Sending data to PI via FTP

1. Find an empty FTP slot on the ​ARSF FTP server, if there are not free slots ask someone with root to set one up with a new password:
2. Hardlink the delivery using cp -rl to /users/rsg/arsf/arsf_data/ftp/arsf1 as airborne. Hardlinking rather than rsyncing / uploading via FTP saves space as we don't have multiple copies of the data.
3. Log in to the FTP server and check the data are all there and accessible with the FTP login.
4. Send the FTP server details in the letter to the PI, suggested text is:

   The login details are as follows:
   
   user: USER
   password: PASSWORD
   address: ftp.rsg.pml.ac.uk
   
   link: ftp://USER:PASSWORD@ftp.rsg.pml.ac.uk/
   
   We will remove the data from our FTP server after a month, unless we hear from you access is required for a longer time period. 
   
   We have a guide for downloading data via FTP available from https://arsf-dan.nerc.ac.uk/trac/wiki/FAQ/downloadftp if after following this you are still having problems please contact us to arrange an alternative delivery method.
