As written to Corinna, 32-bit i686 openSUSE 11.2 Linux fully patched with
preinstalled openSSH 5.2.

Few MB, or 1.X MB. is behind an ADSL line which is ~12 Mbit/s in the
direction where I'm trying to copy and ~0.6 Mbit/s in the opposite direction.
Note that with 20100328 I sort of "immediately" get the SSH debug trace, whereas
there is no output at all with 20100331. (on Windows 7 Professional 32-bit
German which itself sits on a 100 Mbit/s firehose). 12 hops, 48 ms (the first 10
hops take 7 ms, 11 hops 14 ms, then the typical DSL interleaving on the last hop).

Just tried a slow line as well, multiple times. It still works fine for me with DSL upload speed of 0.6 Mbit/s, remote is which is running some Linux as well. 10 hops.

Are you sure you didn't suffer from some other problem, like multiple
Cygwin versions or something?

I shut down all Cygwin processes (ps -al only listed itself) and replaced cygwin1.dll before doing the trials. What else would I have to do to be sure? Or did I miss replacing other parts of the system for the trial?
