iptables question
 

Hi Guys,how can i check whether iptables is running in my machine. I mean which is the daemon for iptables ?

Someone correct me if I'm wrong, but iptables is effectively a part of the kernel, so you don't check if it's running as such, you just check what rules are in place (iptables -L).

Additionally, iptables loads modules, but these aren't daemons.

There is a kernel module called ip_tables.
You can enter iptables-save to dump out the rules.
