I want to transfer a file to a ftp server wich use explicite TLS/SSL.
When I connect with File Zilla and choose as servertype: FTPES - FTP over
explicite TLS/SSL i can connect and upload files.
I try to upload some files to a ftp server with explicite TLS.
My code work until the it upload the files. It throws an IOException.
The last response from the server (getReplyStrings()) is
[150 Accepted data connection]
In the upload folder it generates a empty file. I have no access to the FTP
log on the server.
FTPSClient ftp = new FTPSClient("TLS",false);
ftp.setTrustManager(TrustManagerUtils.getAcceptAllTrustManager());
KeyManagerFactory kmf = null;
try {
kmf =
KeyManagerFactory.getInstance(KeyManagerFactory.getDefaultAlgorithm());
kmf.init(null, null);
KeyManager km = kmf.getKeyManagers()[0];
ftp.setKeyManager(km);
} catch (NoSuchAlgorithmException e) {
e.printStackTrace();
} catch (UnrecoverableKeyException e) {
e.printStackTrace();
} catch (KeyStoreException e) {
e.printStackTrace();
}
ftp.setBufferSize(1024 * 1024);
ftp.setConnectTimeout(100000);
try {
ftp.connect("domain.com");
ftp.setSoTimeout(1000000);
if (ftp.login("login", "passsword")) {
ftp.execPBSZ(0);
ftp.execPROT("P");
ftp.changeWorkingDirectory("/");
if (ftp.getReplyString().contains("250")) {
ftp.setFileType(FTP.BINARY_FILE_TYPE);
ftp.enterLocalPassiveMode();
BufferedInputStream buffIn;
for(File file : files) {
Log.d("DEBUG","Uploading: " + file.getPath());
buffIn = new BufferedInputStream(new
FileInputStream(file.getAbsolutePath()));
boolean result = ftp.storeFile(file.getName(), buffIn);
buffIn.close();
}
}
ftp.logout();
}
ftp.disconnect();
} catch (IOException e) {
System.out.println(Arrays.toString(ftp.getReplyStrings()));
System.out.println(e);
Log.d("DEBUG", Arrays.toString(e.getStackTrace()));
}
This are the last lines from logcat:
