Hello everyone I have successfully built a bridge/firewall with the iptables and brctl utilities. I now want to build in some fancy protection against portscans, trojans and krap like that. Does anyone know, or would like to share, where i can find info on common ports used by trojans like back-orifice, and the some tcp flags used by portscanners, like syn,rst rst,syn ect .. thanks regards CilliƩ
