(/etc/rc.d/init.d/network stop. on redhat 5.x machines), then "rmmod tulip", wait about 10 seconds, and then "/etc/rc.d/init.d/network start", check to see if you can ping out. ( wait about 30 seconds (the driver will switch from 10Mb to 100Mb to try and find an active port, and takes a little time..) I have a pair of DE500's that require this probe, rmmod and re-probe sequence to behave properly. Dave J. Andruczyk Linux Systems Admin Buffalo State College
