Deploying and Configuring The vCenter Server Appliance

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).

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).
