           Summary: sftp working for list files, and download, but not for
                    uploading
           Product: Portable OpenSSH
           Version: -current
          Platform: UltraSparc
        OS/Version: Solaris
            Status: NEW
          Severity: normal
          Priority: P2
         Component: sftp
        AssignedTo: openssh-bugs at mindrot.org
        ReportedBy: jas at cs.yorku.ca


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 at localhost minas]$ sftp cs.yorku.ca
Connecting to cs.yorku.ca...
minas at 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.
