Ok, I learned something new. :) I've had "get another fxp0 and a real switch" for the home network on my list for a while now, I guess it's time to move that up a little. > Crossover cables work fine, usually, but I personally *never* use them. > I always throw a switch in between the machines and let it negotiate > the duplex mode with each machine independantly, plus it gives me nice > shiny LEDs that tell me what the switch thinks the port is doing as > a sanity check. Yeah, I miss the blinky lights. I went to the x-over cable because the hub I bought originally was giving me non-stop collisions under load. It worked really well for about 5 months, then the last couple months it's given me problems. I'm still learning the whole networking thing, so I appreciate the insight.
