# tftpd - Info
#
# tftpd is a server which supports the DARPA Trivial File Transfer
# Protocol. This server should not be started manually; instead, it
# should be run using launchd using the plist
# /System/Library/LaunchDaemons/tftp.plist. It may be started
# using the launchctl load command.
#
# The use of tftp(1) 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.
# Filenames beginning in ``../'' or containing ``/../'' are not
# allowed. Files may be written to only if they already exist and
# are publicly writable.
