Basic command line networking |
| Written by Michael D | |
In this tutorial I will focus on the main built-in networking applications that you can find in any distribution of Microsoft Windows 2000. I used them on a Windows 2000 SP4, but it's quite the same in all versions.
1) Netstat.exe
As the name implies, netstat.exe gives you the current status of your network connections. Typed without any parameters, it will show the active connections like shown bellow ("mihaidobos" is the hostname of my computer). Note that you can see here information on all open connections, their protocol, ports, hosts and state. The state parameters like "established" or "time wait" are explained in the Transmission Control Protocol Tutorial. The most important parameters of this command are netstat.exe /a - that will show all connections, netstat.exe /e that will show Ethernet connection(s) statistics and netstat.exe /s that will show per-protocol statistics. Please note that there are other parameters not so useful. A complete list and description can be seen by typing netstat.exe /? . Keep in mind that this can be done for any command (command.exe /? will show all options).
2) Ipconfig.exe
Probably the most useful command provided by Microsoft, Ipconfig.exe is used to check the network settings or repair a connection. The most used option is /all. Bellow you can see a ipconfig.exe /all example; I added an effect to the private content of the shot since it's not really the objective of this tutorial to tell you my MAC address or IP. If using a DHCP connection (this concept will be covered in another tutorial) you can release your IP address by typing ipconfig.exe /release or renew it by typing ipconfig.exe /renew. Also some useful commands are the /displaydns option which will show you the Domain Name Service (DNS) names cached in your PC's memory and ipconfig.exe /flushdns which will empty this cache. This can get pretty handy if you start getting "Could not resolve hostname" errors and you don't know why. 3) Nslookup.exe This command is used to resolve a hostname to an IP. The syntax is nslookup.exe <domain>. Eg : C:\>nslookup Google.jp Non-authoritative answer: Name: Google.jp Addresses: 66.102.7.104, 72.14.203.104, 72.14.235.104 4) Net.exe This command is used usually to access and maintain a Microsoft File/Printer Sharing environment, or to send text using Windows Messaging Service. The syntax is net.exe <command> <options>. You can see a screenshot bellow:  For other troubleshooting commands, please read the Command-line network diagnose tutorial.
