+
+The options allowed when starting an rsync daemon are as follows:
+
+startdit()
+
+dit(bf(--daemon)) This tells rsync that it is to run as a daemon. The
+daemon may be accessed using the bf(host::module) or
+bf(rsync://host/module/) syntax.
+
+If standard input is a socket then rsync will assume that it is being
+run via inetd, otherwise it will detach from the current terminal and
+become a background daemon. The daemon will read the config file
+(rsyncd.conf) on each connect made by a client and respond to
+requests accordingly. See the rsyncd.conf(5) man page for more
+details.
+
+dit(bf(--address)) By default rsync will bind to the wildcard address
+when run as a daemon with the --daemon option or when connecting to a
+rsync server. The --address option allows you to specify a specific IP
+address (or hostname) to bind to. This makes virtual hosting possible
+in conjunction with the --config option. See also the "address" global
+option in the rsyncd.conf manpage.
+
+dit(bf(--bwlimit=KBPS)) This option allows you to specify a maximum
+transfer rate in kilobytes per second for the data the daemon sends.
+The client can still specify a smaller --bwlimit value, but their
+requested value will be rounded down if they try to exceed it. See the
+client version of this option (above) for some extra details.
+
+dit(bf(--config=FILE)) This specifies an alternate config file than
+the default. This is only relevant when --daemon is specified.
+The default is /etc/rsyncd.conf unless the daemon is running over
+a remote shell program and the remote user is not root; in that case
+the default is rsyncd.conf in the current directory (typically $HOME).
+
+dit(bf(--no-detach)) When running as a daemon, this option instructs
+rsync to not detach itself and become a background process. This
+option is required when running as a service on Cygwin, and may also
+be useful when rsync is supervised by a program such as
+bf(daemontools) or AIX's bf(System Resource Controller).
+bf(--no-detach) is also recommended when rsync is run under a
+debugger. This option has no effect if rsync is run from inetd or
+sshd.
+
+dit(bf(--port=PORT)) This specifies an alternate TCP port number for the
+daemon to listen on rather than the default of 873. See also the "port"
+global option in the rsyncd.conf manpage.
+
+dit(bf(-4, --ipv4) or bf(-6, --ipv6)) Tells rsync to prefer IPv4/IPv6
+when creating the incoming sockets that the rsync daemon will use to
+listen for connections. One of these options may be required in older
+versions of Linux to work around an IPv6 bug in the kernel (if you see
+an "address already in use" error when nothing else is using the port,
+try specifying --ipv6 or --ipv4 when starting the daemon).
+
+dit(bf(-h, --help)) When specified after --daemon, print a short help
+page describing the options available for starting an rsync daemon.
