This belongs more in questions... I have a few 2.2.7 boxes with similar network setups and havent seen anything like this. I dont know about the particular board you are using, but I did come across a couple of boards in the past where the order of the placement of the PCI cards made a difference. If you have confirmed that the cable and ports on your switch are OK, try going down to 100 half duplex and even 10 to see if its a switch issue. Some switches (notably my Addtrans) dont do NWAY very well with the Intel NICs. Also, does netstat -ni give any input or output errors ? Another thing you could try is to connect the machine in question to another FreeBSD box via cross over cable and see if you get the same results. ---Mike On Wed, 5 Aug 1998 22:50:11 -0400 (EDT), in sentex.lists.freebsd.misc you wrote: >I've just built a 227R system.
