QUESTION:
Are either the "site" or "quote site" commands supported for our
ftp software on aix 3.2? I see them listed as options when I enter
"?" at the ftp prompt, but I keep getting "SITE COMMAND NOT UNDERSTOOD"
when I try to use it. I'd like to be able to ftp directly to my
workstation from a system on the internet, but I first have to "hop"
thru a corporate gateway RS/6000 running AIX 3.2. As I understand
the site command, I should be able to ftp to the gateway and then
use "site" or "quote site" to switch to another host on the internet.

A: I do not believe that ftp provides the exact functionality you want.
I will describe the ftp sub-commands "site" and "quote", and then
I will discuss how to use the "proxy" sub-command (which is the
sub-command closest to the functionally you said you wanted).
The syntax of the "site" sub-command is:
site help|umask|idle|chmod
not merely "site" by itself. None of "site"'s four options allow you
to connect to a remote host.
The "quote" sub-command sends certain ftp sub-commands to the remote
host without interpreting them. For example, if you enter
"quote user root" you must also enter "quote pass " which
displays root's password on the screen. But if you enter
"user root" ftp will prompt you for root's password and not
display it on the screen.
The "proxy" sub-command allows you to connect to two remote hosts
simultaneously. For example, if I am on host "bravery" I can
connect to host "u2e", and then from "u2e" I can connect to host
"festere". However, I was unable to find a way to transfer a
file directly from "festere" to "bravery".
Following the principle that "a picture is worth a thousand words",
I have appended below a script of an ftp session which illustrates
how to use the "proxy" sub-command. I added comments in the right
margin marked with asterisks. The "skeleton flow" of the script is:
ftp to u2e from bravery
connect to festere from u2e
put a file from festere to u2e <--- note that this is
counter-intuitive
get that file from u2e to bravery
If I have misunderstood your question, or if you want to clarify
anything I have written, please feel free to update this item.
