5soju - IRC bouncer

7# SYNOPSIS
8
9*soju* [options...]
10
11# DESCRIPTION
12
13soju is a user-friendly IRC bouncer. It connects to upstream IRC servers on
14behalf of the user to provide extra features.
15
16- Multiple separate users sharing the same bouncer, each with their own
17 upstream servers
18- Clients connecting to multiple upstream servers via a single connection to
19 the bouncer
20- Sending the backlog (messages received while the user was disconnected from
21 the bouncer), with per-client buffers
22
23When joining a channel, the channel will be saved and automatically joined on
24the next connection. When registering or authenticating with NickServ, the
25credentials will be saved and automatically used on the next connection if the
26server supports SASL. When parting a channel with the reason "detach", the
27channel will be detached instead of being left.
28
29When all clients are disconnected from the bouncer, the user is automatically
30marked as away.
31
32soju supports two connection modes:
33
34- Single upstream mode: one downstream connection maps to one upstream
35 connection. To enable this mode, connect to the bouncer with the username
36 "<username>/<network>". If the bouncer isn't connected to the upstream
37 server, it will get automatically added. Then channels can be joined and
38 parted as if you were directly connected to the upstream server.
39- Multiple upstream mode: one downstream connection maps to multiple upstream
40 connections. Channels and nicks are suffixed with the network name. To join
41 a channel, you need to use the suffix too: _/join #channel/network_. Same
42 applies to messages sent to users.
43
44For per-client history to work, clients need to indicate their name. This can
45be done by adding a "@<client>" suffix to the username.
46
47soju will reload the configuration file, the TLS certificate/key and the MOTD
48file when it receives the HUP signal. The configuration options _listen_, _db_
49and _log_ cannot be reloaded.
50
51Administrators can broadcast a message to all bouncer users via _/notice
52$<hostname> <text>_, or via _/notice $\* <text>_ in multi-upstream mode. All
53currently connected bouncer users will receive the message from the special
54_BouncerServ_ service.
55
56# OPTIONS
57
58*-h, -help*
59 Show help message and quit.
60
61*-config* <path>
62 Path to the config file. If unset, a default config file is used.
63
64*-debug*
65 Enable debug logging (this will leak sensitive information such as
66 passwords).
67
68*-listen* <uri>
69 Listening URI (default: ":6697"). Can be specified multiple times.
70
71# CONFIG FILE
72
73The config file has one directive per line.
74
75Example:
76
77```
78listen ircs://
79tls cert.pem key.pem
80hostname example.org
81```
82
83The following directives are supported:
84
85*listen* <uri>
86 Listening URI (default: ":6697").
87
88 The following URIs are supported:
89
90 - _[ircs://][host][:port]_ listens with TLS over TCP (default port if
91 omitted: 6697)
92 - _irc+insecure://[host][:port]_ listens with plain-text over TCP (default
93 port if omitted: 6667)
94 - _unix:///<path>_ listens on a Unix domain socket
95 - _wss://[host][:port]_ listens for WebSocket connections over TLS (default
96 port: 443)
97 - _ws+insecure://[host][:port]_ listens for plain-text WebSocket
98 connections (default port: 80)
99 - _ident://[host][:port]_ listens for plain-text ident connections (default
100 port: 113)
101 - _http+prometheus://localhost:<port>_ listens for plain-text HTTP
102 connections and serves Prometheus metrics (host must be "localhost")
103 - _http+pprof://localhost:<port>_ listens for plain-text HTTP connections
104 and serves pprof runtime profiling data (host must be "localhost"). For
105 more information, see: <https://pkg.go.dev/net/http/pprof>.
106
107 If the scheme is omitted, "ircs" is assumed. If multiple *listen*
108 directives are specified, soju will listen on each of them.
109
110*hostname* <name>
111 Server hostname (default: system hostname).
112
113*title* <title>
114 Server title. This will be sent as the _ISUPPORT NETWORK_ value when clients
115 don't select a specific network.
116
117*tls* <cert> <key>
118 Enable TLS support. The certificate and the key files must be PEM-encoded.
119
120*db* <driver> <source>
121 Set the database location for user, network and channel storage. By default,
122 a _sqlite3_ database is opened in "./soju.db".
123
124 Supported drivers:
125
126 - _sqlite3_ expects _source_ to be a path to the SQLite file
127 - _postgres_ expects _source_ to be a space-separated list of _key=value_
128 parameters, e.g. _db postgres "host=/run/postgresql dbname=soju"_. Note
129 that _sslmode_ defaults to _require_. For more information on connection
130 strings, see:
131 <https://pkg.go.dev/github.com/lib/pq#hdr-Connection_String_Parameters>.
132
133*log* fs <path>
134 Path to the bouncer logs root directory, or empty to disable logging. By
135 default, logging is disabled.
136
137*http-origin* <patterns...>
138 List of allowed HTTP origins for WebSocket listeners. The parameters are
139 interpreted as shell patterns, see *glob*(7).
140
141 By default, only the request host is authorized. Use this directive to
142 enable cross-origin WebSockets.
143
144*accept-proxy-ip* <cidr...>
145 Allow the specified IPs to act as a proxy. Proxys have the ability to
