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

You don't need this command often and there are other ways to test output but if you want to be sure if your router and ethernet card are working this is one way.


There are 2 alternatives - vote for the best!

For all newbies (like me) out there, please note you should request a new IP to a DHCP server, with either dhclient or dhcpd or whatever equivalent.

That's IF you're using dynamically-assigned IPs...some people prefer static IP assignment (including newbs).
