You have the possibilities:
You can create your own subusers with "user config & operation control" (you see this link when you are logged in).
A subuser can send you as many files as he wants.
This one-time upload key is an URL you have to give to your communication partner.
fexsend -U
which generates an upload URL and a shell function that you can give your communication partners.
To use public upload the fexmaster has to set in /home/fex/lib/fex.ph the public recipients. Example:
@public_recipients = ($admin,'framstag@rus.uni-stuttgart.de');Afterwards one can use http://YOURFEXSERVER/pup
You may test it.
