So, I did a netstat -i on both boxes, and Don't worry about that. Slight differences in the speed of the NICs on the wire (specifically, their ability to send out back-to-back packets) is the main thing that will affect collisions. The collisions are caused by the output packets colliding with the TCP ACKs and is quite normal and expected with half duplex ethernet. -DG David Greenman Co-founder/Principal Architect, The FreeBSD Project To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-hardware" in the body of the message
