I'm using UBUNTU SERVER 20.04 in Oracle Cloud with VSFTP 3.0.3.
I can connetct to the FTP server ealisy using filezilla. I can navigate through ftp directories to upload and download files. But my Delphi 7 application (using IDFTP, indy component) can't connect to this ftp server.
Does anyone have any suggestions on how to proceed with this problem?
these are the delphi, linux and ftp settings.
Delphi 7 config
IdFTP1.Username := 'username';
IdFTP1.Password := 'password';
IdFTP1.Host := 'ip';
IdFTP1.Connect;
IdFTP1.Changedir(path);
IdFTP1.Put(line1, name1);
IdFTP1.Disconnect;
