Description Jason Keltz 2003-10-03 01:21:02 AEST
A user of mine is connecting via DSL service to our sftp server as part of
OpenSSH 3.7.1p2.  He claims that he used to be able to upload/download files
fine successfully.  Now, he can list files, and download files, but he cannot
upload files.  He says that all uploaded files end up being 0 bytes in size.  I
asked him to upgrade to the latest OpenSSH 3.7.1p2 because he was using an
earlier client.  He did this.  He reports that now, the session goes like this:

[minas@localhost minas]$ sftp cs.yorku.ca
Connecting to cs.yorku.ca...
minas@cs.yorku.ca's password:
sftp> version
SFTP protocol version 3
sftp> put cviureview_online
Uploading cviureview_online to /cs/home/minas/cviureview_online
cviureview_online                               0%    0     0.0KB/s --:-- ETA
> cviureview_online                               0%    0     0.0KB/s --:-- ETA
> cviureview_online                               0%    0     0.0KB/s> --:-- ETA
> cviureview_online                               0%    0     0.0KB/s -> stalled 

... and hangs.

He is running on Linux and the server is running on Solaris, but I have been
able to transfer files locally from the Linux box to the Solaris box.  It seems
like a bug, but I'm not sure what it is or what to recommend to him in order to
assist in solving this problem.

The user can login via ssh without any problems.

Could be an MTU problem.  See:

Problem turned out to be MTU related.
Thanks Darren!
