Wum has it's own website which can be found at http://wum.rfc2324.org

cisco-stats is a bunch (at the moment two) scripts with what you can get an overview about the vlan infrastructure and port usage on your cisco devices.
For further information see the my cisco-stats site.
The mailquota viewer tools collect (filesystem) mailquota information and present them to your users via a CGI script.
Each user gets a personal report, so nobody can see information about other people.
The authentification is done via Apaches Kerberos module.
If you are interested, you might want to see a screenshot from the CGI script.
(Allthough the text presented on the screenshot is in german, it is easy to localize it for your needs.)

Nice little tool to convert invoice information into a nicely formatted \LaTeX file to help people on writing invoices which look good.
It's recommend to have make and pdflatex installed to simplify things even more.

I've made some patches to enhancde it.
I found the munin plugin from Rodolphe Quiedeville
which used the openvpn status file as source for the number of currently connected clients.
I liked this approach and modified the plugin to support multiple instances per server.
I've added WTMP support to OpenVPN to let it write a wtmp file with all it's connections.
You're able to specify a two-digit server_id per OpenVPN instance to let many
OpenVPN instances write to the same file but still be able to distinguish between them.
Neil Brown wrote some nice patches which enable OpenVPN to push only one IP address to a Windows client,
when using tun devices instead of the usual /30 subnet which wastes 4 address per client.
I've updated them to fit to the current OpenVPN version. (v2.0.9 and current svn revision 2171).
This introduces the new config option net-type.
I've also made up a patch against OpenVPNs makefile.w32 which is used when building a Windows binary on a Linux box using mingw32.
The patch introduces usage of make's advantages and cleans up the makefile.
There are also Makefiles for building liblzo2 and openssl for Windows using mingw32.

I wrote two small patches for the setup_harddisks tool of FAI.
One patch changes setup_harddisks behaviour if Xen Dom-U devices like /dev/xvda1 are found but no correspondig "disk" like /dev/xvda.
The patches version of setup_harddisks will skip partitioning and just put the filesystems specified in the disk_config file on the devices.
This is rather useful when you want to put every block device of the Dom-U as a single device (like LVM volumes) into the Dom-U, which has the big advantage that you
can access the filesystem from Dom-0 if your Dom-U is dead...
The second patch makes setup_harddisks honor if you wrote 'ext3' into the options column in your disk_config file.
Up to now you had to write '-j' there if you wanted 'ext3'.
setup_harddisks Xen Dom-U patch
setup_harddisks honor ext3 option patch
I've added a new configuration option --without-full which will prevent llgal from generating a link to the full size images from the scaled down images on the HTML slides.
This comes in handy if you do not want to put the high resolution pictures on the net, but want other to have a look at your picturs.
This patch has been included in Llgal in february 2010. The option has been renamed to slide_link_to_full_image .

I made up a list of packages I like to have around on my machines. Maybe you get inspired by it.
I've a made up a small hands-on howto to build your own OpenVPN.exe for Windows and created some Makefiles
which let you easily build liblzo2, openssl and openvpn using mingw32 build environment on a linux machine.

After struggling a bit with getting this to work, I've written a small howto to accomplish the above task.
