GNS3 can't connect to localhost:3080

Hello Everyone,

I recently fresh-installed Arch using the Official Guide.

I want to run GNS3 Network Simulator on the computer but it says it can't connect to localhost on port 3080


I tried installed Apache server and enabling httpd.service
but then I get this :

Local server process has stopped

P.S :  I used this guide to install GNS3 and the other required dependencies

Re: GNS3 can't connect to localhost:3080

Please use 'code' tags, not 'quote' tags.

You are missing a dependency:

pkg_resources.DistributionNotFound: The 'aiohttp-cors==0.7.0' distribution was not found and is required by gns3-server

Re: GNS3 can't connect to localhost:3080

Rather than following that dubious guide which tells you to install an AUR helper using a poorly maintained and regularly broken unofficial repo, try the Arch wiki: https://wiki.archlinux.org/index.php/GNS3

Mod note: Moving to AUR Issues.


Sakura:-
Mobo: MSI MAG X570S TORPEDO MAX // Processor: AMD Ryzen 9 5950X @4.9GHz // GFX: AMD Radeon RX 5700 XT // RAM: 32GB (4x 8GB) Corsair DDR4 (@ 3000MHz) // Storage: 1x 3TB HDD, 6x 1TB SSD, 2x 120GB SSD, 1x 275GB M2 SSD

Making lemonade from lemons since 2015.

Re: GNS3 can't connect to localhost:3080

Hi
I finally got success installing GNS3 and VMWare Workstation Pro on my laptop
However, When I try to integrate them and run, I get :

Version mismatch with vmmon module: expecting 392.0, got 385.0.You have an incorrect version of the 'vmmon' kernel module.Try reinstalling VMware Workstation.

How do I get vmmon 392 ? 

The AUR package that provides this module can't be downloaded on my computer because it lacks signature
I installed v 385 using a tarball that i found somewhere, but I think it's for VMWare Workstation 14 .

Thanks

EDIT  :

I used vmware_patch from AUR but still no luck
SAME ERROR

Re: GNS3 can't connect to localhost:3080

I fixed it with a complete fresh start following the Arch Wiki Guide

Guys, don't look elsewhere!
