View Full Version : Selinux Manager

Tyring out F18 alpha, generally ok so far. But what is the name of the management tool to install via yum? I need to turn off (and on) selinux while testing some stuff. :confused:

setenforce [ Enforcing | Permissive | 1 | 0 ]
should be installed already.

I have been doing that this evening (trying out F18 Alpha). I had been reading the Dan Walsh Blog today and there was mention of changes in SELinux in F18 . I downloaded the iso and gave the live cd a shot and I then decided to accept my fate :) and install to hard drive.

I then attempted to download the updates (as I do after a fresh install ) but SELinux warned me that there were too many packages to unwrap, or something similar. I am no expert on this, but I thought that perhaps SELinux has a limit set for that and my work around was to download the updates in small chunks at a time and this did work, after some time I selected all packages and everything went smoothly.

Again I am not an expert here but as far as I am aware SELinux attaches labels to files so if you switch it on and off after changing files this may cause a problem, someone correct me if I am wrong.

To access the yum installer , go to main menu, system tools, and yum extender. Hope this helps you in some way :)

You can set enforcing to off (i.e set it to 'permissive'). If you disable selinux altogether then when you enable it it has to relabel the filesystem.

I understand the implications (I think ) of disabling/enabling.
But in previous releases, there was a gui app that, among other things, would do this for you. No I cannot find it!

I think in F17 it's called policycoreutils-gui

Thanks, that did the trick.

A name like selinux-manager would have made more sense :dance:

But you have to have a reasonably powerful machine if you start messing with the policy rules.
Every time you check or uncheck one of those boxes, AFAIK all policy is recompiled.
