You have 8 balls, one is heavier than the other. You also have a scale that will compare the weight of two things put on it. How can you find the heavy ball with using the scale twice?

3 Answers

Break the balls into the following groups: (1,2,3),(4,5,6),(7,8) Step 1. Weigh (1,2,3) against (4,5,6) Two possible outcomes: The two groups are equally heavy. (Case A) One of these groups is heavier than the other. (Case B) Case A --> Weigh 7 against 8. Now you have identified the heavier ball in 2 weighing. Case B --> Take the heavier group (assume it to be (1,2,3)), take any two balls and weigh them against each other. Either one of these is heavier else the third ball is. Less

Explain how tcpdump works and what the outputs mean.

3 Answers

tcpdump command is also called as packet analyzer. tcpdump command will work on most flavors of unix operating system. tcpdump allows us to save the packets that are captured, so that we can use it for future analysis. The saved file can be viewed by the same tcpdump command. We can also use open source software like wireshark to read the tcpdump pcap files. Less

that was a very good answer.

That's a good answer. Now, I am going to give you a packet capture in a pcap file, and I want you to tell me why this particular web server is not working. You may use wireshark if you wish, but I would be more impressed if you could diagnose the problem using just tcpdump. Less
