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.

LibreOffice 5.0 Right Around the Corner, Guided Tour of LibreOffice

  • LibreOffice 5.0 Right Around the Corner
    Major release LibreOffice 5.0 is due next Wednesday with a lot of new features. Italo Vignoli today posted The Road to LibreOffice 5.0 in which he looks back at all the added features since January 2015 with version 3.3. Today's summary shows "the impressive amount of new features added to LibreOffice since version 3.3." LibreOffice 3.3 was released in January 2011. This release was significant in that the development and management of LibreOffice had come together in a short time and put out a release that brought several new features. SVG support, easier title and page formatting and numbering, improved ergonomics in Calc, and Microsoft Works support were among the newest features added by The Document Foundation.
  • A Guided Tour of LibreOffice
    I have been using LibreOffice since it was called Star Office and all documents opened in a tabbed interface, as in most modern spreadsheet applications (anyone remember those days?). From those early days until now, I have considered Star Office/OpenOffice.org/LibreOffice to be an excellent, if not superior, tool compared to many on the market.
