Enterprise Computing In The Home

Published by sbostedor on August 7th, 2011 - in Blog Post

2011-08-07_1043I have a subscription to Microsoft Technet.  That allows you to download and use just about any of their business applications, servers, and operating systems for learning and testing purposes for one annual cost.  For as much development, research, and geekery that I do on a daily basis, this is priceless.

I have a pretty powerful server in my basement.  It is powered by a quad core XEON with 16GB of RAM.  I decided to install Windows 2008 r2 Datacenter on it so that I can play with Hyper-V.  At work, we use almost exclusively VMWare ESX servers.  Due to their greedy tampering with their already overly taxing pricing structure, I am seriously considering switching to Microsoft’s Hyper-V solution.

My first Virtual Machine on the server was a Windows 2008 R2 domain controller.  I also added the roles of DHCP and DNS for reasons obvious to anyone who has read this far and is still with me. 

I’ve added every computer and laptop to the new BOSTEDOR.NET domain but I left them logging in as local user accounts until I either have time to migrate their settings manually to a domain user profile or find a good tool that will do it for me.

My next bit of bringing the Enterprise into the home is to play with various Internet security gateway products to see which one delivers the speed, accuracy, and security that works best for home users at an affordable cost.

Charter Business Internet has been making my day HELL!

Published by sbostedor on June 29th, 2009 - in Blog Post

Here’s the chain of events:

Here’s what happened …

  1. Lightning struck near our building, sending a surge into the building by way of the COAX broadband Internet cable
  2. The strike blew the cable modem
  3. Charter was called and they brought us a new cable modem.  The tech seemed to be unsure of how to provision it but seemed confident that he had it correct when he left. The initial tests of Internet connectivity seemed to confirm this.
  4. After the cable connection was revived, I quickly discovered that the current from the lightning strike followed the Ethernet cable out of the back of the cable modem and into the firebox firewall that provided Internet access to a critical web server and a number of other shop floor devices.  The device would appear powered on but would not route traffic.
  5. This was the backup device that was put into place because it’s predecessor had died a couple of weeks earlier.  This left us with no device to fail over to.  we were forced to put the web server back onto the TZ170 router that it was removed from in the past due to performance reasons.
  6. I configured the Sonicwall TZ170 for the NAT and performed a connectivity test.  The speed tests on the TZ170 were equal to the old firebox.  Everything looked great  … at first …
  7. Over the weekend, the TZ170 stopped routing published traffic to and from the servers.  A reboot of the router seemed to have cleared it up for a while
  8. Reports were pouring in that customers could not access the web and our remote staff could not access the remote terminal server reliably.
  9. This morning, I started to investigate these reports and believed that I had found the root cause. I thought that it was because the cable guy just forgot to provision the correct static IP addresses for our router.
  10. I called Charter again and they assured me that the correct addresses were provisioned correctly.  We rebooted the cable modem and the TZ170 and everything seemed to work for the duration of the support call.  We hung up.
  11. 15 minutes later, the servers were inaccessible from the outside again.
  12. I connected my MacBook Pro directly into the cable modem and assigned it an available static IP address from our public pool.  I got nothing.
  13. I removed the static IP from the macbook and set it to obtain via DHCP and … It was gived an address by the modem!  This was bad!  Really bad!  But really good at the same time because now I knew exactly what the problem was without a doubt!

The cable modem should NEVER be giving out automatic dynamic IP addresses because everything is statically assigned to published servers.  We only have a small range of addresses assigned to us and all but two are taken by servers and services.  The address that the modem gave to my MacBook Pro was actually the address that the TZ170 was statically assigned.

So, this whole thing was cased by an IP address conflict caused by a misconfiguration that left the DHCP server running on the modem.  The Charter guy should have known better.

I called Charter back and let them know what I found.  They logged into the router, disabled DHCP, and everything has been working since.

To add to this story, we performed a Pretty massive server room consolidation project over the weekend that went off without a hitch.  Instead of getting praise for the awesome job that we did, this Charter screwup made it look to the company like our move caused the Internet servers to go off line for 2 days off and on.

They will never understand the root cause … and this is the thankless life of an IT Admin.

