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!
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.
You can download the script here, just rename to ps1 and run from a machine with exchange 2010 EMC installed.
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 🙂
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 The PIX is out of life as far as Cisco is concerned and had been superseded by the ASA line of security devices.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!
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 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.
