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.

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?

  • 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.
