rsync zu bestimmtem SSH Port

Wenn man Daten via rsync zu einem Zielrechner synchronisieren möchte, der nicht auf dem Standard-SSH-Port 22 lauscht, muss man das rsync Kommando etwas anpassen. Der Ausschnitt aus der man page von rsync, der verrät wie es geht:

-e, --rsh=COMMAND
This option allows you to choose an alternative remote shell program to use for communication
between the local and remote copies of rsync. Typically, rsync is configured to use ssh by
default, but you may prefer to use rsh on a local network.
If  this option is used with [user@]host::module/path, then the remote shell COMMAND will be
used to run an rsync daemon on the remote host, and all data will be transmitted through that
remote shell connection, rather than through a direct socket connection to a running rsync
daemon on the remote host.  See the section "USING RSYNC-DAEMON FEATURES VIA A REMOTE-SHELL
Command-line arguments are permitted in COMMAND provided that COMMAND is presented to rsync
as a single argument.  You must use spaces (not tabs or other whitespace) to separate the
command and args from each other, and you can use single- and/or double-quotes to preserve
spaces in an argument (but not backslashes).  Note that doubling a
single-quote inside a single-quoted string gives you a single-quote; likewise for double-
quotes (though you need to pay attention to which quotes your shell is parsing and which
quotes rsync is parsing).  Some examples:
    -e 'ssh -p 2234'
    -e 'ssh -o "ProxyCommand nohup ssh firewall nc -w1 %h %p"'
(Note that ssh users can alternately customize site-specific connect options in their
.ssh/config file.)
You can also choose the remote shell program using the RSYNC_RSH environment variable,
which accepts the same range of values as -e.
See also the --blocking-io option which is affected by this option.

Man kann also den Port wie folgt angeben:

rsync -e "ssh -p 12345" daten zielrechner:

Mit diesem Kommando wird die Datei daten auf den Zielrechner kopiert, dessen SSH Daemon auf Port 12345 lauscht.
