10.5: A number of ways to access Screen Sharing
Authored by: hermes369 on Oct 28, '07 06:32:48PM

I need a way to assign display numbers to several Macs on one network. I'm using Vine Server on each one now. I'm wondering where I need to go to specify a unique number on each Mac; that is, if I'm going to use the baked-in Leopard VNC. Any thoughts?

10.5: A number of ways to access Screen Sharing

Assuming that you're referring to accessing multiple machines behind the same router, I would do it at the router. The default port for VNC is 5900, and this is display 0. Display 1 is port 5901, and so on. You can use your router's port forwarding feature to map its external port 5900 to port 5900 of machine 1, external port 5901 to port 5900 of machine 2, and etc.

I haven't noticed an option for display numbers in the screen sharing client (it will, however, work seamlessly with them if it sees them advertised over bonjour), but you can just append the port numbers for this too. For instance, if your router's external address was 123.45.67.89, you could access computer 1 using vnc://123.45.67.89 (port 5900 is assumed), computer 2 using vnc://123.45.67.89:5901, computer 3 using vnc://123.45.67.89:5902...

I was offered a penny for my thoughts, so I gave my two cents... I got ripped off.
