Factory Reset Firepower 4100 & 9300

I got my hands on some Cisco Firepower 4100 units and after playing around with them I wanted to reset them to factory settings, essentially erase the “startup-config” on the FXOS. The Firepower units act a little differently than your normal Cisco IOS or ASA and you can’t just erase startup-config and reload the device, that would be too easy. I was able to find that if you do a password recovery on the unit it erases the configuration  and that’s as close as I got for a factory reset. Continue reading

RBAC Radius with Microsoft NPS 2012 R2

safe-access-controlIn this configuration I’m at looking at using Microsoft NPS 2012 R2 as radius server and I’m going to skip the installation of NPS because it really is just a next, next, finish installation. In this demo I already have this NPS system connected to a Windows domain, my goal is to create role based access on Cisco IOS routers while using radius to login. I’ll have a couple for active directory accounts each them will represent different types of allowed access to these IOS routers. One account will get full administrative access while the other will only get read access, how cool cat is that 😉 !

PRTG Daily Email Powershell Script

PRTG-LogoSo I don’t write much powershell but recently I needed a way to send daily emails out of PRTG. Thanks Paessler which has kept it simple with their PRTG monitoring system as the hardest part of this script was getting the data in HTML. (Remember I don’t write much powershell. 😉 ) If you have not used PRTG before check it out if you need some alerting in your environment. Personally this is one of my favorite systems for just monitoring because a lot of other monitoring systems include everything but the kitchen sink and reality we just need to know what’s up and what’s down.

Install Rancid and ViewVC on Centos 7

In this post I want to walk though the steps to install Rancid on CentOS 7 minimal. Rancid is a great tool to help monitor a device configuration for any changes. It also keeps track of them by using CVS (Concurrent Version System) for backups, so you can go back and compare versions or revert to a previous configuration. Rancid supports multiple hardware from Cisco, HP, Dell, Juniper and more. This is all open-source so you can create custom scripts or add commands to really make this a personal repository that fits your company.  During this install guide several things are required when we install Rancid, I have tired to make this as simple as possible but its not just a type and watch it install. You have to customize some of the scripts to make Rancid work like it should. Read it though and follow along.
