It appears you are saying that your "server" machine has trouble receiving (no matter if it is acting as a server or a client), if I understand your statement of the problem. At this point, I would suspect hardware. Some things to try... 1) have you tried a different _client_ machine to send to the server? Are the results the same? If not, problem is on "server" machine's RCV port. 2) try switching the cable around (plug the ends of the cables into the opposite machine). This could point to the cable if your "server" machine suddenly starts RCV'ing ok, but the client now gets RCV errors. -or- (better) 3) Try a different "known good cable". 4) Do you have any alternate ethernet cards you can try? -- Perhaps in the "Server" machine you have 2 network cards? Can you temporarily reconfiguring to do the tests with the other network card, or do you have a spare around to try to substitute in? 5) If both machines are linux, you can rule out file-system interactions by using the "nttcp" package. Run on 1 machine (artibrary client) with "nttcp -i" and then on other machine -- output looks roughly like: machine1:/> nttcp -T machine2 Bytes Real s CPU s Real-MBit/s CPU-MBit/s Calls Real-C/s CPU-C/s l 8388608 0.71 0.04 94.7974 1560.9254 2048 2892.99 47635.7 1 8388608 0.71 0.12 94.0853 568.8060 5809 8144.10 49236.3 6) if one is a windows machine, you might use the "cygwin" package to load "rsh" or "ssh". You could xfer files with rsync (which can tell you speed), or use "dd" into a pipe. Be aware that rsh is insecure and should be made visible to "the outside world", and 2) ssh has performance overhead due to it's encryption. 7) Make sure network card in suspect machine is "reseated" -- possibly even try a different slot -- not likely to change things, but I've seen it happen. Good luck... Linda Walsh Frits Spieker wrote:

I have tried everything that google can throw at me, but no results.
Any idea what might be the problem here?
If I convert one of the other PC's into a server and the "server" into a client, same result: from the temporary server to the temporary client (the real server): dead slow.
