Cloud PBX: Polycom VVX Master Directory

Sun, 10 Sep 2017 20:38:59 +0000

Reverse number lookup in Skype for Business online (cloud PBX) doesn’t give you much control. If you are deploying Polycom VVX phones you can get around this with a directory file.

Exchange 2010: Automated Firewall Rule Generation 1.2

Wed, 20 Jul 2011 16:35:08 +0000

I made a few changes to this script to make it more modular and to allow for more exceptions in regards to DAGs and sites. Enjoy!

Exchange – Notify Forwarded Accounts Script

Mon, 10 Jan 2011 20:00:19 +0000

In cleaning up a large number of disabled user accounts in AD I wanted a way to notify a large number of users specifically that they were being forwarded e-mail from another account. This was part of an effort to clean up AD a bit before moving everyone over to Exchange 2010 but it can be used independently of any one project as part of a general AD maintenance plan.

New Project: bridgetun.sh

Wed, 06 Aug 2008 16:04:41 +0000

I’ve been trying to get this one out for weeks but have not had a whole lot of time to do so. I’ve decided to drop what I have completed out there for those who may be interested. Simply put bridgetun is a convenient way to create tun interfaces and to bridge them (and other interfaces) together. I’d give it a once over and see if it helps with any of your dynamips labs. I’ll try to have a quick howto and explanation of why it would be useful as soon as I can but I give no promises 🙂

GNS3 on Ubuntu 8.04 – Pemu Guide

Mon, 07 Jul 2008 14:41:08 +0000

Ok, so far we have gone through the hoops to get GNS3 with dynamips/dynagen working nicely in an (almost) fully contained directory in /opt. We then went through choosing an IOS image that is right for you, if you actually have multiple legal images to choose from of course. Now lets setup a pix firewall. The PIX is out of life as far as Cisco is concerned and had been superseded by the ASA line of security devices. But, there are still a lot of the PIX around and the concepts haven’t changed too much between them. So let us go through the motions already!

Ubuntu Server 8.04 Post Install Tip #2: Shell Goodies

Thu, 03 Jul 2008 17:17:38 +0000

OK, I promised a friend some time ago that I’d post all of my post-install procedures and I’ve not quite followed through with that so I’m doing a few before finishing up my three part post on the “Home Hacker’s Network”. These are all just little hacks I’ve come across and modified to suit my needs. I like this one a bunch as it gives me a nice shell prompt when I login as well as when I use screen (although the gnu screen configuration part is mutually exclusive to the shell modification part).

So lets get started…

GNS3 on Ubuntu 8.04 – Install Guide

Thu, 12 Jun 2008 13:53:54 +0000

GNS3 is a frontend for dynagen (which is a scripting language for dynamips). Getting it to work nicely in Ubuntu was a bit of a pain in the arse but I was able to get it to work in a manner I’m happy with. This setup will essentially encapsulate a large portion of the install to one directory in /opt. Some libraries and executables will be installed through apt though, but not many. I previously wrote part of a writeup for this on Ubuntu 7.10, I’d ignore that in favor of this one which is much more up to date and polished.
