Welcome to Part 2 of the dynamips,terminal servers and virtual rack tutorial. This time we are configuring 4 virtual racks. Each rack consists of 9 routers, 4 switch and a fully meshed frame relay cloud.
The virtual racks are controlled with dynagen and each user has their own automatically created .net file and seperate working directory so they can save their work. If a user access a different rack. The control script with rewrite their .net file with values for the new rack. So the user doesn’t any difference except for the terminal server address changing. Curious? read on for the howto.

I got back  from Melbourne about 5 hours ago now.7 hour drives suck on the return journey.  Spent the weekend catching up with Arden, Scott and some other people without pages to pimp. After a few drunken and sober discussions about my dynamips setup My head is crazy with ideas now. I was lying in bed rewritting the rackcontrol scripts in my head and then I think of …… videos?…
Yes video tutorials. So once I finish  part two of this series. ( next couple of days depending on work ). …

Welcome to Part 1 of another dynagen,dynamips tutorial. This time we are focusing on having Dynagen and dynamips start automatically on boot. I had a need for four terminal servers to start on boot. So I have included my .net, config files for the routers, init scripts and init config file. Read on to learn how to do this yourself.

My project for the last couple of days has been to setup a training environment for the other people I work with. I must say I’m happy with the results. I have setup 4 virtual racks, Each rack consisting of 6 routers, 3 backbone routers. Fully meshed frame setup. 4 x 3700’s acting as layer3 switches using NM-16ESW.  Each rack is managed individually with the capability to start,stop the routers remotely. Add in a Terminal Server for easy access and the fact that its automatically started on boot…. :).       Hopefully …

Here is the next mini ospf lab. This one utilizes multiple areas, more authenticate and some troubleshooting. Have a go and let me know what you think.
