3. Started: 2008-06-20

use IO::Socket; use IO::Select;

$user = 'odserver'; $pass = '********'; $channel = '#organicdesign';

$sock = IO::Socket::INET->new( PeerAddr => 'irc.freenode.net', PeerPort => 6667, Proto => 'tcp' ) or die "could not make the connection";

while (<$sock>) { if (/(NOTICE AUTH).*(checking ident)/i) { print $sock "NICK $user\nUSER $user 0 0 :odbot.pl\n"; last; } }

while (<$sock>) {

# if the server asks for a ping print $sock "PONG :".(split(/ :/, $_))[1] if /^PING/;

# end of MOTD section if (/ (376|422) /) { print $sock "NICKSERV :identify $user $pass\n"; last; } }

1. Wait for a few secs and join the channel

sleep 3; print $sock "JOIN $channel\n";

1. Main channel activity oop
