LTSP-Build-Client Arch option not in Help
To find the options for a command you type: command --help It spits out a bunch of options that you can use to tweak the parameters of a command. On the --help for the ltsp-build-client script is the --dist option, which I thought can be used to install a different distribution that the one you are current using on the host. For instance:
sudo lts-build-client --dist lenny
There is another option, and it is not specified in the --help. The --arch option allows the specification of different architecture than your host. For instance:
sudo ltsp-build-client --arch -i386
If you are using a 64 bit host, you can install an i386 client file system with this.

Yes, I know it sounds funny. You can work locally from a remote location. I am specifically referring to use of LTSP. I am managing a server for a company, and I will be placing the server in an air conditioned server room; and I don’t want to sit in that room all day long. [...]

Mod security has features that go above and beyond a standard firewall. It will help to prevent denial of service attacks, and also can be used to block traffic based on realtime blackhole lists issued by Spamhaus and others. Mod security is apparently in the Debian repositories as well as Ubuntu. In the Ubuntu repos [...]

Server side includes allow for external html documents to be injected into a page prior to it rendering on the client web browser. The benifit of this is eliminating the need to repetitiously repeat code over and over again. If you include the same scripts, on each of your website pages, you can create an [...]

Apache2 implements a structured method of organizing and enabling/disabling modules and sites. The default apache2 host is automatically turned on in /etc/apache2/sites-enabled/, and it includes the virtual hosting option. Therefore, by default, virtual hosting is enabled. Create your virtual host containers in /etc/apache2/sites-available, and then enable them by issuing the command:
sudo a2ensite xxxxx.com
VirtualHost containers are [...]

I’m using LTSP to manage a server remotely in a local facility. I setup an LTSP server on the host machine, and will place it in an air-conditioned room to preserve longevity. I configured a machine, of much lower power, to PXE boot from the server. There are several nuances to setting up an LTSP [...]

There is a buzz that installing the Linux based Nvidia accelerated graphics driver is complicated. I consider it rather straight forward. First install build-essential, and the headers for your kernel. Those may appear to be some bigs words in the previous sentence, but it is really one line in a terminal window. Build [...]
