How to securely control another Mac over the internet
Authored by: martinw on Sep 11, '06 01:39:07PM

Sean,

This is a great tutorial, thanks. I am having trouble getting it to work - I am soooo close. I think I followed your direction to the letter.

The SSH Reverse tunnel appears to set up correctly from the "client" computer (the one which is to be controlled).

When I run Chicken of the VNC on the "administrator" computer (computer intended to do the controlling), connecting to localhost, I get the error: Authentication Failed. That sounds like it would be a simple password issue. But in your tutorial, you say not to even enter a password when connecting to localhost.

I have also tried connecting to localhost, AND using the password which the Client computer entered under "VNC viewers may control screen with Password." This still results in the same error message: Authentication Failed.

The SSH tunnel appears to be open and working.

Here is the setup if it helps:
"Administrator" computer (PowerBook):
- connected to internet directly via cable modem
- no router, no NAT
- running chicken of VNC
- Remote Access is enabled in SYS PREFS
- "Dummy" account established

"Client" Computer
- Connected to internet as follows: Internet -> ADSL Modem -> Airport Express -> Client Computer (MacBookPro)
- Successfully stablished reverse ssh tunnel to "dummy" account on "administrator" computer.

If you are still monitoring this thread.... any suggestions? Would it be anything to do with the fact that the "client" computer is behind 2 routers (ADSL Modem and Airport Extreme)?

Thanks so much in advance! :)

Martin

Actually, cancel that. We did get it working in the end. I dont know what the problem was, but now its going great. Sorry for the false alarm.

I had the same problem but found out there was already a vnc client that was using port 5900.
When I changed the port in the tunnel and in the client to 5800 it worked again. Even easier: I restarted the vnc client, and all was well. You probably did the same.
