There's nothing to it really. If there are no other network connections up (ignoring lo0) then doing this on one machine: # ifconfig re0 up a.b.c.1/24 and this on another: # ifconfig re0 up a.b.c.2/24 Will, if they are on the same ethernet segment (as, for example, when they're both connected to the same switch or directly with a crossover cable*), and considering any firewalls present en route, allow them to communicate with one another on the configured address. Of course each re0 should be changed to the appropriate device name on the machine, and a, b and c must be chosen so as not to conflict with any other address that may be present on existing network devices (or networks they route to, such as the internet). Matthew [*] Or, if you have a machine made after the stone age with autosensing ethernet hardware, any cable.
