'Host name' on router status page...

[buccaneere]

One of my computers no longer identifies itself by the host name that it used to ...

It now shows 'unknown', where it used to show 'chucknb-desktop'

Host Name IP Address MAC Address Expired Time

unknown 192.168.0.103 00-14-78-ed-a5-b7 Apr/07/2009 22:40:36

Any ideas?

I think your host name is set by the file /etc/hosts on most systems - it should say something like

127.0.0.1 chucknb-desktop localhost

Well, you're right, and my machine is still wrong.

??? Do I need to edit the entry? ADD an entry?

/etc/hosts
127.0.0.1 localhost
127.0.1.1 chucknb-desktop

# The following lines are desirable for IPv6 capable hosts
::1 ip6-localhost ip6-loopback
fe00::0 ip6-localnet
ff00::0 ip6-mcastprefix
ff02::1 ip6-allnodes
ff02::2 ip6-allrouters
ff02::3 ip6-allhosts

Actually it's /etc/hostname that sets your host name.

Also check the manpage for the hostname command.

/etc/hosts associates host names with IP addresses.
