Ubuntu Idyll Cisco Study Environment

I have written a few posts in which I mentioned the amazing GNS3/Dynamips/Dynagen set of tools that enable you emulate a Cisco network …. also a great too used to prepare for the Cisco CCIE lab exam [Professor of Internetworking]

Here are a couple of things I have used that make creating and using labs a nirvana experience in Ubuntu … [constant flow for those who understand Emotional Intelligence]

  1. Because I hate having multiple console windows open, one for each router which is the default behaviour of GNS3, I wrote the script [tamonet.sh] in the previous post that essentially takes as an arguement your topology (.net) file and then opens each router console in a separate tab in gnome-terminal.
  2. I modified my gnome-terminal profile so that my background is translucent. That way, I can have a document (e.g a workbook) I refer to in the background and read instructions or make references without having to switch windows.
  3. Initially, to launch my lab with my tamonet.sh script, I would open up either a terminal or the RUN application box [Alt-F2] and issue the command …. that is until I discovered awn-terminal. Boy! …. first of all, AWN is a cool dock application for Ubuntu and one of its applets is a nifty cool terminal that you just click and it pops up a next-gen-like translucent terminal. You just type in your command and as soon as u move focus from it, it automatically closes … no clutter on your desktop!!
  4. And finally … when I am doing such work, I play music. Mozart is ideal for me but I generally prefer any kind of music without vocals. It is the vocals I find distracting. So for me, to complete the ensemble, it is Mozart, Beethoven, Tchaikovsky or soundtrack music [Prison Break, Stargate etc]

Given what I mostly do these days [putting in my 10000 hours to master my craft as a network engineer] and my passion for Ubuntu … I enjoy every single moment I spend building and executing scenarios and everyday, I say thank you to the guys who selflessly make all this possible …and it reminds me to keep sharing what little I know. Happy Valentines day guys and babes … do spend vals with someone real … far away from your laptop ok?

  1. Found your site fr ntop’s link & loving the guide! Thank you.

    I feel your pain w/ juggling terminals. I replaced “Term” w/ “Terminator” (http://www.tenshu.net/terminator/) .. does true transparency also. I also use “Guake” for quick’n’dirty uses, bound to F12.

    I wonder if you could adapt your .sh to some sort of keystroke recording method to have Terminator pull up the same panes for layout? I know it supports tabs, but would be a feature I’d consider essential.


  2. Hi all!!!!!
    I agree, intercourse is a vital recipe to a successful marriage. I guess you can say it to him in a non-accusing manner (you don’t want him to feel that your pointing out that there’s something wrong with his masculinity) and let him know in an assuring way that the reason why you are suggesting that to him (to seek medical help) is that you want to enjoy sex with him…purchase generic!!!!!
