Disable root login to SSH

Ástþór IPÁstþór IP

Allowing root logins to your SSH damon is a big security threat. If the SSH port is open, hackers will probably at some time attempt to brute force your root password. It’s a good idea to disable root logins to SSH and instead use a normal user to login and type “su -” to enter the super user shell or sudo to perform tasks that require root privileges.

1. Open the SSH daemon config file and change this line: (pico /etc/ssh/sshd_config)

PermitRootLogin no

2. Restart the SSH daemon

/etc/init.d/ssh restart

    I prefer to permit only key authentication for root login:
    PermitRootLogin without-password
