Thanks Damian … I have updated the post.

Thanks for this!

When creating the backup, you have …/dhcp/… instead of …/dhcp3/… as the destination.

Also, Brian’s tip about using host-name “” didn’t work for me on Xubuntu Hardy.

You wrote:
test if other machines on the network can now look up your machine by using the FQDN.

Here is my /etc/hosts:

bruparel@bcr-d810:/etc$ cat hosts
127.0.0.1 localhost
127.0.1.1 bcr-d810

If I try to ping bcr-d810 it does not find it. Here is the changed in /etc/dhcp3/dhclient.conf:

send host-name “bcr-d810″;
#send dhcp-client-identifier 1:0:a0:24:ab:fb:9c;

I restart the computer, but I can’t seem to be able to ping bcr-d810. What do I have to do to set a proper FQDN?

Thanks.

There’s a cleaner way to do this.

Ubuntu has a built in variable for the hostname. Instead of saying:

send host-name “ubuntu-laptop”;

you can say:

send host-name “”;

This way, if you decide to change your hostname, you only have to update one place.

HTH,
Brian

Thanks Tom good catch. I have updated the post to fix the error.

Thanks for your tip!

One thing I noticed:

The send host-name command needed a semi-colon at the end of the line before it worked for me.

This works on Debian 4 too.
