TCP port check with timestamp to file

[Supporter]

Hi everyone,

people often ask how to write a permanent TCP port check over days with response time in a log file. This can be done very easily with PortCheck:

PortCheck.exe -t -st www.google.com 443 1000 c:\temp\logfile.txt

The logfile looks like this:

07/27/2024 09:46:10 AM - www.google.com - 142.250.74.196 - Port 443 - OPEN - 8ms

-t means "continuously" and -st writes the timestamp to each line (show time).
