SSH Without Passwords
I find it annoying typing my password between machines that I ssh to all of the time. This may be a bit insecure, but it makes my life a lot easier!
- On the source machine:
ssh-keygen -t dsa
Don't enter a passphrase
id_dsa and id_dsa.pub stored in ~/.ssh by default
- Copy id_dsa.pub to the target machine
- On the target machine:
cat id_dsa.pub >> ~/.ssh/authorized_keys
Adds this identity to the authorized_keys
If you have the same home directory on a set of machines, the source and target machines can be the same!
