What version of ssh-keygen and/or the SSH packages do you have?

I'm using Debian's ssh, which is really OpenSSH v2.

Read your local ssh-keygen manpage and check to see what if any options
it requires to specify keytype.  Usual keytypes are 'dsa' or 'rsa' for
version 2, or 'rsa1' for SSH version 1.

Should be "ssh-agent", not "ssh_agent", my typo.

That would be the problem of the above.  Once sorted, should work.


Peace.
