key) shall be ignored. | |
1048 | ||
1049 | On output, at most ten cmode parameters should be sent; if there are more, | |
1050 | multiple TMODE messages should be sent. | |

1057 | Propagates a channel topic change. The server may verify that the source has | |
1058 | ops in the channel. | |
1059 | ||
3e0bb80a JT |
1060 | The topicTS shall be set to the current time and the topic setter shall be |
1061 | set indicating the source user. Note that this means that the topicTS of a | |
1062 | topic set with TOPIC is not necessarily consistent across the network. | |
