tftpd(8c)
Name
tftpd − DARPA Trivial File Transfer Protocol (TFTP) server
Syntax
/usr/etc/tftpd [ −r pathname ]
Description
The server, tftpd, supports the DARPA Trivial File Transfer Protocol (TFTP). The TFTP server is invoked when inetd() receives a packet on the port indicated in the TFTP service description. The server is not normally started by default from inetd(.).
The use of tftp does not require an account or password on the remote system. Because of the lack of authentication information, tftpd will allow only publicly readable files to be accessed. 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 however, and its implications should be considered before enabling TFTP service.
The server should have the user ID with the lowest possible privilege.
Options
−r pathnameThe pathname can be the choice of the user. For example, /guests/ftp would allow only files below /guests/ftp to be copied using tftp.
Restrictions
This server is known only to be self consistent, that is, it operates with the user TFTP program, tftp(.). Because of 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.
