I was listening to the Packet Pushers Show 349 'Future of Networking with Mark Townsley'  today, and they talked an awful lot about IPv6. My opinion on IPv6 in the enterprise up to now has been that it is really just a useless way to complicate LAN networking, and not ready for widespread enterprise use on the WAN. It still isn't 100% supported everywhere, no one in enterprise knows it, you almost certainly need to run dual stack or have NAT gateways, and it doesn't solve any of the problems I run into every day. Now, I think most of... + continue reading

We discovered a problem while creating a new user in our on-prem Exchange 2013 ECP.  I amused myself in resolving the issue and have decided to inflict it upon the world. On trying to create a user, the following error appeared. I had recently been working with the related databases, so this piqued my curiosity.  While I searched for answers, a co-worker discovered that you could manually select a database from the "More options" text, just below the *User logon name" field.  This did indeed work for bypassing the problem.  I didn't want to... + continue reading
Server 2016 as a Workstation
Thursday, March 30, 2017 - 09:36
My workstation came with the abhorred beloved Windows 10, beset with ads from the Windows store, invasive data mining software (in my opinion) known as Cortana, and annoying pop-ups questioning if you REALLY want to use a browser other than Edge as the default. I have to be honest, Windows 10 seemed great when it first released, but with every update, it seemed to get more and more controlling, invasive, and resource hungry. I really don't see Windows 10 as a business/workstation OS. Even the Professional version has Windows Store Ads for Candy Crush and junk like that. When I, being a... + continue reading

One thing I love about where I work, is that we like to try out new products. (...and I should really start reveiwing more) One of the products we just got in, is the Unifi Switch 24. I haven't had a chance to play with any of the software like the web GUI or CLI on this yet, but as for the hardware, the build quality is amazing! So natually, I decided to take off the cover and see what it's made of. Also, one thing that stood out to me are the send and receive LEDs on the console port, that's something very useful that I've never seen on any other console port... EVER. So... + continue reading

I recently needed to tie an old Cisco Small Business router from a partner company into our VPN topology. Unfortunately, I didn't have access to the router on the other side and it only supported legacy IKEv1 (isakmp) crypto map style VPN tunnels. After a little research, I found a great blog post from Nicolas Meesen which details how to do this in most situations, and is definitely worth a read. Unfortunately, my scenario with the FVRF being an internet vrf, and the IVRF being the global VRF will not work with just his configuration. I was actually able... + continue reading

FreePBX has been my go-to distro for CentOS/Asterisk for a long time now, and I've had huge success with past deployments. So when I first discovered that Sangoma is selling the hardware to go along with the software, I couldn't wait to get my hands on a piece, so I convinced my company to buy one to try out. Before my company bought one of these (Sangoma FreePBX Phone System 300), we looked all over online to try to find pictures of the actual hardware. Now that we got it in, we're a little dissappointed. The sales guy, who shall remain unnamed, claimed this had redundant PSUs.... + continue reading

Hello All, I ran into an issue with CPU utilization in our Hyper-V guest VMs over the last few weeks. Every few days, one of our guest VMs would suddenly go to 100% cpu and stay there, occasionally even across reboots. What was really strange, was that the Guest OS didn't report any processes taking up the CPU usage. No matter what I killed, the CPU stayed at 100%.  I started to gather information to define the scope of the issue. This was occurring on both Windows VMs and Ubuntu 14.04 VMs, and happened on more than one of our Hyper-V nodes, though it ... + continue reading

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!
