Someone asked about the "null modem" twisted pair cable for a direct (say)
ThinkPad-UnixBox connection. I misplaced the sender's address so I'll
post here. This is from the FAQ on ethernet.
03.11Q: Can I connect the 10BaseT interface of two devices directly
together, without using a hub?
A: Yes, but not more than 2 devices, and you also need a special
jumper cable between the two 10BaseT ports:
RJ45 pin RJ45 pin
======== ========
1 <--[TX+]--------[RX+]--> 3
2 <--[TX-]--------[RX-]--> 6
3 <--[RX+]--------[TX+]--> 1
6 <--[RX-]--------[TX-]--> 2
One of our technicians put it together for me it about three minutes
and it works very well.
Another thing, if you are connecting to a Sun, be sure to not disable
the link-test (on the Sun). Yes, it's a silly thing to do, but I did
it a long time ago because I didn't want to keep seeing some even sillier
start-up messages at boot time. And I never dreamt I'd want an ethernet
at on my "standalone" workstation.
Cheers,
