This is a server daemon, port scanner and (optionally) clients for FSP, the File Service Protocol. FSP is lightweight and connectionless. It is typically used for offering files to "anonymous" visitors over a congested link. It uses UDP rather than TCP sockets. A service contact port (well-known port) for FSP has not been assigned by IANA (per RFC 1700). See for an overview. To use fspd, you must copy the fspd.conf.sample file, normally installed in /usr/local/etc/, to fspd.conf and edit it. You can run fspd from inetd or stand-alone. WWW: http://fsp.sourceforge.net/
