Disable Your SSH access accidentally with scp

4 days ago

SSH access was disabled after an SCP file transfer due to changed home directory permissions.
The home directory permissions were inadvertently set to 777 (rwxrwxrwx) by SCP, matching the source directory's permissions.
OpenSSH's security checks rejected SSH key authentication due to the overly permissive home directory.
The issue was resolved by reverting the home directory permissions back to 700 (rwx------).
A bug report was submitted to OpenSSH, leading to a quick fix slated for the next release (10.3).
