How to FTP file using a proxy WITH JSCH libraries

I want to ftp files to a remote location and I am bound to use a proxy server for that. I was able to connect to the FTP location via following command :

sftp -o "ProxyCommand /usr/bin/nc -X connect -x <proxy_host>:<proxy_port> %h %p" username@ftp_server:


But I want to automate this process of file transfer and I am using Jsch for FTP and snippet of code is below:

String sourceFile = sourceDir + fileName;
JSch jsch = new JSch();
int port = Integer.parseInt(getFtpPort());
Session session = jsch.getSession(getUserName(), getHost(), port);
session.setConfig(STRICT_HOST_CHECKING, ANSWER);
session.setProxy(new ProxyHTTP(<proxy_host>, <proxy_port>));
session.setPassword(getPassword());
session.connect();
Channel channel = session.openChannel(FILE_PROTOCOL);
channel.connect();
sftpChannel = (ChannelSftp) channel;
sftpChannel.cd(desDir);
File fileToTransfer = new File(sourceFile);
sftpChannel.put(new FileInputStream(fileToTransfer), fileName);


With above code I am getting following exception:

Caused by: com.jcraft.jsch.JSchException: ProxyHTTP: java.io.IOException
at com.jcraft.jsch.ProxyHTTP.connect(ProxyHTTP.java:158)
at com.jcraft.jsch.Session.connect(Session.java:210)

This Worked for me

ProxyHTTP proxy = new ProxyHTTP("192.168.10.1",80)
proxy.setUserPasswd("username","password");
session.setProxy(proxy);


This worked for me.

JSch jsch = new JSch();
java.util.Properties config = new java.util.Properties();
Session session = jsch.getSession(RemoteUserName, RemoteIpAddr, RemotePortNo);
session.setPassword(RemotePassword);
config.put("StrictHostKeyChecking", "no");
session.setConfig(config);
session.setProxy(new ProxyHTTP(ProxyName, ProxyPort));
session.connect();


use
session.setProxy(new ProxySOCKS5(, ));

Instead of proxyHTTP,

hope it works for you...
