Dowloading a File from FTP Server to a local Server where User Id's are different

Hi,

The Setup is like this. I'm connecting to Unix machine from my local machine. After connecting to Unix M/c, i need to connect FTP server. Am successful in connecting to FTP server, but am not able to download the file from the ftp server to my local machine. I have different user id's and passwords for Unix machine and FTP server. Can any one please guide me through this.

Thanks in Anticipation.
