Hello to all,

I have following question: Can I define a hostname for myself in Linux
when using dhcp?
In our LAN every NT-Station has a Hostname. The DHCP-Server gives this
hostname back if it is not used jet. Is it used then I get 'Hostname-1'.

Thank for helping!

You can do the following if you always assign the same IP address to the
same machine each time:
host blah { hardware ethernet x:x:x:x:x:x; fixed-address x.x.x.x; option
host-name "blah"; }

Not sure how you would generally pool hostnames the way IP addresses
could be pooled.

And how to proceed if the IP is not always the same? (as in my case).

The answer is "yes".  Most of the DHCP server would allow DHCP client
to specify whatever the hostname the client wants and update DNS
properly.  You can read the man page for your DHCP client or tell us
what you use so that we can give you better answer.

Hi Juergen,

another tip from 'de':

as you are from 'de', buy the current german issue (#2) of
'Red Hat Magazin' (EURO 9,95) and read the article on pages 34-39
'Einsatz von DNS und DHCP im privaten Netzwerk' (using
DNS and DHCP in a private network).

It gives information on updating DNS thru DHCP with hostnames
defined by the DHCP clients.

There's also a www.redhatmagazine.com with italian and german
version, but the articles are not on-line.

It's not a command, it's a line that goes in /etc/dhcpd.conf
