Ftp using proxy RHEL 6.2

ETC Proxy Server
1

Hello all

I am connecting vendors ftp site to get the data using our proxy server.

  1. First I connect to my company's Proxy Server using ftp.
ftp myorg.proxy.server

After this command I am connecting to proxy. This does not ask me password.

  1. Now from Proxy I run another Ftp command.
ftp vendors.ftp.site.server

It asks me the password and input it and I get ftp prompt.

ftp>

Is there any way I can do all these in single command , or can I automate this. I tried but could
not get any proper answer for this case.

I also saw RHEL( RED HAT) FTP manual and found some entry of

Proxy ftp_commands

This seems is what I am trying to do but I do not know how to use this command.

I am not the admin but a user with limited access. I am on RHEL 6.2.
Can some one please help me out if possible or confirm if this can not be automated?

Thanks
