As a follow up to my previous post of the above topic, I finally put together a script. I have two scripts, one specifically written for the Internetworkexpert Dynamips topology. The second one can will log into any topology – it takes the name of the .net file as an argument for example
$./tamonet.sh BGPlab.net
Just copy this code, put them in a file with the .sh extension and make then run them from a command line AFTER you have started your routers in GNS3
<———————————————————————————————————————->
#!/bin/bash
#tamonet.sh
# The purpose of this scrip is to launch all running Dynamips router consoles in such a way that all consoles exist
# as tabs in a single terminal windows, rather than the
#default behavior to open multiple windows that just clutters the desktop.
#Script written by Mukom Akong TAMON [mukom to tamon at gmail dot com] …..
#Use and distribute freely …. just give me credit for creating it ok? … 
#Save this with an sh extension, make it executable and then you can run either from
#inside an existing terminal or you press ALT+F2 and then run it. You must pass it the name of the .net file of your current lab
#e.g ./tamonet.sh BGP-Lab01.net
#It is best if you copy the script so it is in the same directory as the directory in which the .net file is.
#Obviously, this script only works for Linux distributions that are using GNOME eg Ubuntu.

I appreciate any modifications …. and this works for me … so I don’t have to get KDEbase libararies just for konsole4KDE. I hope u enjoy it.
The second script I developed from ideas i saw online …. you really shouldn’t need it cos it only works for the Internetworkexpert .net files.
