OK, I made some progress. When inserting *manually* the private key in the 'manage credentials' page, it works. I tried it before, but I didn't add the prefix and suffix of the key.
What's weird to me, is that I have to manually add the private key. When I'm *selecting* the *'From a file on Jenkins master*' and specify the private key file path (/home/avihay/.ssh/id_rsa) the SSH authentication * fails*, and also when I'm choosing the '*From the Jenkins master ~/.ssh*' Also, the credential in the error message aren't the ones that in the private key file, I don't know from where it fetch it. Now it seems that the Java version in the Slave is not updated, but that's a different problem...
