Please avoid top-posting and quoting the full previous mail.
I asked for whether running phpBB because there are worms which use a
weakness of this forum application. It is a trojan and establishes an
irc connection. I don't know if some worm versions use bash, I heard of
those using Perl.
Well, you have the PID of the suspicious connections to irc server (you
can connect to the listed IPs using telnet to see they are really
running an ircd) and locate where they are coming from, who owns these
PIDs. I would worry for these connections. Although you gave too less
information to be serious about what it means. So you didn't say whether
you have users on the host in question which could use specific
programs. At least bash to irc servers seem very uncommon to me.
