 Name

    tftpd - DARPA Trivial File Transfer Protocol server

 Syntax

    /etc/tftpd [ -s ] [ homedir ]

 Description

    tftpd is a server that supports the DARPA Trivial File Transfer Protocol
    (TFTP).  This server is normally started by inetd(ADMN) and operates at
    the port indicated in the tftp Internet service description in the
    /etc/inetd.conf file. By default, the entry for tftpd in etc/inetd.conf
    is commented out.  To make tftpd operational, the comment character(s)
    must be deleted from the file.  See inetd.conf(SFF) for details.

    Before responding to a request, the server attempts to change its current
    directory to homedir; the default value is tftpboot.

 Options


    -s   Secure.  When the secure option is specified, the directory change
         must succeed; and the daemon also changes its root directory to
         homedir.

    The use of tftp does not require an account or password on the remote
    system.  Due to the lack of authentication information, tftpd will allow
    only publicly readable files to be accessed.  Files may be written only
    if they already exist and are publicly writable.  Note that this extends
    the concept of ``public'' to include all users on all hosts that can be
    reached through the network; this may not be appropriate on all systems,
    and its implications should be considered before enabling this service.

 Notes

    Due to the limitations of the TFTP protocol, the integrity of the data
    cannot be guaranteed for multiple file transfers using the get or put
    commands.
