Supress or Ignore Non-Trusted Certificate With FTPS.exe (MoveIT Freely)?

Question

One of the FTP accounts that I use recently began requiring secure FTP connections, which broke a script that I used to upload to it using a 'standard' FTP library. I've written a little batch file that will upload the 2 files via FTPS.exe (MoveIT Freely), but I get a dialog box that pops up and requires me to click yes.

Normally this wouldn't be a problem, but I'm calling the batch file at the end of a ~10 minute long script that parses, combines, and encodes several CSV files (usually unattended). With this dialog box popping up, I have to keep an eye on it... I'm trying to get this to the point where I can run it as a scheduled task and forget about it.

There doesn't seem to be much support for this freeware unless you are also a payware customer, so I was wondering if anyone else has run into this problem and knows a flag to ignore the error (or a workaround, or another free secure FTP solution). Error is below (server names changed).

MOVEit Freely

---------------------------
Non trusted certificate
---------------------------
The certificate's CN name does not match the passed value.

Certificate issued to: funftp501

Certificate issued by: Standalone007



Do you want to proceed with the connection?

Yes   No

Answer 1

If you are sure that you use the proper servername in your script (meaning: the exact name that the certificate was issued to), then you could try using the parameter '-natpasv'.

You can also use '-z' to skip warnings...

Hope this helps
