Blank/empty hostname

Question

I am using Ubuntu 12.10 and i was wondering if there is way to not send my hostname when connecting to a router? For example when I connect to my router I can see my laptop hostname when I log on the router, under "DHCP Leases".

I dont want to change my hostname, I would just like to not send anything so that under "Hostname" in my router my laptop mac address appears with no name. Is that possible? I have noticed sometimes that blank hostnames do appear for some connected devices.

Edit: I am aware of this How can I stop sending my hostname via DHCP? however it does not seem to work under ubuntu 12.10.

Answer 1

You forgot to tell us if you are running Ubuntu, and what version.

On my Ubuntu 13.10, I'd have to edit /etc/dhcp/dhclient.conf and comment the following line:

send host-name = gethostname();

"Commenting" a line is just putting an # before it, so it would look like this:

#send host-name = gethostname();
