Connect two macs thru gigabit

[TyleRomeo]

I have two macs. A power mac g4 and a power mac g5. The G4 has an airport and it's how I connect to the internet. I have connected the two macs with an ethernet cable hoping that my g5 power mac can also have internet via the airport, without plugging it into the router or installing an airport extreme card in that power mac g5.

It's very easy. On the G4, enable internet sharing in the "Sharing" pane of System Preferences. It's under the internet tab. Just turn internet sharing on, and click the check box that allows you to share your connection from Airport to computers using ethernet. the G4 will assign the G5 an ip address over ethernet.

It's very simple and self explanatory once you get the dialogue box up.

Indeed, that's exactly how you do it.

I'm sharing my Mac Pro's hard-wired Ethernet connection with my MacBook over Airport. Works like a charm.

Thanks guys, I tried that and the reason it wasn't working was becuase i had a firewall up on my mac with the airport card, when I got rid of it, it started to work.

does that give you 1000MB/s transfer speed? or still the 100MB/s?

also how are the IPs dealt with?

will that also work with a PC hooking into my macpro?

The G5 will have a downstream IP address. And transfers between the two powermacs might be at gigabit speeds, but activity on the internet certainly will not be -- it will be choked by the speed of Airport (11MBPS if Airport and 54 if its AE), even if your internet connection is faster.

And yes, you can hook any computer into the "sharing" computer's ethernet port -- it doesn't matter if it's Windows or Mac or whatever.

I have a MacPro + G4 Gigabit networked...transfer rate is 39MB/s. Remember that MB/s is different to Gigabit unit which is 1000mbps (megabits per second or theoretical max of ~120MB/s).

I read that in practice one can only expect to reach 70% of network capacity due to overheads, I seem to be well short of that but I'm using cheap CAT5 cable, maybe CAT6 needed.
