Mac Address Formatter

I decided to try my hand at “vibe” coding and and create an app that solves an irritating problem for me.

It’s called “mac-formatter” and takes a MAC address in any format and coverts to the 3 main formats I work with daily (IEEE, RADIUS, and Cisco)

It’is a python app and you can install from PyPi at https://pypi.org/project/mac-formatter-gui/

The commands are:

pip install mac-formatter-gui
mac-formatter

The source can be found at https://github.com/njohnsn-networking/mac_formatter

I hope you find it useful! If you find any problems, open an issue at GitHub!

Antenna Repaired!

In August of 2024, My son snagged a guy rope with the lawn tractor and this happened:

The most important thing was he was not hurt.

I order a replacement antenna that fall and today my son helped me get it back up in the air!

I still need to make some adjustments to the SWR on 40 and 80 meters, but I’m finally back on the HF bands!

Connecting Aruba Controllers to Central on Premises (COP)

After a few frustrating weeks working with the Aruba Technical Assistance Center (TAC). I have our Aruba wireless controllers working with our Central on Premises (COP) cluster.

Aruba’s documentation consisted of a brief and incorrect work document and the instructions in the COP documentation are not clear on what exactly needs done.

So I’ve written up the instructions in a PDF document to try and save others from the same pain. See below.
