PermitRootLogin

I'm confused about PermitRootLogin settings. It seems I need to set it off because of security reasons. But how can I reach my server with root-like permissions. I dont know how can I give root permissions to user?  I heard about "sudo" but I dont have any idea about that too.

Ok
its always good to use PerminRootLogin  = No
so hacker woudl not be able to login as root, incase your password is compromised

how ever, work way round is

sudo or su -

if you have sudo installed in your centos

then type

visudo

you will see a line call

## Allow root to run any commands anywhere
root    ALL=(ALL)       ALL     ------------------------------------------------------->
username  ALL=(ALL)       ALL

you just need to add username with ALL=(ALL) ALL  ( as written above)


now login to the server with username

now if you want to do any administrative task

type

sudo
it will ask for pasword, give it the password

now you will become root user


or after login to server as normal user type su -
it will ask for root password, after giving it,you will change to root user

i will sent you some other article aswell
