| 11 | # DESCRIPTION
|
|---|
| 12 |
|
|---|
| 13 | suika is a user-friendly IRC bouncer. It connects to upstream IRC servers on
|
|---|
| 14 | behalf 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 |
|
|---|
| 23 | When joining a channel, the channel will be saved and automatically joined on
|
|---|
| 24 | the next connection. When registering or authenticating with NickServ, the
|
|---|
| 25 | credentials will be saved and automatically used on the next connection if the
|
|---|
| 26 | server supports SASL. When parting a channel with the reason "detach", the
|
|---|
| 27 | channel will be detached instead of being left.
|
|---|
| 28 |
|
|---|
| 29 | When all clients are disconnected from the bouncer, the user is automatically
|
|---|
| 30 | marked as away.
|
|---|
| 31 |
|
|---|
| 32 | suika 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 |
|
|---|
| 44 | For per-client history to work, clients need to indicate their name. This can
|
|---|
| 45 | be done by adding a "@<client>" suffix to the username.
|
|---|
| 46 |
|
|---|
| 47 | suika will reload the configuration file, the TLS certificate/key and the MOTD
|
|---|
| 48 | file when it receives the HUP signal. The configuration options _listen_, _db_
|
|---|
| 49 | and _log_ cannot be reloaded.
|
|---|
| 50 |
|
|---|
| 51 | Administrators can broadcast a message to all bouncer users via _/notice
|
|---|
| 52 | $<hostname> <text>_, or via _/notice $\* <text>_ in multi-upstream mode. All
|
|---|
| 53 | currently connected bouncer users will receive the message from the special
|
|---|
| 54 | _BouncerServ_ service.
|
|---|
| 55 |
|

| 73 | The config file has one directive per line.
|
|---|
| 74 |
|
|---|
| 75 | Example:
|
|---|
| 76 |

| 78 | listen ircs://
|
|---|
| 79 | tls cert.pem key.pem
|
|---|
| 80 | hostname example.org
|
|---|
| 81 | ```
|
|---|
| 82 |
|
|---|
| 83 | The 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, suika 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 "./suika.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=suika"_. 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 |
|
|---|
| 175 | suika exposes an IRC service called *BouncerServ* to manage the bouncer.
|
|---|
| 176 | Commands can be sent via regular private messages
|
|---|
| 177 | (_/msg BouncerServ <command> [args...]_). Commands may be written in full or
|
|---|
| 178 | abbreviated 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 | For example, to connect to Libera Chat:
|
|---|
| 195 |
|
|---|
| 196 | ```
|
|---|
| 197 | net create -addr irc.libera.chat
|
|---|
| 198 | ```
|
|---|
| 199 |
|
|---|
| 200 | Other options are:
|
|---|
| 201 |
|
|---|
| 202 | *-name* <name>
|
|---|
| 203 | Short network name. This will be used instead of _addr_ to refer to the
|
|---|
| 204 | network.
|
|---|
| 205 |
|
|---|
| 206 | *-username* <username>
|
|---|
| 207 | Connect with the specified username. By default, the nickname is used.
|
|---|
| 208 |
|
|---|
| 209 | *-pass* <pass>
|
|---|
| 210 | Connect with the specified server password.
|
|---|
| 211 |
|
|---|
| 212 | *-realname* <realname>
|
|---|
| 213 | Connect with the specified real name. By default, the account's realname
|
|---|
| 214 | is used if set, otherwise the network's nickname is used.
|
|---|
| 215 |
|
|---|
| 216 | *-nick* <nickname>
|
|---|
| 217 | Connect with the specified nickname. By default, the account's username
|
|---|
| 218 | is used.
|
|---|
| 219 |
|
|---|
| 220 | *-enabled* true|false
|
|---|
| 221 | Enable or disable the network. If the network is disabled, the bouncer
|
|---|
| 222 | won't connect to it. By default, the network is enabled.
|
|---|
| 223 |
|
|---|
| 224 | *-connect-command* <command>
|
|---|
| 225 | Send the specified command as a raw IRC message right after connecting
|
|---|
| 226 | to the server. This can be used to identify to an account when the
|
|---|
| 227 | server doesn't support SASL.
|
|---|
| 228 |
|
|---|
| 229 | For instance, to identify with _NickServ_, the following command can be
|
|---|
| 230 | used:
|
|---|
| 231 |
|
|---|
| 232 | ```
|
|---|
| 233 | PRIVMSG NickServ :IDENTIFY <password>
|
|---|
| 234 | ```
|
|---|
| 235 |
|
|---|
| 236 | The flag can be specified multiple times to send multiple IRC messages.
|
|---|
| 237 | To clear all commands, set it to the empty string.
|
|---|
| 238 |
|
|---|
| 239 | *network update* [name] [options...]
|
|---|
| 240 | Update an existing network. The options are the same as the
|
|---|
| 241 | _network create_ command.

|---|
| 242 |
|
|---|
| 243 | When this command is executed, suika will disconnect and re-connect to the
|
|---|
| 244 | network.
|
|---|
| 245 |

| 252 |
|
|---|
| 253 | *network quote* [name] <command>
|
|---|
| 254 | Send a raw IRC line as-is to a network.
|
|---|
| 255 |
|
|---|
