How to transfer big files between two Macs using a firewire cable
If you have two Macs and a firewire cable, you can make a superfast TCP/IP connection over which you can ftp or ssh or whatever. Here is a step-by-step way to do it, mostly for my own benefit, so I don't have to think too much.
Pretend you have two Macs. In my case, I have a G5 and a Powerbook.
1. Connect one end of the firewire cable to the G5; connect the other end to the Powerbook.
2. On each computer, open the System Preferences->Network panel.
3. Switch each panel to Show: Built-in Firewire.
4. On the G5, use these settings. You can pick and IP subnet you want, but I used 10.43.0.0/24 for no particular reason, other than it is different than my LAN:
5. On the Powerbook, use these settings. The only difference is that the IP address is different:
Now go to either computer and open a file share, or ssh, or ftp, or whatever. Use the IP address of the other machine. For example, on the powerbook:
% scp bigfile.tar 10.43.0.1:
Finder -> Go -> Connect to Server and use afp://10.43.0.1/ (assuming you have Apple File Sharing enabled).
Hints and possible problems:
1. Make sure your Firewall is OFF on both machines, or you at least set the right ports open.
2. Make sure Built-in Firewire is enabled on the Network Port Configurations screen on the Network Panel.