The IT Accounting Debate

Published by sbostedor on February 26th, 2009 - in opinion

An unnamed company has a defunct training room with 5 new computers sitting in it with only 3 of them ever being used. In fact, two of the computers have not been plugged into the power sockets in the 4 months since they were purchased.

There are no future plans to ever utilize those two computers. The company has dismantled its training department and has no plans to reinstate it.

A new need has developed for a PC on the manufacturing line that would give valuable feedback to the workers on that line. The manager for that department suggested that, instead of purchasing a new computer, we redeploy one of those wasted training room computers to the new line.

Person A in the IT department argued that this would violate some accounting practice that he was not sure of. He said that, if this department wants a computer, they need to account for it’s dollars at a department level as if it were a new computer and not skate on the fact that it has already been purchased by the company,

He believes that moving the computer from one department to another is an Accounting issue that needs to be realized as a cost to that department.

Person B takes the view that the company realizes resources as a whole and not as bickering departments. He believes that a move of an unused resource between departments has nothing to do with Accounting.

B argues that the new computer has been sitting on the floor of the training room for months unused is actually wasting the company’s money that can be only put to value by transferring it to an area of the company where it can be used to produce goods.

Person A and Person B seem to have different paradigms of how the accounting of computer equipment should be done. Person A partakes in the old school paradigm that pits departments against neighboring departments for control and usage of resources while Person B sees the company as a whole where every resource is accounted for on a company level.

Person A insists that there is some Accounting law that needs to be adhered to when moving a computer from one area of the company to another that requires that department realize the cost of the equipment as if it were a new purchase. When asked for an example, Person A simply shrugged and said that he didn’t want to argue about that and changed the subject.

Who is right? Person A or Person B? Who would you want in your IT Department?

19 year old commits suicide on Justin.TV

Published by sbostedor on November 20th, 2008 - in news

Abraham Briggs (A.K.A. CandyJunkie) committed suicide by drug overdose live on Justin.TV yesterday. What follows is the forum post that outlines the chain of events:

- CandyJunkie creates thread telling Misc. he’ll overdose himself again on drugs live on Justin.tv
- CandyJunkie posts the amount of drugs he’s going to take
- Mods don’t take it seriously because of his past trolling
- People egg him on
- CandyJunkie posts a copied suicide note
- People keep egging him on
- He pops the pills and goes to sleep
- He breathes for a few hours, people think he’s going to be alright and keep joking and trash talking on his JTV log.
- Some time later many people realize he was not moving.
- I find his personal details through E-detectivery, I figure out his name and number and location.
- Personal details posted on Misc. I request people to call the cops because I live in India and had no way to make International calls all by myself.
- People tell me he’s a troll and nobody calls. Staberella especially is quite a huge cynic and says that he wasn’t going to die on that kind of drugs, she insists nothing is going to happen and that people should just gtfo of the thread.
- I send an email to Miami Police on their official email on their website, Email not functioning!
- I call Miami Police from my dad’s phone and speak to at least three cops and one person from the 911 line (whatever it is) for over 8 minutes about the situation, the people there do not take the case seriously and tell me to call the sheriff of his county, and give me the sheriff’s number even after I told them I was speaking from a different country and that this was an emergency.
- I post the sheriff’s number on the Misc. thread
- People tell me to quit worrying and that they’re 100% sure its a loop and he’s just fraudin’
-jjlee138 (Rep this dude) calls the Broward County Sheriff’s office and speaks to them about the situation along with a couple of other people. By the time I called, it turns out 3 people had already called them about it.
- People wait for the cops to bust in on the JTV cam.
- Some people start thinking nobody called the cops, at least 5 more people call the cops, they were told the cops were on it
- 25 minutes after the first call to the cops, the cops bust in. They cover the webcam
- People speculating whether he’s dead or not
- At this point of time a lot of people start deleting/editing their posts everywhere. PM me for the original thread content.
- Friends post messages on his myspace worried about him, no response from him.
- His best friend posts a thread on the Misc. and informs the people that he’s dead.
- Some people still think its a bluff

If you’re a parent, get to know what your kids are feeling.  Don’t let this happen to yours.
