I just run pwgen -c 6 -0 and picket one that I liked most.

I did same thing when I was picking my Wifi home network name (Wahthahv)

Regardless of what I think about cellphone usage in the classroom. I don't think this is something that UNESCO should have saying in. And definitely not be able to ban.

When I had home lab I used to use racktables - https://www.racktables.org/

but I'm not sure if this is what you're looking for.

Thanks for the tip. I didn't find there what I wanted, but nevertheless, it's a very interesting site.
