GNS3 Version: GNS3 v2.2.48 Operating System: OS: Ubuntu 24.04 LTS x86_64

Overview:

Anyone found a fix for Path Is Not Allowed bug whenever trying to open an old project or start a new project for GNS3 v2.2.48?
This issue happens on both my GNS3 servers running GNS3 2.2.48 on Ubuntu 24.04 LTS x86_64

Are there similar issues?

- Yes
- Were they resolved, no

[1] - https://gns3.com/community/support/the-path-is-not-allowed-permissions-error-linux [2] - https://www.reddit.com/r/gns3/comments/jf94t6/gns3_says_the_path_is_not_allowed/?rdt=41768 [3] - https://discourse.nixos.org/t/the-path-is-not-allowed-gns3/44796

How to replicate:

- Upgrade to GNS3 v2.2.48
- Launch GNS3
- Try to create a new project > I get the error.
- Try to open an old project > I get the error.

What was done to troubleshoot the issue [1]:

- Purge GNS3 files from problem device
- Reinstall GNS3 2.2.48 using: https://docs.gns3.com/docs/getting-started/installation/linux/
- Issue still persists

What was done to troubleshoot the issue [2]:

- Upgrade to Version 3.0.0 beta 3:
> https://github.com/GNS3/gns3-gui/releases/tag/v3.0.0b3
- Issue resolved

What was done to troubleshoot the issue [3]:

- Downgrade to Version 2.2.47:
> https://github.com/GNS3/gns3-gui/releases/tag/v2.2.47
- Issue resolved

What was done to troubleshoot the issue [4]:

- Running 2.2.48 as root appears to fix the issue as well:
> How to do: sudo gns3

Appears running gns3 --debug doesn't really provide much help but I found something odd.

I removed & recreated the GNS3 folder which contains the following:

GNS3 ls -la
total 31
drwxr-xr-x  7 <User> <Group>  7 Jul 19 10:59 .
drwxr-x--- 31 <User> <Group> 45 Jul 19 11:19 ..
drwxr-xr-x  2 <User> <Group>  2 Jul 19 10:55 appliances
drwxr-xr-x  2 <User> <Group>  7 Jul 19 10:59 configs
drwxr-xr-x  3 <User> <Group>  3 Jul 19 10:59 images
drwxr-xr-x  2 <User> <Group>  2 Jul 19 10:55 projects
drwxr-xr-x  2 <User> <Group>  2 Jul 19 10:55 symbols

I then recreated the folder structure with the same folders. However, whenever I try to create a project labeled "untitled" I get this error: - Project "untitled" already exists

We can see that the file "untitled" doesn't exist in the folder via the following output:

projects ls -la
total 10
drwxr-xr-x 2 <User> <Group> 2 Jul 19 10:55 .
drwxr-xr-x 7 <User> <Group> 7 Jul 19 10:59 ..

The GNS3 client is apparently trying to save the file somewhere else other than it's default path which is outlined below, verified from the - "gns3_server.conf":

images_path = /home/gns3s3/GNS3/images
projects_path = /home/gns3s3/GNS3/projects
appliances_path = /home/gns3s3/GNS3/appliances
additional_images_paths = 
symbols_path = /home/gns3s3/GNS3/symbols
configs_path = /home/gns3s3/GNS3/configs

I was curious and thought to check the WebGUI to see if maybe it was stored there and apparently v2.2.48 for me is trying to save files whereever the webclient stores them because we can see the untitled project lives there, which explains why I am getting the error I am getting when trying to create a "new" project titled "untitled":

Confirmed I can create new projects from the WebGUI & I can open "old" projects from the WebGUI:

When I try to create a new project from the GNS3 client targeting the name of one of the projects I created from the WebGUI I get the error mentioned earlier: - "Project "untitled" already exists"

Is there any workaround for this???

kakkotetsu commented 3 months ago

This case may be the same as the following issue. https://github.com/GNS3/gns3-server/issues/2403

The workaround is not to use systemd to start gns3-server.

@kakkotetsu - Thanks this worked!

However, it's not really ideal since it seems to have a different configuration than when gns3 runs with the service running.

A bit hard to explain but all my uploaded network devices were "wiped" when starting the GNS3 client without the gns3-server services running.

Also, if you have remote servers as part of your topology the local gns3 GUI running on your device doesn't appear to make a connection to the remote gns3 server.

So a few things breaks with this workaround, this is definately a bug because I moved both my servers to Fedora 40 as a test & installed GNS3 .48 and I had no issues.

However, I rebuilt my servers & reinstalled Ubuntu 24.04 LTS x86_64 & gns3 from the ground up and I ran into this bug again.

@grossmj - Sorry to tag you, but are you able to look into this bug?

WhatsTheIP commented 3 months ago

Update.

Uninstalled all of GNS3 components from Ubuntu servers & reinstalled.

At the prompt that asks for "would you like GNS3 to run as a service" select no

Issue appears to be resolved, thanks @kakkotetsu

@grossmj - FYI, additional context if you need it to troubleshoot.

@Lugib - Try this work around.

Confirmed the [BUG] - "Path Is Not Allowed" appears whenever you start the gns3server.service. Confirmed the [BUG] - "Path Is Not Allowed" disappears whenever you stop the gns3server.service.

Affected system: GNS3 Version: GNS3 v2.2.48 Operating System: OS: Ubuntu 24.04 LTS x86_64

Found a work around on how to resolve the issue while preserving remote server connectivity & keeping my topology & nodes intact.

I'm adding this as a note for now for historical purposes, updating the bug link below with my work around if others face this issue:

IMPORTANT:

1) - Make sure you kill the gns3server 1st before you attempt to run gns3server --local from the CLI.

2) - If you don't know how to do that, go down below you'll see where I identify if the gns3server service is running and how I killed it.

3) - You don't need to run --debug but I did it to troubleshoot the issue to see if the server or client returned any logs.

The current workaround is to not select "Enable the service" option when installing the package or edit the systemctl service file to add the --local parameter:

sudo systemctl edit --full gns3server.service

and change the line ExecStart=/usr/bin/gns3server to ExecStart=/usr/bin/gns3server --local
