RH will not "ping" - Why?

["V. Leveque" <vleveque earthlink net>]

To the list,

I've tried some suggestions re: why my Redhat 5.2 system will not respond to
a ping, not get a respoonse from the rest of my network.  Nothing works yet.
I have both Win NT and NetBSD systems -- same result with both (no ping
response in either direction).  All systems are in the 192.168.1.x private
address space, and all have a subnet mask of 255.255.255.0

I've tried swapping cables and even the NIC with a system which works.  Same
result - so it isn't a bad cable or NIC.
 
The Linux machine boots fine.  ifconfig -a indicates the proper address and
mask, and shows a MAC address.  I have noted that after executing ping from
the RH system, I get a lot of transmitted packets, but none received (ZERO).
Hmm...

Again, if I set the Linux machine's IP address to be the same as my NT
machine, the NT machine complains there is another system with the same IP
address.  IN the event log, it gives the correct MAC address for the Linux
machine (indicating the frame came from it).  

The Linux system is sending something on the network, but not receiving
anything.  Why?

I'm still baffled.
