1 Bots 2 ==== 3 Its very easy to write shell script based bots with ii. As a short example look 4 at this: 5 6 tail -f \#<CHANNEL>/out | 7 while read -r date time nick mesg; do 8 nick="${nick#<}" 9 nick="${nick%>}" 10 printf "%s: WHAT??\n" "$nick" 11 done >#<CHANNEL>/in 12 13 Its just spamming a channel but I guess your imagination is boundless. I also 14 heard about people using it together with nagios to get the notifications into 15 IRC. Remember to strip input for example with tr(1), tr -cd "0-9a-zA-Z" for 16 example would only allow numbers and characters. 17 18 If you want to see a live demonstration of a bot written for ii, join #grml on 19 freenode, the grml-tips bot which searches for [grml](http://www.grml.org) tips 20 and gives a link or error messages is written in 45 lines of /bin/sh. No, I 21 will not publish the code since I really suck in shell programming :) 22 23 Stat scripts 24 ------------ 25 If you want to use for example [pisg](http://pisg.sf.net/) to generate channel 26 stats this will also work if you choose the irssi log format. 27 28 Automatic reconnects 29 -------------------- 30 If you want some kind of automatic reconnects in ii you can make a something 31 like this in a shell script: 32 33 while true; do 34 ii -s irc.oftc.net -n iifoo -f "John Doe" & 35 iipid="$!" 36 sleep 5 37 printf "/j %s\n" "#ii" > ~/irc/irc.oftc.net/in 38 wait "$iipid" 39 done 40 41 bots for irc it (ii) 42 ==================== 43 44 iibot 45 ----- 46 [iibot](https://github.com/c00kiemon5ter/iibot) by c00kiemon5ter is written in 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 handle the 53 command and the responce. That way commands can be added or removed 54 dynamically. The secondary script knows the network, channel, nick and message 55 that triggered the command, so it is easy to filter responses to commands to 56 specified channels, users and such. 57 58 if you need help, do not hesitate to ask c00kiemon5ter on freenode and oftc. 59 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$ $NOTIFICATIONTYPE$ $HOSTNAME$/$SERVICEDESC$ $SERVICESTATE$ $SERVICEOUTPUT$\n" | /home/nagios/bin/nagios_post.pl 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 $HOSTALIAS$ is $HOSTSTATE$ -- $HOSTOUTPUT$\n" | /home/nagios/bin/nagios_post.pl 105 } 106 107 Start ii appropriately and add notify-by-irc and host-notify-by-irc to the 108 appropriate "service_notification_commands" and 109 "host_notification_commands" -- and you have your own Nagios IRC bot. 110 111 rsstail 112 ------- 113 Just piping the output of [rsstail](http://www.vanheusden.com/rsstail/) into 114 the fifo "in" should work. More detailed examples are welcome.
