I'm ssh-ing between two machines and entering the passphrase key every time I need to connect to the other machine's ssh server. I added my key to the ssh-agent daemon using the below commands, which allowed me to use ssh one time without using the password, but when I returned back to the machine I originally ssh-ed from it prompted me for my passphrase key again when trying to ssh to the same machine, which totally defeats the point. How can I get the passphrase to hold permanently so I won't have these issues.
exec ssh-agent /bin/bash
Enter passphrase for /home/user/.ssh/id_dsa:
