I have access to a CentOS server with a user that its not root but belongs to the sudoers list. I do not have the password of root, nor I can't find out what it is (policies of the people who gave me access to the server).
I want to enable SSH login with root, meaning I don't want to keep logging in to the server with some user, and always do sudo su - in order to do about anything. So far I was able to enable SSH login with my user and a passphrase, which is nice, but I would like to be able to login directly in the root user.
Can I do this without the password of root? How? Any links/books or information would be appreciated.
I don't know if the reason why I need this is relevant to the question, but is this:
I have 64 machines just like this server, and I have to install in each of them some software. In order to do this, I set up a passwordless SSH and a bash script that installs the software in each machine. The thing is, the software I need to install requires root permissions and if I include in the bash command sudo su I have to write 64 times the same password each time that command appears in the script. That's why I need to enable ssh login with root somehow.
