Well, first dumb question - are the versions of ssh the same?
Is the sshd set up to allow null passwords during login?
Also, I *think* you'll need 'RSAAuthentication yes'.
(I also have PasswordAuthentication yes, PermitEmptyPasswords no
Really dumb question - whats the permisison on authorized_keys?
(Mine is 644)
My authorized_keys file has, at the end, 'rcarruth at msfree', which
is the userid and machine from which I do ssh stuff to the machine
that allows it (with no password, see, it really does work:
rcarruth at msfree> scp rusty at foo:/home/rusty/sap\* /export/home/oodclass.etc

But this is from a Solaris machine (msfree) to a linux machine (foo).
I don't know if that matters, but it might.

maybe, but lets see if you can get away without it first.
First, let me say that I don't know much (anything?) about cygwin. But
I don't think that's the problem anyway, so I'll stick my foot in my mouth
and proceed ;-)

Don't worry about it, an expert is just a drip under pressure anyway ;-)
