5 basic commands for network troubleshooting


Network administrators must be able to monitor and resolve network disruptions. In fact, network administrators must be able to detect network problems before they occur. Network troubleshooting is a systematic process that is applied to solve problems on the network.
Here are 5 basic command prompt commands to detect and diagnose problems on the network.



1.Ipconfig
   Ipconfig is one of the internal commands in Command Prompt (CMD) that functions to view and     configure network device settings. The purpose of Ipconfig in the addition of the word / all is to         provide or display a connection configuration information, for example Host Name, Primary DNS       Type, Ethernet LAN Adapter.

2. Ping

    Ping is an abbreviation of Packet InterNet Groper, where ping is a utility used to verify whether a        network data packet is capable or not when the packet is distributed to an address without error.          The Ping utility is commonly used to check network errors. If Ping does not reach its destination        due to an error or because it is being blocked, the sending computer displays a timed out error              request or does not indicate the packet received.

3.Tracert
Tracert is a command to show the route the packet takes to reach its destination. This is done by sending an Internet Control Message Protocol (ICMP) Echo Request message to the destination with an increasingly Time to Live value. The route shown is a list of router interfaces (the closest to the host) contained in the path between the host and destination.

5. Netstat
Netstat is a text based program that functions to monitor network connections on a computer, be it a local network (LAN) or internet network. When do I need netstat? for example, when you are on the internet then suddenly the connection becomes very slow and you suspect there are programs on your computer that are the cause. If that is the case for you then you need to call the netstat program to check.
