[SOLVED] How to change the hostname at the end of pxe unattended installation on Debian

permalac · 11-03-2009, 05:43 AM

Hello,

I just installed a pxe server, and i'm installing debian with pxe . completely unattended with preseeding.

Now, all my installations come with the same hostname, how I can change the hostname to something different?

Thanks.

Hi,

Change to show the correct hostname in

Code:

/etc/hostname
/etc/hosts

Of course if you have other services configured, like apache or something, where the hostname is used then you'll have to change accordingly in those config files.

Kind regards,

Eric

The thing is that they come from a pxe unattended installation.

I was expecting a way to make it unattended, using the preseeding standard, if there is such thing.

thanks.

Ok, got it now

Not familiar with the whole PXE booting. Sorry.

But you tried to help, very kind from your part. Thanks.

If one day you need to install several machines , or the same machine several times, i suggest you to try pxe installation.

answer from serverfault:

One simple way that comes to mind without setting up things in DHCP.

Assuming there is a web site you can add files to. Place the hostname inside a file based on the Mac. Then retrieve it with wget.

e.g.:

mac=`ifconfig eth0 | grep HWaddr | sed 's/^.*HWaddr //; s/://g'`
wget -O hostname.txt http://www.example.com/$mac
hostname `cat hostname.txt`

The mac file name would be in lower case with no colon (

characters.
