}i need to upload files to a server and to make it resumeable i need to user raw commands and REST.
Im using QFtp raw command STOR and when it returns code 227 i parse the data and get the ip and open port then when i recieve code 150 i open a tcp port as a data socket to send the data but after a few seconds it returns the error "Data channel timed out.\r\n Win32 error: The network connection was aborted by the local system." what am i doing wrong here?how am i supposed to use this command?
CodePudding user response：
so i was reading about it and somewhere said that using PASV isnt smart and instead use EPSV to open a port.i changed my code like this and parsed the new port and changed user permissions of local ftp server to all users and it worked!
myfile=new QFile(location);

QFileInfo fileinfo(myfile->fileName());
qInfo()<<"size: "<<fileinfo.size();
qInfo()<<"name: "<<fileinfo.fileName();
qInfo()<<"uploading : "<<location;
qInfo()<<"file name is:"<<myfile->fileName();
ftp.rawCommand("REST 1000");
ftp.rawCommand("PWD");
QString text="STOR " fileinfo.fileName();
qInfo()<<text;
ftp.rawCommand(text);
