Because the old FTP protocol and the associated anonymous ftp login are deemed High Security Risks within the University, we had to dismantle this functionality from our systems. So there is no anon-ftp access to the /disks/ftphome/pub directory structure any more.

However, we have created a more secure form of sharing your science data with your collaborators through an https based WEB service. So you can still easily share your public data with others. It works as follows:

You create (or already have it) a directory in the public NSF share /disks/ftphome/pub, e.g. ED_science_data, and you put the files you want to share in this directory. Make sure the files are world readable (use the command line tool: chown 666 <filename>).

Now you tell your collaborator(s) to get the files from the URL: https://ftp.strw.leidenuniv.nl/ED_science_data. When they open this URL the get a directory listing with the file contents.
