Hi

Can i have more details of your topology ? I will could reproduce it OS (Ubuntu 18.04.6 LTS on Client and Serveur ?) / vwifi-client and vwifi-server on the same guest ? IP or VHost ? Which wifi software do you use ? Wifi config ?

Could you not use a newer version of Ubuntu ?

174high commented 1 year ago

Environment: ubuntu-18.04.5-desktop-amd64.iso

I ran vwifi-server , vwifi-client in different virtual machine nonetheless they are in the same domain . vwifi-server and vwifi-client can connect with each other . I set up 3 virtual machine . one was as host , one was a AP , one was a STA . when STA scan , it has result . when connected to AP , it crashed .

but anyway , could tell me what version you are using ? I reckon you don't need reproduce it .

I didn't see that coming that it crashed using a little bit older version of ubuntu .

Raizo62 commented 1 year ago

vwifi uses the kernel module mac80211_hwsim. This module has evolved a little over time. You can test with the last stable distribution(Debian/Ubuntu/...). I use the Debian 11 bullseye. vwifi is also already installed and configured to use on LiveRaizo.

174high commented 1 year ago

OK , I am using ubuntu 22.04 for test . I'll keep you in the loop if nothing inferior happens .

It crashs again . I reckon your driver is imcompatible with Ubuntu . It scans well therefore i think the topology is correct basically .
Anyway let me try our workable image .

174high commented 1 year ago

BTW , I don't know how to use your virtual machine . I can't figure out how to connect the internal nerwork .

It crashs again . I reckon your driver is imcompatible with Ubuntu .

It is strange because i believe that it is the same kernel as Debian. I will investigate.

Raizo62 commented 1 year ago

You are right. I can reproduce the crash with ubuntu 22.04

Raizo62 commented 1 year ago

I believe that i found the problem : I suppose that you have not changed the MAC addresses of the wlan interfaces before to use them with Network GUI of Ubuntu ? I have used "macchanger -a wlan0" (from the package macchanger) before, and the 2 ubuntu are connected without crash.

Could you test ?

174high commented 1 year ago

Dear Raizo62 It's workable now .

Thanks

Raizo62 commented 1 year ago

Or, don't use the same wlan interface with the 2 Ubuntu guest (so, they don't use the same mac address)

Raizo62 commented 1 year ago

Thank you for your help.
