VPS2 User Permissions
Users on your VPS2 can have different permissions, which grants or denies them access to use
Shell, FTP, E-mail, or Web space. These permissions can be set or changed when you
Manage User Accounts.
E-mail Permissions
In order to use a remote E-mail client (such as Microsoft Outlook) to send and recieve E-mail, a user must have
E-mail permissions. E-mail permissions allow a user to remotely send messages with SMTP, and to use POP or IMAP to
download messages. When adding a user with the vadduser command, E-mail is enabled by default.
NOTE: Users who wish to use IMAP services to check and store E-mail
need to have both E-mail and FTP permissions.
Select/deselect services [e-mail ftp shell web]:
To remove E-mail, type e-mail at the prompt shown above. You will then see the same list as above, except
the e-mail entry will be removed.
Select/deselect services [ftp shell web]:
You can re-add E-mail to the list by typing e-mail at the prompt.
To modify E-mail permissions for a user who already exists, you can edit the /etc/group file. A user with
E-mail permissions needs to be listed in the pop and imap group member list. Below is an example
of the pop group entry with two users (admin and test).
pop:*:82:admin,test
FTP Permissions
To allow users to use FTP to copy files to and from the Virtual Private Server, they must have FTP access. You
can allow or disallow FTP access when you set up the user with the vadduser command, or you can add or
remove the user from the ftp group in the /etc/group file. (see E-mail permissions above).
NOTE: Users who wish to use IMAP to check and store E-mail messages
must have FTP and E-mail permissions.
Shell Permissions
Granting VPS users shell access gives them the power to connect to their filespace on the server and work
directly with files and run commands. When you give a user shell access using the vadduser tool, you will
be prompted to select a shell for the user from a list. Because the shell access is defined at the end of the
user's entry in the /etc/passwd/ file, you need to use the pw command to change the default shell
or to disable or enable shell access. A user without shell access will have /sbin/nologin as their
shell.
NOTE: Any user with shell permissions will be able to send and
recieve e-mail messages using a local E-mail client program (such as pine). In order to use a remote
client program (such as Microsoft Outlook), the user must also have e-mail permissions.
Web Permissions
Web access permissions grants a user space to publish web content. It does not have any effect on whether or
not a user can view any web material. A user with Web access permissions turned on will have a www
directory in in their home directory with locations for CGI scripts, logfiles, and web pages. By default, a
web user will be able to view their own pages by going to the VPS primary domain name followed by a tilde
(~) and their username, as in the example below.
http://YOUR.DOMAIN.NAME/~username
There are a number of different ways you can set up Web space for a user, as well as being able to associate
domain names with the Web space. For more information see
Sub Hosting Web Sites.
