I have a PRTG port sensor that I'm using to make sure a particular port is open. It works fine.
I want to add the option to send a command and check the response. In a normal telnet window, I can enter the command and get a response back.
When I have the sensor send the same command, it gives a "read timed out" error. I have "write sensor result to disk" selected, and when I open the log file, I can see that the sensor received the expected response from the server. So why is the sensor giving me a timeout error?
