iptables problem



Dear all,

I am running Sarge and recently the kernel was updated by "apt-get update/upgrade". (Although it still shows the same version:

debian[~]% uname -a
Linux debian 2.6.8-2-k7 #1 Mon Jan 24 03:29:52 EST 2005 i686 GNU/Linux

And that's what I had before. It's always been a stock debian kernel installed via apt-get. The installation process told me that I needed to reboot ASAP for the correct modules to be loaded, which I did as soon as installation was over.)

After that iptables is not working anymore. Here is a the errors that I get:

root[~]$ iptables.sh
WARNING: Error inserting ip_conntrack (/lib/modules/2.6.8-2-k7/kernel/net/ipv4/netfilter/ip_conntrack.ko): Unknown symbol in module, or unknown parameter (see dmesg) FATAL: Error inserting ip_conntrack_ftp (/lib/modules/2.6.8-2-k7/kernel/net/ipv4/netfilter/ip_conntrack_ftp.ko): Unknown symbol in module, or unknown parameter (see dmesg)
iptables: No chain/target/match by that name

In dmesg, I get:

I also tried

root[~]$ modprobe ip_conntrack
FATAL: Error inserting ip_conntrack (/lib/modules/2.6.8-2-k7/kernel/net/ipv4/netfilter/ip_conntrack.ko): Unknown symbol in module, or unknown parameter (see dmesg)

Dmesg again:

(...)

ipt_state: Unknown symbol ip_conntrack_get
ipt_state: Unknown symbol need_ip_conntrack
ip_conntrack: Unknown symbol ipfrag_flush


And I cannot connect to the iternet until I "/etc/init.d/iptables clear".

Any suggestions would be greatly appreciated.  (Google did not help...)

Best to all,

Luis
