[vox-tech] re: DNS and security

Didn't you already post this on Thursday?

In response, I had already posted on Friday a set of
follow-up questions that I needed answered. Let's

1. DNS. How will editing resolv.conf solve my DNS
issue? My understanding is that that file is the
configuration file for the named daemon. I'm not
running named. Shouldn't need to. A previous install
(Xandros/Debian) ran fine without it. It shouldn't be
required, since my registrar handles incoming DNS, and
outgoing lookups (websurfing) should be handled by my
ISP's nameservers. What I need to know is how to tell
my server where those nameservers are.

2. FTP. Not running an anoymous server. Just need to
upload files for my webpages. Is there a more secure
method I can use (please specify how, don't just say
"yes, there is")?

3. Daemons. Where can I find a comprehensive guide
(including non-free books) to what service does what?
I don't mean a one-line description, I mean someplace
that will really explain it to me in depth. Or, can
someone at least identify the generic ones ESSENTIAL
to my system? Remember, I use ssh to connect and am
running http server. That's all my box does. What
daemons are necessary besides cron, sshd and httpd? 

Thank you in advance.
