I know this is out of topic, but.. what would you guys recommend for remote desktop from mac to mac? I have a desktop in florida I'd like to access from colorado (where I'm living now currently).
I have used the ichat screen share, but you have to request permission so if no one is on the other end to accept your not connecting.
Also, I have the Apple Remote Desktop (10 clients) but I never got the software working correctly.
I don't think your situation with RDC is going to be any different if you use vnc. I suggest since you said you have 2 PCs that you ensure that you can connect PC to PC using RDC, my guess is that you can't do that at the moment either.
Depending on exactly what you want to do with the Florida to Colorado thing you have a few options.
1) Actually control the remote Mac (view the screen, interact with the OS GUI):
Enable ssh(Remote Login) on the Colorado Machine.
Ensure you have a Static IP on the Colorado Machine (inside/behind router)
Ensure you do the port forward to port 22 like you did for 3389 before (this allows the external IP to route port 22 to your Colorado Mac)
Open a Terminal
ssh into the Colorado machine doing port forwarding (You'll need a way to know your Public IP address, look up DynDNS.org. Most Linksys Routers support this. So you'd use a <uniquename>.dyndns.org or similar address)
> ssh -L 5901:localhost:5900 ColoradoMacIP
Then simply open the screen sharing app and point it to localhost:5901
Another option is HamachiX, I've been using this to connect my Mac and my Mom's Mac to help her out. However, I've had to continuously "Install System Components" inside Hamachi in order to get the underlying processes running right???? Haven't looked into this too much, as to the root cause.
2) Just get to files/directories on the Colorado Mac
Just do the same stuff for setting up ssh on the Colorado Mac, but then just use Filezilla and sftp(ftp over ssh) into the Colorado Mac.
I'd be glad to help you with this, just send me a PM.
