[vox-tech] DNS and security

[Cylar Z]

Hey all,

I'm a fairly new Linux admin, running Fedora Core from
Redhat.  Two questions:

1. Outgoing DNS isn't working properly on my server.
The box will respond properly to incoming http
requests (and even allowed me to host 2 virtual
domains, which also respond properly). However, it
does NOT surf the web from the console or ping by
domain name. It WILL ping by IP so I know the issue is
DNS and not my actual connection per se. How do I put
in the DNS info in Fedora Core? I tried logging on as
root, typing "setup" and entering the IP's in the
designated spaces, but no luck. Is there another way?

2. In the interest of system security, I want to run
the absolute minimum number of daemons/services. Which
ones do I really, really need? So far I've established
that I need httpd, sshd, sendmail, xinetd, and
possibly cron. Are there any others that are suggested
that I be running? This server responds to web
requests and lets me SSH in remotely. (I don't use
Telnet.) That's about all it needs to do.
 
Also, is FTP a security risk, or is it safe to leave
this port open?

Thanks, Matt
