KVM (Keyboard-Video-Mouse) is the generic name for remote access technology to the monitor, keyboard and mouse of a server. Such access is not dependent on the operating system, so it works even when the operating system has crashed on a VPS. You can also boot the system from a CD/DVD, setup BIOS, etc..
VNC is a specific protocol that allows this remote access.
Access via VNC is not designed for daily usage, but mainly for emergency situations when there is a failure of the operating system or to install an operating system from a CD/DVD. Working with the server is much more comfortable when using the usual methods:
- for a server with a Linux operating system – via SSH, for example via the Putty program
- for a server with a Windows operating system – via a Remote desktop (RDP, Terminal Services)
Which Client Should You Use?
To access the server by using this method, you need to install a VNC client program onto your PC. For Windows, we recommend using the VeNCrypt program. We recommend ssVNC for Linux.
Communication via VNC is encrypted (VNC over SSL, the SSL version must be 3.0). You have to use a client program, which supports this SSL version. Most freely available programs for Windows do not support it (eg. RealVNC, TightVNC, TigerVNC).
For the SSL, a certificate named vm.wedos.net is used. Certificate fingerprints for your inspection:
- SHA1 Fingerprint C8:C2:23:33:45:9D:2C:44:F4:3A:CE:9C:71:4B:B0:E1:3B:8F:5C:FD
To connect to your server, you need the destination address, port, and password. Everything will have been sent to you in an e-mail with information about setting up a virtual server.
