psutil is probably clean on Linux. However, using the subprocess module to run ifconfig -a and check for tun0 / utun0 should get you compatibility with both Linux and Mac. Note that if I'm running a Linux in a VMware, and it's hosted on a Mac, and the Mac has one of my VPN's up, then the Linux doesn't have a tun0, but it can still see stuff only accessible via that VPN. For that, it might be better to try ping'ing some host that's behind the VPN. In a way, that's a better test anyway. -- https://mail.python.org/mailman/listinfo/python-list
