Who is system administrator?

5.Who is System administrator?
Ans.
1. Linux system administrator is the person who has “root” access, which is to say the one who is the system’s ‘superuser’ (or root user).

2. A standard Linux user is limited to whatever he/she can do with underlying engine of the system.

3. But root user has unuttered access to everything that includes user accounts their home directories and the files inside those directories, all system configuration and all the files on the system.

4. A certain body of thought says no one should ever log in as “root” because System administrator tasks can be performed more easily and safely with others.

5. Because system administrator has full privileges his first duty is to know what he is doing.

6. The word duty implies a degree of task or work which is hard to perform.

7. Clearly it’s a tremendous flexibility of system measured against the responsibility to run a tight organisation.

8. These duties do not so much constrain you, the system administrator, as free you to match the job task.

With root squashing clients root account can’t even access or change files that only server’s root account can change or access. Client security considerations: 1. Disable SUID (set UID) programs on NFS mounts using nosuid option. 2. Prevents server’s root account from creating an SUID root program on an exported FS, logging in to the clients as a normal user, and then using the UID root program to become root on the client.
