In my etc/gufw folder I have an app-profiles folder which contains many txt files such as "overkill.jahnsonxi" and "blood2.jhansonxi" I'd really appreciate someone explaining what these are. I've opened some in PLUMA and they appear to relate to games, none of which I have installed. Here is an example:-
[0verkill] title=0verkill description=An ASCII-art 2D deathmatch game ports=6666 categories=Games;Action; reference=[http://artax.karlin.mff.cuni.cz/~brain/0verkill/index.cgi?mainpage 0verkill mainpage]
The second question is any thoughts as to how they arrived in GUFW, which I do have installed and running with the default settings."All out none in"
Finally do I need them?
I've tried unsuccessfully to find an explanation or even a mention of "jhansonxi" and his(?) profiles. I'm running Ubuntu MATE 16.04 on an ASUS F552L (X550LA) laptop.
