This chapter describes the Sun MediaCenter server FTP daemon. This daemon allows any ftp user—on any operating system/hardware platform—to access video ﬁles on a Sun MediaCenter server. In addition to this video server support, the daemon supports the “traditional” FTP functions described in the ftp (1) man page.

The video-ﬁle functions provided by the FTP daemon require no special client-side software. Also, the Sun MediaCenter FTP daemon supports any ftp client that conforms to the FTP protocol, regardless of the platform on which it is running.

FTP client’s support for video ﬁles is illustrated in FIGURE 6-1.
