Hey all- My apologies if I am rehashing a previous topic, but I didn't find it in the archives.
I recently setup a linux firewall using iptables and then ran an nmap against the host. Nmap reported a few ports, all of them "filtered" instead of open. As I understand it, this means that nmap is not sure if the port is open or not, because it is not getting any return packets. Is there a way to use iptables to "stealth" the port? In other words, can iptables be configured in such a way as to make port scanners think that a port (or a host!) does not even exist at the specified ip? Would adding a filter against icmp be enough (since nmap pings for hosts first... unless told not to)? - J _______________________________________________ Firewalls mailing list [EMAIL PROTECTED] http://lists.gnac.net/mailman/listinfo/firewalls
