TCP/IP Protocols in networking

The purpose of this tutorial is to train system administrators how to solve complicated server networking issues using standard libpcap and networking tools. The course breaks troubleshooting into 4 categories based on protocol: ethernet, IP, TCP, and application. For each category, the instructor will describe the important components of the protocol, how to use tools to monitor for errors, how to correlate the output from the tools, and the corrective actions that need to be taken. All teaching examples are in the form of case studies based off of production experiences. Example tools include tcpdump, tethereal, Wireshark, netstat, arp, route and ifconfig. Example case studies include troubleshooting arp, IP routing, TCP states, DNS, DHCP, and SMB/NFS. This tutorial provides a detailed whitepaper in addition to the presentation slides.

Attendees will learn how to apply a troubleshooting methodology using the correct tools to locate problems a server has communicating on a network. The attendee will then be able to identify the faulty component and apply the appropriate fix
