Cisco FirePOWER User Agent – Use With the FirePOWER Management Console
KB ID 0001179 Problem FirePOWER Management Center, will give you a wealth of information on traffic/threats etc. Usually it will tell you what IP the offenders are on, but if you want to know what a USER is doing, then that means you have to look though logs see who had what IP, at what time etc. So you can install the FirePOWER User Agent on a machine, (this can be a client machine, though I usually put it on a member server). You...

Using LDP to Find an Objects ‘Distinguished Name’ in Active Directory
KB ID 0001337 Problem There are a few occasions when you need to know an objects ‘Distinguished Name’ (DN). For me it’s usually when I’ve got a device that needs to do LDAP/LDAPS lookups, (RSA Appliance, Netscaler, Cisco FirePOWER, etc).

Windows – Unable to Move an OU
KB ID 0001336 Problem I was doing some AD redesign work for a client this week, and I needed to move an Organisational Unit (OU). However the domain had other ideas; Active Directory Domain Services Windows cannot move object {OU-Name} because: Access is denied. It wasn’t a rights issue, (I was an Enterprise Administrator). Solution As it turns out, it was the same problem I’d had back when Server 2008 first came out...

Setup RANCID and ViewVC (Part One)
KB ID 0001331 Problem There are couple of good posts out there on setting up Rancid (Really Awesome New Cisco Config Differ). Some even show you how to set it up with ViewVC (Formally ViewVCS, basically a nice web based GUI front end, that does version control and highlights differences). It does this using a system called CVS (Concurrent Version System, hence the original name.) Then I had to do some more searching to get it to back...
