SFT (Simple File Transfer) is a file transfer
program, a bit like rcp. It is designed to
simplify file transfers from one computer to an
another when they are connected to the Internet.
The person receiving the file has to run the
program in server mode (-s), while the sender of
the file has to run the program in client mode
(-c), specifying the destination host IP and the
file names. File integrity is checked by using
checksums.
