We have several dedicated servers.
We need to ensure "root" user can not be accessible through SSH outside of LAN.
I have searched and found the followings #
We need exactly the root user will be unable to access outside of LAN. but other users will be accessible outside of LAN. Because other users can do their work only within their scope.
Our OS details
# cat /proc/version Linux version 2.6.18-308.4.1.el5PAE (email@example.com) (gcc version 4.1.2 20080704 (Red Hat 4.1.2-52)) #1 SMP Tue Apr 17 17:47:38 EDT 2012
Please help me to resolve the issue?
