From ba2eb355909b474284c4ab68226fcddf60c742d3 Mon Sep 17 00:00:00 2001 From: Badlop Date: Mon, 12 Jan 2009 20:03:02 +0000 Subject: [PATCH] * src/ejabberd_listener.erl: New way to configure IP address and IP version of listener. Support for definition of IP address in string format, and implicit definition of IP version (EJAB-388). Support for defining several listeners: all with same port number but different IP addresses (EJAB-389)(thanks to Fabrice Colliot and Sergei Golovan).
