If you have recently updated to the most recent mod_security RPM from Fedora and you are running Drupal, you've probably noticed that certain things don't work correctly. Most specifically, some of the system CSS pages and tabs look funny, and if you're using the pathauto module with the default URL aliases you are probably get a Forbidden (or HTTP 403) when you try to access your content.

Last night I wanted to record some things (for personal use only) coming out of the stereo mix on my Linux workstation (currently running Fedora 11 x64). In the past I've been able to use Audacity (http://audacity.sourceforge.net/) - the awesome open source and free audio editing software available for Linux, Mac, and Windows. For some reason I wasn't able to get Audacity to pick up the stereo mix as an input so I searched around to find out how I could record the stereo mix coming out of a Linux workstations soundcard. Here's what I found ...

So I've wanted to try out Google Chrome on Fedora, but I'm kind of a purist in that I only like to install software on my workstation that comes packaged in an RPM. Many times if software is not available in RPM format I'll build my own with our in-house Koji buildsystem. Koji is the same system that the Fedora Project uses to build it's packages (http://koji.fedoraproject.org).

So I was building RPM packages for the Asterisk GUI when it was the 1.0 branch. I haven't done work on the package in quite a while and I finally got around to building some new RPM packages for Fedora.

These Asterisk GUI RPMs are from the current SVN 2.0 branch and the SVN revision number is in the package name (e.g. RPM asterisk-gui-0.4986-3.fc11.noarch.rpm is SVN version 4986).

I try to do basic testing with the RPMs after they are built and they WorkForMe(tm) before I post them. YMMV.

So VMware Server 2.x on Fedora 11 has been driving me nuts. I recently re-imaged my workstation and decided to ditch VMware Server and give Linux qemu-kvm a try since it is now the default hypervisor in Fedora and will be the standard hypervisor going forward in Red Hat Enterprise Linux (http://www.redhat.com/rhel).

We are an almost exclusively Windows shop so we use Windows DHCP servers and Windows Deployment Services (WDS/RIS) server to image all of our workstations and servers via PXE booting. If we were using an ISC dhcpd server things would probably have been a lot easier. Below I describe how I get things (partially) working.

I've had this a couple of times now in the last few weeks. I wanted to try out the Linux KVM virtualization hypervisor that comes with Fedora 11 since VMware Server 2 is giving my fits on F11 x86_64 so I installed qemu and all the supporting packages via yum.

I realized that I can't do some things with KVM that I can with VMware Server so I'm putting up with the signal 6 crashes every week or so and went back to VMware Server 2.0.1 for Linux. In order to get that running I had to apply some patches to get the kernel modules compiled but that's been done for a while.

First some background about web applications firewalls for the uninitiated. If you already know what a web app firewall is then you can skip down to the bottom of the post for some mod_security rules that will help you with Drupal Views, the GMap module admin pages, and Google Webmaster Tools.
