I have 2 servers with which I work: first one is application server and another one is archival server.
I access both of these servers using F-Secure SSH Client using the same user id and public-private key pair for authentication. It means that private key is stored on the Windows machine and public key is stored on both servers.

Now I need to access archival server from application server. To do that I have to do a key exchange first.

What is a standard aproach in this case? Do I just copy my private key from Windows to the application server? Would it compromise security? Or I need to generate a new key pare?

I appretiate your help!

P.S. I am relatively new to Unix administration, so don’t be very hard on me 🙂

    The standard approach is:

    1. Generate on each machine/user a new private/public key pair
    2. Use authorized keys file in .ssh and add every public key
    3. Copy this authorized keys file to every remote host

    Sidenote: The authorized key file as well as the key pairs are user@machine related

    Sidenote2: Usually ppl block root completely from this process. Root should be neither accessible via pw auth nor with key auth.
