Pokethernet – The swiss army knife of cable testers

Thanks to Mike Hammett for Sharing this with me.

For anyone dealing with lots of ethernet connections, be that PoE runs up towers or 48 port switches providing to office desks, hotel rooms etc, we’ve all had to test and troubleshoot connection issues.

These can range from physical connectivity problems like:
– Cable run too long
– Pair shorts
– PoE voltage drop
– Broken wires/cable

Then there’s the connectivity tests after you fix and test the wiring:
– Does auto-negotiate work?
– Do you get DHCP or can you see other IP’s on the network?
– Does the port show any CRC errors?

Which in total normally require a whole bunch of tools to run through (or a super expensive fluke network tester) to test wire pairs, use TDR devices to determine if a wire is broken and if so how far along, then test physical port connectivity and errors.

So in come the guys from Pockethernet, with the following solution:

(youtube link here if embed doesn’t work.)

They’ve combined all of the features listed above and made it simple to use by connecting it via Bluetooth to your smartphone. Then on top of that they’ve made it incredibly cheap in comparison to the alternatives.

At present they are shipping to the US and EU only, but using a service like shipito you can have it forwarded anywhere in the world, and as they’ve already reached the minimum contribution amount it’s safe to say this project will be going ahead.

I’m really glad to see a useful project like this take off, it is an excellent innovation and is going to be a very useful gadget for network techs to have in their tool bags.

Replacing Hotspot SSL certificates with a script

While needing to update a bunch of routers with new SSL certificates for the hotspot config the other day, I realised there is currently no way to import a certificate in RouterOS via a scripted function (at least not that I’ve discovered prior to v6.3).

As such I set out to find a way to update routers with a single copy/paste block of code that would work across all versions and could also be run using a system such as router-tools or via an API interface and came up with the following.

TheBrothersWISP 16 – Ham Radio, WISP Business Ideas, SDRs

We had the whole crew! JJ, Justin, Andrew, myself(Greg), and a special guest Bryon Jeffers from Missouri. Bryon did radio work for years, and now owns and operates a WISP. He is also heavy into Ham(I prefer bacon).

Some of the things discussed:
School E-Rate Program
JJ’s Software Defined Radio (SDR)
Codec2
FDMDV
FreeDV
BGP Community Strings
Mikrotik RB260GS switch – SFP port on back
My homemade fiber tester.
Unifi API 1, 2, and 3.
Callmanager express, 6 analog ports, elastix VM on the cheap.
Upcoming Mikrotik MUM
Upcoming WISPAPALOOZA

TheBrothersWISP 15 – New UBNT, Tools, Catching Up

It has been ages since we have casted, so it was obvious that we had a lot to say…over 2 hours worth of stuff to say. We covered a lot of ground, so hang on to your britches. This episode we had Andrew Cox, Justin Wilson, Mike Hammett, and myself Greg Sowell.

Cool console: Terminal health

The following is a short but useful script which allows your system note to output recent info regarding router health and/or other details you might be interested in.
