104 Appendix D. Troubleshooting Your Installation of Red Hat Linux
D.4.7. Your Printer Will Not Work
If you are not sure how to set up your printer or are having trouble getting it to work properly, try
using the Printer Configuration Tool.
Type the redhat-config-printer command in a shell prompt to launch the Printer Configura-
tion Tool. If you are not root, it will prompt you for the root password to continue.
D.4.8. Problems with Sound Configuration
If you do not have sound after your installation, you may need to run one of the sound configuration
utilities.
To run the graphical sound configuration tool (Red Hat Sound Card Configuration Tool —
redhat-config-soundcard), from the Main Menu click on System Tools=>Sound Card
Configuration.
To run the text-based configuration tool, as root, type sndconfig in a terminal window.
Note
sndconfig must be run in runlevel 3. More information about runlevels can be found in the Official
Red Hat Linux Reference Guide, in chapter Boot Process, Init, and Shutdown.
If the sound card configuration tools do not help, you may need to select the Enable sound server
startup option under Multimedia=>Sound in the GNOME Control Center.
To do this, click on Panel=>Programs=>Settings=>GNOME Control Center to launch the
GNOME Control Center. In the GNOME Control Center, select the Sound submenu of the
Multimedia menu. On the right, a General sound menu will appear. Select Enable sound
server startup and then click OK.
D.4.9. Apache-based httpd service/Sendmail Hangs During Startup
If you are having trouble with the Apache-based httpd service or Sendmail hanging at startup, make
sure the following line is in the /etc/hosts file:
127.0.0.1 localhost.localdomain localhost
