THREADS in C PROGRAM HELP PLEASE!! Using the thread3.c program provided below, itt will require some code modification. Those modifications include: - instead of 10,000 threads, create 40,000 threads in total - instead of creating just one kind of thread, create 4 kinds of threads (each with 10,000 instances) o group 1: adds 1 to counter o group 2: adds 5 to counter o group 3: subtracts 2 from counter o group 4: subtracts 10 from counter Run the program 5 times and take a screen shot showing the output of the run. Add comments throughout the code please! thread3.c given code: // Compile with://// clang -lpthread thread3.c -o thread3// or// gcc -lpthread thread3.c -o thread3//#include <stdio.h>#include <stdlib.h>#include <pthread.h> #define NTHREADS 10000 // shared variableint counter = 0; // thread to be executed - unspecified variable argumentsvoid *thread (void *vargp) {counter = counter +1;return NULL;} int main() {// array to keep Pthread IDs of created…

Brute Attack on FTP server (KALI -LINUX)   The file you downloaded contains the 100 most common passwords. Load the file in the Metasploit framework by setting the PASS_FILE variable. When you run the command, after some time, you will see a connection error and it says ‘scan complete’ but in reality, it is not. Why do you think that the first few scans went unsuccessful and then the connection error appears? Verify your answer using a log file generated at the victim’s machine. Furthermore, explain how you can circumvent this problem and show at least one working solution.   Upload the log file generated at the victim's machine which shows the first few scans went unsuccessful and then the connection error appears.   Also, include your answer and explain how you can avoid this problem.
