Hello again, well, I have had good feedback from SUSE and other users of the Japanese language server, Canna. As far as security at a software level is concerened, I think it is secure. However, it still shows as an open port 5680 when tested with nmap. I have been told that while the software settings are secure, if I want to make it invisible to nmap, I would need kernel level firewalling. I have Firewall2 set up on my dialup ppp box. Can anyone tell me what settings I need to change in YaST to enable firewalling on port 5680 and make it invisible to the outside? I thought that blocking high ports would do it, but it still shows up on nmap. thanks very much This is more a learning process than a real world security threat, but I appreciate your help all the same. cheers Joss
