Linux: Headless Ubuntu Torrent Home Server

So it got to that time of the year where I feel the itch to upgrade my aging home server. I assessed the situation and realized that, for what it does, my current server does not need any kind of hardware upgrade. So I just decided to rebuild it with Ubuntu 11.04 64 bit and change up the server software a bit to be more accessible to my wife as well as to be a bit more modern (torrentflux and derivatives have been dead for a while now).

In working on a production issue with my company’s flagship SaaS product I worked with some of the brilliant F5 engineers to isolate one web server in the load balanced pool which was intermittently failing. The F5 engineer recommended a health monitor that does more than just poll for a static page. He suggested we implement some kind of soap call to make the application pool do some work and return a result (I guess in case the IIS application pool is misbehaving but not down). So I worked with one of our developers to do just that but ran into some caveats which required yet another custom health monitor.

In seeking a solution I ran across this gentleman’s blog with a custom external monitor but found that it didn’t really work. The solution to make it work was simple (as I explained on his blog in a comment). I went ahead and extended it to be more environment generic.
