Hi all, Probably asked a few times on this list but don't shoot me. I have the SuSEfirewall up and running and closed everything FW_SERVICES_EXTERNAL_TCP & UDP = "" and also INCOMING_HIGHPORTS_TCP & UDP = "". A portscan (nmap) however reveals that all the upd ports are open! Is this a risk or not and how are these closed with the help of the script? Thank you, -Peter-

You can check the firewall rules with ipchains -nvL|less (use a large xterm :)) Did you used nmap against localhost? It's not uncommon to open localhost and loopbackdevice. Of couse you have to scan from outside your network. oki, Steffen -- Dieses Schreiben wurde maschinell erstellt, es trägt daher weder Unterschrift noch Siegel.
