Dynamips

[Rhodan]

Hi,

I'm just wondering if there are any users of Ubuntu that have installed and used Dynamips successfully on Feisty ? Are there repositories for it ?

Thx

Is this what you are talking about?
http://packages.debian.org/unstable/net/dynamips

Haven't used it, but you can get it from there.

Yeah that's it, just wondering if anyone here is using it under Feisty ?

Did you manage to install it?

I got the executable from this tutorial , it runs well if you know how to set the parameters, I got an IOS image a bit older than the one in the tutorial... the bad thing is that my laptop overheats quick when I run the simulator, I don't know how that can be solved.

Hi K84 ...

You must to configure idlepc. I use Dynagen, that is a front end for Dynamips www.dynagen.org try this.

Hi all,

Glad to share I did it . I got it working with bridging too . Dynamips&Dynagen just rock. I tested on feisty. I am far from expert, but would galdly help on this matter.

Hi

I have followed this blindhog guide and get dynamips to start but when trying dynagen simple1.net the message "could not open simple1.net" is shown?

Any ideas. I got dynamips/dynagen to work on Windows ok. If there is a better way and more straightforward way to install dynamips/dynagen please do tell.

Thanks

P.S. I didn't know how to stop iptables but don't know if this is the reason?

what about GNS3? Some might call it a bit "girly" but i still like making a topo map and then hitting 'run' instead of having to refer to a spreadsheet with 10 routers on it.

btw, speaking of which, any ideas as to how many routers a machine with 2ghz P4 and 2gb of ram can run in dynamips? my CCNP book has practice labs at the end of each chapter, but they all use about 6 or 7 routers... my laptop with 1.5ghz and 750mb of ram using XP can get a max of 4 routers, so i'm thinking my better equipped desktop running ubuntu 7.10 should be able to do at least double that.... i'll find out tonight though.

Hi geezerone ..

I think the problem is the path for the "image=" line on the net file. You must create a path where the IOS image bin file resides and give it privileges for read, write and excecution.

For example:

U could create a directory on opt whith the name images:

sudo mkdir /opt/images

Then copy or move ios bin file to that path (for this example i assume that the ios bin files exist on the default pathi for the user--in this case tony--):

cd /opt/images
sudo mv /home/tony/7200-AD.bin .

Then give it privileges to the user:

cd /opt
sudo chown -R root:tony images/
sudo chmod -R 775 images/

Now u can configure your net file with the right path:

[localhost]

[[7200]]
image = /opt/images/7200-AD.bin
# On Linux / Unix use forward slashes:
npe = npe-400
ram = 160

[[ROUTER R1]]
s1/0 = R2 s1/0

[[router R2]]
# No need to specify an adapter here, it is taken care of
# by the interface specification under Router R1tony@Kannon:/opt/dynagen-0.1

Try this and if u got a problem, please post the errors and net file.

Greetings !!! and sorry for my bad english.
