Asterisk GUI RPM

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.

[UPDATE] PXE booting qemu-kvm VMs with Windows DHCP and WDS

OK, so I now have a combination of things that will successfully PXE boot a Linux qemu-kvm virtual machine with Windows DHCP services and Windows Deployment Services (WDS). I'm using the gPXE CD ISO image to PXE boot the VMs. Now the WDS PXE process works as expected.

We have our WDS/RIS server setup similar to the following wiki article on the syslinux wiki:

Here's what I did on my workstation (I'm using Fedora 11):

PXE booting Linux qemu kvm VMs with Windows DHCP and WDS

[UPDATE]: Read the updated article here

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 (

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.

vmware server virtual machine will not power on - check the kvm linux kernel module

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.

Web Application Firewalls - Using Drupal with mod_security

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.

[UPDATE] - Sending Squid Access Logs to a MySQL Database


UPDATE: Due to a system crash and my poor backups, I no longer have the code for this post :( I'll try to reproduce it if I have time, but that's harder and harder to come by

OK, so I have the squid shaga engine code logging most everything to a MySQL table.

In order to successfully compile squid with this patch you will need liburi. You can download the pristine source for liburi here:
