thanks for your time to answer my questions. 



Now nearly everbody told me that BusyBox ain't an OS in a typical matter ;), I already knew that before. The point is why I still ask, because I'm not a BusyBox "guru" that I can say what programs and tools are available to know the full functionality. My intention is to hear, if there is maybe some kind of a workaround (e.g. a firewall applet) that fills these gaps that it takes to be called an OS.


When it's about to start a new Embedded Design it always comes in handy to know a few points about some OS. So that in a quick view, you could say that (here) BusyBox is fully sufficient for our needs and saves us a lot of money because we nearly don't need any storage, as it would take just because you use a full OS - That's what I meant in the beginning, that maybe these information could be a little bit more extended (e.g. with some of my questions).


Kind Regards


Frank
