Using proxy server

Hi,

I am using the proxy to connect to the server. I use the initSOCKS and initSOCKSAuthentication for proxy and then ftpClient.login. The server authenticates the user but then I get the following error. But If I comment out the proxy authentication I can download the files by ftp.
Please can someone suggest where i am going wrong?

If you can download without using proxy auth, why put it in?

Hi,

First of all, thanks much for replying back. Actually I am doing some test functionality now...but in the final version there will be a proxy between me and the server...so I am doing the simulation.

What I dont get is that the login works fine...but then when I do to download it fails....Can you suggest what can be the possiblities??? I think there is a problem between the Proxy and server connection....

Thanks

You could try PASV mode instead of active (if you are using active).

Try doing the same thing using a command-line client
