Monitoring Internet Activity for Windows and macOS
Monitoring your computer’s Internet activity is a powerful tool, enabling you to:
- keep an eye on background processes
- reveal viruses and other malware
- expose unauthorized access
- monitor running programs
- log process activity
..and much more. The best part? It’s super-easy. Here’s how I do it on Win XP:
- Open the command prompt and type “
netstat -n 5 > scan.txt
” - After a minute or two (or any amount of time), press
Ctrl+C
to stop monitoring - Type “
scan.txt
” to open the log file and check the results
There are many ways to modify the log output using various parameters. Here are a couple of alternate commands you can try:
netstat -b 5 > scan.txt
netstat -nao 5 > scan.txt
The second command provides PID numbers that may be verified against running processes in the Windows Task Manager (under View
>
Select
Column..
). Feel free to terminate any processes running unwanted TCP connections. For a complete list of netstat parameters, type “netstat help” in the command prompt.
Here’s how I do it on Mac OSX:
- Open Terminal and type “
netstat -b >> scan.txt
” - After a minute or two (or any amount of time), press
Ctrl+C
to stop monitoring - Type “
more scan.txt
” to open the log file and check the results
Happy Monitoring!

Thanks for sharing Jeff. Being one as well who works cross-platform, well let’s just say the information you provide here is an invaluable tool.
Is there anyway to include a timestamp in the logs?
