FreeCCNAWorkbook.com in Packet Tracer - Section 4

 on  with No comments

In this previous post, I began to look into working through the Free CCNA Workbook in Packet Tracer.  I had worked through the first three sections, and found that while there were some unsupported commands here and there, there was not anything missing that I would consider to be a show stopper so far.  So moving along, I have worked through Section 4 tonight and here's what I found. For reference, I am using the latest version of Packet Tracer for Linux available from the NetAcad website at the time of this writing, which is version 6.2.  Your results may vary on the Windows version, but I doubt it.

FreeCCNAWorkbook.com in Packet Tracer Through Section 3

I had a discussion with somebody on line a while back on the feasibility of working through the labs at freeccnaworkbook.com using Cisco Packet Tracer. After a little back and forth and a lot of thought on the matter, I decided to give it a try rather than continue to speculate. Since I haven't used the program in years, I logged into my NetAcad account and downloaded the latest version (6.2.0.0052) and installed it on my desktop. And no, I will not provide you with a copy, so don't bother asking.

Using the GNS3 IOU VM on Hyper-V

I wanted to install GNS3 on one of my VM hosts because I leave those running and it would be convenient to have my topology always running.  Unfortunately for this idea, the VM hosts are already running Hyper-V, and as we all know, Hyper-V and VirtualBox do not play together nicely. So I started thinking about how I could get the IOU VM running in Hyper-V rather than VirtualBox. The problem is that every time I tried to put the VM on anything but a host-only network, IOU devices would not pass traffic to or from any non-IOU device. Normally I just use VirtualBox because it works, and it integrates nicely with GNS3. So after a lot of tinkering, here's how I got it working.

Windows 2000 Guest on Hyper-V 2012

I've got a few Windows 2000 Server virtual machines that were running on VirtualBox that I wanted to move to Hyper-V on a Server 2012R2 host. Of course there are no drivers included in a stock install of Windows 2000, and the Guest Additions CD that comes with 2012R2 no longer has Windows 2000 drivers. So what to do?

A number of forum posts suggested getting a hold of a Server 2008R2 Guest Additions CD and installing the drivers off of that.  I have a Server 2008R2 box, so it wasn't much trouble to install the Hyper-V role and then grab the .iso out of c:\windows\system32. Unfortunately, the drivers would not properly install and rebooting lead to an immediate blue screen, even when attempting to boot into Safe Mode. This was a test VM that I broke, and I don't care about it enough to troubleshoot. On to plan 2 for the next one.

For the second attempt, I exported the VM and moved it over to the Server 2008R2 box. Once there, I was able to attach the Guest Additions CD and the drivers installed fine. And for the final piece, moving the VM (with 2008R2 guest additions installed) back to the 2012R2 host did not appear to break anything, though there are a ton of unknown devices listed in the device manager now. Mouse, keyboard, video, and network are all good, so I'm not going to bother with the unidentified hardware at this point. So the bottom line is that the legacy 2008R2 guest additions work fine on 2012R2, you just can't install them while the guest is still sitting on 2012R2.

So why Windows 2000? I've got a couple of older apps that don't run well on 2008 or higher. If I'm going with an unsupported OS, I might as well go with the one that I can run comfortably in 128MB of RAM and probably less. There's just never enough RAM to go around when you're virtualizing.
