GNS3 0.5 beta

I'd already installed dynamips using macports so I already had dynamips version 0.2.8-RC2-x86 in /opt/local/bin

I installed GNS3 from the .dmg
In the Preferences > Dynamips > Test it always says "Failed to start Dynamips"
If I start dynamips externally I can use GNS3 but I'd like to learn why I can't use dynamips within GNS3
In the Preferences > Dynamips > Executable path: I tried changing the path to /opt/local/bin/dynamips but I had the same issue

Whenever I start dynamips outside GNS3 in the shell I have to run dynamips as the superuser i.e. cd /tmp; sudo /Applications/Dynagen/dynamips -H 7200

1. Does GNS3 need to start dynamips as the superuser?
2. How does GNS3 start dynamips as the superuser?
3. Am I missing a step which will allow GNS3 to start dynamips?

Thanks in advance!

Caleban,

I just went through this with a co-worker. What worked was to add a .bin extension to the dynamips executable.

If you browse to the executable from the gns3 preferences, you'll see that, without the .bin extension, the executable is greyed out. Once the extension is added it's available for selection.

Chris.

Thanks! It worked!

Try setting the working directory for dynamips within GNS3 to something that isnt /tmp but that you can actually write to.

For example, make a tmp directory under your home directory and use that.

This is what got me past the "Failed to start dynamips" problem on MAC OSX ( Snow Leopard )

I dont know why this was necessary ( since even my normal user account can write files in /tmp ) but it got me working.
