Flexnet License Monitoring With rrdtool
Some of you may know the commercial Flexnet Licencing Application
(©Macrovision). It’s a client-server based solution for managing the
usage of socalled Flexnet-enabled applications. You can hold licenses of
more than one product on one license-server. As you typically have to
buy licenses and licenses can be expensive it would be nice to have a
monitoring solution, to see the utilization of the precious licenses,
wether they are underutilized (so money is wasted) or are always fully
utilized (so that you can suspect that sometimes people can not do their
work, or only delayed) which is also a waste of resources. As far as I know there are commercial applications for performing
such reports, but again you have to spent money. Why not build a simple
system yourself, which shows the actual and past usage in an “MRTG style”?

How To Run Your Own Name Server With ISPConfig 3 And Fast Hosts
This tutorial shows how you can run your own name server for domains
that you register with fasthosts.com. Of course, this works with every
other
registrar as well, although the procedure might differ a little bit.
We
will use the ISPConfig 3 server as the primary name server and also
acting as the secondary. This may be suited best to a single server
setup. To do this, you need one server with ISPConfig 3 installed and a Fast hosts account.

How To Make An Ubuntu 10.04 Desktop Resemble A Mac (With Elementary,
Docky & Gloobus-Preview)
This article shows how you can change the appearance of your Ubuntu
10.04 desktop so that it resembles a Mac. This can be achieved with the
help of Elementary,
Docky, and Gloobus-Preview.
Elementary is a project that provides a popular icon set and GTK theme;
Docky is an interactive dock (like the one you know from a Mac) that
provides easy access to some of the files, folders, and applications on
your computer, and more; and Gloobus-Preview is an extension for the
Gnome Desktop Environment designed to enable a full screen preview of
any kind of file or directory.

Ghosting The Machine
This is a short but potentially extremely handy guide to ghosting
one Linux box to another (or simply making a full backup of a
desktop/server). You might have a small office where you customise one desktop
just how you like it and need to roll this out to N other PC’s or
simply want a backup of a server or desktop to another machine or even
to an image file. The main tool here is netcat which is extremely powerful and has a
multitude of other great uses that won’t be covered here.

Install Imule On Debian Lenny
When I write these lines, the latest
version of Imule is 1.4.6. But … It relies on packages version
(libgcj10, libstdc++6) that are released with the unstable (sid)
version of Debian. So either you upgrade Debian to unstable version
or you choose a lower version of Imule. I chose the latter: to
install an old version of Imule. I tested few of them and 1.3.5 seems
to work quite well with Debian Lenny (stable).
