At 23 years, gnuplot is one of the oldest free and open
source programs out in the wild world. It runs anywhere and
everywhere. It's an interactive, text-based plotting program that's
quite easy to use, and yet can produce surprisingly complex plots.
Many features of gnuplot are shown in a live demo.

This talk is a continuation of my previous talk on localhost
troubleshooting. In this talk, however, I will discuss common methods
to troubleshoot networking problems on Linux. I will work from Layer 1
(physical connection) all the way up to routing and if time permits,
some DNS troubleshooting as well.

Every year or so you hear about how the Internet is about to run out of IPv4 addresses. When that happens we will all need to be able to migrate to IPv6. In this talk Owen will discuss what IPv6 is and cover how to use IPv6 from a sysadmin perspective.
