Due to the nature of a public account such as guestftp, preparing a file for transfer to the InterNet is a two stage process. Firstly, you need to transfer the file from your machine to uk.ac.nsf.sun, where it will be placed in a general area. You should then login to the guestftp service as usual and retrieve the file from this area. For example, if you have a file foo.c on your local machine, transfer this using the remote filename foo.c , and remote username and password of guestftp . ...
