Hi folks, after upgrading to latest cygwin1.dll and openssh I have massive problems with ssh/scp. Using e.g. the same scp command it fails from time to time called from the command line. Unfortunately it fails more often when called from a shell script and quite every time when this shell script is called from a DOS batch called by a Java app.
See the output of scp -v -v in the good version:

The singel difference is, that in the successful case the client sends an
exit-state, that is not received in the unseccussful version. The problem
manifests more often with using a shell script and a DOS batch:
========= scpwin ========
#!/bin/sh
for a in "$@";
do
case $a in
-*) ARGS="$ARGS $a";;
*) if test -n "$a"; then ARGS="$ARGS \"`cygpath -u \"$a\"`\""; fi;;
esac
done
#echo $ARGS | xargs echo
echo $ARGS | xargs scp
========= scpwin ========
and
========= scpwin.bat ========
@sh -c "scpwin '%1' '%2' '%3' '%4' '%5' '%6' '%7' '%8'"
========= scpwin.bat ========
Called from a bash shell (repeast fast 4 or 5 times):
cmd /c "scpwin.bat -v -v project.xml [EMAIL
PROTECTED]:/devel/maven/home/public_html/repo/essencio-perActa/poms/idxmgr-1.0.4-SNAPSHOT.pom"
Worst case is calling the scpwin.bat from within Java (app also started from
the bash shell) using Runtime.exec(Object[]). Then it fails nearly every time.
Any other information I can provide ?
