10 in.tftpd, tftpd \- Internet Trivial File Transfer Protocol server
14 \fBin.tftpd\fR [\fB-d\fR] [\fB-T\fR \fIrexmtval\fR] [\fB-s\fR] [\fIhomedir\fR]
19 \fBtftpd\fR is a server that supports the Internet Trivial File Transfer
23 Before responding to a request, the server attempts to change its current
24 directory to \fIhomedir\fR; the default directory is \fB/tftpboot\fR.
27 The use of \fBtftp\fR does not require an account or password on the remote
28 system. Due to the lack of authentication information, \fBin.tftpd\fR will
29 allow only publicly readable files to be accessed. Files may be written only if
30 they already exist and are publicly writable. Note that this extends the
31 concept of "public" to include all users on all hosts that can be reached
32 through the network. This may not be appropriate on all systems, and its
33 implications should be considered before enabling this service.
36 \fBin.tftpd\fR runs with the user \fBID\fR and group \fBID\fR set to
37 \fB[GU]ID_NOBODY\fR under the assumption that no files exist with that owner or
38 group. However, nothing checks this assumption or enforces this restriction.
45 Debug. When specified it sets the \fBSO_DEBUG\fR socket option.
54 Secure. When specified, the directory change to \fIhomedir\fR must succeed. The
55 daemon also changes its root directory to \fIhomedir\fR.
61 \fB\fB-T\fR \fIrexmtval\fR\fR
64 Specifies the value of the retransmission timeout in seconds. This also affects
65 the maximum session timeout in that the latter is set to five times the
66 retransmission timeout value.
71 The \fBin.tftpd\fR server is IPv6-enabled. See \fBip6\fR(7P).
73 \fBin.tftpd\fR supports transfers of greater than 32 MB, per RFC 2348.

96 The \fBtftpd\fR server only acknowledges the transfer size option that is sent
97 with a \fBread\fR request when the octet transfer mode is specified.
99 The \fBin.tftpd.1m\fR service is managed by the service management facility,
100 \fBsmf\fR(5), under the service identifier:
104 svc:/network/tftp/udp6:default
111 Administrative actions on this service, such as enabling, disabling, or
112 requesting restart, can be performed using \fBsvcadm\fR(1M). Responsibility for
113 initiating and restarting this service is delegated to \fBinetd\fR(1M). Use
114 \fBinetadm\fR(1M) to make configuration changes and to view configuration
115 information for this service. The service's status can be queried using the
116 \fBsvcs\fR(1) command.
