Try one or more of the following things:
- Use puttygen to import your private key, and then export as .ppk
- Load your key.ppk into pageant, and let it manage your private key(s)
- Log in using your private key from the server (ie. login to the
server with your password, and then from the shell ssh
username at localhost).
Please inform me of your results.
