           Summary: cygwin rsync hangs when initiated remotely after
                    transfering some files
           Product: rsync
           Version: 2.6.3
          Platform: x86
        OS/Version: Linux
            Status: NEW
          Severity: normal
          Priority: P3
         Component: core
        AssignedTo: wayned at samba.org
        ReportedBy: cfinley at u.washington.edu

I am trying to backup a Windows XP SP2 workstation to a Debian GNU/Linux server
using ssh, cygwin and rsync.

It appears the XP rsync locks up after transferring some files (it transfers a
few more files each time it is attempted) but hangs every time. The XP rsync
process must be killed manually, even if I cancel the rsync on the Linux side.

The Linux account can ssh into XP using client keys.
I can scp the entire source data without any trouble.
No XP event log entries (except key authentication & service start-up).

The Linux initiated rsync command:
rsync -vrte ssh --stats --progress xpuser at xpsource:/cygdrive/c/Data/

I can initiate the rsync from the XP machine and it runs smoothly:
rsync -vrte ssh --stats --progress /cygdrive/c/Data/
debuser at destin:/home/usershare/xpuser/

Debian Sarge Destination:
Linux 2.4.26-1-686 
rsync  version 2.6.3  protocol version 28
OpenSSH_3.8.1p1 Debian-8.sarge.4, OpenSSL 0.9.7e 25 Oct 2004

Windows XP Pro SP2 Source:
Athlon 64 3200+
cygwin 1.5.12-1
cygrunsrv 1.0-1
rsync 2.6.3-1
openssh 3.9p1-2

The rsync-debug script dies immediately without transferring any files:
protocol version mismatch - is your shell clean?
(see the rsync man page for an explanation)
rsync error: protocol incompatibility (code 2) at compat.c(60)

The log file on XP contains:
rsync: writefd_unbuffered failed to write 4 bytes: phase "unknown" [sender]:
Broken pipe (32)
rsync error: error in rsync protocol data stream (code 12) at

This created a zero length out.dat file:
ssh xpuser at xpsource /bin/true > out.dat

Searching Google, this seemed to be the closest match:

any help?

Your time and expertise are greatly appreciated. Please forgive my newb-ness.
Let me know if I should try anything else.
