Thread: superuser account list

  1. #1

    Default superuser account list

    Yast->Users and Group Administration->set filter: system users

    I get a very long list, including an account called "nobody". Can someone explain this in detail? Thanks.

    Just to clarify something, your subject mentions 'superuser' while you
    later talk about system users. They are not, at all, the same. 'root' is
    THE superuser, and all other users are just identities used to run things
    (can't login with them even, generally, and they have no special rights).

    Good luck.

    after you clicked on the help button (lower left) what question
    remains in your mind?

    are you familiar with users and groups in Linux? if not Chapter 9
    "Managing Users with YaST" in this URL will be helpful:

    http://doc.opensuse.org/products/ope...2.userman.html

    more basic and generic linux info on users and groups is all across
    the internet, like:

    Chapter 11. "User Accounts and User Ownerships" in rute's guide
    http://rute.2038bug.com/node14.html.gz

    http://www.debianadmin.com/users-and...-in-linux.html

    All the above advice is worth studying.

    They are used to be owners of files and run processes belonging to a part of the system. E.g. when you have an Apche server, it will run it's process under wwwrun. Thus it's files can be protected from e.g. all the files belonging to the user mysql (who is, as you might giess connected to MySQL). A sort of compartimenting. Same as for "normal" users: you are not allowed to use your wifes data, same wwwrun is not allowed to handle mysql data.

    The user nobody is to lower the power of remote root in e.g. NFS mounted file systems.

    This is all normal and nothing to worry about. Finding out more about them out of curiousity is OK of course. See the links of DenverD.
