Okey dokey!
Download package dhcpd (should also be on your cds, from redhat, I mean)
install the stuff with rpm -ivh dhcpd.blablabla.rpm
Once installed, you got two roads: One is the easy one (but you won't learn that much) = download webmin (webmin.org or something) and that should give you a nice frontend to configure your dhcp server.
Second road is to do a man dhcpd and read the doc on this deamon (server service).
Edit the configuration (in /etc/dhcpd.conf or something) and add some stuff like the network range (I guess that is the bare minimum)

Then do a "service dhcpd start" and you will be in business. If you get problems, you can always go look in /var/log/messages for errors when it starts. You should also be able to see in the log when a clients does look for a dhcp server (dhcp discover) and finds one (dhcp offer from the server)

Yep, I guess that is it. Need more details?
Ask.

Browny_amiga,

There have been a few vulnerabilities discovered in Samba over the last few months. I would hesitate to put it on a machine connected to the internet.

If you do, please monitor samba.org for patches.

As Linux gets more popular, it is facing increased scrutiny.

It is useful to have only one box connected to the internet. This box should have a minimum install and be locked down.

Other boxes can then access the internet via this one.

The security forum has several links to good security resources.

dhcpd HOWTO, its pretty easy to setup:

Well Thank you. That's new to me, I will check this out and fix it immediately.

But a few questions:
1. How come you posted this samba post after the DHCP post? ;-)
2. a system protected by a firewall would not be vunerable to this bug, right? And who (that is not a windows-admin) would be daft enough to let samba be visible to the internet?

Anyway, as I said, thanks for the pointer!
