Hello,

I know, problems have been reported concerning the use of ssh on windows
xp ("ssh hangs"). I would just like to confirm, if this is, what I'm
dealing with. And perhaps somebody knows some workaround until there is
a fix.

I have a cygwin installation on XP at my customers and on W2K at home.
My aim was to make some shellscripts I wrote available to some of the
windows users via a php-interface for administrative tasks on their
linux internet servers. 

I am using ssh with public keys to connect to the linux-servers.
What works:
I can ssh from my linux box to the linux servers.
I can call "system(ssh remote-user AT remote-server command)" from php on
linux.
I can do all this on my W2K box (Vmware), when I start the apache
service as the same user, that has the public key.
However on the XP computers, I can only use ssh from the command line,
calling some script containing ssh via PHP hangs.

This is the client's errorlog (-vvv):
