FTP Server using Apache FTPServer Library

Was working on getting a FTP Server. Creating a FTP server using Apache Library is very simple.
As you can see in the image you will need some libs, and all the libraries can be found here : http://mina.apache.org/ftpserver/apache-ftpserver-106-release.html
Below is the code to get started. You will also get all the properties file from the above link.


Content for log4j.properties.
log4j.rootLogger=DEBUG, C
log4j.appender.C=org.apache.log4j.ConsoleAppender
log4j.appender.C.layout=org.apache.log4j.PatternLayout
log4j.appender.C.layout.ConversionPattern=[%5p] %d [%X{userName}] [%X{remoteIp}] %m%n



Content for users.properties.
# Password is "admin"
ftpserver.user.admin.userpassword=21232F297A57A5A743894A0E4A801FC3
ftpserver.user.admin.homedirectory=f\:/
ftpserver.user.admin.enableflag=true
ftpserver.user.admin.writepermission=true
ftpserver.user.admin.maxloginnumber=0
ftpserver.user.admin.maxloginperip=0
ftpserver.user.admin.idletime=0
ftpserver.user.admin.uploadrate=0
ftpserver.user.admin.downloadrate=0
ftpserver.user.anonymous.userpassword=
ftpserver.user.anonymous.homedirectory=f\:/
ftpserver.user.anonymous.enableflag=true
ftpserver.user.anonymous.writepermission=false
ftpserver.user.anonymous.maxloginnumber=20
ftpserver.user.anonymous.maxloginperip=2
ftpserver.user.anonymous.idletime=300
ftpserver.user.anonymous.uploadrate=4800
ftpserver.user.anonymous.downloadrate=4800



Code below – can be found in the FTPServer Source Examples – Modified a little for my need.
package com.ftp.server;
import java.io.File;
import org.apache.ftpserver.FtpServer;
import org.apache.ftpserver.FtpServerFactory;
import org.apache.ftpserver.ftplet.User;
import org.apache.ftpserver.ftplet.UserManager;
import org.apache.ftpserver.listener.ListenerFactory;
import org.apache.ftpserver.main.AddUser;
import org.apache.ftpserver.ssl.SslConfigurationFactory;
import org.apache.ftpserver.usermanager.ClearTextPasswordEncryptor;
import org.apache.ftpserver.usermanager.PropertiesUserManagerFactory;
import org.apache.ftpserver.usermanager.SaltedPasswordEncryptor;
import org.apache.ftpserver.usermanager.UserFactory;
import org.apache.ftpserver.usermanager.impl.BaseUser;
import org.apache.log4j.PropertyConfigurator;
import org.slf4j.impl.Log4jLoggerFactory;
public class EmbeddingFtpServer { public static void main(String[] args) throws Exception {

PropertyConfigurator.configure("log4j.properties");

FtpServerFactory serverFactory = new FtpServerFactory();
ListenerFactory factory = new ListenerFactory();

// set the port of the listener
factory.setPort(8080);

// replace the default listener
serverFactory.addListener("default", factory.createListener());

System.out.println("Adding Users Now");
PropertiesUserManagerFactory userManagerFactory = new PropertiesUserManagerFactory();
userManagerFactory.setFile(new File("users.properties"));

userManagerFactory.setPasswordEncryptor(new SaltedPasswordEncryptor());
UserManager userManagement = userManagerFactory.createUserManager();
UserFactory userFact = new UserFactory();
userFact.setName("ahmed");
userFact.setPassword("ahmed");
userFact.setHomeDirectory("F:/");
User user = userFact.createUser();
userManagement.save(user);

serverFactory.setUserManager(userManagement);
serverFactory.setUserManager(userManagerFactory.createUserManager());

// start the server
FtpServer server = serverFactory.createServer();

System.out.println("Server Starting" + factory.getPort());
server.start();
}
}

Once done ,server will be running on port 8080 (factory.setPort(8080);) and “F:/” (userFact.setHomeDirectory("F:/");) directory will be the root Directory. Connect to server using any FTPClient like Filezilla.
NOTE: SSL part is not working, will updated once done.
