Firewall Wizards: ms proxy 2.0 again

[aurelio rodriguez <aurelio_r () usa net>]

Some time ago i posted here a question relative to ms proxy 2.0. I asked
about how could i use client programs in a unix environment (ftp , mail ...
) thru it ( i mean we have a lan connection with a ISP and , between , a NT
with ms proxy. We can use all clients thru windows having already installed
the proxy client, but not with unix. I got one reply in the terms of "use
socks to accomplish that" . The fact is that i would like to have a little
( or a big ) more information about this. I've read several related
postings (linux &msproxy newsgroups) with no solution. Any info would be
greatly appreciated.
