Before I do not use TeamViewer, recently spent more, especially easy to use, a bit addictive, even where the family can RTX, great.
Then he made a start.
There is no good alternative to it? Some recommend sunflower, sunflower apparently based on profit, I do not want to enter another pit.
By trial and error, finally found a fully free (but not open source) solutions.
1. How to find a home computer from anywhere. I had found this before. ZeroTier One. https://www.zerotier.com
The main principle is ZeroTierOne communication + P2P virtual network card driver, it can be pulled two all complicity in the device with a virtual network, support win linux mac. No charge within 100 units. Such home computer can assign a ZeroTier One of the fixed network IP.
Private virtual VPN IP ZeroTier One of my assignment.
2. How Remote Desktop?
I tried windows remote desktop, but windows Remote Desktop does not support the H264 compression (RDP10 support, no available version), fast Internet connection when it comes to the line, the network card is completely Rom, 640 * 480 resolution will not work.
I finally found the only area of free software available: NoMachine. https://www.nomachine.com/
NoMachine supports H264, VP8, MJPEG three compression. Point lower image quality and resolution, VP8 H264 both compression very smooth. The default setting NoMachine's a little unfriendly, after adjustment to adjust their own hands, happy extent not lost TeamViewer (very smooth, you can put a movie).
NoMachine settings:
Finally, to a ZeroTier + NoMachine family portrait.
Farewell TeamViewer！
