[sudo-discuss] DOOR ACCESS HACKING!

[Anon195714]

Hi Andrew-

Yes I have a crimper & ends, but standard practice is to put a jack on
each end of a cable (rather than a plug) and then use a patch cord
(which can be as short as 6" or as long as needed) to the device at each
end.

Crimping plugs onto twisted pair cable isn't recommended because twisted
pair solid conductor wire should be fastened permanently in place and
not subjected to flexing etc., otherwise the cable can downgrade or the
plugs can go faulty.  If the door device has an Ethernet jack on it and
will be permanently mounted, then it's safe to crimp a plug onto that
end of the wire. 

I'm sure I have some Cat5 jacks around, I'll look. 

At some point we can discuss doing the whole patch panel thing upstairs. 

Meanwhile tonight I have some diagrams to produce for a client... more
stuff about door stuff!  For some weird reason I've gotten stuck in a
"door stuff" groove recently.  It must be the squirrels.  The answer to
many puzzling coincidences is "squirrels."

TTYs-

-G.
