How 2 get Debian to broadcast its host name to my router?

I have a router and when my Debian machine connects I get "null" as the host name. How can I get it to display the host name?

How does your Debian get its IP addresses?

nimnull22, from the router DHCP

What dhcp client is used?

lindylex · 12-04-2009, 08:49 PM

I am not sure how do I check?

I have /sbin/dhclient and /sbin/dhclient3

Good.

Then you have to have somewhere dhclient.conf. Probably in /etc/dhcp3/dhclient.conf.

Find "dhclient.conf" and add there: send host-name "YOUR HOST NAME" ( send host-name "xxx.xxx.com")

And dhclient should send it to router each time it asks for IP.

You can check "man dhclient.conf", because I've read about it, but never use.

But this won't be BROADCAST.

nimnull22, thanks that is exactly what i did.

1. I edited this file /etc/dhcp3/dhclient.conf by looking for this line "send host-name", adding it or removing the comment "#" from in front of it.

2. I changed it to the following and my Belkin router can see it's name.

send host-name "myrouterwilldisplaythisname";

Thanks for the help.

Yes, but does it work?
Does your router cache your hostname?

It worked I rebooted the computer two times changed the names both times to check and it worked.

Good.
