Sometimes my lpd is blocked launching the following error:

StateMessage /usr/lib/cups/backend/lpd failed

After restarting cups the problem is still there.

I found a simple solution, just change the /etc/cups/printers.conf file. First stop your cups daemon:

$ sudo service cups stop

Then you should change the file:

$  sudo sed -i -e '/StateMessage .*lpd failed/d' \\ 
    -e 's/State Stopped/State \\
    Idle/' /etc/cups/printers.conf

Then restart your cups daemon:

$ sudo service cups start

It works properly on Fedora

If you want to install XFCE desktop on Fedora 15, you only need to execute the following command:

$ sudo yum groupinstall XFCE

After executing the command, you can choose XFCE using your default session manager.

Fedora and other Red Hat based Linux distros can use chkconfig for enabling/disabling services at boot time.

If you want to enable Apache at boot time, just execute the following one command:

$ sudo chkconfig httpd on

Another example could be the next one:

$ sudo chkconfig mysqld off

Also it's possible to display the status for all services:

$ sudo chkconfig --list

Ubuntu and Debian users know that /tmp directory will be deleted after booting. However, this scenario is different on Fedora.

Fedora uses a program called tmpwatch, which removes files which haven't been accessed for a period of time. This program is invoked from cron through the script /etc/cron.daily/tmpwatch.

By default, Fedora removes those files that haven't been accessed for 30 days. Obviously, you can change the value editing the mentioned script.
