check if firewall is on without any package like iptables


On Linux, is there any command/logfile to confirm that the firewall is enabled without the use of the iptables or any such package that needs to be installed.


I just want to know if there is a default logfile/command for linux that can tell me if firewall is enabled or present? For example, use of netfilter?
Thanks

That's easy; if you don't have iptables installed, you don't have the tools required to set up netfilter, so I'm pretty sure it can't be active.

That said, you could try looking under /proc/sys/net/netfilter or /proc/net/netfilter - although I don't see how you can get much useful information out of the conntrack state that's exposed there.
