	15 IRC. Remember to strip input for example with tr(1), tr -cd "0-9a-zA-Z" …

	26 stats this will also work if you choose the irssi log format.

	28 Automatic reconnects

	31 like this in a shell script:

	46 [iibot](https://github.com/c00kiemon5ter/iibot) by c00kiemon5ter is writ…
	47 bash, but can easily be translated to plain sh (ask him).
	48
	49 It uses a main script to connect to multiple servers and channels, and
	50 auto-reconnect and auto-join on network failure.
	51
	52 It reads commands with a leading '!' and calls a secondary script to han…
	53 command and the responce. That way commands can be added or removed
	54 dynamically. The secondary script knows the network, channel, nick and m…
	55 that triggered the command, so it is easy to filter responses to command…
	56 specified channels, users and such.

	60 nagios
	61 ------
	62 Simple Perl script "nagios\_post.pl" as interface between
	63 [Nagios](http://www.nagios.org/) and ii:
	64
	65 #!/usr/bin/perl -w
	66
	67 my $users = "your_nickname(s)";
	68 my $pipe = "$ENV{HOME}/irc/your_irc_server/#your_channel/in";
	69 my %color = (
	70 red => "\0034",
	71 purple => "\0036",
	72 yellow => "\0038",
	73 clear => "\00315",
	74 blue => "\0032\002",
	75 green => "\0033",
	76 normal => "\0031",
	77 );
	78
	79 open(PIPE, '>', $pipe) or die "Can't write to $pipe: $!";
	80 while (<>) {
	81 s/Host [a-z0-9_.]+ is down/$color{red}$&$color{normal}/i;
	82 s/PROBLEM.*?CRITICAL/$color{red}$&$color{normal}/i;
	83
	84 s/PROBLEM.*?WARNING/$color{yellow}$&$color{normal}/i;
	85 s/Host [a-z0-9_.]+ is up/$color{green}$&$color{normal}/i;
	86
	87 s/RECOVERY.*?OK/$color{green}$&$color{normal}/i;
	88
	89 print PIPE "$users: $_";
	90 }
	91 close(PIPE);
	92
	93 The appropriate Nagios configuration looks like this:
	94
	95 # 'notify-by-irc' command definition
	96 define command{
	97 command_name notify-by-irc
	98 command_line /usr/bin/printf "%b" "$TIME$ $NOTIFICATI…
	99 }
	100
	101 # 'host-notify-by-irc' command-notification
	102 define command{
	103 command_name host-notify-by-irc
	104 command_line /usr/bin/printf "%b" "$TIME$ Host $HOSTA…
	105 }
	106
	107 Start ii appropriately and add notify-by-irc and host-notify-by-irc to t…

	111 rsstail

	113 Just piping the output of [rsstail](http://www.vanheusden.com/rsstail/) …
	114 the fifo "in" should work. More detailed examples are welcome.
