Another approach is to use application level proxies, which
spoof a protocol enough that you can (almost always) use the standard
client applications without modification. This approach doesn't conflict
with using SOCKS -- it's just a different design philosophy. For example,
from my PC running Sun's PC-NFS (with no modifications) I do the following:
C:\TMP> FTP RELAY
Connected to relay.tis.com.
220 relay FTP server (Version 5.60mjr) ready.
Name (relay:mjr): anonymous @
331-(----GATEWAY CONNECTED TO research.att.com----)
331-(220 inet FTP server (Version 4.271 Fri Apr 9 10:11:04 EDT 1993) ready.)
331 Guest login ok, send ident as password.
230 Guest login ok, access restrictions apply.
Remote system type is UNIX.
Using binary mode to transfer files.
What SOCKS gives you is the automatic re-routing of the call
(to use X.25ish terms) so the firewall connects to where you really
want to connect. Simple proxies like the FTP proxy I just demonstrated
force the user to manually re-route the call. You notice that instead
of trying to log into the FTP server on RELAY as a user, I told it:
and it "understood" the address and rerouted the call.
A set of proxies for FTP, rlogin, and telnet, are available as
part of the TIS firewall toolkit. (FTP from ftp.tis.com, in
