Ignore bind address for TCP server sockets
------------------------------------------

                 Key: JGRP-569
                 URL: http://jira.jboss.com/jira/browse/JGRP-569
             Project: JGroups
          Issue Type: Task
            Reporter: Bela Ban
         Assigned To: Bela Ban
            Priority: Minor
             Fix For: 2.6


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
