Network Troubleshooting TOOLS, Are a Necessity For Every Network Administrator

 PING Commend

• The most commonly used network tool is the ping utility this utility is used to provide a basic connectivity test between the requesting host and a destination host. This is done by using the Internet Control-Message Protocol (I.C.M.P) , which has the ability to send an echo packet to a destination host and a mechanism to listen for a response from this host. Simply stated if the requesting host receives a response from the destination host this host is reachable, this utilities is commonly used to provide a basic pictures of where a specific networking problem may exist for example, "if an Internet connection is down at an offices.The ping utilities can be used to figures out whether the problems exists within the office or within the network of the Internet provider."

Route

The last of the Tools covered in this article is the Route Utility, this Utility is used to display the current status of the Routing Table on a Host.
