Tunnelling a Headless VM Through an SSH Tunnel
I was doing a web project for a client recently where I needed to administer a server VM but only had access to the machine via port 22 (SSH).
I setup the machine to run as a Headless VM but, because of the security restrictions, I needed to configure an encrypted tunnel created through an SSH connection. For more information on setting up a headless VM for VRDP, see my previous post Running a Headless VM over VRDP.
# First you need to ensure that your Virtual Machine has VRDP enabled. VBoxManage modifyvm "VM name" --vrde on # Specify a port for the VRDP service. Here, I have chosen port 10000. VBoxManage modifyvm "VM name" --vrdeport 10000 # Start VM on Server Host (from ssh prompt) VBoxManage startvm "VM name" --type headless # From a Cygwin prompt on your machine, create an SSH tunnel ssh -L 10000:localhost:10000 firstname.lastname@example.org # From cmd prompt on your local windows machine mstsc /v:localhost:10000
