commons-net ftp with proxy

Hi,

I'm using the commons-net library (FTPClient) to do some ftping. However,
being stuck behind a big firewall is making it difficult to connect to
external servers. Having searched around I've discovered that you can use
the socks proxy settings:

      System.getProperties().put( "socksProxyPort", "XXXX");
      System.getProperties().put( "socksProxyHost" ,"XXXX");

      System.getProperties().put("java.net.socks.username", "XXXX");
      System.getProperties().put("java.net.socks.password", "XXXX");

However, having tried this, I'm now getting the following error when I try
to connect (  ftclient.connect(server)   ):

      java.net.SocketException: Reply from SOCKS server has bad version

I've also tried using the usual proxy settings, ie:

      System.getProperties().put( "http.proxyPort", "XXXX");
      System.getProperties().put( "http.proxyHost" ,"XXXX");
      System.getProperties().put( "http.proxyUser", "XXXX");
      System.getProperties().put( "http.proxyPassword" ,"XXXX");

which give me the following:

      java.net.ConnectException: Connection timed out: connect


Am I right in thinking that my proxy is not a SOCKS (4 or 5??) proxy and
this is why it's not working?

And does anyone know any way around this?


much appreciated.

Charles Jacobson

Hi,

I am stuck with a similar problem. I later found out that the proxy I
am behind is a FTP proxy over an HTTP tunnel.

One way to find that out is to try and open a ftp site in a browser
like IE and it shows a warning message like, "Your proxy allows only
read only access to the FTP location".

I am not very sure how to get through it, but still trying!

Regards,
Bindul
