+Hi,&lt;br&gt;<br>
+&lt;br&gt;<br>
+I&#39;m&nbsp;new&nbsp;to&nbsp;ranch.&nbsp;In&nbsp;my&nbsp;application,&nbsp;I&nbsp;need&nbsp;to&nbsp;send&nbsp;some&nbsp;message&nbsp;to&lt;br&gt;<br>
+all&nbsp;connections.&nbsp;So&nbsp;I&#39;d&nbsp;like&nbsp;to&nbsp;know&nbsp;can&nbsp;I&nbsp;get&nbsp;all&nbsp;connections&nbsp;from&lt;br&gt;<br>
+ranch,&nbsp;so&nbsp;I&nbsp;could&nbsp;use&nbsp;Transport:send&nbsp;to&nbsp;send&nbsp;them,&nbsp;or&nbsp;I&nbsp;must&nbsp;manage&lt;br&gt;<br>
+all&nbsp;the&nbsp;created&nbsp;connections&nbsp;by&nbsp;myself?&nbsp;Or&nbsp;is&nbsp;there&nbsp;any&nbsp;other&nbsp;better&lt;br&gt;<br>
+way?&lt;br&gt;<br>
+&lt;/blockquote&gt;<br>
+&lt;br&gt;&lt;/div&gt;<br>
+The&nbsp;best&nbsp;way&nbsp;to&nbsp;do&nbsp;that&nbsp;is&nbsp;on&nbsp;your&nbsp;end,&nbsp;using&nbsp;gproc&nbsp;properties.&nbsp;When&nbsp;the&nbsp;connection&nbsp;is&nbsp;accepted,&nbsp;register&nbsp;the&nbsp;process&nbsp;with&nbsp;the&nbsp;property&nbsp;and&nbsp;use&nbsp;the&nbsp;property&nbsp;to&nbsp;send&nbsp;messages&nbsp;to&nbsp;all&nbsp;processes.&nbsp;You&nbsp;don&#39;t&nbsp;need&nbsp;to&nbsp;unregister&nbsp;when&nbsp;the&nbsp;connection&nbsp;ends,&nbsp;gproc&nbsp;does&nbsp;that&nbsp;automatically.&lt;br&gt;<br>
+<br>
+&lt;br&gt;<br>
+The&nbsp;hackish&nbsp;way&nbsp;to&nbsp;do&nbsp;that&nbsp;would&nbsp;be&nbsp;to&nbsp;call&nbsp;supervisor:which_children&nbsp;on&nbsp;the&nbsp;ranch_conns_sup&nbsp;supervisor&nbsp;of&nbsp;your&nbsp;listener,&nbsp;but&nbsp;that&nbsp;will&nbsp;slow&nbsp;down&nbsp;the&nbsp;accepting&nbsp;of&nbsp;new&nbsp;connections,&nbsp;so&nbsp;don&#39;t&nbsp;do&nbsp;this&nbsp;if&nbsp;you&nbsp;need&nbsp;high&nbsp;accept&nbsp;rates.&lt;span&nbsp;class=&quot;HOEnZb&quot;&gt;&lt;font&nbsp;color=&quot;#888888&quot;&gt;&lt;br&gt;<br>
