: Im sorry - when Ive done FTP that pooped out it was an ethernet

: Flow control is hardware.

: I have one 2.0.5 BSD for other purpose cern httpd use.

What net interface are you using. If the answer is the 3com 3c509/3c579
then there is you're broken frames. The buffers on these cards are too
small for the performance of the network layer. Try a SMC Etherpower and
see if the problem clears up.

I am running FreeBSD over here with the apache server (which is a very
good performer). I serve pages with lots of graphics and don't get any
frame errors. Try www.zeiss.com, my home page isn't that hot.

Cheers,

Ross Walker
