I have generated pair of both public and private key for one remote host. Now I want to add another private key in open format to connect via ssh to second remote host, but ssh denies connection with "Bad passphrase" when I want to add key with ssh-add "key_name". I only have private key, which in Putty on Windows machine works fine. I only have two files in my /home/user/.ssh directory:

id_dsa
known_hosts

    You don't need to add a new private key. You need one private key (that you have already generated). The public key (of that private-public pair) can be sent to as many remote hosts as you want. That's why it is "public". See this answer

  • On my virtual machine key is working, on my host keeps hitting me with bad passphrase.

Easy as pie.

Simply go to the .ssh folder in your home and add the file config

nano /home/${USER}/.ssh/config

and add the following lines e.g.

Host duck-a-rub
HostName mail.man.com OR <IP-Address>
User rubberduck
Port 223
IdentityFile /full/path/to/keys/rubberduck_id_dsa

save the file and give it a try.

ssh duck-a-rub
