NAME

tftpd − DARPA Trivial File Transfer Protocol server

SYNOPSIS

/etc/tftpd [−s] [homedir]

DESCRIPTION

tftpd is a server that supports the DARPA Trivial File Transfer Protocol.  The TFTP server operates at the port indicated in the “tftp” service description; see services(5). The server is normally started by inetd(8).

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

−s Secure.  When 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 tftp service.  The server should have the user ID with the lowest possible privilege.
