What is a free remote control software?

Question

Freeware

Greetings!
Guys, please tell me a free program for remote computer control (something like TeamViewer ), which can be used for commercial purposes :)
Ie . there is an office and about a dozen computers that need to be serviced remotely (sometimes from a LAN, sometimes not
).

Answer 1

any rdp client.
You can also use ssh or telnet if you are friends with the console.

Answer 2

if there is a vpn connection (if they are not on the same subnet), then you can use RDP, I advise you this way, since this is a really cool thing. and teamviewer is slow, because you sit through their vpn

Answer 3

VNC - Open cross-platform solution. To knock from the outside - you need a VPN.
