The box running as my router does report collisions on the card plugged into the hub: 5>xxxxx@router:~$ netstat -in vr0 Name Mtu Network Address Ipkts Ierrs Opkts Oerrs Coll vr0 1500 00:80:c8:d9:ff:0e 353047 0 510083 0 292108 vr0 1500 192.168.128 192.168.128.1 340984 - 499161 - - so it must auto-setup properly. Unfortunately I will have to manually pull the ed card and and put it in a box with a monitor to set it to half-duplex using the DOS program. A while ago there was a long thread on half-duplex / duplex / auto versus manual settings and so forth. I should have read it more carefully. A good book might help too. Can you recommend one? Another question if you don't mind. I set the box up at home on my hub-based network (I took it home over the holidays), but it will be used at work on a switch-based network when I'm done. Will leaving it at half-duplex have any adverse implications on the work network when I bring it in and put it on the switch? I suppose I can set it up as full-duplex again before I come back in, so this question is more academic than practical. > R.

I used to take groups on tours around ESnet so I have probably seen you behind the glass wall or perhaps even met you. My first BSD install was an NFS install off one of the LBL netapps! Anyway, it seems likely this will solve the problem. Thanks for your help and I will report back.
