The short answer is YES. As Chris pointed out, your FQD needs
to be in the /etc/hosts file.
BTW, and FQD is a fully qualified domain name, ie: you.your.domain

Subject: Caching DNS and /etc/hosts entries?
hi all. i have a linux box as a firewall to my network. i'm running a
caching-only dns server on the linux box. i'd like the dns server to
resolve the aliases in my /etc/hosts. it seems to already do this for
one of the entries, but not the others. from the perspective of a client
on my internal network, the dns server resolves www as
www.ourdomain.com, as it is in /etc/hosts. anyone know how to get the
dns server to use the rest of /etc/hosts?
cheers,
ben

You don't. But you will still need to set the the /etc/host.conf
file to tell networking to look at the /etc/hosts file.
Check the man page.

Subject: Various Questions About Hostname, DHCP, Gateway
Date: 7 Apr 1999 19:43:51 GMT
Hi!
I'm talking about us cablemodem users who are given dynamic IP addresses
having to use DHCPcd. We are given no hostnames at all from our ISP, but
my buddy just across town who have cablemodem with another ISP, which give
out static IP, they get to have a hostname such as 'maze.powersurfr.com'
when his IP address is 24.102.74.**. When doing an nslookup using his IP
address, I actually get 'maze.powersurfr.com' whereas when I do an
nslookup on myself with my IP, I only get '24.64.14.87.ab.wave.home.com'.
The reason I ask is because I'd like to setup a small network at home
where I'd have a Gateway setup using DHCPcd to obtain an ip from my ISP's
DHCP server and in turn use IP-MASQ to assign IPs for the computers I'll
have at home, behind the Gateway.
And I'm wondering if it's possible at all to be able to setup a hostname
on either the Gateway itself or any of the computers behind it? As well,
Can that Gateway double to act as a Firewall as well (I plan to use
ip-chains)?
Thank you very much in advance.
Steve

Ignore this bullshit. They try to redirect you to some site, probably
a porn site, and the redirector closed the account down.

We are moving from Netware to Linux as our main file server. One of the
features we like about Netware is the "salvage" feature in which we can
resurrect the most recent version of files which the user has mistakenly
deleted. Is there a similar feature or add-on package for Linux which would
enable us to provide a similar service?

A better solution would be to create a simple shell script like the one
below (that I use) that allows users to telnet in to change their
passwords, and that's all. Sure saves the headache of changing
passwords for the users.
Remember to add /usr/local/bin/pwchange to /etc/shells of course.

I just purchased a 3Com Megahertz 3c574B 10/100 card.
I got it working, but upon reboot it started giving me problems.
If you get any information about this card, please pass it along to me.

Okay, then we need to fall back and figure out why. :-) The routing looks
correct. If you can ping yourself but nobody else, it sounds like either a
bad configuration of the network card (I/O port or IRQ conflicts) or a wiring
problem.
If this is a dual-boot box, have you tested the network in Windows? If it
works there, that will eliminate wiring as a potential issue. What kind of
network card do you have, and what IO and IRQ do you expect it to be on? How
is your network wired? If it's with coax, do you have terminating resistors
on both ends? If it's with RJ-45 connectors (twisted pair wire with big
phone jacks), are you getting a green link light on both ends?
What I'm seeing in your ifconfig is IRQ 10, port b000. That sounds like a PCI
card. What other cards do you have in the system? Do you have a
Soundblaster? They often have an IDE port that defaults to IRQ 10 and could
potentially be interfering. Even if it works in Windows, you may still have a
conflict in Linux; Windows is much smarter about changing card resources
around to avoid problems when it can.
Another thing to try if you're impatient waiting for me to get back to you is
to simplify the system as much as you can; pull all the cards you can while
still having a functioning machine. Basically, bring it up with a video card,
a network card, and a hard drive. That will help eliminate hardware conflicts
as a potential cause.

A lot of ISPs I've looked at recently seem to use the server assigned
DNS 'feature' of DUN under windows. I've yet to find a reference to a
way of duplicating this functionality under Linux. Am I just looking in
the wrong places or is this not possible under Linux? Any ideas?

Usually the answer to cross-subnet browsing is WINS. DNS name services aren't
related to browse services at all. If you run a WINS server and get every
machine in the network pointed at it, your browse services will (normally)
magically start working.
