Tops-20 ftp (usc-eclb.arpa) gives the message "connection rejected for unknown reason" and 4.2bsd ftp (usc-oberon.arpa) gives the message "network unreachable". (This is the second night in a row this week, and I have had similar problems before.) I have also had many mail messages returned with "system unreachable" after three days through both usc-ecl.arpa (milnet) and usc-eclc.arpa. (arpanet) (both Tops-20) Apparently cu20b.columbia.edu (also a tops-20 machine) has no problems sending mail to us, we get the info-kermit digest regularly. Neither the local postmaster or the info-kermit people seem to know a reason for this problem. Where is the proper place to report this type of problem? Are other people experiencing it to? Mail can be gotten through by routing via other systems. (I used to use columbia.arpa, but it no longer understands the % hack and I haven't figured out out to specify an @host1:user@host2 address to tops-20 mm.) For ftp, I just keep trying until it decides to work. Bob Larson -------
