tftpd(8c)
NAME
tftpd − DARPA Trivial File Transfer Protocol server
SYNTAX
/etc/tftpd [ −d ] [ port ]
DESCRIPTION
The tftpd command is a server which supports the DARPA Trivial File Transfer Protocol. The TFTP server operates at the port indicated in the “tftp” service description. For further information, see services(5). This port number may be overridden, for debugging purposes, by specifying a port number on the command line. If the −d option is specified, each socket created by tftpd will have debugging enabled. For further information, see SO_DEBUG in socket(2).
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. 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.
RESTRICTIONS
This server is known only to be self consistent (that is, it operates with the user TFTP program, tftp(1c)). Due to the unreliability of the transport protocol (UDP) and the scarcity of TFTP implementations, it is uncertain whether it really works.
The search permissions of the directories leading to the files accessed are not checked.
