[ILUG] Debian and GRsecurity

[imduffy]

Hi Guys,

I was wondering if I could get some help with the grsecurity kernel. I am
having issues installing gradm.

I installed the grsecurity kernel binary for debian squeeze from this repo:
http://kernelsec.cr0.org/ it works perfectly.

However I wanted to enable RBAC with gradm, I downloaded the latest gradm
source code from the grsecurity website and compiled it however when I try
enable it I get the following error:

[duffy at pulse:~] # sudo gradm -E
Read access is allowed by role default to /sys, the directory which holds
entries that often leak information from the kernel.

There were 1 holes found in your RBAC configuration.  These must be fixed
before the RBAC system will be allowed to be enabled.

If I try to use gradm -D I get the following:

[duffy at pulse:~] # sudo gradm -D
Password:
You are using incompatible versions of gradm and grsecurity.
Please update both versions to the ones available on the website.
Make sure your gradm has been compiled for the kernel you are currently
running.

[duffy at pulse:~] # uname -a
Linux pulse.tuts4tech.net 2.6.27.29-4-grsec #1 SMP Sun Aug 16 12:21:49 UTC

Any advice?
I have tried using other versions of gradm however I have had no success.
