This chapter presents a number of tools that do not warrant a full chapter of their own. While these tools are not as complicated as the others listed in this book, they are the the tools most frequently used in network administration. When something goes awry, they will likely be the first tools you use, even if only to rule out certain problems before continuing with a more detailed examination. The tools listed here include the ping program, which performs basic tests for network reachability to a host; the telnet and Netcat programs, which allow you to test application level protocol problems; traceroute and MTR, which determine network routing paths; and netstat, which prints information about network connections to a workstation. |
