"Dynamips is a Cisco router emulator written by Christophe Fillot. It emulates 2691, 3620, 3640, 3660, 3725, 3745, and 7206 hardware platforms, and runs standard IOS images. " – dynagen.org

This software is awesome. 2 FAQ’s though:
1. How would you upgrade the flash and memory in the simulator? This is required for some IOS’s
2. If I wanted to put 2x IOS’s on the flash how would the simulator let me do that?
Thanks

You are the man

Upgrading the memory in the Emulator is as simple as changing the ram option in the .net configuration file. To upgrade the flash, you would just need to specify a different size with the ‘dd’ command.
If you want to practice copying images to the flash, you would first need to format the flash inside the router … I believe the command is ‘format flash’ or ‘format disk0′. Then, you should be able to store images in flash.

Isn’t the “:” required after device name, As in “format flash:” ?

When I follow all step by step instructions for installing Dynamips on Ubuntu and at the end when I run it I get a “No such file or directory”
Can you help with this?

What command did you type just before getting this error message. Here are a couple blind guesses as to what might be the problem…
1) You are signed in as root with the sudo -i command in Ubuntu or “su -” in Redhat Based systems.
2) When you created the symbolic link for dynamips or dynagen, you did not create the link in the correct directory.

When instaling on ubuntu you may have to type sudo before running all of the commands during the installation process.

Can I run this on Gentoo? This is one of the most stable flavours of Linux out there.
October 4th, 2007 at 9:36 am
Yes, it should work on Gentoo.
October 8th, 2007 at 6:25 am
Thanks for letting me know. As Im running Quad-Core Q6600, I need 64-bit support. I just checked and Im not sure about the stable versions for Gentoo. Ubuntu seems like a good choice seeing as its being used on the excellent tutorials. So I will look at a server version.

Hi, is it necessary to do a “idlepc get R1″ for each router? I just did it for two routers in the same lab, what is the difference?
Thanks

When I try to run dynagen simple1.net, I get the following error message….
Traceback

from console import Console
ImportError: No module named console
Have you ever seen or heard of this type of error message? What can I do to correct this? Thanks for the tutorial, it’s great.

Dynagen starts up fine, but when I do dynagen simple1.net I keep getting all these hex numbers constantly loading on the screen and they never stop, looks something like this:
MIPS64 Registers:
zr ($ 0) = 0×0000000000000000 at ($ 1) = 0×0000000000000000
v0 ($ 2) = 0×0000000000000008 v1 ($ 3) = 0×0000000000408103
a0 ($ 4) = 0×0000000000000002 a1 ($ 5) = 0×0000000000000000
a2 ($ 6) = 0×0000000000000000 a3 ($ 7) = 0×0000000000000000
I have to kill the dynagen process to stop it from going, any ideas?

Cheers !

But why did you have to crash the IOS if you also had a couple IOS’es that worked?

fantastic tutorial…installed perfectly for me. However, any idea on whether there’s graphical based design tool which can link to dynagen and use it to create topology scenario’s which i can configure? e.g like Boson NetSim Topology?

Toma,
I think you are looking for the gns3 section.
