Delete a group notes
Groupdel can delete a group:
# groupdel groupname
In order to delete a user’s primary group (usually this is the group with name equal to the
username) the respective user must be deleted previously.
You can find more info in the manpages, but these will do in most cases.
user Linuxconf to manipulate users and groups
Linuxconf is a utility that allows you to configure and control various aspects of your system, and
is capable of handling a wide range of programs and tasks. Fully documenting Linuxconf could
be a separate book in its own right and certainly more than we can cover in this unit. So we’ll
focus on those areas that address common tasks such as adding new users and getting connected
to a network.
Linuxconf allows you to configure and control various aspects of your system. After configuring
your systems settings through Linuxconf, the changes are not activated immediately. You must
activate the changes by choosing File => Act/Changes from the pulldown menu in the GUI
version of Linuxconf, clicking on an Accept button in Web-based Linuxconf, or selecting the
Accept button in text-mode Linuxconf.
Linuxconf has four user interfaces:
1. Text-based: Using the same user interface style as the Red Hat Linux text-mode installation
program, the text-based interface makes it easy to navigate your way through Linuxconf
if you aren’t running X. If you are running X, you can switch to a virtual console, log in as
root, and type linuxconf to bring up text-mode Linuxconf.
Use the [Tab] and [arrow] keys to navigate the text-mode screens. A down arrow on a line
indicates that a pulldown menu exists on that line. The [Ctrl]-[X] key combination will
make pulldown menus appear.
2. Graphical User Interface (GUI): Linuxconf can take advantage of the X Window System.
Red Hat Linux includes a GUI interface for Linuxconf called gnome-linuxconf.
This document will display Linuxconf screens using the gnome-linuxconf interface, but
you shouldn’t have any trouble using the other interfaces with the instructions provided
here.
3. Web-based: A Web-based interface makes remote system administration easy; it can also
be displayed with the Lynx text-mode browser.
To use the Linuxconf Web interface, use your browser to connect to port 98 on the machine
running Linuxconf (i.e., http://your_machine:98).
Before you use the Web-based interface, you’ll need to configure Linuxconf to allow
connections from the machine running the browser. See the section called Enabling
Web-Based Linuxconf Access for instructions on enabling Web access to Linuxconf.
4. Command line: Linuxconf’s command-line mode is handy for manipulating your system’s
configuration in scripts.
