I haven't had any problems with the Alteon boards. I would suspect the switch. If you want to be sure that the card isn't at fault, get two, put them back to back, and ftp the file from one machine to another. I tried ftping your 'badfile' between two machines with 512K ACEnic boards (connected by fiber, no switch in between) and had no trouble: ftp> bin 200 Type set to I. ftp> get badfile local: badfile remote: badfile 200 PORT command successful. 150 Opening BINARY mode data connection for 'badfile' (12288 bytes). 100% |**************************************************| 12288 00:00 ETA 226 Transfer complete. 12288 bytes received in 0.00 seconds (12.07 MB/s) ftp> I also haven't had any trouble with these boards and an Alteon ACEswitch 180. So I would suspect the switch. Taking it out of the loop, if possible, might confirm whether or not it is the problem.
