detecting machine behind proxy

Hi all,
Can anyone give me an idea about how to detect the IPs of
machines behind a Proxy server, from outside ?

e.g. one linux is running squid and serving 5 clients. And I want to
know the IPs of those clients from an another machine which is not in
the same network.
Is it possible ?

thx in advance.

with kind regards
baruah.

Only if they access your web site and you check the HTTP request headers
to see if any tell you that (list all variable in environment). You
CANNOT do it uninitiated from outside, without having some way to get in.

It seems to me, a considerable amount of effort has been expended to
prevent you from being able to learn such things from the outside.

Ask the same person who told you there are 5 clients.
