Mike, have you run curl against upload against a Glub server running GlubTech FTP Wrapper 3.0.3. The target server I'm running against "appears" to be running 3.0.3. and I'm still a
having problems during the dataport handshake.

Just trying to see if others with the same issue are successfull.

The reason I said "appears" because the log file that shows the new GlubTech FTP Wrapper 3.0.3 was created July 21 at 13:53, the same day the version was released.

I raised this in the forums, and the tech support was very professionally handled. I'm not a customer, but they accepted that it was their problem with no argument, and deserve some credit for that.

That is correct, but it might be nice to also be able to circumvent this sort of error in future.

I was looking to see if there is a wway to allow curl to make the order of sending the TYPE call, so it can be before the PASV rather than after. I'm not sure which is correct, or if both are valid - apparently many other client implimentations work the other way. Thread is at:
