Hello everyone.

I've started using ping at first, just because it was the simplest and fastest solution, until I do the JSON validation. You're right, the program thinks computers are offline only when it reads "Host Unreachable" and I will fix it to work better.

I've decided to not make a webserver, because to use it I still need to log in VNC server (If I'm not connected to the local network). That's way I've made the remote control from Telegram. Now I can control and inspect my machines very easy. I will upload the updates until end of the week after I made the telegram bot more convenient  to use.
