Generated keys, added to my account, ssh not working (Permission denied)


I am on Mac os 10.9. I generated my ssh key with ssh-keygen. I pasted the pub key as a new security key in my account. I restarted my computer. Then $ ssh [email protected] echo Permission denied (publickey).

I tried several times with no progress. I browsed for ideas but found nothing of help.

Here is a trace of verification against the server:

Thanks for your help!


Solution

  • Based on your logs, it really looks like the wrong ssh key is being used.

    I created an account, added an new ssh key I generated with ssh-keygen (no parameters)

    Debug snippet shows the following;

    debug1: Offering RSA public key: /root/.ssh/id_rsa
    debug1: Server accepts key: pkalg ssh-rsa blen 279
    debug1: read PEM private key done: type RSA
    debug1: Authentication succeeded (publickey).
    

    ssh-keygen -l showed a fingerprint which matched the fingerprint displayed in the cloudbees portal.

    Its a bit of a stretch but... can you tell me what parameters you added to 'ssh-keygen' when generating the key? You may have stumbled on an unsupported key format..

    Otherwise, start again with a new key..
