QUICKLY AND SIMPLY TROUBLESHOOT NETWORKS FROM THE COMMAND LINE

I love using command line tools, especially for troubleshooting networking. There are two simple commands you need to know;ipconfig and ping.





 Here’s a simple guide to finding where the problem :

• Open the command line by opening the “run” dialog box, entering cmd and clicking OK
• Ensure that the TCP/IP service is running by pinging the loopback address like so: ping 128.0.0.1
• Run the ipconfig command, which should give you information something like this:
IP Address. . . . . . . . . . . . : 192.168.1.100
Subnet Mask . . . . . . . . . . . : 255.255.255.0
Default Gateway . . . . . . . . . : 192.168.1.1
• If your address is not an APIPA address, ping your IP-address.
• Ping the default gateway
• Ping www.iana.org
• Ping the website or server you are trying to reach

 

If any of the above tests fail, you’ve found where the problem is.
