I'm experiencing a problem with Yum. When I call 'sudo yum update' it tells me that it can't find any mirrors & after doing a 'sudo yum clean all' it just informs me it can't find any base repo & quits.

This is on a brand new installation of CentOS 6.2 x86_64. I suffered the same problem with Fedora 19 too.

I have several Ubuntu & Mac OS X machines that suffer no network connection problems & I can connect to the InterWeb just fine (via two HP Procurve 2426s).

But can you connect to the 'net via the newly-installed CentOS box?

Yep, no problem at all. Ping & all other network devices are working too.

You have network connectivity but yum does not work. ping works, but yum does http.

Maybe you need to configure a proxy? Have a look at a working Browser's Proxy Configuration.

Another idea: check if you are able to resolve names via DNS.
