[comp.protocols.appletalk] NCSA Telnet ftp grief

wilson@csli.STANFORD.EDU (Nathan Wilson) (12/22/88)

Several people at my site are having intermittent problems getting
ftp to work using NSCA Telnet.  The site consists of the following
machines:

LocalTalk Network:
	1 Kinetics FastPath
	4 Mac II's (System 6.0.2 Finder 6.1 w/Multifinder 6.0.1)
	1 LaserWriter NTX II

Ethernet Network:
	1 Kinetics FastPath
	2 Sun 2/50's
	1 Diskless Sun 2/120
	1 Sun 2/120 Fileserver
	1 Kinetics FastPath

The Macs all use NCSA Telnet regularly and the fileserver is
running CAP.  The problem is that periodically giving the ftp
command (as per Send FTP Command in the Network menu) just causes
the command to be printed and process to start, but nothing gets
printed out.  Once this occurs no one can startup an ftp session
until some unknown event occurs at which point things start working
again.  I have attempted to localize the problem with minimal
success.  Sometimes just power cycling the kinetics box is
sufficient, other times shutting down all the macs, halting the
fileserver, power cycling the kinetics box, rebooting the fileserver,
and rebooting the macs is insufficient!  Throughout all of this
both existing and new telnet connections work just fine.  If anyone
has any idea what the problem might be please send me a note.

PS Now that was weird.  Prior to writing this note I tried
starting up ftp and left it running to see what would happen.
After a long while (~5 mins) I saw something print out in the
telnet window.  I assumed it was the sun timing out so I
immediately quit.  I then noticed that it had actually connected!
I immediately tried to restart the connection with no success
so far (it has now been >10mins).  Oh well.
