What NetFlow Analyzer can do for you? Monitors network bandwidth and traffic
patterns at an interface-level. Reveals which users, apps, and protocols are
consuming the most bandwidth. Provides multi-vendor support for NetFlow,
J-Flow, sFlow and other flows. Make informed decisions using capacity
planning reports.

I just said:
"My cable issues don't yet have to do with connectors. From posts I have
read here I was under the impression that 1wire would work over Cat5 up to
100m. Not for me. I am testing with one sensor, a waterproof DS18B20 from
Adafruit. Longest cable that works is about 45 feet. I have tried a LinkUSB
and a HobbyBoards powered master. Using a Raspberry Pi."
Correction:
I just tested with a 100 feet of different Cat5E and it works.
The cable that doesn't work is off a 200 foot length of outdoor Cat5 bought
online. What is the chance that this latter cable is faulty. It tests good
with a able tester, but that is just continuity. What other factors are
there?
How can I buy cable and know it's good stuff and not junk?? (I need 170
feet.)
I'm on a remote island in B.C. Canada. Cannot go to the corner store and
buy more cable.
Thanks,
Peter
