tftpd(1M)                       TCP/IP R4.11                       tftpd(1M)


NAME
       tftpd - Trivial File Transfer Protocol server

SYNOPSIS
       tftpd [ -d ] [ -s ] [ homedir ]

DESCRIPTION
       The tftpd server supports the DARPA Trivial File Transfer Protocol
       (TFTP). Users of tftp from other network hosts can log on to a host
       that runs tftpd and transfer files. The users need not have accounts
       on the tftpd host and need not enter passwords.

       The tftpd server is invoked by the inetd server when it detects an
       incoming connection on the port specified in /etc/services.  See
       inetd(1M) and services(4) for details.

       The options are:

       -d        Debug: each socket created by tftpd will have debugging
                 enabled, with output going to /tmp/tftpd*.

       -s        Secure mode: limit access to files with public access
                 located in homedir, or in /tftpboot if homedir is not
                 specified.

       homedir   Look in homedir for simple (relative) filenames, or in
                 /tftpboot if no homedir is specified. If specified, homedir
                 must be a fully-qualified pathname.

       The tftpd server must be enabled on network hosts that support
       diskless workstations.  On DG/UX systems, tftpd is enabled by default
       in secure mode:

        * Only host files located in /tftpboot can be accessed at all.

        * To be accessed by the tftp get operation, a file must have read
          access assigned for group other.

        * To be accessed by the tftp put operation, a file must have write
          access assigned for group other.

       To change this default, edit the tftpd startup line in the
       /etc/inetd.conf file.

       Enabling tftpd without the -s option creates a potential security
       problem: any tftp user on the network can access any readable file on
       the host. Thus, if you run the program in non-secure mode, you should
       check the access permissions of sensitive files.
