Who controls what in the virtual UNIX server system is
often confusing. The illustration below describes the privileges of the root
user, the Administrative user, and a user.
Hierarchy of access
|
THE PHYSICAL BOX
somewhere on Earth, having a UNIX OS installed on it, controlled by someone
having ROOT “/”access to partition the virtual server
accounts. |
|
The VPS v2 Virtual Server root user
The actual virtual server account owner who logs in as root at /root
(not /)
in the file system. This person also has an Administrative User ID and
password. |
|
The VPS v2 Virtual Server
administrative user
An Administrative User has shell access, user management, file management,
and log management privileges for multiple users, but not root access to the
entire filesystem. |
|
The VPS v2 Virtual Server user
A user who (by default) logs in as username at /home/username.
who has one or more of the following privileges: shell, FTP, e-mail, Web. |
The VPS v2 Virtual Server owner has two usernames: one for the root login
and the other for the Administrative User login.
As the root user you have superuser
privileges in controlling all resources (files, users, processes, etc.)
belonging to the VPS v2 Virtual Server. You can log in as root using SSH, SFTP, and iManager. By default—for security reasons—you cannot use
Telnet, FTP, POP or IMAP. (The Administrative User has these privileges.)
As the Administrative User, you also have membership in
the FTP group. Additionally, you have shell access and membership in the POP
and IMAP groups, giving you the ability to send and receive mail. You will
receive mail for root.
As Administrative User, you can use the following sudo commands. See the /usr/local/etc/sudoers file for a complete
list of commands.
