Shell Programming and Scripting

Hi.

First, I am fairly new to unix scripting (Aix with ksh).
The problem is, I have to transfer a file from a machine A to machine B using ftp. But the script I have to write, needs to be on machine C.

So is there anyway to transfer the files directly form A to B (from C) or do I have to first transfer the file from A to C and then C to B.

thanks..

Tricky but not impossible ... you need to do something like run a script on machine C that rsh's or ssh's to machine A and runs your ftp command (Of course you need to setup trust relationships so that this can be done without passwords).

Unfortunately if its more than a single command then you need to have the script on machine A (or transfer it from machine C) even though its run from machine C

The FTP protocol directly supports server to server transfer.
You initiate it with the proxy client command.
Ages ago I wrote a script to automate this:

pixelbeat, have you tried your script recently? I just tried a 3rd party transfer manually. I got something like this:
ftp> proxy put testfile
servera.abc.com:227 Entering Passive Mode (1,2,3,4,251,85)
serverb:500 Illegal PORT Command

I don't think that many ftp servers still exist that will tolerate a PORT command that specifies a different IP address than the address used to establish the control connection that sent the PORT command.

Nope 1999 was the last time I used FTP.
It truely is an evil protocol.
