Part of the problem may be that I am using a home-made crossover cable - from a standard A-B cable. I found some instructions for doing this in a HOW-TO where pins 1A is switched to 3B, 2A to 6B and the return similar.
Yes, that is correct.
However the colour codes on my wire did not match the How-to description, and I'm not sure which is 1 and which is pin8.
If you look at the end of a piece of cable, as if it is a rattle snake which is going to bite you on the nose and has it's tail in the air (i.e you are looking at the end of the RJ45 plug which plugs into a socket and the clip is uppermost), or if you imagine standing on it's tail so it's jaw drops as it slithers away from you (i.e you are looking at the plug from the cable end with the clip downwards), then the pins are numbered from 1 to 8 from left to right.
On my crossover cables:
T568A: 1=White with Green stripe 2=Green with White stripe 3=White with Orange stripe 4=Blue with White stripe 5=White with Blue stripe 6=Orange with White stripe 7=White with Brown stripe 8=Brown with White stripe
T568B: 1=White with Orange stripe 2=Orange with White stripe 3=White with Green stripe 4=Blue with White stripe 5=White with Blue stripe 6=Green with White stripe 7=White with Brown stripe 8=Brown with White stripe
Hope that helps.
