Grsecurity Patched Kernel Install Script For Redhat based Pentium 4 servers

Filed under
Howtos

After a lil work getting the config right for s hosting/shell server I finally came up with the script that will patch, compile, and install the gresecurity patched kernel. You just run the shell script and it will download the kernel and patch, patch the kernel, download the config, and then compile and install.

The config I got made up is for Pentium4/Xeon/Celeron based servers. It includes all necessary option for an average pentium based server with single processor. The grsecurity level is set to low along with proc restrictions where users can see only their processes, I find the proc restrictions more of a convenience then actual security procedure because shell users do not have to go through all the processes to find theirs nor do they have to do ps -u so it is a pretty handy feature.

All xtables, iptables, and such are enabled. Lots of generic options are selected but nothing that is not needed by at least some machines.

I have ran this script successfully on a fedora and 2 centos servers and it done just fine. As far as stricter security options and pax goes a lot of them do not work well with your typical hosting server. The way it is now it is very secure and protected against local exploits while stoill being totaly functional and not over restrictive.

Nobody should have any problems what so ever if you are running a pentium 4 based single cpu server with 512mb-2gb ram. Let me know if anyone has any problems or needs any help.

I figured quite a few people could find this handy, not just beginners but for busy admins who do not have the time to do all this and sit and watch it. It is nothing but a simple sh script, there is no shellcode or any other code involved.

Salix Fluxbox 14.1 Is a Lightweight Modular Distro Based on Slackware

Along with the Openbox version of Salix, the Fluxbox edition is one of the lightest iterations available in the series. Unfortunately, it's not exactly on the list of priorities for the developer and it's been trailing a little behind, but now it's ready. Salix is one the few very active distributions based on Slackware, which is a famous and very stable operating system that has been around for quite a while. It's rather different from what everyone else is doing because it is a modular system and it has a rolling release model. Read more
