ok . you are not reaching the servers at all
Is there a firewall between you and the servers?
try ntpq -p ns1.usg.edu
here is what I got on a machine with direct access to the net. I am
going to preformat the output
[EMAIL PROTECTED] bhughes]$ ntpq -p ns1.usg.edu

this tells us that ns1.usg.edu is currently synced to navobs1.gatech.[edu?]
hmm lets see the ips

yup that was a good guess. Anyway the ntpq documentation page explains
all this better than I can but suffice it to say that this machine is
pretty damn close to the top of the food chain.
Trouble is you can't talk to it. find out why, Usually firewall issues
port 123 udp and tcp is what I usually open up. I don'tremember if it
uses both or not but lets get it working before we get to semantics.
there is also a debugging techniques page on my 7.3 machine in
/usr/share/doc/ntp-4.1.1/
