## mod_irc
This module is an IRC transport that can be used to join channels on IRC
servers.
End user information:
- A XMPP client with groupchat 1.0 support or Multi-User Chat
support ([`XEP-0045`][72]) is
necessary to join IRC channels.
- An IRC channel can be joined in nearly the same way as joining a
XMPP Multi-User Chat room. The difference is that the room name will
be channel%`irc.example.org` in case `irc.example.org` is the IRC
server hosting channel. And of course the host should point to the
IRC transport instead of the Multi-User Chat service.
- You can register your nickame by sending IDENTIFY password to
`nickserver!irc.example.org@irc.jabberserver.org`.
- Entering your password is possible by sending LOGIN nick
password
to `nickserver!irc.example.org@irc.jabberserver.org`.
- The IRC transport provides Ad-Hoc Commands
([`XEP-0050`][73]) to join a
channel, and to set custom IRC username and encoding.
- When using a popular XMPP server, it can occur that no connection
can be achieved with some IRC servers because they limit the number
of connections from one IP.
Options:
**`host: HostName`**: This option defines the Jabber ID of the service. If the `host`
option is not specified, the Jabber ID will be the hostname of the
virtual host with the prefix `irc.`. The keyword “@HOST@” is
replaced at start time with the real virtual host name.
**`db_type: mnesia|sql|riak`**: Define the type of storage where the module will create the tables and store user information. The default is the storage defined by the global option `default_db`, or `mnesia` if omitted. If `sql` or `riak` value is defined, make sure you have defined the database, see [database](#database-and-ldap-configuration).
**`access: AccessName`**: This option can be used to specify who may use the IRC transport
(default value: `all`).
**`default_encoding: Encoding`**: Set the default IRC encoding. Default value: `iso8859-1`
Examples:
- In the first example, the IRC transport is available on (all) your
virtual host(s) with the prefix `irc.`. Furthermore, anyone is
able to use the transport. The default encoding is set to
“iso8859-15”.
modules:
...
mod_irc:
access: all
default_encoding: "iso8859-15"

- In next example the IRC transport is available with JIDs with prefix
`irc-t.net`. Moreover, the transport is only accessible to two users
of `example.org`, and any user of `example.com`:
acl:
paying_customers:
user:
- "customer1": "example.org"
- "customer2": "example.org"
server: "example.com"
access_rules:
irc_users:
- allow: paying_customers
