    Re: netstat

    So are you any having connectivity issues. This are all the open ports in your computer and it is showing you all the active connection, what are the programs using the network resources and at which port.

    Re: netstat

    Hello doogles! As mentioned by Zachary, are you having any issues with your connection. Because as you might be knowing "netstat" just shows the network statistics displaying both incoming and outgoing network connections, routing tables, etc.

    Re: netstat

    netstat 5

    Running netstat with a number after the command will continue to run the command until stopped. In this case netstat would be refreshed ever five seconds. To cancel press CTRL + C.

    Notice: Keep in mind that if you have network applications open, such as the browser you're using to view this page, additional items will be listed when you run "netstat" and/or the "netstat -a" command. So you may see items from Computer Hope in your list; if you want a true listing of what is running in the background, close all programs and run the command.

    Re: netstat

    thanks guys for all your information on this, in clearer now how it all works, it seems that the server is slowing down , thought it might have something to do with network , my inetpub/mailroot/badmail folder is very unresponsive to look inside or to delete,

    Re: netstat

    Hello doogles! We can't help you with just the output of netstat command, we require some more information. If you are having some problem with some folders on server then please mention how you are connected with your server, how you are accessing the server and all that....

    Hope I was clearer to you!
