The SMB name for a machine does not have to match the host name. The name you give in the Samba configuration file is the one that you use when browsing shares. Now, if you want to do tie SMB names to addresses, that is what the lmhosts file is for. (/etc/samba/lmhosts and c:\windows\lmhosts are the normal files used.) > Do you mean adding a line for the local host addresses to the hosts > file?

And it has to be an IP address that the machine responds to. So you can not give it an IP address like 127.0.0.2 unless you create a second interface like lo:1 that responds to that IP address. One of problems is home networks connected to a firewall/router using DHCP. A lot of them handle DHCP, and act as a caching name server for the local network, but they do not DHCP lease to hostname mapping. So you can not ask the name server for the IP address for your hostname. Now, if you can configure the DHCP server so that you always get the same hostname, you can put that entry in your /etc/hosts file and be all set. A better solution might be to add an option to the DHCP client so that it can add/remove a /etc/hosts entry for your hostname that matches the IP address assigned to the interface. You would need to be able to control it on an individual interface option. (I have not looked into this - do any of the DHCP clients support this?)
