How to auto login a .ssh server from a .ssh2 server?

Question

I have a server A which ssh-keygen produce a .ssh2 direcotry and id_dsa_2048_a* files and a server B which ssh-keygen produce a .ssh directory and id_rsa* files and a server C like B

How can auto login into B from A, or login into A from B (ssh without password)?

I can setup auto login from B to C.

I've never dealt with trying to make ssh and ssh2 talk to each other myself but [I found this which may be helpful](http://burnz.wordpress.com/2007/10/17/how-to-make-ssh2-work-with-openssh/). — Ladadadada, Oct 16 '14 at 16:08

Yeah, just define the hosts in your ~.ssh/config file:

Host hostB
    ProxyCommand ssh -q -W %h:%p hostA

There is no `.ssh` in hostA, so I assume I should do it in hostB? – Sato Oct 16 '14 at 08:38
As far as I understand you want to login from your workstation to serverB using serverA as a hop-station. If so, you need to modify the `.ssh/config` on your workstation. – neutrinus Oct 16 '14 at 08:48
Sorry, I mean directly.. – Sato Oct 16 '14 at 09:07
So use `ssh-copy-id` – neutrinus Oct 16 '14 at 12:08
