Thanks Warren. What's bothering me is that I have installed dozens of
Red Hat 8 with DHCP, and the hostname was always localhost.

I was helping one of my partners installing Red Hat 8.0. This is a

I noticed that, instead of the usual "localhost", the computer was
designated, out of the blue, a name called "dhcp-146-41". It was
subsequently concluded that this was the source of all the problems
(including inability to install printer driver, etc.)
If I unplug the cable modem and re-install Red Hat, then everything
would initially appear normal (i.e., it will be given the "localhost"
name). However, as soon as I turn the cable modem back on, the host
name would immediately change to "dhcp-146-41". And during booting
or re-booting, the system would try to load sendmail and samba
server, both of which were never installed. There are also other
problems, including the messages of "cannot find server address
dhcp-146-41" and "this system is controlled by another computer),
etc. If I do the installation with cable modem on, it would
automatically install sendmail and samba, even though I only checked
on the "personal" packages.
Anyone cares to take a crack? I have an identical system at home
which never had any problem.
That's the default behavior of DHCP in Red Hat 8.0. It is probably
best to override that with a set hostname when you use DHCP. However,
I wasn't aware that changing hostnames like that would cause so many
problems for those services. I need to take a closer look at this on
my system.
