Just a thought, do you need to set a proxyserver?
Look into the settings from firefox in the root account and the user account

Kind regards

I typed "route -n"
and it says "command not found"

the only reason I talk about the university is that I tried to describe my internet connection status clearly.

Now I am using the root account, I ping 8.8.8.8 got one line back, and "ping www.yahoo.com" got one line back too.
If I use the FireFox, I can log in the website of yahoo.

Yes, and that could be a clue in solving this one. By the way, repo mentioned proxy settings in Firefox. Had any luck in finding these? Could be a give-away...

Not installed (yet) - I dont know offhand where RHEL gets route. Of course, you did try the command as Root (just checking)...I hope. Otherwise, the command could be "out of reach" indeed...

I checked the "Network Proxy Preferences" . both the root account and the other account is "direct internet connection"

...wait a minute...can you check the firewall on that box? Are users blocked? Are services blocked? The Root is not blocked, it seems.

Um, just a thought, but, you're not trying to hack your way in/out somewhere are ya?

no
there are 3 lines
first two lines:
the destination are different numbers, and the gateway is 0.0.0.0, genmask is 255.255.255.0 or 255.255.0.0; flags are U
the 3rd line:
the destination number is 0.0.0.0; the gateway address is similar with the gateway I pinged. but the 3rd number is different. and the genmask is 0.0.0.0 Flags is UG

The IP address is clearly not there, let's add this now...

route add default gw [that IP address]
...and let's see what happens next

Umm, where does RHEL keep this thing? I'd check System/Settings, it's in a menu there...do that as Root too, of course

...um, of course, you did replace [gateway address] with an IP address...so, this could only mean you're in another netmask. Enter this

ifconfig
...and look for eth0, what's the netmask?
