DNS service: dnsmasq

Hello, so I've having some issues in regards to having my MAC address randomized upon making a connection. I have alright setup my auto-connection with nordnm sync -uka blah blah blah, but after this running nordnm mac --random will always output two things; the first being irrelavent to this issue

[ERROR] [nordnm.utils]: Could not check PyPi for latest version.

And the second

[ERROR] [nordnm.networkmanager]: Could not save MAC address configuration to '/usr/lib/NetworkManager/conf.d/nordnm_mac.conf'

Ok, no problem. Probably because the network interface is busy. So let's just try stopping dnsmasq and NetworkManager and changing the MAC myself with macchanger.

> sv stop dnsmasq && sv stop NetworkManager
ok: down: dnsmasq: 0s, normally up
ok: down: NetworkManager: 0s, normally up
> sudo macchanger -r -b my_interface
Current MAC:   ac:2b:6e:8e:61:dd (unknown)
Permanent MAC: ac:2b:6e:8e:61:dd (unknown)
[ERROR] Could not change MAC: interface up or insufficient permissions: Device or resource busy

Hmm that's weird, let me try seeing if anything is doing something with the interface.

> ps aux | rg my_interface
root      2842  0.0  0.0  10172  4104 ?

Hmmm, why is dhclient running? I don't use that or dhcpcd. Let me just kill it and try again.

> sudo pkill dhclient

> ps aux | rg wlo1
bigdaddy  6499  0.0  0.0  24716  6788 pts/2    S+   10:36   0:00 rg my_interface
> sudo macchanger -r -b my_interface
Current MAC:   ac:2b:6e:8e:61:dd (unknown)
Permanent MAC: ac:2b:6e:8e:61:dd (unknown)

Alright well that's annoying. Normally, before I used this tool, all I did was run sudo sv stop dnsmasq && sudo sv stop NetworkManger ; sudo macchanger -r -b wlo1 ; sudo sv start dnsmasq && sudo sv start NetworkManager and that worked fine, and then I'd connect to a server.

So this tool is running some other process that's keeping my network interface busy. I'm no expert by any means at all, but my only other guess might be the dbus-daemon.

So until I know what else is interacting with my network interface, I can't randomize my MAC address.
