. The Guest FTP Service at the University of London Computer Centre provides a gateway service between InterNet file transfer protocol (FTP), and the file transfer mechanism used over JANET (Blue Book NIFTP). Suppose you can only transfer files between your local host and other remote hosts on JANET using the hhcp command. This service enables you to transfer files to and from hosts on the InterNet through its gateway.
