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.
