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.

IPv6 over PPPoE – RouterOS v5.10

IPv6 prefix delegation support comes to PPPoE in RouterOS version v5.10* so for those of you ready to jump onboard this release, here’s my attempt at a best-practice way to set it all up.

IPv6 has been around in RouterOS for a while now, but the specific feature that was introduced is called “DHCPv6 Prefix Delegation” which allows RouterOS to receive a prefix (or a bunch of framed routes if you’re more familiar with that terminology) that it can then distribute out itself.

This means for someone like myself, using IPv6 with my local Internet Service Provider becomes relatively straightforward, with no more need for tunneled IPv6 connections. Continue reading IPv6 over PPPoE – RouterOS v5.10

Bridging ESX Virtual Switch Networks using MikroTik and EoIP/Vlan/VPLS

This is a bit of a different post based on some configuration I did just recently to enable the bridging of a Virtual Switch between 2 ESX hosts.

There is an VMWare option for this called a “VMware vSphere Distributed Switch” however this requires one of the higher end licencing packages so isn’t available on the free or basic packages, but there are many different uses you might have for this,  from simply creating a temporary bridge while you migrate servers to a remote host, or in my case, creating a bridge network across 2 hosts that use a RouterOS vm as the gateway/firewall for the servers.
