The default port used for +connecting is 874 (one higher than the normal 873) unless overridden in the +environment. You can specify an overriding port via <code>--port</code> or by including +it in the normal spot in the URL format, though both of those require your +rsync version to be at least 3.2.0.</p> +<h2 id="OPTIONS">OPTIONS<a href="#OPTIONS" class="tgt"></a></h2> +<p>If the <strong>first</strong> arg is a <code>--type=SSL_TYPE</code> option, the script will only use +that particular program to open an ssl connection instead of trying to find an +openssl or stunnel executable via a simple heuristic (assuming that the +<code>RSYNC_SSL_TYPE</code> environment variable is not set as well -⁠-⁠ see below). This +option must specify one of <code>openssl</code> or <code>stunnel</code>. The equal sign is +required for this particular option.</p> +<p>All the other options are passed through to the rsync command, so consult the +<strong>rsync</strong>(1) manpage for more information on how it works.</p> +<h2 id="ENVIRONMENT_VARIABLES">ENVIRONMENT VARIABLES<a href="#ENVIRONMENT_VARIABLES" class="tgt"></a></h2> +<p>The ssl helper scripts are affected by the following environment variables:</p> +<dl> + +<dt id="RSYNC_SSL_TYPE"><code>RSYNC_SSL_TYPE</code><a href="#RSYNC_SSL_TYPE" class="tgt"></a></dt><dd> +<p>Specifies the program type that should be used to open the ssl connection. +It must be one of <code>openssl</code> or <code>stunnel</code>.
