Thread: Password hacking by bruteforce?

-

hi,
think easy hack passwords in linux, did not try yet. if use sudo 3 attempts correct password. if enough time should no problem hack bruteforce. imagine script attacker places on machine runs few hours or days.

think more effective delete user out of admin (or adm?) group user cannot danger anymore. have login root , readd user then.

say: if login root got same effect sudo. of course same. why use system (not sure yet) create sub enviroments of os, got attribute can run without root, got 1 account can sudo , once sudo access denied there no other way login root. can repermit sudo access parent os layer.

maybe virtual server that. or maybe kind of rootjail.

think?

i think if use 8 letter/symbol password, that's,

26+26+10+12 = 74

74^8 = 899194740203776 possible passwords.

@ 3 seconds each (the default time between allowed tries) thats,

85539834 years of trying. if hit right password @ 50% through,

that's still 45 million years. paraphrase clint eastwood, "go ahead, brute force me".

, hope don't have 9+ letter password.

no need other weirdness. if sitting @ machine have root access anyway. encrypted home protection that.

i'm struggling dht11 sensor work on arduino. code compiles without problems in serial monitor output keep on getting " read sensor: time out error" i've tried multiple libraries, adafruit etc still none of them worked. set serial monitor same speed (115200) didn't fix problem.  i'm using:  mega2560  dht11 temp+hum sensor windows10 x64 arduino 1.6.9 library dht11.h v0.4.1 source:  http://playground.arduino.cc/main/dht11lib wiring : blue = gnd yellow = 2 red = 5v (also see picture)  my code:    code: [select] #include <dht11.h> // //   file:  dht11_test1.pde // purpose: dht11 library test sketch arduino // //celsius fahrenheit conversion double fahrenheit(double celsius) {   return 1.8 * celsius + 32; } // fast integer version rounding //int celcius2fahrenheit(int celcius) //{ //  return (celsius * 18 + 5)/10 + 32; //} //celsius kelvin conversion double kelvin(double celsius) {   return ...

Arduino Uno + KTY81/210 temperature sensor

hi, sorry, new , unsure lot of things, need clarification. haven't found information explains how , why things work, "do this, that" i following guide ( arduino-thermistor-temperature-sensor-tutorial ) connect thermistor arduino uno. here temperature sensor information: temp. sensor 2000r +-1% to92 part.no.:   kty81-210 name:   temp. sensor 2000r +-1% to92 description:   2.5mm, 1980...2020ohm, -55...+150°c and here sensor's data-sheet: sensor data-sheet i have connected same way in guide. works , values being serial printed. what don't understand: 1. thermistor's , resistor's ohm value should equal, correct? in case 2000 ohm? 2. thermistor has ptc, i'm guessing have invert math or use ntc thermistor instead correct values? (currently resistance goes temperature goes down) 3. understand code uses steinhart-hart math logic convert resistor value temperature value, need a, b , c coefficients of thermis...
