10.5: Screen share with multiple Macs behind one NAT
For people familiar with SSH, it's a lot simpler to use SSH port forwarding (the -L option) to achieve this. It also means not having to permanently alter your system configuration.
10.5: Screen share with multiple Macs behind one NAT
On Windows, I've never used VNC without SSH, as (most?) VNC servers have no protection against brute force attacks (and thus allow for an unlimited number of attempts to guess the password).
10.5: Screen share with multiple Macs behind one NAT
Screen sharing requires both the login name and password then rejects login after three failed attempts.
10.5: Screen share with multiple Macs behind one NAT
I did some testing with Screen Sharing enabled for standard VNC clients, like to access a Mac from non-Mac OS X systems. (In System Preferences, Sharing select Screen Sharing, and then click Computer Settings. Here, one can enable and set "VNC viewers may control screen with password".)

tunneling through ssh also gives the added benefit of encrypting the connection, as a vnc connection on it's own is quite insecure.

It's wonderful that you suggest using SSH to do screen sharing. However, there are some of us out there that have no clue how to accomplish this. Why not fill us in so that we can all share in your suggestion.

You connect to your ssh exposed computer with ssh myuser@myhost.com -L 5900:10.0.1.xxx:5900 where 10.0.1.xxx is the private IP (behind the NAT) of the computer you want to VNC to. This binds the remote port 5900 to your local port 5900 so when you VNC to vnc://localhost you will be able to connect to the remote computer. |
