I am trying to ssh two machines and I would prefer to use keys generated for authentication rather than password. This will enable me to automate port-forwarding and many other things.
Note: My server is debian.
Below is what I did.
I generated the key:
ssh-keygen -t dsa
Copied the id_dsa.pub to the remote server's ~/.ssh
- ssh-add -D to delete old keys. Gues I didn't need them
ssh-add ~/.ssh/id_dsa to add the private id 5.tried to connect to the external server as
ssh root@remote-ip
- Still settled for password even after my acceptance to be added on known-hosts.
- Tried ssh -vvv root@remote-ip and log obtain is posted below.
