iptables cannot open ports. It can filter them (which is probably what you mean by "stealthed"), but a port only become open if there's a program listening on that port. You need to start a server daemon (sshd, apache, or whatever) configured to listen on the unfiltered port for it to appear as "open" in an nmap scan. -- Brad Beyenhof . . . . . . . . . . . . . . . . . http://augmentedfourth.com Life would be so much easier if only (3/2)^12=(2/1)^7. -- [email protected] http://www.kernel-panic.org/cgi-bin/mailman/listinfo/kplug-newbie
