I've setup a sensor for counting files in a specific folder. But constant receiving the following alarm:

227 Entering Passive Mode

Below the logs:

There is another version of the sensor that has not been implemented yet. Stay tuned, I will send it to you manually so you can use it as a custom sensor.

Kind regards,

Thnx for the mail. Tried the following:

-u="<user>" -p="<pass>" -f="<folder>" -pasv -h="<server>" -id="2246"

which is resulting in the following error: 227 Entering Passive Mode (<server> )..

Which sensor type did you use as "vehicle" for the executable? Exe/Script or Exe/Script Advanced? What output do you get when running the executable with parameters in a command prompt window?

Using Exe / Script as the vehicle

The remote server returned an error: 227 entering passive Mode (server-ip)

This could be an issue due to a firewall. Is there a firewall between PRTG and the FTP? Further "candidates" might be the firewall running on the PRTG server (or Remote Probe) and the FTP itself, try disabling those local firewalls to see if it works then and check the logs of firewalls in-between. "227 entering passive mode" is basically ok, but then it seems to just sit there not being able to proceed and a firewall might be a possible reason for this.

Kind regards,

Erhard
