[[https://www.bitlbee.org/|Bitlbee]] helps act as a bridge from IRC to [[a variety of other protocols|https://wiki.bitlbee.org/]]. For example, you can use Bitlbee to connect IRC to Telegram, Discord, or Slack. The core of bitlbee itself is written in C.

First, let's install the package:

<code>
$ doas pkg_add bitlbee-3.6p0-libpurple
</code>

The developers suggest not installing bitlbee-3.6p0-libpurple-otr if you plan to provide a public bitlbee instance. This is because the encryption provided by [[https://otr.cypherpunks.ca/|OTR]] (Off-the-Record) is undermined by the fact that the sysadmin can intercept the messages in plaintext. It gives a false sense of security. Moreover, OTR messaging is often broken when the same account is used with other XMPP clients besides bitlbee.

Edit /etc/bitlbee/bitlbee.conf:

<code>
RunMode = ForkDaemon
User = _bitlbee
# Bitlbee will only be bound to localhost on port 6668
DaemonInterface = 127.0.0.1
DaemonPort = 6668
OperPassword = pass123
AllowAccountAdd 1
HostName = example.com
</code>

Replace pass123 with your own password. We set bitlbee to be bound to localhost on port 6668, which users of [[openbsd:irc:znc|our bouncer]] will be able to connect to.

To start bitlbee:

<code>
$ doas rcctl enable bitlbee
$ doas rcctl start bitlbee
</code>
