Re-Image and Update the Cisco FirePOWER Services Module

KB ID 0001164 Problem This takes ages! Seriously, if it’s late in the afternoon you might want to do this tomorrow morning, or leave the re-imaging running overnight. (Remember if you set the FirePOWER module to ‘fail-closed’, you will lose internet access, so you might want to change that to ‘fail-open’ as well). The process is a LOT EASIER to do in the ASDM, I’m not usually an advocate of the GUI,...

Windows Server – Locate CA / Certificate Services

KB ID 0001163 Problem A colleague was having some certificate problems onsite the other week. Someone suggested just using Certificate Services to simplify matters. I said I’d spin it up and configure it for him, (I’ve done a lot of Microsoft CA work, search the site!)

I knew the client had some Catalist 3750’s So I suggested going and creating an Ether Channel to the two NICs in the NAS box, to try and cure the problem. However when I went onsite, I noticed the 3750 didn’t have any spare Gigabit ports...

Audi A6 – Luggage Compartment Fuse Box Location

KB ID 0001161 Problem I know it’s not the usual site content, but PNL was born from my dislike of vendor documentation, and crappy documentation is not limited to the world of IT. The 12v power socket in my A6 wasn’t working, this was probably because there was a 1p coin stuck in it that took a lot of fishing out, I assumed the fuse had blown, and put up with it for a while. When I finally got round to sorting it out...
