yes i can ignore them, it was only a query.

one machine is P2-450 and the other is AMD K6-2-350 both with D-link DFE500TX
nics and on the same switch witch is a D-link 10/100 autonegotiating switch.
The switch reports full-duplex always, even if the tulip-diag prog say
half-duplex.

we transferred a 40MB file using scp. which seems to transfer at about 1MB
sec.  Shouldn't this be around 12MB sec, at 100Mbits.

We also have another switch different model and same result.
