Change Key Access

1. Change ownership of the key file to the sglbl user:

   sudo chown sglbl:sglbl /data/coolify/ssh/keys/[email protected]
   

2. Set correct permissions:

   sudo chmod 600 /data/coolify/ssh/keys/[email protected]
   

3. Test access as the sglbl user:

   sudo -u sglbl ssh-keygen -l -f /data/coolify/ssh/keys/[email protected]
   

4. Test SSH connection as the sglbl user:

   sudo -u sglbl ssh -i /data/coolify/ssh/keys/[email protected] [email protected] -p 2222
   

Change Port

1. Change the SSH Port in /etc/ssh/sshd_config

• Open the SSH server configuration file:

  sudo nano /etc/ssh/sshd_config
  

• Find the line that says Port 22 and change it to Port 2222 (or any other port you prefer):

  Port 2222
