What's odd to me is that I get just fine throughput from/to hosts in our DMZ. The gateway is on the 10/100 segment. Things only get crappy when I try to talk to boxes (linux and windows) on the 10/100 segment. The gigabit box is on a DLink 8 port switch, which connects to a 24 port Trendnet box. Everything was ok 'til I went to fc2 from RH8. Under RH8 I was using an older version of e1000 driver. I'll try switching off autonegotiation. But I'm still stumpied. Here's my output from mii-tool. # /sbin/mii-tool -v eth0: negotiated 100baseTx-FD flow-control, link ok product info: vendor 00:50:43, model 2 rev 3 basic mode: autonegotiation enabled basic status: autonegotiation complete, link ok capabilities: 100baseTx-FD 100baseTx-HD 10baseT-FD 10baseT-HD advertising: 100baseTx-FD 100baseTx-HD 10baseT-FD 10baseT-HD flow-control link partner: 100baseTx-FD 100baseTx-HD 10baseT-FD 10baseT-HD flow-control thx s On Thu, Aug 19, 2004 at 01:23:09PM -0500, Clay Fandre wrote: > Is the duplexing set correctly?
