I get timeout problems when using sendmail, ftp, or rcp. I have no problem sending short messages (about 500 bytes), and I can rlogin with no problem. Faster machines at our site have no problems sending large files (over 10K) to remote nodes so I believe this may be due to the speed of our cpu. I can also use DECnet protocol to get to the remote Ultrix machines and I have no problem sending large files via DECnet mail (mail11) and dcp, so I think this is a TCP problem. Any clues???? -Leo Cazares@ Intel Santa Clara
