The local host name is set in /etc/hosts. The syntax is basically this:
IP address host.domain alias
For example:
192.168.0.1 mycomputer.homenetwork mycomputer
There also needs to be an entry for the localhost:
127.0.0.1 localhost
So, the entire thing should look somthing like this:
127.0.0.1 localhost
192.168.0.1 mycomputer.homenetwork mycomputer
Obviously subsitute your own machine info for this....
