> A Java app that uses FTPClient to download a file from a website to Windows XP 
> works properly. But, when the same app runs on Linux to download the same file 
> from the same website, it hangs at listFiles().
> Using Java 1.5.0_03 on both the Windows XP and Linux. The version of Linux 
> used is Fedor Red Hat Linux Core 3 with all the latest updates. The following 
> segment of code from the program demonstrates the problem:
>               FTPClient ftp = new FTPClient();
>               ftp.connect(host);
>               reply = ftp.getReplyCode();
>               if (!FTPReply.isPositiveCompletion(reply)) {
>                 final String ftpStatus = ftp.getReplyString();
>                 ftp.disconnect();
>                 throw new IOException(
>                     "FTP server refused connection. Status: " +
>                    ftpStatus);
>               }
>               ftp.login(user, password);
>               reply = ftp.getReplyCode();
>               if (!FTPReply.isPositiveCompletion(reply)) {
>                 final String ftpStatus = ftp.getReplyString();
>                 ftp.disconnect();
>                 throw new IOException(
>                     "FTP server refused username/password. Status: " +
>                    ftpStatus);
>               }
>               String[] list = ftp.listNames();
