hi,
i want to install xpde on my fedora core 3 linux. It is saying to disable the selinux. He gave instruction to disable in fedora core 4 where
>>Disable SElinux
SElinux is a security add-on that often interferes with shared library execution, and is usually the cause of the "your session lasted less than 10 seconds" error. Fedora installation enables SElinux by default, so you probably need to turn it off. Go back to the text editor and open /etc/selinux/config. Change the entry for "SELINUX=enforcing" to "SELINUX=disabled". Save and close the config file.

But in fedora core 3 there is no /etc/selinux
so i am getting the above error.
Plz tell me how to disable the selinux in fc3

In general, you shouldn't set SELinux to disable, as you will need to relabel all files on the drives to enable it again. You can temporarily set it to permissive instead.

As root, issue the command:

You should also be able to to set the permissive option by selecting menu System->Administration->Security Level and Firewall.
