That does not make sense. Are you implying that you cannot ping the box, yet 
if you run something on the machine's terminal, you can browse the web, 
etc?

I've never seen this before. My semi-educated guess would be that you're 
hitting some bizarre kernel bug. That would be the only thing that could 
cause something like this to happen.

I presume, of course, that you're not running something like portsentry, 
which can trip up and firewall an individual IP address, if it sneezes the 
wrong way. That would be one explanation for not being pingable from some 
another IP address, yet the machine being usable otherwise.

Something like this could also indicate a corrupted install or a 
configuration file.

Why does it take a "serious 15 minutes:?

Other things to check is your hardware components. Run memtest, to check for 
faulty RAM. Configure and install lm_sensors, and see if any motherboard 
sensors are reporting faults. Reseat all PCI cards on the motherboard. Check 
that all cables are properly seated. Run smartctl, and see if your hard 
drives are healthy. Check all the cables. Look for worn out IDE/SATA cables, 
replace as needed. Check wired ethernet cabling. Make sure that it's rated 
for your actual ethernet speed.
