Setting up password-less ssh
- Generate ssh key-pair for local workstation:
ssh-keygen -t rsa
; accept default options and hit return when prompted for passphrase. - Copy public key (
~/.ssh/id_rsa.pub
) to remote system:scp ~/.ssh/id_rsa.pub remotesys:~/
If this is the first connection to the remote system, typeyes
to accept the remote system key. - Login to remote system, configure remote system to trust public key:
ssh remotesys
- create ~/.ssh if it doesn't exist:
mkdir ~/.ssh
cat ~/id_rsa.pub >> ~/.ssh/authorized_keys
chmod 700 ~/.ssh
-
chmod 640 ~/.ssh/authorized_keys
- Logout of remote system, and repeat login to check that everything works correctly. If so,
~/id_rsa.pub
can be removed from the remote system.
