Using dce1.nersc.gov with dpss3 and dpss2, this uses the default
route out of dpss{2,3} (ip addrs of
128.3.16.95, 128.3.16.96) to ir30gw (128.3.16.1)
then to irnerscgw (131.243.130.5) and on into
the fddi interface of dce1.

Using dec1.nersc.gov with hpss1 &hpss2 (ip addrs 128.55.128.31 &
128.55.128.32) which are directly
connected to the same network as dec1 (128.55.128.243) I should
get much better performance, but I
don't, I can only assume that there is a problem with the ether interface,
or cable problem...
