Appendix B: Ping and TCP/IP Debugging Tools
Ping notes: If you want to ping another workstation or server and you do not know its DNS name or IP address use ipconfig (below). To learn all the ping command’s option, enter ping /?.
ipconfig
USE: Determine the IP address and other related information about a workstation. Enter ipconfig /? at the prompt to display the options possible with this command. The two most common entries: ipconfig and ipconfig/all.
EXAMPLES OF USE: You want to ping a remote server but you do not know its IP address. Go to the server and at the command line prompt enter “ipconfig.” The server's IP address will be displayed. Return to the earlier workstation and perform the ping test to this address.
tracert
USE: Determines how many router hops a packet took to reach its destination. This can help determine why a network is slow (or not functioning). Enter tracert /? at the prompt to display the options possible with this command.
EXAMPLES OF USE: I want to determine how many routers are between my system and my ISO. Enter tracet followed by the name or IP address of the destination system.
Netstat
USE: Displays the current status of all listening TCP/IP ports. A TCP/IP port is where applications connect to the server or workstation.
EXAMPLES OF USE: You would like to see how many applica- tions are tied to your system that use TCP/IP.
