Troubleshooting TCP/IP Networks (Wireshark University)


In this official Wireshark University lab-based course, you will discover effective Wireshark operations and packet-level TCP/IP communications by examining both properly and poorly performing networks. Spend half your class time learning the features of Wireshark, the world’s most popular analyzer. After that, you’ll focus on reviewing both the normal and abnormal communication patterns of the TCP/IP suite and most common applications, including DHCP, DNS, FTP, Telnet, HTTP, POP, and SMTP. With a strong emphasis on hands-on lab exercises and real-world case studies in this course, you’ll gain skills that can be used immediately following the class.
