Ruckus ZF 7982 AP disassembly

I came across this Ruckus AP that had been knocked off it's mount by a fork lift driver and had crashed to the cement beneath it. It still worked, amazingly enough, if that tells you anything about their build quality. But I wanted to know what was inside! Mainly, I wanted to know what wireless chips they used. So here they are, the disassembly pictures!

Basic WAN VRF Routing Configuration on Cisco ISR

In this basic VRF configuration tutorial, we will look at how to set up a VRF for a WAN interface, and get routing from the Internet to the router, or from the default Global VRF out out to the internet and back into the Global VRF. There are a number of reasons you might do this, but I generally configure this to make traffic destined to the router from the Internet be routed independently instead of having the reply traffic be routed according to the routing table in the Global VRF.

Use PRTG to Monitor Session Quantities on a Server 2012 RDS Deployment

I'm kicking off the PRTG tutorials with a basic script to pull the number of RDS sessions into a sensor. This script will be able to pull in the total number of logons, and give quantities of RemoteApp sessions. You can also add specific software that you want to track the number of instances in use. Use this script to pull the aggregate quantity of sessions from a comma seperated list of session hosts, or just a single session host.


Managing Office 365 Tenants via PowerShell; Connect-O365

When you work at a Managed Services Provider that handles a large number of customers in Office 365, it's an envitability that you will spend a decent amount of time working within PowerShell. This means that you'll be constantly connecting and disconnecting PSSessions between customers. Wouldn't it be great if there were a better way? This is where I started.

Configuring Cisco Zone Based Firewall to Inspect Passive FTP Traffic

If you host an FTP server, you probably want to set it up as a passive FTP. To facilitate this with your firewall, you can do one of two things.

  1. NAT the standard FTP ports and a range of dynamic ports, and allow traffic on all those ports through the firewall.
  2. NAT TCP port 21, and do layer 7 inspection of the FTP traffic to dynamically open/forward the ports needed.

This is a walk-through for configuring option number 2. We will be connecting FTP server to external IP using port 21 as the ftp port. This assumes you already have your ZBF configured, and the zone-pair for your WAN to your Intranet is WANS_INTRA_PMAP.

Exchange Content Filtering

Content filtering built in to Exchange is kinda like free antivirus software. Big promises, but it never works like it says. It either blocks ham (good emails, opposite of spam) or not much of the spam. I use a third party content filtering service called GFI. I'm sure there are others out there, but I have little to no experience with them. If you do use a third party filtering service, you're going to want to disable the filtering built into Exchange, and here's how.
