[ILUG] FTP servers with triggers

[Niall O Broin]

Hi all,
	Does anyone know of a Linux server which supports triggers ? I may
be mixing my metaphors here, as the word trigger is used more in connection
with RDBM systems but I want a similar functionality - I want to do someting
when a file transfer is completed i.e. client uploads a file, and when the
file upload is finished, some process is called (obviously with at least the
name of the uploaded file). 

	One possible use for this, to make things clearer, would be in a
public FTP site for 'doze programs, where incoming programs might perhaps be
scanned for viruses before being made available for download (this is
nothing like what I want to do, BTW, but it's a nice simple understandable
example).



Kindest regards,


Niall


P.S. Don't bother giving me a "Use The Source" answer - I've considered
that, and it's what I will do if no existing server has the functionality.
It couldn't be the hardest thing in the world to add.
