Connection closed without indication ошибка ftp

everyone,I am suffering this problem for 4 days..Help is needed…

I am developing an android program that intends to upload a file to a FTP server.

My developing environment: ubuntu12.04 + eclipse

I want to upload the file in a service. Now, the service can be started successfully.
here is the code of the upload method in service class.

public String ftpUpload(String url, String port, String username,String password, 
        String remotePath, String filePath,String fileName) {       
    FTPClient ftpClient = new FTPClient();      
    FileInputStream fis = null;  
    String returnMessage = "0";  
    try{
        System.out.println("我看你能不能连接上！！！！");
        ftpClient.connect(url,21);        
        System.out.println("我草还真能连上！！！！！！");
        int reply = ftpClient.getReplyCode();
        if(!FTPReply.isPositiveCompletion(reply)){              
            ftpClient.disconnect();
            System.err.println("FTP server refused connection.");
            System.exit(1);
        }
        boolean loginResult = ftpClient.login(username, password);  
        int returnCode = ftpClient.getReplyCode(); 
        Log.v("returnCode",""+returnCode);
        System.out.println(loginResult);
        if(loginResult && FTPReply.isPositiveCompletion(returnCode)){               
            ftpClient.listFiles("");
            ftpClient.makeDirectory(remotePath);  
            ftpClient.setFileType(FTP.BINARY_FILE_TYPE);
            ftpClient.changeWorkingDirectory(remotePath);  
            ftpClient.setBufferSize(1024);  
            ftpClient.setControlEncoding("UTF-8");                    
            fis = new FileInputStream(filePath+"/"+fileName);  
            ftpClient.enterLocalPassiveMode(); 
            System.out.println("last step!!!!!!");
            ftpClient.storeFile("IwantYou", fis);                  
            returnMessage = "1";         
        } 
        else 
            returnMessage = "0";                      
    }
    catch (IOException e){              
        e.printStackTrace();  
        throw new RuntimeException("擦，还真没连上！！！",e);  
    } 
    finally{            
        try{                
            ftpClient.disconnect();  
        } 
        catch(IOException e){               
            e.printStackTrace();  
            throw new RuntimeException("关闭FTP连接发生异常！", e);  
        }  
     }  
     return returnMessage;  
}

here is the problems:

test on android device: successful

test on emulator

if the emulator and the FTP server are not in the same computer:successful
if the emulator and the FTP server are in the same computer: fail

so let’s focus on this case..and some different options happens

if I connect real IP address(10.238.154.173) exception happens at
connect method, here is the logcat:

if I connect the IP(10.0.2.2) I can connect successful.but the
storefile method failed.

I have google it for several days, all failed.

Any suggestion could be appreciated! Thanks!

org.apache.commons.net.ftp.FTPConnectionClosedException: Connection closed without indication.

Please follow the issue template and provide more details. issues like this do not provide any way of replicating the problem and spotting if it’s an Apache Commons FTP bug or an Android Upload Service bug. Thank you!

English is poor, please forgive me。

Using FTP to upload files to the window server was correct yesterday, but it went wrong today. The device system is android4.4.4

Sorry, but you have to follow what is in the issue template and provide necessary details, otherwise I couldn’t help you in any way

The same file, second pass will make mistakes ,and return «Error while uploading: xx to xx»
I don’t understand the code

try {
    String remoteFileName = getRemoteFileName(file);
    if (!ftpClient.storeFile(remoteFileName, localStream)) {
        throw new IOException("Error while uploading: " + file.getName(service)
                              + " to: " + file.getProperty(PARAM_REMOTE_PATH));
    }
    setPermission(remoteFileName, file.getProperty(PARAM_PERMISSIONS));
} finally {
    localStream.close();
}

The exception is thrown because the transfer of the file to your FTP directory is not possible. I don’t have the Apache Commons Net FTP docs at hand, but this may be due to permission policy for your FTP user or if the file already exists, in which case it doesn’t get overwritten.

Can you successfully upload the file for the first time? If I understand correctly, you get the exception only the second time you try to upload it.

Successfully upload the file for the first time.But,Some FTP servers can upload second times。
I’ll see if the FTP service is insufficient。
Example：
new FTPUploadRequest(mContext, _ip, _port)
.setUsernameAndPassword(_accout, _pwd)
.addFileToUpload(path, to)
.setNotificationConfig(config)
.setCreatedDirectoriesPermissions(new UnixPermissions(«777»))
.setSocketTimeout(301000)
.setConnectTimeout(301000)

Here it’s storeFile method JavaDoc. The method should overwrite the existing file the second time you try to make an upload.

The best way to check if the problem is in the library or in your FTP server config is to use one of the test FTP servers

You are right，this is FTP server Permission denied。
thanks

Я сделал небольшое приложение для Android, свое первое. Одна из его функций — загрузка текстовых отчетов на ftp-сервер. Я использую apache-commons-net. На некоторых устройствах ftp сервер закрывает соединение без индикации. Журналы сервера пусты.
Ниже приведен код внутреннего класса, выполняющего передачу файлов. Необходимо отправить четыре файла, отсюда и цикл. Элемент управления textViewResult используется для информирования пользователя о статусе передачи.
1. Видите ли вы, возможно, некоторые очевидные проблемы с кодом, которые могут привести к закрытому соединению?
2. Ошибка «соединение закрыто без индикации» ничего не говорит мне о реальном источнике проблемы. Есть ли способ получить более подробную информацию об ошибке?

Edit: Проблема была обнаружена на LG G5, H831, android 7.0. На LG H635 Android 6.0 работает без проблем.

В данном случае исключение говорит о том, что порт, по которому подключается клиент, никто не слушает. Попробуйте явно задать порт.

Все из-за невнимательности — проблема оказалась как раз в фтп сервере. Извиняюсь за беспокойство.
Вопрос решен. Спасибо за помощь.

RA FTP job fails with error «Connection closed without indication»

Issue/Introduction

Error Message :
com.uc4.ftpjob.DataTransferException: Connection exception.

Currently thread management with a wild card file transfer (FT) is implemented in a way that the FT terminates if one of the threads throws an exception. The Java standard thread pool is used.

Transferring multiple files in multiple threads uses the java.util.concurrent.ThreadPoolExecutor class. If the limit of connections is reached, there is a exception in one thread, that causes the whole ThreadPoolExecutor fail, the filetransfer stops with error:

com.uc4.ftpjob.DataTransferException: Connection exception.

The FTP Agent currently does not support to react on a connection failure within one single thread.
The implementation uses the «java.util.concurrent.ThreadPoolExecutor» class.

Reaching the limitation of concurrent connection on server side causes an exception in one of the threads which causes the whole TheradPoolExecutor to fail.
Current behavior is that Agent cannot reliably handle connection limitation on server side. This feature is not implemented.

Environment

OS Version: N/A

Cause

Cause type:
By design
Root Cause: The FTP Agent currently does not support to react on a connection failure within one single thread.

Resolution

The FTP Agent currently does not support to react on a connection failure within one single thread.

Fix Status: No Fix

Additional Information

Workaround :
The workaround is to work with a minimum set on threads. In every case lower than the server has configured taking into consideration that the server might have established connections from another client than the Agent.

Don’t think it’s from FileZilla.

Please read Logs and post a log from FileZilla here. Do not modify anything (except username and password, if any).
