Linux Mint 12 : How to install dynamips and gns3 ( Cisco Router Emulator )


Here’s an explanation of how to install dynamips and gns3 on Linux Mint 12.

# uname -ri
3.0.0-15-generic x86_64

# tail -1 /etc/lsb-release
DISTRIB_DESCRIPTION="Linux Mint 12 Lisa"


[ install dynamips and gns3 ]

dynamips is Cisco Router emulator and gns3 is GUI tool for dynamips.
# apt-get install -y dynamips gns3


[ initial setup ]

start gns3
$ gns3 &


do step1 ( configure working directory ) and then step2 ( load IOS )


step1 ( click OK. default settings )


step2

select the IOS image you want to run.
I used c3640-jk9s-mz.124-13a.bin.


click “Save”

drag and drop “Router c3600” icon like this.




start c3600

configure Idle PC

By default , the dynamips process uses around 100% CPU consumption.
# top -b -n 1 | grep dynamips
25472 hattori   20   0  363m 185m  65m S   99  1.5   3:17.27 dynamips


To reduce CPU consumption

select Router icon , right-click , Idle PC



Dynampis will calculate an appropriate Idle PC values.


Click “Apply”

After configuring Idle PC values.
# top -b -n 1 | grep dynamips
25472 hattori   20   0  363m 185m  65m S    8  1.5   6:57.80 dynamips

CPU consumption is 8%.

Configuration file is stored under .gns/ directory. ( gns3.ini file )
# head -5 /home/hattori/.gns3/gns3.ini
[GNS3]
version=1795
lang=en
project_startup=true
relative_paths=true

  4. nnn , I think I have not added an extra repo for dynamips.
