Answer 1

This looks the same as the problem in this post. It was patched in version 3.1.1, so if you download the latest version (3.1.2) the problem should go away.

Ouch, sorry. I should have used the search engine before posting a problem.

Answer 3

I updated to the 3.1.2 version. The problem with "SHA-1/RSA/PKCS#1: not initialized" is gone. However there comes another exception:

com.enterprisedt.net.j2ssh.transport.TransportProtocolException: The connection did not complete
at com.enterprisedt.net.j2ssh.transport.TransportProtocolClient.onStartTransportProtocol(Unknown Source)

I will try to get the debug informations and post here as soon as I get some. Meanwhile if you have any idea, what could be, dont hesitate to tell me.
