It's typically one, or the other. That being said, I try running both: mii-tool (This will give status of all ethernet devices) ethtool ethX (required to have an eth device specified) Commands to lock at 100FD for both mii-tool and ethtool: #ethtool -s eth0 speed 100 duplex full autoneg off #mii-tool -F 100baseTx-FD eth0 (in case ethtool doesn't work/display) -Put whichever of these these entries into the rc.local file If you have one end of the port set to 100FD for example, and the other end is set to auto-neg, you'll hose your speed. Both need to be set the same for optimal performance. At work, we lock all ports to 100FD. At home, I run everything on auto-neg because my switches and hubs are not managed. -- -Shawn -Nemo me impune lacessit. Ne Obliviscaris..
