2. Write the following ethreal trace to the text file using fprintf library function.
3. Finally, open the terminal and run either grep or wc command using the test.txt and answer the following question:
- Which ip address occurs most frequently in that test.txt file? How did you find it?
- Which protocol occurs most frequently in that test.txt file? How did you find it?
Please attach the screenshots of your code and explanations of the above 1,2,3 questions
