             Summary: FTPSClient not using the Socks Proxy when opening passive data connection
                 Key: NET-637
                 URL: https://issues.apache.org/jira/browse/NET-637
             Project: Commons Net
          Issue Type: Bug
          Components: FTP
    Affects Versions: 3.6, 3.5
         Environment: Windows
            Reporter: Michael Seganti
            Priority: Minor


I'm routing FTPS traffic through a SOCKS proxy host.  I setup the proxy using: 

FTPSClient ftps = new FTPSClient("TLS", false);
InetSocketAddress sa = new InetSocketAddress(proxyHost,proxyPort);
Proxy proxy = new Proxy(Proxy.Type.SOCKS, sa);
System.out.println("Using Proxy Server: " + proxy);
ftps.setProxy(proxy);
...
ftps.enterLocalPassiveMode();
for (FTPFile f : ftps.listFiles()) {
	System.out.println(f.getRawListing());
}

When establishing the connection, the above code does go through the proxy and I'm able to login.  When I try to do anything, say listFiles, It does the SYST and then attempts to enter passive mode, but the connection times out:
227 Entering Passive Mode (123,45,678,9,11,243)
java.net.ConnectException: Connection timed out: connect

	at gov.nyc.ftputils.FTPConnection.listFiles(FTPConnection.java:1270)
	at gov.nyc.ftputils.FTPClientUtil.main(FTPClientUtil.java:572)

I then comment out the proxy code and added: 

System.getProperties().put( "socksProxyPort", proxyPort);
System.getProperties().put( "socksProxyHost" ,proxyHost);

And then I'm able to get the listing, get files, etc.

Adding -DsocksProxyHost=myproxy.host to the java command line also works.
