I have some experience with programming, but I have very little experience when it comes to the security of programs. I've written a single-service server in Ruby which runs on a Windows XP computer to be used by a Linux computer in the same lab. The lab network is also behind a firewall, so there might not be a problem there, but I real...

We have an automatic build system that spits out packages, regression-tested & wrapped into a neat installer, ready for end-users to d/l & deploy.

The following code works fine as long as I don't try to run it through the distributed server. It doesn't get there... It runs fine out of delayed_job, runs fine if called directly.
