network problems after RH 7.2 --> 9.0 upgrade

[Thomas Walter <tbw geo hunter cuny edu>]

Hi Gurus,

I upgraded a Dell machine from RH7.2 --> 9.0. It seemed to go flawlessly
but not I can't SSH into the machine, I get a "host unreachable" message.

If I ping the machine I get the following response:

ping -s graupel

Any ideas what the problem might be?
