Here's the short version.  I played with the netmasks trying to get the
thing working.  Both netmasks are now 255.255.255.0, and it still
doesn't work.

Since my last post, I swapped the configs in
/etc/sysconfig/network-scripts.  Now the 172 address is using eth0 and
the 66 address is using eth1.  Even with the hardware swappind addresses
it is still the 172 link that is dead.  This takes all hardware issues
out of the loop, right?  It has to be something in the 172 routing that
is munged.

I still have all firewalling turned off, routes look fine, but no
pingy-pingy.  Or arpy-arpy for that matter.  The card never responds
with an arp-reply which is why the traceroutes get !H's.

Help!
