Well, i do not find it anywhere in the net, but there was about 1990? a nice joke, what is a save computer? and it was something like this : if i have a computer i will put it into the middle of my cellar, i will switch it off, i will put out the door and will use concrete to fit into the door-hole, will cut all power lines off... but even then i am not 100% sure. and by the way, there was a myth, i never get if it was true, that in commodore amiga computer there was a virus programmed which was able to use the battery of the clock to get resistant inside the memory. so, why discussing here about save NETWORKS ?????? a network is per definition ALWAYS unsafe. this is written from a guy who do not use use a wifi, only for guests with a extra internet router, not connected to the main network. and i do not own a own mobile phone because of all the insecure stuff (but i am thinking about a fairphone or something like this with a opensuse on it). ..... and my brother tell me always, even if you not have a mobile phone the mossad, the chinese and the usa know where you are. really? : yes, the check where is no mobile phone in germany and exact this is your position i am lost.... ;-((( simoN ps: i always run firewalls in my networks, and i use nfs to get through this firewalls, using fixed ports, even nfsv3 could work with fixed ports, (it was not necessary with susefirewall), but now with firewalld. i think i remember, i have written it somewhere here in the useres@ list how to do. -- www.becherer.de
