netstat to log file
Recently at work we ran into an issue of needing a script that would perform a netstat and dump it to a log file. We were recording UDP sessions and ended up with the following script:
code:
@echo off
:START
echo %date% - %time%%»c:\netstatlog.txt
netstat -ano»c:\netstatlog.txt
timeout /T 60 /NOBREAK
GOTO START
This script is designed to output the date/time that it ran as well as the results of a “netstat -ano” to a log file. Additionally, after it has returned those results, it then has a 1 minute timeout before returning to the beginning and running again. This was setup to run indefinitely OR until will turned it off.
There are numerous tweaks you can perform to this script, such as various netstat options as well as tweaking the timeouts to increase or decrease it.
Some other options we used were to include the tasklist feature to print the .exe’s that were using the ports. This can be accomplished two ways actually. The simplest is to change the “netstat -ano” to “netstat -anob”. This is a nice way to do it as it will keep all that data together in one dump. However if you’d like additional details (such as how much ram each service is using) you can use the tasklist option.
After the netstat line, add the following:
tasklist»c:\netstatlog.txt
This will output the tasklist in the standard form. Typing “tasklist /?” in a cmd prompt will show you the additional switches you can use (such as “/V” for verbose mode).
Hope that this article helps someone else out with any scripting needs for the netstat tool. There is soo much more that can be added to this and I’m sure I will be posting further details and edits to it.
Happy Geeking!

Rebirth.
So I started my Tumblr many months ago, made a single post and then forgot about it. Kept meaning to get back into it and I have on numerous occasions praised the functionality of tumblr over say twitter or even FB, but have yet to get back on this…
Well, I’m gonna try :)
So to begin, my next post will be some scripts that I’ve built for various networking scenarios at my office. Nothing special fancy or proprietary, just standard batch scripting. :)
Here’s the all the luck I’m gonna need to keep this going :)
