Illegal argument on owner match

I have iptables 1.2.11 on Debian Woody.
I am not able to issue an option "-m owner --gid-owner 1234".
On the same box, this option worked until yesterday, today - as usual -
I performed an update of the existing packages.

The ipt_owner module seem installed, modprobe doesn't issue any error,
trying:

iptables -m owner -h

lists correctly the options.

I found the message below: maybe the problem is in userspace syncing,
but I don't know how to do it.

Can anybody help ?

Thanks,

Massimo

Look if you have this file:
/lib/iptables/libipt_owner.so

or do:
iptables -m owner -h


to see if you've got the support for owner.


If you have the support then probably the userspace code
from iptables and the kernel code it's not synced.
