How to prevent root SSH login?

[Dipak Bhoi]

Hello Guys,

This post will help you to secure the ssh login. To prevent root SSH login, login to SSH and create an account.

#useradd username

#passwd username

After setting a password for the new account then assign Wheel group to user so only that user can switch to root user account.

#usermod -G wheel username

Then disable root SSH login:

#vim /etc/ssh/sshd_config

Find for the line #PermitRootLogin yes and replace yes with no and remove the hash from line in early.

Then restart the SSH service:

#service sshd restart

Enjoy !!
