		<description><![CDATA[EncFSVault provides a replacement for Apple&#8217;s FileVault. There are a lot of issues with FileVault. Personally I don&#8217;t like any proprietary software for security sensitive storage of my data. But the main reason I was not able to use FileVault was the fact that FileVault still doesn&#8217;t provide support for case sensitive HFS+ file systems [...]]]></description>

		<description><![CDATA[In this tutorial I&#8217;d like to describe how to create an extensive sendmail wrapper for a web server to monitor all sent emails and throttle daily sent email volume by the senders original UID (user id). This is useful if you e.g. run PHP in CGI-mode with SuExec, that is: all customers run their scripts [...]]]></description>

		<description><![CDATA[I have updated the process hiding kernel patch described in my previous post. The following patch was created for a vanilla kernel 2.6.27.10 from kernel.org. You should be able to patch also future kernel versions as it is a super simple single-line patch. Just modify one line in the proc_pid_instantiate method of fs/proc/base.c. diff -U8 [...]]]></description>

I describe in a short tutorial how to painlessly setup a simple sendmail wrapper to accomplish this. This has been tested on a Debian Lenny 5.0 system running PHP [...]]]></description>

		<description><![CDATA[Currently all Linux kernel security patch projects seem to be sleeping. There is no useful kernel patch that provides us with a decent patch set allowing us to strengthen the Linux kernel. Some years ago I was using Grsecurity, a wonderful solution to enforce security on 2.4.x kernels at that time. The project seems to [...]]]></description>

If you provide web hosting services for your customers you have to provide them with a lot of features to make them happy. The main requirement for any hosting provider is PHP, probably the widest spread web scripting language out there. Some customers [...]]]></description>
