Did you check to make sure that your app *really* isn't binding to
port 8192? If it isn't, strace and netstat will be able to isolate
that problem.

More importantly, why does your app need to run as root? Running as
root and connecting to the internet is the most reliable way to ensure
you get compromised. If there are certain resources that *absolutely*
require root to obtain, then obtain them as early as possible
(definitely before starting the WEBrick server), then setuid down to a
saner user.
