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.

have a chrimper
and some ends for it?
*netdiva : *I would send an email to the list in a new thread asking
if anyone will be around. I'll be around this evening (around 6pm and
on) and I have keys . But if anyone else will be there they can let
you in via the intercom.
Thanks,
Andrew

sorry for YELLING, but this is critical to sudo room's
continued operation.
I will be around Monday and Tuesday evening to hack on
door access mainly to
install the keypad and get the raspi in a more stable
state, even if that
means having it restart every 20 minutes.
I just spent some time updating all the software, fixing some
networking issues, and disabling services on the raspi in
question. It
had a full X server + desktop environment booting by default, even
with no display attached! So I disabled all that and now the
memory
usage is much lower. I suspect the "OOM killer" was causing these
problems, which fits our experience of features/services
dropping one
by one until nothing worked at all - first captive DNS would
go away,
then web server would go away, then dhcpd would go away...
It works now. Maybe this time it will work a few hours later. :)
