My hostname at the shell prompt initialy was "unknown0011b5dd0e7e"
I changed it to "MyHostname" through Administration->Network->DNS-Hostname.
Now the prompt correctly displays "MyHostname" but on my Billion router DHCP Table it says "unknown0011b5dd0e7e" running in windows is correct.
I am wondering if this is causing my problems with Samba? Can someone tell me whats going on?
