I am trying to implement an FTP server in my application using the Apache FTP server library.
The server is up and running and working fine, but only once.
Note: I am using a hardcoded user for now. username: test and password: test
So in order:
App is launched, server is started, lets all FTP clients login.
App is killed by user.
App is started by user and server is started. Replies
530 authentication failedto user logging in withusername: testandpassword: test
After that it responds with 530 authentication failed
My code below for making the server:
public void makePropertiesFile(){
File file = new File(Environment.getExternalStorageDirectory().getAbsolutePath()+"/Download/user.properties");
if(file.exists() == false){
try {
file.createNewFile();
logMessage("user.properties File did not exist, made one");
properties = file;
this.addUsers();
} catch (IOException e) {
e.printStackTrace();
}
}
else {
logMessage("File already exists, no need to recreate");
userManagerFactory = new PropertiesUserManagerFactory();
userManagerFactory.setFile(properties);
userManagerFactory.setPasswordEncryptor(new SaltedPasswordEncryptor());
org.apache.ftpserver.ftplet.UserManager userManager = userManagerFactory.createUserManager();
serverFactory.setUserManager(userManager);
}
}
public void addUsers(){
userManagerFactory = new PropertiesUserManagerFactory();
userManagerFactory.setFile(properties);
userManagerFactory.setPasswordEncryptor(new SaltedPasswordEncryptor());
baseUser = new BaseUser();
baseUser.setName("test");
baseUser.setPassword("test");
baseUser.setHomeDirectory(Environment.getExternalStorageDirectory().getAbsolutePath());
baseUser.setEnabled(true);
List<Authority> authorities = new ArrayList<Authority>();
authorities.add(new WritePermission());
baseUser.setAuthorities(authorities);
org.apache.ftpserver.ftplet.UserManager userManager = userManagerFactory.createUserManager();
try {
userManager.save(baseUser);
} catch (FtpException e) {
e.printStackTrace();
logMessage("Could not save User");
}
serverFactory.setUserManager(userManager);
}
public void start(){
serverFactory = new FtpServerFactory();
listenerFactory = new ListenerFactory();
listenerFactory.setPort(port);
serverFactory.addListener("default",listenerFactory.createListener());
ftpServer = serverFactory.createServer();
this.makePropertiesFile();
try {
ftpServer.start();
logMessage("Started FTP server on port: " + port);
} catch (FtpException e) {
e.printStackTrace();
logMessage("Failed to start FTP server on port: " + port);
}
}
