[wellylug] Dummy ethernet crossover?

[Edmund A. Hintz]

Hi all...

    I've got a bit of an oddball problem here... I need to fool an
ethernet interface into thinking it's up (it's a long story, just trust
me that I need to do this). I tried doing a crossover cable of sorts by
snipping a cat5 cable, stripping the plastic, and twisting together 1-3
and 2-6. Doesn't work. I'm guessing I need some sort of capacitor or
something in the loop, but all I can find on google is xover cables
(great, but there's only 1 enet interface in the loop so it's useless).
Anybody know where I need to look to find a solution?

    As things stand now, I can plug the machine into a switch, with
nothing else plugged into said switch, and it does what I need it to do
(virtual machines talking to each other). But I'd like to find a more
portable solution than lugging about a switch; it seems like a properly
wired up RJ45 jack should do the trick...
