Psst. Open beta.

Wow, didn't really expect you to read this far down. The latest iteration of the site is in open beta. It's a gentle open beta-- not in prime-time just yet. It's being hosted over at UpGuard (link) and you are more than welcome to give it a shot. Couple things:

  • » The open beta is running a copy of the database that will not carry over to the final version. Don't post anything you don't mind losing.
  • » If you wish to use your user account, you will probably need to reset your password.
Your feedback is appreciated via the form on the beta page. Thanks! -Jon & CLFU Team

A grep against ethtool to look for common errors and packet loss statistics which network drivers report in their private data, which is queried with ethool -S. This is the current grep used in xsos (https://github.com/ryran/xsos), which I originally contributed and has been improved by the community over time.

ifdata -pN eth0
ifconfig -a | awk '/Bcast/{print $2}' | cut -c 5-19

Why use many different utilities all piped together, when you only need two?

ethtool is used for querying settings of an ethernet device and changing them. In this example I setup 100 Mb/s full duplex on my Linux Box
