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

Shows how many Windows and Linux devices are on your network.

May add support for others, but that's all that are on my network right now.

Know a better way?

If you can do better, submit your command here.

What others think

Believe there is an error, nmap output is sent to /tmp/os, while the cat is done on /tmp/network. Both files must be the same.

This will work if you substitute /tmp/network for /tmp/os in your command.
