Welcome to the club (Knowing very little).
I'm not sure whether it is DNS or loopback networking that might be set
up wrong. Try
ping -c1 127.0.0.1 and you should get a success.
DNS for Dummies
/etc/hosts: Holds hostnames & IPs you know. Used to be the Internet!
The first line should be
127.0.0.1 localhost.localdomain localhost
/etc/host.conf: Holds the search order. These 2 lines
order hosts, bind
/etc/resolv.conf: Holds places to search, with lines like
search domain1, domain2, etc.
nameserver 127.0.0.1 # only if you have your own dns programme
and any other servers get a line. If you want your own dns server, look
at djbdns (I know, but it works well and is compact)
