Hi,
I am using 2.6.16.13 kernel in smp configuration. Machine is working
as a gateway and frequent iptables commands are fired as users logged in and
logged out.
I got following error in between
[root@manage /root]# iptables -nvx -L INPUT
ERROR: 7 not a valid target)
Aborted (core dumped)
So, I tried to flush INPUT and got following
[root@manage /root]# iptables -F INPUT
iptables: Too many levels of symbolic links
following is a message I got in /var/log/messages
Aug 26 14:38:30 1219741710 kernel: iptables: loop hook 1 pos 0 00000022.
That kernel version has an iptables locking bug that might
lead to corruption. Latest 2.6.16 version has this fixed.
