Thanks for wanting to help and I looked and looked but could not find what you guys refers to.
I use KDE CE is that one not different from the standard version?
I have to go to bed now but look tomorrow again.
There is no built in firewall in kde the How to told me so I sudo apt-get the one they recommended.
I don't remember the name. gfow or similar 4 chars. I am rather sure it had at least g and f in it.
it is local time 23 39 here so have to go up early Friday morning to travel.
thanks indeed for wanting to help me out. Am I really alone wondering about it?
I suddenly saw that KDE had a search an look what I ahve found by
Guarddog that says it is not sure it is enabled ...
So I look at it tomorrow. So it was easier than I thought.
