I have a client device connecting to the DriveHQ ftp server to upload files, the client is able to connect and login succesfully but after this i get a Sytax error(501) response from the server. I used wireshark to find out what happened and found out it's a response to the STRU F command from the client, baslically this is what happens:
>>> USER ctbvFTP
>>> PASS *****
>>> TYPE A
>>> STRU F
I know STRU F is an older Telnet command and i prefer not to use it but i'm not able to use another client type in this case.
Is there any way to fix this, or is the command not supported by the server?
