I suspect there's something wrong with your private key, probably the first line. Don't paste it into the question. How did you generate the private key? Can you try creating a new one? (Remember that they come in pairs so only do this if you can change the public key at the other end too.) |

The key is most likely either SSL or in PuTTY format. It's not compatible with Linux ssh client/server. |

Right it is the format - looks like a Putty generated key. To properly cut/paste a puttygen key see here: http://www.howtoforge.com/how-to-configure-ssh-keys-authentication-with-putty-and-linux-server-in-5-quick-steps However - you are not sshing from a Windows computer, are you? Looks like you are sshing from a Debian-based server to a private IP. Are you trying to use the puttygen keys on another host? Why do that instead of 'ssh-keygen'? I am curious what you are trying to do here. Can you give more detail? |
