SSH Key Permissions

EasyRHCSA Prep10-15 min

The brief

SSH is refusing to use the key in /root/.ssh because the permissions are too open — OpenSSH ignores keys that others can read. Lock down /root/.ssh to 700 and the private key /root/.ssh/id_rsa to 600.

What you'll do

Set /root/.ssh to mode 700 (rwx------)
Set /root/.ssh/id_rsa to mode 600 (rw-------)
