SSH Login without password
Follow the following steps in order to login between the Debian machines without giving the password each time:
- login to a Linux machine
ssh-keygen -t rsa
and press Enter until you return to the prompt.
cp ~/.ssh/id_rsa.pub ~/.ssh/authorized_keys
After this, you will login with ssh without password. First time you login to a host, you will be asked to answer "yes" to connect.