146 overwrite the remote and local connection addresses (via the PROXY protocol,
147 the Forwarded HTTP header field defined in RFC 7239 or the X-Forwarded-\*
148 HTTP header fields). The special name "localhost" accepts the loopback
149 addresses 127.0.0.0/8 and ::1/128.
150
151 By default, all IPs are rejected.
152
153*max-user-networks* <limit>
154 Maximum number of networks per user. By default, there is no limit.
155
156*motd* <path>
157 Path to the MOTD file. The bouncer MOTD is sent to clients which aren't
158 bound to a specific network. By default, no MOTD is sent.
159
160*multi-upstream-mode* true|false
161 Globally enable or disable multi-upstream mode. By default, multi-upstream
162 mode is enabled.
163
164*upstream-user-ip* <cidr...>
165 Enable per-user IP addresses. One IPv4 range and/or one IPv6 range can be
166 specified in CIDR notation. One IP address per range will be assigned to
167 each user and will be used as the source address when connecting to an
168 upstream network.
169
170 This can be useful to avoid having the whole bouncer banned from an upstream
171 network because of one malicious user.
172
173# IRC SERVICE
174
175soju exposes an IRC service called *BouncerServ* to manage the bouncer.
176Commands can be sent via regular private messages
177(_/msg BouncerServ <command> [args...]_). Commands may be written in full or
178abbreviated form, for instance *network* can be abbreviated as *net* or just
179*n*.
180
181*help* [command]
182 Show a list of commands. If _command_ is specified, show a help message for
183 the command.
184
185*network create* *-addr* <addr> [options...]
186 Connect to a new network at _addr_. _-addr_ is mandatory.
187
188 _addr_ supports several connection types:
189
190 - _[ircs://]<host>[:port]_ connects with TLS over TCP
191 - _irc+insecure://<host>[:port]_ connects with plain-text TCP
192 - _irc+unix:///<path>_ connects to a Unix socket
193
194 Other options are:
195
196 *-name* <name>
197 Short network name. This will be used instead of _addr_ to refer to the
198 network.
199
200 *-username* <username>
201 Connect with the specified username. By default, the nickname is used.
202
203 *-pass* <pass>
204 Connect with the specified server password.
205
206 *-realname* <realname>
207 Connect with the specified real name. By default, the account's realname
208 is used if set, otherwise the network's nickname is used.
209
210 *-nick* <nickname>
211 Connect with the specified nickname. By default, the account's username
212 is used.
213
214 *-enabled* true|false
215 Enable or disable the network. If the network is disabled, the bouncer
216 won't connect to it. By default, the network is enabled.
217
218 *-connect-command* <command>
219 Send the specified command as a raw IRC message right after connecting
220 to the server. This can be used to identify to an account when the
221 server doesn't support SASL.
222
223 For instance, to identify with _NickServ_, the following command can be
224 used:
225
226 ```
227 PRIVMSG NickServ :IDENTIFY <password>
228 ```
229
230 The flag can be specified multiple times to send multiple IRC messages.
231 To clear all commands, set it to the empty string.
232
233*network update* <name> [options...]
234 Update an existing network. The options are the same as the
235 _network create_ command.
236
237 When this command is executed, soju will disconnect and re-connect to the
238 network.
239
240*network delete* <name>
241 Disconnect and delete a network.
242
243*network quote* <name> <command>
244 Send a raw IRC line as-is to a network.
245
246*network status*
247 Show a list of saved networks and their current status.
248
249*channel status* [options...]
250 Show a list of saved channels and their current status.
251
252 Options:
253
254 *-network* <name>
255 Only show channels for the specified network. By default, only the
256 channels in the current network are displayed.
257
258*channel update* <name> [options...]
259 Update the options of an existing channel.
260
261 Options are:
262
263 *-relay-detached* <mode>
264 Set when to relay messages from detached channels to the user with a BouncerServ NOTICE.
265
266 Modes are:
267

270
271 *highlight*
272 Relay only messages mentioning you when detached.
273
274 *none*
275 Don't relay any messages from this channel when detached.
276
277 *default*
278 Currently same as *highlight*. This is the default behaviour.
279
280 *-reattach-on* <mode>
281 Set when to automatically reattach to detached channels.
282
283 Modes are:
284
285 *message*

298 Automatically detach this channel after the specified duration has elapsed without receving any message corresponding to *-detach-on*.
299
300 Example duration values: *1h30m*, *30s*, *2.5h*.
301
302 Setting this value to 0 will disable this behaviour, i.e. this channel will never be automatically detached. This is the default behaviour.
303
304 *-detach-on* <mode>
305 Set when to reset the auto-detach timer used by *-detach-after*, causing it to wait again for the auto-detach duration timer before detaching.
306 Joining, reattaching, sending a message, or changing any channel option will reset the timer, in addition to the messages specified by the mode.
307
308 Modes are:
309
310 *message*
311 Receiving any message from this channel will reset the auto-detach timer.
312
313 *highlight*
314 Receiving any message mentioning you from this channel will reset the auto-detach timer.
