Couple of questions. 1. I want to log all activity on a certain port, 8476, for example. So I used these iptables matches: Code: iptables -A INPUT -p tcp --dport 8476 -j LOG --log-level info iptables -A INPUT -p udp --dport 8476 -j LOG --log-level info However, it doesn't seem to be logging. Is there something obvious I'm missing? Can anybody provide some insight? 2. I seem to have a slight problem with lingering connections. I logged into my server from work the other day at about 11am. I logged out before I left work at 12n (noon), and then logged back in again from home later in the evening (about 6pm). I checked /proc/net/ip_conntrack to see what kind of traffic I had going, and it showed that my SSH connection (port 22) from work earlier was still active. Anybody know what could be causing that?
