Is it possible to block p2p programs using astaro firewall ? If it is, please give some examples on how to do this ? either by ports or iptables ? I'm new in firewalling.....
However Syswatch please keep in mind that IDS is not perfect and the sheer volume of p2p clients/versions etc makes it VERY VERY difficult to keep on top off.
One trick i have found in general is to look at clients traffic logs. P2p programs tend to hog bandwidth at non business hours.
