What happens if you do `ssh cyg...@cygwin.com`? That'll normally point out what the error is. I expect either (a) you've managed to not copy over your `.ssh/known_hosts` file somehow, or (b) some of the files you've copied over have the wrong permissions; my money's on the latter. If so, `chmod 600 ~/.ssh/*; chmod 700 ~/.ssh` will normally get things going again. Adam
