Greetings, I have been trying to fix a "problem" which seems to be out of my league as to the cure. It deals with transfer rates during an FTP, UUCP or other type of transfer between a DOS-based machine and a FreeBSD 2.1-based machine. Under windows, I can do a FTP transfer to the BSD box using a generic FTP application running with Winsock 2.1f the transfer speed to/from the bsd machine is around 280kbps which is fine for what I need. There is no problem here. However, using the exact same machine but under dos using a standard packet driver and a FTP app for DOS I get a transfer rate of 331kbps going from the BSD box to the DOS box but only a 6.5kbps rate going from the DOS box to the BSD box. 6.5kbps is just too slow to transfer a large file to the BSD box. The strangest thing about all of this is this was working fine (350kbps under dos both ways) under BSD 1.1.5.1 and the exact same DOS machine setup. I am getting similar poor performance when doing a UUCP transfer in either direction when using BSD 2.1. I get about 5kbps to or from the BSD box yet under 1.1.5.1 it was around 250kbps when running a UUCP session. Any ideas what could be causing this? I have not changed the DOS machines in years so I don't think it was a re-configuration problem there. The only item that was changed was going from BSD 1.1.5.1 to 2.1.0. I have tried changing the TCP extensions and that had no effect. Thanks in advance for any ideas you have. I'm sure this is something simple but I have tried everything to figure it out but with no success. I'll gladly capture a tcpdump of the PUT session that is getting such slow rates and send it to whoever. Thanks, John Brogan ReplyNet
