wireshark-capture in web-ui

[m-uwh]

Hello,

I have seen at EVE-NG that it is possible to open Wireshark directly in the browser. Apparently a VM with Wireshark installed is started in the background and you can then start a capture without a Wireshark application on your own computer. Isn't this also a good idea for the GNS3 web client?

Hi,

You should be able to do the same by installing the GNS3 web client pack: https://github.com/GNS3/gns3-webclient-pack/releases/tag/v1.0.0b3

Then in the web ui, right click on a link and start a new packet capture. Select "Start the capture visualization program" to automatically launch Wireshark.

Hi,

the idea is that you don't need an installation on the client. Then it would be possible to access a Gns3-Server only via web-ui and capture packets. The Wireshark application would run directly on the Gns3-Server and the visualization of the application is displayed on the html5 web page e.g. via a vnc connection to the Wireshark application VM.

Hum sorry I overlooked that you said "directly in the browser". We definitely would like to do something similar but this will take some time.

Still having the same issue in Arch linux.

There may be a few web interfaces for Wireshark but haven't found anything that we could just integrate in GNS3: cloudshark is commercial and wireshark.io seems to be gone.

Please let me know if I missed anything interesting.

Mhm... I think EVE-NG starts a Docker container in the background, which then runs Wireshark. You would have to tell the container on which interfaces it should then capture, since you have initiated capturing on a specific link in the GNS3 interface. I could try to contribute, but I don't have much experience with this yet.
