ip_conntrack_ftp not loading

Hi All,

This is really messing up my passive mode ftp rules.

I am using 64 bit CenOS 5.4 (Red Hat Enterprise Linux clone) and iptables-1.3.5-5.3.el5_4.1

In /etc/sysconfig/iptables-config, I have

IPTABLES_MODULES="ip_conntrack_netbios_ns ip_conntrack_ftp"

Problem:

   # lsmod | grep -i ip_conntrack_ftp

return nothing. ("ip_conntrack_netbios_ns" does not show up either.)

Stopping and starting iptables does not help. Rebooting does not help. In my /etc/rc.d/rc.local, to get ip_conntrack_ftp to show up on lsmod, I had to add:

/sbin/modprobe ip_conntrack_ftp

I do not have this problem on my 32 bit machine.

Is this a bug? and is it time to report it to Red Hat?

Many thanks,
-T
