no logs for iptables

I had to install Arch again, but noticed soon one "fail", no firewall logs in /var/log/ no iptables, no firewall nothing. I use Arno's iptables configuring tool for my iptables. but there has been earlier iptables logs available. how to get them back

Re: no logs for iptables

Are there any LOG jump targets defined in your rules?

What is the output of `iptables -nvL` (as root)

Re: no logs for iptables

Looks good too... And /var/log/iptables.log is definitely empty?

I didn't think to check before, but all the LOG targets in your rules have 0 hits against them, so traffic has matched the logging rules so this may explain why nothing is logging smile

Try adding this rule in for testing:

iptables -I OUTPUT -m state --state NEW -j LOG

(Thanks for wrapping the rules output in code tags too btw smile)
