Allowing anonymous file uploads
do we let anonymous ftp clients transfer files to our server?"
You can specify any directory in your ~/ftp directory tree to be "upload
only" by creating a ".incoming" file in that directory. For example, to
set up an incoming directory in "ftp/pub/incoming" perform the following
steps at the Telnet/SSH
% mkdir ~/ftp/pub/incoming
% touch ~/ftp/pub/incoming/.incoming
This creates a directory "incoming" that your anonymous login clients
can upload to but cannot download from. This deters "warez"
peddlers from exploiting your site to distribute illicit software.
