I am seeing another sys-net but it is appearing only after USB tethering when I click Service: sys-net > sys-net: XTerm.
It’s name is not exactly sys-net. Plz have a look at the image below.
Is it normal?
Thank you guys for your responses.
I found what is the problem. It is because of enabled ufw.
Surely, what I did may look like stupid to you.
I did it because I read somewhere that enabled ssh is a vulnerability point.
