A six-pack?! *Good* beer?!

These British network techs must be pretty expensive! :)

Not a problem.

Your Honor, I'd like to amend my reply to read: "Properly switch the wires on either 
one end or the other to make the crossover."  :)

me gots a powerbook520 and it is so fustrating! there are no flippin

ps: have looked at debian port for mac but the only hardware that isnt
supported is the nic, so there wouldnt be much point in trying that.

There's something called an ethernet crossover cable, you 
 

can hookup two
   

machines back to back with this and not need a hub.
 

on the subject of crossover cables, do you know where you can get
adapters that go on the end of normal patch cables to convert them
to crossover? 

The reason i ask is because i only want to carry one network cable in
laptop bag but would be useful to have a crossover cable sometimes..
thanks

It's somewhat pointless to have an adapter I would think since you are still
going to need the male RJ-45 end on both ends.  If you going to carry and
adapter and a cable isn't just as easy to carry two cables?  If you really
want to do it, one easy way would be to butcher an existing patch cable and
cut off one end and get one of the wall jack inserts for cat-5 and punch it
down as a crossover.

Hey, that gives me an idea. How about a cable with two heads on one end, 
one being a crossover? Or would that introduce noise?

On a side note, newer Macintoshes will autosense the need to internally 
create a crossover connection on their ethernet ports, and will 
autonegotiate which end does it when you connect two Macs. Really cool!

This sounds like a do-it-yourself job. Take about six inches of cat-5, put a regular connector on one end and a female connector on the other. Switch the wires on either one end or the other to make it crossover.
   

yeah, need to smile at someone who has crimpers :-)

Or a "biscuit" with two RJ-45 jacks. About 5 dollars and 15 minutes 
worth of work (ten of which is finding the wiring diagram on the net).

Aside from the fact that, as another respondent pointed out, you'll
still need another cable to plug in to the other side of the adapter,
and so you're probably ahead to just have two cables, google is your
friend:

Careful with this if you try it yourself because it is not a 1 to 1
crossover.  Ethernet only uses ping 2,3,4, and 6 so you need to cross 2 to
4, 3 to 6, 4 to 2, and 6 to 3.

male end of   Cross-over adapter  
Rj-45 straightthat clips on the
through cable end of rj-45 cable.

im sure i have seen one of these somewhere, just cant remember where!

your idea of making one isnt bad but if the 'adapter' is gonna be a
cable, as you say; i might as well just carry two cables.

If you can't do it maybe you know a networking person who can.

If there are any network techs in your local LUG, one could make a 
patch cable for you for the cost of parts plus a 6-pack of good beer.
