I’ve read somewhere that GNS3 runs better on Linux and I had some spare cycles on a Hyper-V host. I configured a VM with 16GB of RAM and I was able to get GNS3 up and running on Ubuntu 14.1 using the steps I will be documenting below. Since we will be installing from the source files from the git repository on Github.com, you will need to install git: sudo apt-get install git ...

Even though the wizard warned me about placing WDS "RemoteInstall" folder on the System Volume, I went ahead and did it anyways. How hard can it be to change location? After Getting WDS working I needed some space to install some more images. I created a 100GB SCSI VHDX volume and added it to my WDS server as Volume E. wdsutil /Uninitialize-Server wdsutil /Initialize-Server /REMINST:"E:\RemoteInstall" So next time I disobey the wizard, my quick reminder of the steps to move the remote install folder to a new volume: ...

On the “System Authentication Servers” page in pfsense the example listed to add an Extended Query “Example: CN=Groupname,OU=MyGroups,DC=example,DC=com;OU=OtherUsers,DC=example,DC=com” was not working for me. This setting is required to authenticated only members of an ADS group. Worked nicely once I appended “memberOf=”. Level: Entire Subtree (but this can probably work at one level too) Base DN: DC=domain,DC=local Containers: DC=domain,DC=local Extended Query (checked): memberOf=CN=VPNgroup,OU=Groups,DC=domain,DC=local Kudos to BloodyIron!

I’ve had DD-WRT on my home router for awhile. DD-WRT works well but I want to setup some VLANS to play with some LAB configuration and the build of DD-WRT did not have the VLAN GUI. I had no success configuring this on the command line (could totally be me). I always wanted to try OpenWRT but I have had zero success so far loading it to any hardware. I came across this video on Youtube: ...

Operating Systems are tools in a toolbox in my view and over the years I have been reaching for Debian because it is a quick way to get things done. I especially love the Network Installation, mostly because I hate burning CDs :-). Net install ISO are under 300 Megs and coupled with PXE boot, this is a quick way to get a desktop up and running. Download your netinstall image Boot-Up and Install the base system Select Additional packages Configure system as required Once the base system has been installed, all additional packages are download from the repositories and install. If you have a slower connection NetInstall would be very painful (slow). ...

VirtualBox is a viable LAB option for Certification study. Personally I would prefer to run Hyper-V or XENServer but those solutions are a bit resources heavy for a home LAB. VirtualBox is prefect for older aging hardware. ========= Install VirtualBox ============ On Debian Wheezy I learnt the hard way that the packages in the distro repo are dinosaurs, which I could not get to work with PHPVirtualBox. I installed VirtualBox from the Oracle repo. ...

I’m having some issues with deploying Dell Optiplex 3011 Windows images using Windows deployment services. What should be a quick win has turned into an head banging exercise! From the onset I was very sceptical about these systems so I’m not surprised that it has been such a pain. http://www.youtube.com/watch?v=Mkl8kCwvpm0 I am using WDS (2012 Server) with the Windows 7 Boot image. I have injected the drivers for the realtek network card and for some reason the drivers will not load in WinPe. ...

I can’t keep up with all the passwords! There are too many passwords for me to manage, I used to find myself unable to access systems. Passwords are especially annoying on mobile devices with the tiny keyboard. I wanted a solution that works on both the Desktop and Mobile devices. Lastpass is a password management option that I have used in the past. They have a free service but you have to pay to use there mobile apps which is not bad however I never liked the user interface on their Android App. ...
