How to securely control another Mac over the internet
Authored by: The Cardinal on Sep 20, '06 03:48:21AM

Rereading that post it seems a bit wishy-washy. What I am actually asking is this:

1. Should I be able to control the client even if the admin and client computers are accessing the internet through the same router?

2. Do I need to open port 22 on my admin computer for any reason, and if so how?

3. Assuming that I did have access to the router/firewall at work, would I have to do anything in addition to the hint (this is pretty much the same as Q2 I suppose)?

4. Currently when I try to connect from work, my wife is at the iMac and clicks the terminal script. It sits there for about 10/20 seconds then times out. Is it waiting for a connection? Is there somewhere where I can increase the time-out period?

You can probably tell that I am not very knowledgeable in this area, so any help would be greatly appreciated.

Open and redirect ports...

For your mum to open the tunnel, she starts the terminal script. This will make her side easy, since she initiates the tunnel, so she doesn't have to open any ports for the outside world. But... you will be contacted by her tunnel, so your side needs a couple of things:
- your router has to know to which local address it should forward an incoming port 22 request, and not block it
- your machine (PC, laptop, notebook) needs to not block incoming connections on port 22
- you need to have a ssh deamon (ssh server) running on your laptop, but you probably have that.

When opening port 22 and forwarding port 22 you can sometimes tell the router to only allow this for a certain range of external ip addresses (depending on router type) .This could be your mom's ip, restricting port 22 forwarding in a way to let only your mom through.

I just set this up today, and gave my mom a Mac. It works like a charm, if port forwarding is setup correctly.
