How to monitor the number of network connections on a server.

I am troubleshooting a server problem and want to monitor the number of network connections. You need wc (wordcount) for Windows. The choice command gives me a three second delay.

Here is my script.

echo off
:loop
netstat -an | wc
choice /n /d n /t 3 >nul
goto loop

Here is the output. The first column should be the number of network connections on my server.

    234     903   15101
    296    1151   19199
    391    1531   25465
    494    1943   32271
    469    1843   30617
    391    1531   25465
    391    1531   25465
    545    2147   35629
    545    2147   35629

Quick Cisco 3845 IOS update

I have used several methods to update IOS but the easiest for me is old fashioned FTP.

Copy the image from an FTP server to the router.

copy ftp://user:pass@10.1.2.3 flash

Tell the router to boot form the new software image.

boot system flash c3845-advsecurityk9-mz.124-25a.bin
