[geeks] ftp upload renaming

[Charles Shannon Hendrix]

I have a client who wants users to be able to stage new documents to a
UNIX server that processes documents.  The processing involves moving
a document into the right place, reading it and putting parts of it in a
database, etc.

The user's will not have direct access to this machine: they can only
upload files to it.

The client doesn't want the users to be able to upload any filename they
choose, and some I'm looking for a way to have the ftp server take
whatever file they upload and give it a uniform name.  Something simple
like a sequence will be fine.  In other words:

	file0001
	file0002
	file0003
	file0004

It doesn't matter because the files will be processed, put in a
database, and a copy renamed in a structured hiearchy by the
system anyway.

Mainly I just need to avoid user stupidity in the names.

Is there any kind of ftp server that has "upload hooks" to handle things
like this?

The primary limitations:

	- the client program which the users have must be fairly easy to
	  use, so that limits it to fairly common ftp, GUI scp, and other
	  system->system copy programs
	- the client needs to be able to run on MacOS X and Windows
	- the limits on file sizes needs to be very high since the documents
	  can be large 

I know I could take the code for an ftp server and make a modification
to do generation file renames, but I'd like something standard that is
already out there if possible.
