PlaystationVUE, Amazon FireTV, pfSense, and Traffic Limiting

PlaystationVUE, Amazon FireTV, pfSense, and Traffic Limiting

Quick Note

All of the conclusions below were based off of my individual findings dealing with Vue and my cable provider. But, I used some parts of pfSense that a lot of people talk about and I thought it would be good to put it on paper for others to find.

For all of the pfSense examples below I am using pfSense 2.4.0-BETA on an Netgate SG-1000.

The Issue

When the decision to cut the cord it was with much excitement about the upcoming experimenting with different content providers. Firs we tested hardware and ended up settling on the Amazon FireTV. Then we started a free trial of both Sling and Playstation Vue. While going back and forth between the two I started to notice an issue. Sling was streaming without issue while we kept getting queued up with Vue.

I began to investigate. At the time I was running the system wireless through a Ubquiti UniFi setup, through our pfSense firewall, and out of our cable connection (70 down, 4 up). I noticed that while streaming Slack the data flow looked steady. But, when Vue was streaming, there were constant spikes in upload and download utilization. This really got me thinking…why would we be seeing spikes in both directions with a streaming service?

I started investigating. After digging and digging I finally found a post (which I can no longer find the link to…) that shed some light onto the subject. It was a description of the mechanism used by the Vue app to proactively monitor the bandwidth available to stream. It basically said that the due app was running a small bandwidth test periodically to test the available bandwidth for streaming.

This got me thinking about my cable internet provider. I had often run into issues with my link quality becoming garbage anytime I hit the limit on 70 down & 4 up on our account. The policing the company used was vicious and would drop packets like mad.

Reset Toner Counter on brother HL-3170CDW

Quick Note:

I thought I would make a quick post about how I reset the toner counters on my brother HL-3170CDW.  I find myself having to search for these steps every few months.

The Request:

I love my brother HL-3170CDW printer (CLICK HERE).  It performs great and always works for us.  The one thing I do not like is buying toner cartridges…and I have yet to do so!  I have owned this printer since August 13, 2013 and have yet to replace the toner even though I use it regularly.  My current page count is a total 1,432 pages with 1,009 being color and 423 being monochrome and I am still using the starter cartridges that came with the printer.  The brother spec sheet (CLICK HERE) states that the starter cartridges are good for 1,000 pages each, but I have been given the “Toner Low” error almost 3 times now.

Cisco DMVPN Phase 3

The Request:

I have a client with a data center, a headquarters/DR site, and a lot of branches spread out all over the world with Internet connectivity.

They are currently using static IPSEC Internet facing VPNs to connect to their data center and HQ environemts, but the company is hitting a growth spurt and they are quickly realizing this solution is becoming difficult to scale and manage with their limited in-house IT staff.

The client wanted to stick with Internet based VPNs for connectivity. They also wanted a solution that would allow them to easily stand up a new remote site quickly with a template configuration and provide tunnel redundancy between the data center and HQ locations. They also wanted direct site-to-site communications when necessary.

Cisco 6807 VSS ISSU Upgrade

The Request:

I have a client with multiple 6807 VSS pairs that required an IOS upgrade. All of the pairs have a single SUP2-T in each chassis and were in the 15 code train.

Although the ISSU process is very straight forward I wanted to put this quick process up as I had to search through multiple documents to gather all the pieces I needed to knock it out.

GoDaddy: Delegate Subdomain to Different Nameserver

  1. Access your GoDaddy domain manager
  2. Select your domain
  3. Select the “DNS Zone File” Tab
  4. Select “Add Record”
  5. Create a new “Nameserver” entry. See capture below. The “host” will be the subdomain you want to point to the new server. Use the proper nameserver naming format or GoDaddy will kick an error.5
  6. If you do not have a FQDN for your nameserver you will want to create an A record pointing to its IP:6

THANKS!

I would like to that Glen Kemp who began discussing this topic with me. I thought I should put this up even though GoDaddy clearly supports this procedure in their Support Forums.

Convert Audio Files for use with the Cisco Unified Communications Suite

Quick Note:

I thought I would make a quick post around how I prepare audio files for deployment in Unity Connection, Communications Manager, Contact Center Express, and other Cisco UC[1] products. This post will be focused around Unity Connections but the same method can be used for all applications.

The Request:

Due to inclement weather conditions in the southeast I had multiple clients that needed emergency messages uploaded to their Unity Connection auto attendants. I have some clients that have call handler managers and record and configure their own messages on the systems.  But, I have quite a few that would much rather just record a message with whatever is handy (an iPhone more and more these days) and e-mail it to me for uploading and configuration.
