Fix hostname “Unknown” in router February 6, 2006

Posted by Carthik in snippets, ubuntu.

I have a D-link router, and have three ubuntu boxes at home. When I got the router management page and look at the DHCP clients that are connected to the router, I see either “unknown” or ” ” as the name for the Ubuntu boxes. Managing these becomes a pain, as i have to resort to finding out the MAC address to do this.

The WinXP boxes have their designated names.

The hostname for the Ubuntu boxes are set, and yet the router recognizes them as “unknown” or ” “.

I fixed this problem by editing the /etc/dhcp3/dhclient.conf file to uncomment the following line and editing it as follows:
send host-name "gabriel"

This actually fixed my ADS system that I have setup at the office. It wasn’t reporting a valid anme, so the DNS server would assign it an arbitrary one.

When I found this, I used the tip, and the DNS now assigns it the name requested.

Many thanks for this tip. I’ve only just installed Xubuntu after using Mandrake/Mandriva for three years, which does this sort of thing a little bit different, so was wondering how to fix this. Now looking at it, it seems so obvious. Thanks for resolving it.

Thanks! That gives me a Host Name on my
router. But my Domain Name still shows up
as “unknown”. Any magic for that???
