How to get two ethernet cables into a mac

[Hakimm]

Basically i need to have internet supplied through one cable and another being connected to another macbook. Wifi is not an option.

Ive seen adaptors which literal have two ethernet ports on one side and one o the other but these are only in the us and i need it for 9 days times and also not sure if they will work. Thanks!

I'd use an external switch; we used to have them in offices. Basically they take an input ethernet cable and share it with other ethernet cables.

Router and wired network?

A Firewire cable between the MacBooks (Pro only) or a small switch / hub on the Ethernet as would be the normal way to share a connection.
