I ran lsmod and I do not find that ipt_recent is loaded.  In fact, I
don not see any ipt modules other than itp_LOG. There was a recent
kernel update. Does anyone know if this had any adverse effects on
loading ipt_recent?

 .  .  .
ip_tables              17029  3
iptable_nat,iptable_mangle,iptable_filter
ipt_LOG                10049  6
ipv6                  267489  23 ip6t_REJECT
 .  .  .

And this does not look good either:

# modprobe --first-time ipt_recent
FATAL: Error inserting ipt_recent
(/lib/modules/2.6.18-164.9.1.el5/kernel/net/ipv4/netfilter/ipt_recent.ko):
Unknown symbol in module, or unknown parameter (see dmesg)

There is no entry in /var/log/dmesg relating to this problem.
