Hej sluggere,

Jeg skal til at kigge på ADSL til Linux, og mangler et krydset kabel.
Nedenfor er en beskrivelse af kablet. Hvis der er én af jer der kan
lave et sådan kabel her søndag eftermiddag så ring venligst til mig
på 20401272.

Running two ATM NICs back-to-back
---------------------------------

It is also possible to run with two ATM NICs connected back-to-
back, and no
switch in between*. This is great for simple test environments.

First, if you're using UTP or STP-5, you need a suitable cable. Our
experience with standard 100Base-T back-to-back cables was not
good. It
appears that the pin-out they use is different. After some false
starts, we
found that the following cable works:

RJ45                            RJ45
   1        ------------        7
   2        ------------        8

   7        ------------        1
   8        ------------        2

Pins 3, 4, 5, 6 unconnected.

You can also make up a loopback cable with 1 - 7 and 2 - 8
connected for
ultra-cheap setups.
