Name
       tftpd - DARPA Trivial File Transfer Protocol (TFTP) server

Syntax
       /usr/etc/tftpd [ -r pathname ]

Description
       The  server, supports the DARPA Trivial File Transfer Protocol (TFTP).  The TFTP server is invoked when receives a packet on the port indi-
       cated in the TFTP service description.  The server is not normally started by default from

       The use of does not require an account or password on the remote system.  Because of the lack of  authentication  information,  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 pathname    The pathname can be the choice of the user.  For example, would allow only files below to be copied using

Restrictions
       This  server  is  known	only  to  be self consistent, that is, it operates with the user TFTP program, 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.

NAME
in.tftpd, tftpd - Internet Trivial File Transfer Protocol server SYNOPSIS
in.tftpd [-s] [homedir] tftpd is a server that supports the Internet Trivial File Transfer Protocol (TFTP). Before responding to a request, the server attempts to change its current directory to homedir; the default directory is /tftpboot. The use of tftp does not require an account or password on the remote system. Due to the lack of authentication information, in.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. in.tftpd runs with the user ID and group ID set to [GU]ID_NOBODY under the assumption that no files exist with that owner or group. How- ever, nothing checks this assumption or enforces this restriction. -d Debug. When specified it sets the SO_DEBUG socket option. -s Secure. When specified, the directory change to homedir must succeed. The daemon also changes its root directory to homedir. The in.tftpd server is IPv6-enabled. See ip6(7P).

The tftpd server only acknowledges the transfer size option that is sent with a read request when the octet transfer mode is specified. The in.tftpd.1m service is managed by the service management facility, smf(5), under the service identifier: svc:/network/tftp/udp6:default Administrative actions on this service, such as enabling, disabling, or requesting restart, can be performed using svcadm(1M). Responsibil- ity for initiating and restarting this service is delegated to inetd(1M). Use inetadm(1M) to make configuration changes and to view config- uration information for this service. The service's status can be queried using the svcs(1) command. Unlike most smf(5) services, a manifest for the tftp service is not included in the system. To create one and enable this service, the administrator should: 1. Edit /etc/inet/inetd.conf and uncomment the tftp entry. 2. Run /usr/sbin/inetconv. After you run inetconv, the svc:/network/tftp/udp6:default service is created and enabled. 8 Mar 2005 in.tftpd(1M)
