I'm hoping that this forum can lend a hand to my lack of skills in networking.
My diagnosis so far is that "ping" works for external sites like google.com but when I open up a browser, and I've tried several, no internet sites can be reached.
Up until now all network issues I've resolved were completely fixed once "ping external_site" was working but its not the case this time. So I'm puzzled.
I found a thread from a month ago with a very similar problem but it doesn't seem to have the same solution:
The machine is
Red Hat Enterprise Linux AS release 3 (Taroon Update 1)
It is one of serveral almost identical machines that are working, so I think the network settings (resolve.conf) are configured correctly.
Any help would be a lifesaver. How can ping work but browser http not work???
