Subject: newbie question: log all packets to closed ports?
Date: Mon, 16 Mar 2009 23:02:28 -0700 (PDT) [thread overview]
Message-ID: <499103.50011.qm@web81807.mail.mud.yahoo.com> (raw)
I just tried iptables on my Linux box. It's working great. Now I want to use it to log any incoming TCP/UDP packets to any closed ports (not binded to any socket). How should I write the rules?
The server applications running on my Linux box are VOIP related and have TCP/UDP ports dynamically opened and closed. Is it possible to write some simple iptables rules to monitor those unwanted incoming packets destined to all the closed ports?
Thanks!
