Dynamips router without private config: Save doesn't work #165

Closed ghost closed 9 years ago

ghost commented 9 years ago

GNS3 V1.3.2, OS: OS X 10.9.5 Topology: 2 x 3725 screenshot

When using startup and private config, all is fine, saving the configuration with save-project or right-click-save-config works fine.

Then I removed the private config from the router template. dynamips-router-config I recreated the project with this new router template and started it, no problems. Routers are running fine.

The save-project seems to work (no errors in console window), but only the startup-config of the first router is saved.

When I use the right-click-save-config the startup-config is saved, but not the private config and an error is shown in the console window "Server error from 127.0.0.1:8000: R1: Could not save the private configuration /Users/behlers/GNS3/projects/test/project-files/dynamips/: [Errno 21] Is a directory: '/Users/behlers/GNS3/projects/test/project-files/dynamips/'"

Here the output of the log: a) save-project

This should fix things: https://github.com/GNS3/gns3-server/commit/71e2586e176232f574b14be8d03c0d9ccd32daa6

Everything works on my side but this will need to be thoughtfully tested.

I just tested with the current dev version on linux (on OS X I try to stick with the official version).

While I haven't found a problem, when the private config is empty, using an empty startup config shows some unpleasant side effects.

First of all it takes about 100 secs until the initial system dialog starts (on c3725-adventerprisek9-mz.124-25d). I haven't found anything in the logs, that explains this long delay.

Furthermore the IOS I used doesn't see the private config, when the startup config is empty.

As GNS3 and the router works fine, it's probably an issue of the used IOS.

Well I think this is an IOS problem, it is the same with IOU, it takes longer for a device to boot without a startup-config.

Furthermore the IOS I used doesn't see the private config, when the startup config is empty

Unfortunately it looks like this is a Dynamips limitation. I'll investigate someday ;)
