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

In this example, is the host that should be routed via the VPN and "ppp0" is the name of the VPN network interface (ifconfig shows you the list of network interfaces). Can be a IP or domain name.

ip route get 2>/dev/null|grep -Eo 'src [0-9.]+'|grep -Eo '[0-9.]+'

Functions: get grep route

Instead of hard-coding in a check to scrape info from ifconfig based on a specific interface, do it in a more portable way.

This works really well if you switch between wired, wireless, bluetooth or even VPN connections. You can get your current IP in a script (since it'll be something like tun0 instead of eth0 or wlan1).

This uses a well known public ip address, but it doesn't actually connect to it, it just shows you the route it would take.
