Just because it bugs me to no end: thats the original purpose of a VPN, not some privacy snakeoil. That being said most host-discovery doesn’t work reliably, or is not implemented by most programs.

I am split here. I dont expect anyone to know the manages by heart, but at least doing a quick search should be possible. If that obviously wasn’t done I’m fine with referring people to the friendly manual.

I really don’t see a reason to write more just to summarise what has already been written. Is that toxic though? I don’t think so. If someone then says that they don’t understand what that reference means, I’ll gladly explain how manpages work and how to search for info. Teach a man to fish and stuff.

You might want to take a look at cage which has been designed for that.

That still requires some level of graphical session though
