HI guys , i don`t know if this is the right list , but i could not
find help anywhere else.
I am having a very strange problem with my machine , i can not use
iptables at all.
I have the modules compiled and loaded but i always get :
# iptables -L
iptables v1.3.6: can't initialize iptables table `filter': Bad file descriptor
Perhaps iptables or your kernel needs to be upgraded.
My machine is a ARM machine with debian 4.0.
I also have already tried 1.3.8 and got the same error.
# lsmod
