Firewall: receiving common error message for IPTABLES under Mandrake 8.1
 

I'm trying to rebuild my firewall in the wake of a hard drive death.

New HD, fresh installation of Drake 8.1 (with Ximian Red Carpet updates); using Gnome.

When I try to build a new firewall (as su root) with either Bastille or Firestarter, I get the following error message(s):

Gnome-UI warning **: While connecting to session manager:
Authentication rejected, reason: None of the authentication protocols specified are supported and host-based authentication failed.
NETFILTER detected
Using /lib/modules/2.4.8-26mdk/kernel/net/ipv4/netfilter/ip_tables.o.gz
Insmod: a module named ip_tables already exists

What authentication protocols are at issue here?

I searched for any file named ip_tables (recursively, from /) and found nothing. Why would insmod have reported this and how can I fix it?

*It should be noted that either Bastille or Firestarter still run after these error messages are generated, but their finished results generate a lot of other error messages when the firewall is activated.

Thanks!

If a find in your current kernel modules dir like "find /lib/modules/$(uname -r) -name ip_tables* -print" returns an ip_tables.o, and lsmod show ip_tables loaded and the firewall script works then all these messages prolly are bogus.
