FTP Client Using Apache Common net library using Socks Proxy Server

August 2, 2012 1 comment

As we have the FTP Server code in previous post, here is a FTP Client using Apache Commons library.  Below is a basic code which we can use to connect to our FTP server which we created over a SOCKS Proxy Server. (Assuming you have a SOCKS proxy server running already – if not then code can be used just as a FTP Client to connect directly to FTP Server).

Below Image shows, libraries required and parameter passed from the build.xml (this can be done over the command line as well)

Below Image shows changes required to Route all Packets to go through Proxy Server

Libraries Required.

<path id="FtpClientDemo.classpath">
        <pathelement location="bin"/>
        <pathelement location="lib/commons-net-3.1-ftp.jar"/>
        <pathelement location="lib/commons-net-3.1.jar"/>
    </path>

Sample Arg in Build.xml File

<target name="FtpClientDemo">
    <java classname="com.ftp.client.FtpClient" failonerror="true" fork="yes">
        <jvmarg line="-Djava.net.preferIPv4Stack=true"/>
        <!-- Proxy Argument Below -->
        <!-- <arg line="-PrH 192.168.0.201:1080 -p true -b -s 192.168.0.100 sipl sipl LookAppCode.rar f:\LookAppCode.rar"/> -->
        <!-- Normal Connection to FTPServer without Proxy -->
        <arg line="-l 127.0.0.1:8080 ahmed ahmed"/>
        <classpath refid="FtpClientDemo.classpath"/>
    </java>
</target>

FTP Server using Apache FTPServer Library

August 2, 2012 5 comments

Was working on getting a FTP Server.

Creating a FTP server using Apache Library is very simple.

FTPServerCode

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.
