I know how do this with PF. Don't have any idea with iptables. :( Ong Chin Kiat wrote:
Hi list, I've recently used an SSH server that had an interesting authentication mechanism. You first had to telnet to the machine on a certain port. After doing this (it will just time out - no prompt), you then SSH to the server in question. The telnet step has to be carried out, if not SSH will just time out. My question is, is this called reflexive firewalling, and can I duplicate this with iptables? Thanks.
