Guys, Please, tell me - if it possible to learn smth new or to get any experience if box is reset every fu…ing 3 minute? Why are you doing so? Maybe if smth goes wrong its not the way out to reset and to start it from the beginning? May be its time to sit and to think a bit what am i doing wrong? It’s a kind of mess - trying to get fu…ing low-level shell when ping is lost, box is reset, etc…
P.S. Sorry for emotions - a bit tired of this.
