For 4 hours I have been trying to get GNS3 to work on my Fedora 16 VM.

I have GNS installed but when I test dynamips all I receive an error message "failed to start dynamips"

I tried service iptables stop but this did not help.

I have tried the RC2 and RC3 beta version of dyamips.

I am using GNS3-0.8.2-BETA2 for GNS.

Is there an rpm anywhere?

Any assistance would be appreciated.

Why use gns at all? Just go direct with dynamips

I guess using GNS is a habit of my windows ways.

At the moment I am not doing anything super intensive so the overhead of GNS is not that big of a deal and the ease of usability is a huge plus.

I figured out why it was not working.

At first I had tried RC3 and GNS said "unable to determine version of dynamips"

I downloaded RC2 but forgot to set the +x.

I set +x and now it works.

I am still having a lot of problems.

To run just dynamips I need dynagen and dynamips itself correct?

Thanks

Yup, that's it

When I try to start dynamips I receive the following error

Below is my .net

Is there something wrong with my .net?

Thanks

You would run dynamips first then dynagen calls the .net

e.g.

[root@F16 ScriptTest]# dynamips -H 7200
[root@F16 ScriptTest]# dynagen scriptTest.net

I ran into the same problem a bit ago on a fedora 14 box. You have to make sure that under
"edit ----> Preferences -----> Dynamips ------> 'executable path' inputbox" the file being pointed to is both the dynamips executable file, and your account has permissions to access it

for reference my executable is called
dynamips-0.2.8-RC3-x86.bin

you can find any dynamips .bin files by runing

find / -name dynamips*.bin

I am able to get gns3 working doing this, but I am unable to console in using the gnome terminal, I have to use putty.

I select gnome from the list, hit use, then apply, then right click the router, then console, and nothing happens.

Any ideas?

As far as the dynamips problem goes when launching from the console, I will have to try that tomorrow.

Thanks for all the help.

Its not doing anything because dynamips is failing to start.

Lets talk in pictures, I like pictures

I apologize for the confusion but GNS3 runs fine.

When I test dynamips it is successful.

I can use routers and config them in GNS, its just that in GNS I cannot use the terminal, I have to use putty.

When I set GNS3 to use gnome terminal (gnome > use > apply) and right click to console into the router nothing happens.

When I set GNS3 to use putty (putty > use > apply) and right click to console into the router putty opens and I can configured the router.

Thanks
