Did you experience the following problem?

telnet 127.0.0.1 2008 ; exitTrying 127.0.0.1…Connected to localhost.Escape character is ‘^]’.Connected to Dynamips VM “R1″ (ID 8, type c2600) – Console portPress ENTER to get the prompt.

It stops response or shows “**** Unknown IRQ ****”. Which IOS version are you using?

Thanks,
Aqua

Is there anyone experience the same problem?

Great post. I am pretty versed with Dynamips and now with GNS3, it makes things a whole lot easier. I have been running GNS3 on my Mac Book Pro with Lion, and memory wise it does a fabulous job. I have the 4 GB of RAM and can run about 10+ routers in a full MPLS SP and Customer configuration, using backup DMVPN links, etc. Its amazing how well Mac OSX Lion handles everything.

My main issues have been trying to get the ASA simulated using Leopard and now Lion. It’s been a huge ordeal. As I have been reading through many blogs at GNS3.net and other sites, the issue now has gotten worse. Have not been successful in getting the ASA to work. The PIX was working before, but now with all my QEMU tunings, that is no longer working.

I just curious if anyone on this post has had any success simulating ASA on GNS3 with Mac OSX Leopard or Lion?

Thanks!

Jorge

In that post, I documented what I did to get it work on Lion and also wrote some scripts to get you going with the permissions and so. 

I am using the same version of GNS3 and Lion as you do and have no problems at all in opening a console window from within GNS3.

Good luck

Cannot start /usr/bin/osascript -e ‘tell application “terminal” to do script with command “telnet localhost 2000 ; exit”‘: No such file or directoryI can Telnet to the virtual router, but access thru GNS3 isn’t working.Any ideas?Thanks,Kevin

I’m running OSX 10.7.2 and installed GNS3 0.7.4. Dynamips can start and the IOS image is loaded.
But when i want to open a Console session nothing appears. No error and no terminal window?

I use the standard command:
/usr/bin/osascript -e ‘tell application “terminal” to do script with command “telnet %h %p ; exit”‘

Do you have any adea what can be wrong?

Tank you,

Kevin

telnet 127.0.0.1 2008 ; exitTrying 127.0.0.1…Connected to localhost.Escape character is ‘^]’.Connected to Dynamips VM “R1″ (ID 8, type c2600) – Console portPress ENTER to get the prompt.

i hit ENTER but nothing happened, anyone can help? the dynamips is successfully tested

In windows version that is possible via Loopback Interface. I’ve tried it but no success.

Thx for the great post!

sorry for my bad english

Can anyone help, I’m new to Mac OS and it’s killing me not to be able to run GNS3

I’m running OSX 10.6.4
I’m trying to install the GNS3 v0.7.2 DMG package from gns3.net.

I get the “Can’t start dynamips on port 7201″ message whenever I try to add a router to the network.
I get “Failed to start Dynamips” when I try to test Dynamips.

When I run GNS3 is does not say anything about installing Dynagen (as you state in the procedure, “Now you can run the GNS3 and it will tell you to install Dynagen. Dynagen is a python wrapper that simplifies the dynamips emulator.”)

Any idea what i’m doing wrong?

Thank you.

I tried this /Applications/GNS3.app/Contents/Resources/dynamips-0.2.8-RC2-OSX-Leopard.intel.bin
but still red error “Failed to start Dynamips”

How can I make it work? I am not able to login as root to my macbook pro, could that be the problem?

Thanks a lot,

Hale

I cant seem to the get the GNS3 running on my MACbook 5.1 aluminum unibody with 2.0 gHz , 2.0GB DDR3 OSX 10.5 . I am getting an error ” GNS has encountered a fatal error, and will now terminate.”

I’ve checked the console and saw the line ” /library/Frameworks/Python.framework/Versions/2.6/Phyton: No matching architecture in unversal wrapper”

Do I need to do anything else or did I missed something. I ended reinstalling my OS but I am still getting the same error.

I used the GNS3 from this site “http://downloads.sourceforge.net/gns-3/GNS3-0.7.2-intel-x86_64.dmg?download”

I also tried to use ” http://blog.gns3.net/2010/03/how-to-run-gns3-on-mac-os-x/” but I stil cant get it to work.

Hope someone could help

Really great post.
Simply put – this is one of the best guides I have seen.
Really descriptive and puts everything into context.

I have been able to setup GNS3 on my Mac now.

Thanks and Great job!

I’ve used the directory suggests by Greg /?Applications/?Dynagen/?dynamips in gns3, still the demon won’t start. In fact in this directory there is the script “Dynamips server”. This script starts the demon, so the command telnet localhost 7200 works.

But
1. if I launch manually “Dynamips server” I’ve an error in gns3: “service just started on port 7200″ and gns3 try to start the server on the port 7201
2. obviously even if the server starts on port 7200 i can made a telnet connection but I’ve to configure manually the cisco emulator without the graphic interface of gns3 but using text command to create the router and the link.
