Transfers interrupted when uploading
Dear all,
I have a very nasty problem: I can't upload files from my machine.
I'm connected to the Internet via an ordinary dialup (ppp). All goes
smooth, I can navigate and work remotely via telnet or ssh.
I'm running a potato 2.2r0 on a laptop.
Problems arise when I try to serve files by either uploading them directly
via ssh or ftp towards some remote, or by connecting to a remote and try
to
retrieve files from my machine.
What happens is that after the first few Kb's, the transfer hangs and I
can
only disconnect by hanging up. Note that SMALL, ascii tranfers end
succesfully.
This is an example of what /var/log/messages tells me in one case where
I was trying from a
remote to log into my machine and get files via ftp:
--------------------------------------

Jun 24 19:29:36 paperoga pppd[254]: Exit.
--------------------------------------
an example of the progress of an ftp session is:
150 Opening BINARY mode data connection for celle.tar.gz
(xxx.yyy.zzz.kkk,1100).
################################################################
(64x1024 and then serial line hangs)
Analogously an ssh session hangs after:
celle.tar.gz 100% |*****************************| 155 KB
00:00
Does anybody have any clue of what is happening to my transfers?
(are there other logs which may tell me more?)
Do I have to give away my monster-laptop to my newborn to amuse
himself?....
Thanks very much.
