Tcpdump is a valuable network utility that can be used for troubleshooting and debugging. This article demystifies tcpdump - examining its options, as well as a real-world use case, for debugging networking issues in your Linux environment. 


If there were one network utility that I wish had been demystified for me as a support engineer, it is the tcpdump tool.
