scp uses an ssh channel to securely transfer files. Rather like
an encrypted rcp. User interface is command line, for example,
scp /tmp/foo user@host:/tmp/bar
-or- pscp /tmp/foo user@host:/tmp/bar (putty scp for Windows)
Datafellows Windows ssh does not appear to have a gui for
transferring files, though it does also come with a command-line
ftp-style client.
You might find it easier to use a normal ftp client over
an ssh or SSL tunnel (which, for ssh, could be a Java applet such
as Mindterm or Mindtunnel http://www.mindbright.se/, or a normal
ssh client). So clients would connect to a port on their own
local host, which would get forwarded over the ssh encrypted
/compressed [1] channel. This may need some fiddling - you may
have to search around and try things to work out the details
of documentation.
The original ssh has been ported to run under cygwin, and I
guess you could probably wrap a gui around the code to make
it a little easier for end-users (otherwise, any documentation
would have to be *very* clear and accurate), so there are some
things to try.
Putty[2] isn't suitable for setting up tunnels (although as a
Windows telnet and ssh client, it's very nice - though copying
more than one screenful to the clipboard is on the todo list
rather than the features list ;)
[1] At this point, it might be worth drawing the attention of
anyone working at an ISP in a country relying on limited and
probably rather expensive international leased lines to the
fact that if you have boxes close to the other side of your
line on which you can run a proxy and a compressed ssh
tunnel, you should be able to make somewhat more effective
use of your pipe.
[2] with an added note for American readers that they need to
find something else if they want to use it legally now rather than
after the RSA patents have expired ;-) you can find a copy of
Putty here, http://www.chiark.greenend.org.uk/~sgtatham/putty
(If you don't like something about the release version, try the
development one instead). It's open source, and the license is
free and nonrestrictive.
