[jboss-jira] [JBoss JIRA] Resolved: (JGRP-569) Ignore bind address for TCP server sockets

[Bela Ban (JIRA)]

     [ http://jira.jboss.com/jira/browse/JGRP-569?page=all ]

Bela Ban resolved JGRP-569.
---------------------------

    Resolution: Done

Fixed in ConnectionTable (ConnectionTableNIO needs further review, especially as we'll merge it into ConnectionTable).
Not done for FD_SOCK, as we don't accept connections on other NICs

> Currently, we use the interface defined by bind_addr (or -Djgroups.bind_addr) to bind TCP server sockets to. We might ignore this and simply bind the TCP server socket to *all* NICs, e.g. by replacing
> ServerSocket srv_sock=new ServerSocket(port, length, bind_addr)
> with
> ServerSocket srv_sock=new ServerSocket(port).
> The advantage is that in the latter case, the server socket will accept packets to the given port from *any* (wildcard) interface (0.0.0.0), whereas in the former case it will accept packets only from bind_addr.  This reduces chances of misconfiguration.
> Example: {Basic}ConnectionTable, FD_SOCK
