VM rop tunnel howto

From Wsms

How to tunnel from your VM to the classroom server.

Before you start, you might want to change your VM's hostname by editing /etc/hosts and /etc/sysconfig/network as described in 20061108#Set_a_host_name_on_your_virtual_machine

Tunnel the connection for usermin and launch firefox with something like:

[ggeller@ws05 ~]$ ssh -f -N -L 20001:localhost:20000 georgeg@rop.ncc.sdccd.net
...
[ggeller@ws05 ~]$ firefox localhost:20001

Note that we choose 20001 for the port to listen to on the VM because port 20000 is already occupied with our own local copy of usermin.

So we have ssh listening on the local machine listening on port 20001, encrypting the information and forwarding it across the LAN to port 20000 on rop.
