Fun with ethtool

Time to be honest here for a minute. The open source community really has outdone themselves coming up with some very obscure names for packages. Let's take this list of packages for instance: emacs, gimp, gcc, mutt, grub, kyle rankin, parted, tar, mutt, vim. Nine times out of ten, a common person is going to look at that list and become utterly confused over what package does what. That's just the beauty (and beast) of naming software in the open source community. But every so often a tool comes across my screen with such a blatantly obvious name that I just have to run a 'man' to make sure my eyes are not deceiving me. In this case, it's ethtool. Yes, a simple name, for such a powerful utility. The name itself tells you what it does, an Ethernet Tool. Tada! That's it, ethernet tool.
