QNAP and Torrent

I noticed a noticeable amount of Torrent traffic both from, and to, my QNAP NAS server. It turns out, if you enable the Download Station application, it starts doing all sorts of Torrent discoveries on its own. I have no idea why, so for now, I have simply removed the application entirely. I noticed this by doing a

$ tcpdump port 6889

Apache Traffic Server recipes

Apache Traffc Server is a high performance, customizable HTTP proxy server. This is a collection of small "recipes", showing how to accomplish various tasks. This cookbook is work in progress, I haven't quite decided yet how I want to handle this "documentation". Perhaps it belongs in Apache official docs, but for now, I find it easier to use the tools I'm used to here on ogre.com to maintain this.

Traffic Server is finally here

Finally! We pushed the Traffic Server code to Apache SVN today! This is definitely a momentous occasion, this has been in the works for ages, and it took a lot of work and patience to happen. You wonder, why did we bother? Well, you are right, there's plenty of proxy server alternatives out there, Squid, Varnish, NginX and so on. But, we think we have a platform we can build something on that will be better than anything out there (that is free at least). Why? Well, we have

  • A scalable threaded + asynchronous state machine model. On a typical setup, 2 or 3 threads per core is enough to drive a large amount of traffic.
  • Feature-rich HTTP/1.0 and HTTP/1.1 support. We fair well in various tests like CoAdvisor.
  • Plugin architecture, making it easy (well, easier) to extend and customize your server.
  • Well documented.

I'm not saying it's perfect (far from it), but the hope is that Open Sourcing this will attract an active developer and user community around the software. So, you want more information? Well, besides visiting us on #traffic-server on irc.freenode.net, here's a bunch of links with some useful information:

Please join the mailing lists (see the Incubator page), talk to us on IRC, or just take a look at the code.

Update: Mark Nottingham (on our team now!) has a blog post with some interesting history and thoughts on TS.
