Networking 2 Macs

I have a friend who has a Macbook Pro running OS X (snow leopard). She just acquired a G5 set up as a disk farm (running Leopard).

I figured that simply attaching an ethernet cable between the 2 machines would be enough to give her access to the drives on the disk farm from her laptop.

But that didn't work. The network setup process kept asking for a router address - which I took to mean that I needed to add a router to get a network established.

We didn't have a spare router so I gave up and said I would "ask around" for options.

So I'm asking. Can I establish a connection between the 2 machines with just an ethernet cable?

You should be able to, you might need to find a crossed Ethernet cable (you shouldn't, both the macbook and G5 should be auto sensing)

You could try manually setting the macbook and g5 with a static ip in the same range and the same subnet mask

I tried the static address route. But regardless of the setting (Manual, DHCP, etc.) the computers insisted on a router address. I put a bogus address in to satisfy the dialog but then the computers just said "No connection".

use static adress and as a router use the ip of the other mac.
example g5 <--- this would be the router on the macbook/pro or whatever

devils_advisor is correct. This is how I network extra PC's and devices in my room. It seems to work for everything. I also disable ipv6 (or set to link-local only) on OSX.

Under Winblows, I set up an account with identical name and password to first machine, on second machine. Then there are no permission errors when navigating/copying. This may also be the case on Macs, but I doubt it.

PS. I have a direct cable connection, and I assume it is a crossover cable. You can also use the other private IP ranges 192.168.0.x, 192.168.1.x, 10.0.0.x

Best of luck!

You can also use the wireless "create computer to computer network" option. This turns the hosting computer into a local router for the purpose of connecting the two machines). Just go under the airport icon and create a network.

This is what I do when I'm at a location with no wireless and I want to play a networked game with my kids.
