JNCx Lab Topology

I have been trying to find out something like that in Internet and after couple of days looking I decided to make it myself. The configurations I am going the share are based on the topology below:




All this is Olive11.1R1.14 with recommended configuration of quad core CPU and at 8G ram and fast hard drive/SSD?  I am running that on FreeBSD 8.2/64x. All images are in separate folders called r1; r2; r3 etc. I believe the configuration example below should be enough for everyone who wants to run Olive to extend my config with more routers.

Installation is straightforward

cd /usr/ports/emulators/qemu ; make; make install

IOS on Unix (IOU)

source http://evilrouters.net/2011/01/18/cisco-iou-faq/ What is IOU? From the Cisco Engineering Education web site (a long time ago): IOS on Unix (IOU) is a fully working version of IOS that runs as a user mode UNIX (Solaris) process. IOU is built as a native Solaris image and run just like any other program. IOU supports all platform independent protocols and features. What operating systems does IOU run on? It is my understanding that, initially, IOU was Solaris (SPARC) only. Nowadays, however, there are also builds for OS X and Linux. Similar to dynamips, IOU allows you to build out a network topology on a computer, without the need for physical routers. This is useful for validating designs, proof-of-concept testing, and certification self-study. Is my system compatible with IOU? You will need to be running the operating system that your IOU image were built for, obviously. Other than that, there are no special requirements to run IOU. It is not very CPU- or memory-intensive, unlik...

Beijing - China

I am not sure how to describe Beijing China, maybe everyone who goes their simply use the world 'Amazing' because it will be nearly impossible to describe it. I had a personal driver and tour guide which significantly simplify my trip around.  Of course, it was a business trip and I didn't have as much time as I needed to see everything from Beijing but I will try to share couple of pictures and some of my impressions. I will start with the food.  I remember when I was younger there was so many Chines restaurants in the neighbourhood and I could eat Chines food everyday, and at every time - my parents were joking that I will became a Chines if I continue to eat only Chines, but it was so good and I didn't care ;-)  In Beijing I tried so many different things and I am amazed by the quality of the food, and most amazingly I didn't have any problems with my stomach - which was a good sign ;-) . I uploaded few photos from my album, which are from different places I ...
