Description James Ralston 2002-08-26 01:43:36 EDT
Description of Problem:

The "dhclient" DHCP client program seems to always set the hostname of the
machine on which it is run to whatever value is returned by the DHCP server.

If there is a way to inhibit this behavior, I haven't found it.

For example, here is my /etc/sysconfig/network file:

    NETWORKING=yes
    HOSTNAME=farslayer.l33tskillz.org

Here is my /etc/hosts file:

    # Do not remove the following line, or various programs
    # that require network functionality will fail.
    127.0.0.1       localhost       localhost.localdomain

My hostname:

    $ hostname
    farslayer.l33tskillz.org

When dhclient runs, it changes the hostname to whatever value the DHCP server
returns.  This is bogus.

Version-Release number of selected component (if applicable):

dhclient-3.0pl1-7

How Reproducible:

Run dhclient.

The "right" solution is to fix your DHCP server to send back the correct hostname...

But an option may be added, we'll see.
