VNC SSH TUNNEL PUTTY HOW TO
Restart the VNC Service: sudo service vncserver restartīelow steps illustrate how to connect to VNC Server through PuTTY(SSH) from Windows Machine. This document describes how to set up virtual network computing (VNC) tunnels using PuTTY to access virtual machine (VM) consoles, bypassing XenCenter. From a Linux (or Mac) computer to one of our Linux computers using an ssh tunnel and VNC. This gives you the advantage of running the vnc server only on the loopback interface on the remote side. then connect to 127.0.0.1:590 2 with your local vnc client. On CentOS, edit /etc/sysconfig/vncservers file: sudo nano /etc/sysconfig/vncserversĪdd the option “ -localhost“: VNCSERVERS="1:arbab 2:ali" VNCSERVERARGS="-geometry 1024圆00 -localhost" VNCSERVERARGS="-geometry 1024圆00 -localhost" Try the following: start the vnc server on ip 127.0.0.1, port 5901. On Linux, you can choose from many options, including vinagre, krdc, RealVNC, or TightVNC. On macOS, you can use the built-in Screen Sharing program, or can use a cross-platform app like RealVNC.
In this example, I am using CentOS 6.2 as VNC server and VNC Viewer & PuTTY as VNC client on Windows 7. The VNC client you use must support connections over SSH tunnels: On Windows, you can use TightVNC, RealVNC, or UltraVNC. If your VNC client doesnt have ssh support compiled in, you will have to use an additional step to open the tunnel from your SSH client. Once, we connected then all the VNC data is unencrypted and hacker could sniff our VNC session. It is better (safer) to start VNC server only on 127.0.0.1(localhost) and tunnel it over secure SSH tunnel (For this,there are options in Putty).
Before starting this tutorial, please read this post, to learn more about the VNC Server setting that we are using in this tutorial.īy default, VNC is not secure protocol.VNC uses encryption during initial connection and login (passwords are not sent in plain-text).
