I cannot reproduce the problem described.  Calling 
'modprobe ip_conntrack_irc ports=1,2,3,4,5,6,7,8,9' gives the correct
error:

/lib/modules/2.4.20/kernel/net/ipv4/netfilter/ip_conntrack_irc.o: too many
values for ports (max 8)

The ip_conntrack_irc code tells the core kernel module system that it supports a
'ports' parameter with up to eight integer values.  Everything else is
dealt
with by the module loader.

Can you plase indicate what exact version of the linux kernel you are using, and
what version of modutils (rpm -q modutils), and what kind of output/error
messages you receive if you try to manually load ip_conntrack_irc with more than
8 ports?

Apologies for the delay. I have been on the road.

Linux bc190110.bendcable.com 2.4.18-19.8.0 #1 Thu Dec 12 04:37:40 EST 2002 i686
athlon i386 GNU/Linux

modutils-2.4.18-2

The statement:'modprobe ip_conntrack_irc
ports=6660,6661,6662,6663,6664,6665,6666,6667,6669,7000,7777,8000,9000' did
not
give any error I could find. This is RH 8.0

This seems to be a RH8 specific issue.  I have several versions of Debian
(sid/woody), Conectiva Linux 7.0 and RH6.2 systems running connection tracking.
 Even with old (<2.4.18) kernels, it works:

[root@lara /root]# cat /etc/redhat-release 
Red Hat Linux release 6.2 (Zoot)
[root@lara /root]# uname -r
2.4.17-pre8-nfpom
[root@lara /root]# rmmod ip_conntrack_irc
[root@lara /root]# modprobe ip_conntrack_irc
ports=6660,6661,6662,6663,6664,6665,6666,6667,6669,7000,7777,8000,9000
/lib/modules/2.4.17-pre8-nfpom/kernel/net/ipv4/netfilter/ip_conntrack_irc.o: too
many values for ports (max 8)

This looks like a problem in either RH8 kernel or modutils.  Please report this
issue to the RedHat bugtracking system.
