Unencrypted FTP not longer possible

Votes:

0

After upgrading to the latest version i'm not longer able to use unencrypted FTP. When i try to add a new FTP-Sensor there is no point "Don't use SSL (Basic FTP, recommended) : In most cases, you will use basic FTP without encryption.... " and the FTP-Server i'm monitoring is not offering encryption so i can't monitor it any longer.

ftp missing unencrypted

Hello,

I'm sorry for the inconvenience you're having with the reworked FTP sensor. When using "explicit Transport-Level-Security" with this sensor type, PRTG first tries to establish a secure connection to the FTP server. Only if the server rejects this connection, PRTG retries to reach the server via an insecure connection.

We've build this automatism to avoid unnecessary settings for the sensor.

To solve this issue, please reconfigure your FTP server to reject SSL connections altogether. It seems that your server currently only rejects the user after a secure connection has been established.

Hello,

Please use the "explicit Transport-Level Security" in the FTP Sensor settings. We will release a new version of the sensor in the near future which will use this setting by default.

Best regards

But this doesn't solve my problem as the destination is not supporting TLS, i need this to be done without encryption ! After switching to "explicit Transport-Level Security" in the FTP Sensor settings i got the message "User xxxx access denied. Use insecure access ".

Many thanks.

As this FTP-Server is hosted by an external company and used also from other customers they are not able to configure it in this way. Would it be possible to build an own sensor which uses unencrypted connections or would it be possible to have a second FTP-sensor from Paessler ? Many thanks.

Currently there are no plans to change the FTP sensor, I'm sorry. Of course you could write your own sensor which checks an FTP server and returns an OK or NOTOK. This could be done, for example, with a Windows command line script or an EXE file.

In PRTG you can use such an extension with the "EXE/Script Sensor" (see https://www.paessler.com/manuals/prtg/exe_script_sensor.htm).

For detailed information please see the API documentation https://www.paessler.com/manuals/prtg/application_programming_interface_api_definition
