Any Ubuntu system that connects to my router (Netgear Super Wireless ADSL Router DG834GT) does not acquire a host name on the network. The router reports the IP, and "unknown" as the "device name". As a consequence, the PC can only be reached over the intranet using an ip address, not using a hostname.
My mybookworld network drive, that also runs a flavour of linux, does appear to my router with the name "networkspace". This must therefore be a network configuration issue of Ubuntu.
I have a hostname set in my Ubuntu system.
What could I adjust in my Ubuntu configuration such that also Ubuntu systems acquire a hostname in the router, working as a DCHP server?
vanadium@vanadium:~$ hostname -a
vanadium@vanadium:~$ hostname --fqdn
vanadium@vanadium:~$ cat /etc/hosts
127.0.0.1 localhost.localdomain localhost vanadium
# The following lines are desirable for IPv6 capable hosts
