The above above commands give timeout message doesn’t mean I’m not able to connect to internet. In fact I’m not able to ping/telnet with network outside local university network.

Did I do anything wrong in configuring nntp? Can nntp be used behind proxy connection?
I use Thunderbird to access this (like right now) all of the time;
Thunderbird is configured for a SOCKS proxy, in my case. The account
setting for NNTP still use TCP 119, of course, but the proxy side is using
TCP 5555. Be sure to NOT confuse those two.
Your telnet/netcat test is not valid because you are going through a
proxy; it is, thus, implied that a direct connection (which is what you
are testing) will not work. The same likely applies for any Internet access.
In Thunderbird go to the Edit menu: Preferences: Network…:
click on the Settings button and configure the proxy in there. Also,
under the Edit menu: Account Settings, select your entry for nntp.opensuse.org and be sure 119 is specified as the port. Maybe the
combination has been eluding you. If that does not work, we may need more
information; perhaps Tools: Error Console (clear it out, try things again)
will yield something helpful.

Good luck.

This is using ICMP, not TCP, so it is not really a valid test. If it had
been a valid test (using netcat or something) and if it had come back with
a success, you likely could eliminate the proxy server entirely:

Different protocols are used for these two types of data; did you verify
that your proxy server is willing to do both types of operations?

The last bit there was meant to be steps to get data from the error
console. Besides that, try accessing with Thunderbird from a more-relaxed
network (library, restaurant, etc.) to see if a direct connection works.
If it does, then maybe try finding another proxy server to test to see if
that part of your configuration is good. If so, then your local proxy
server may be blocking NNTP connections.

Exactly; TCP != ICMP so you need the proxy. You need that to work, of
course, but this shows that pinging is not a valid test for, well, almost
anything. It’s nice to know you have end-to-end connectivity, but in
reality it’s a half-test.

Call the administrator of the proxy server.

I don’t think so that they are going to respond. It would be better if I setup may own network without proxy settings.

Oh. I misinterpreted Console as Konsole (Terminal) and thought that some specific commands were needed.

My guess is that you absolutely need them to help. In other words, they
are intentionally blocking nntp access.
The only way for you would be to setup a tunnel to an outside machine,
and use it to connect to nntp servers…

However, only do this with the permission of the network owner. I’ve
done firewall piercing myself, but always with permission - IT sysadmins
tend to get rather cranky when you circumvent their access controls, and
in some instances, depending on any contracts in place, it might be cause
for termination (if employment) or being booted off the network for
violating the TOS.
OK. Now I’ve configured my own network without proxy. And in subscribe options I’m able to see netiq, novell, opensuse, suse and many sub-folders. So, it’s proxy configuration problem. And what should I communicate to my network administrator?
BTW, what newsgroups should I subscribe to? Jim this information is not present on FAQ. Kindly, update that.

Q: “Please give me access to use nntp”.
A: “No way”.
More or less.

The openSUSE forums are prefixed with opensuse.*
That should be pretty clear, I think. The NNTP servers host forums for
Novell, NetIQ, SUSE, and openSUSE, so subscribe to the ones you want, and
ignore the ones you don’t.

To me this seems like something that is intuitively obvious and not in
need of a FAQ entry.
