Unit 4: Configuring Desktop




          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.
