got confused with the iptables settings !! Please clarify me !


Hi All

In my server the iptables and ip6tables services are not running. But still i am getting some iptables and ip6tables related alerts on my /var/log/messages. My technical leader told me that there might be some mis-configuration in iptables configuration file. But i didnt see anything wrong.

Hi,

Which distro you are using?
If you are not using avahi daemon then try stopping the service and then check if it resolves the problem.

i am using rhel 5.3 32 bit. i am checking actually what avahi daemon is doing, if it would not create any further issues, then i will disable and check the same.
