i have tried create a project with library commons.net for send via ftp some files. But i created a connection with my server i have received this error.
org.apache.commons.net.MalformedServerReplyException: Could not parse response code.
Server Reply: SSH-2.0-OpenSSH_5.3
i have followed this article for create my connection, and with official examples i've controlled article.
my java code here:
private void connect(String host, String user, String pwd) {
try{
ftp = new FTPSClient(false);
//ftp.addProtocolCommandListener(new PrintCommandListener(new PrintWriter(System.out)));
int reply;
ftp.connect(host,22);//error is here
reply = ftp.getReplyCode();
if (!FTPReply.isPositiveCompletion(reply)) {
ftp.disconnect();
throw new Exception("Exception in connecting to FTP Server");
}
ftp.login(user, pwd);
ftp.setFileType(FTP.BINARY_FILE_TYPE);
ftp.enterLocalPassiveMode();
}catch(Exception ex){
ex.printStackTrace();
}
}
I do not understand where I went wrong.
The FTPS protocol does not run over SSH. What you need is SFTP. For this you could look at the Jsch library
JSch jsch = new JSch();
Session session = jsch.getSession( user, host, port );
session.setConfig( "PreferredAuthentications", "password" );
session.setPassword( pass );
session.connect( FTP_TIMEOUT );
Channel channel = session.openChannel( "sftp" );
ChannelSftp sftp = ( ChannelSftp ) channel;
sftp.connect( FTP_TIMEOUT );
SFTP (file transfer running as an SSH stream over an SSH connection) is not the same as FTPS (FTP using SSL/TLS).
import com.jcraft.jsch.JSch;
import com.jcraft.jsch.Session;
public class FTPConnectAndLoginDemo {
public static void main(String[] args) throws Exception {
String user = "username";
String host = "hostadress";
int port = 22;
String pass = "password";
JSch jsch = new JSch();
Session session = jsch.getSession(user, host, port);
session.setConfig("StrictHostKeyChecking", "no");
session.setPassword(pass);
session.connect();
System.out.println("Connection established.");
System.out.println("Creating SFTP Channel.");
}
try this instead hope this can help.The Session.setConfig ommits the hashcode check and allows user to connect to host.
