Summary: scp transfers from remote cygwin machine fail with ssh
versions >= 4.6
Product: Portable OpenSSH
Version: 4.6p1
Platform: ix86
OS/Version: Linux
Status: NEW
Severity: major
Priority: P2
Component: scp
AssignedTo: [email protected]
ReportedBy: [email protected]
I am in France and try to load a 20 MB file from a server in
California. Thus from California to France. In California, the server
is a Dell 2650, running WIndows 2000 with cygwin installed. The ssh
version on that machine is 4.7. The server sits on a DSL line with a
maximum up speed of 250 kbits/s. Down is 1.5 mbit.
In France, I run various versions of Ububtu and Redhat, or windows XP
sp3. In france I am also on a DSL line that is about 4 times faster
than the California one.
For several scenarios, the file transfer stalls transferring a large
file. It stalls after around 50 kBytes. For some other scenarios, the
file transfer succeeds.
the specific command used is this: scp
[email protected]:/cygdrive/m/mm/mmdev/* ./
For these setups in France, the transfer fails:
Centos 5.4 ssh version not known.
Ubuntu 9.10 ssh version 5.1
Ubuntu 7.10 ssh version 4.6
In these setups, the transfer succeeds:
Ubuntu 6.10 ssh version 4.3
Windows cygwin ssh version 4.7
I have tried this several times with several i86 computers in France
and three total WIn2k server computers in California and the problem is
100% reproducible.
Here may be a valuable clue: I did the same experiment, but instead of
loading a big file from my server in California that sits on a DSL
line, I tried to download a big file from one of my nearly identical
servers at a data center in Chicago, again toward France. In this
scenario, the transfer never fails. All setups work.
