Bug 954017

Description of problem:

mod_cluster only uses the default interface and this currently isn't configurable.


Expected results:

The proxy-list attribute is improved to allow a desired address/interface to be specified for the Jboss side of the proxy connection.


Additional info:

What looks to be the cause from org.jboss.modcluster.mcmp.impl.DefaultMCMPHandler:

        private synchronized Socket getConnection() throws IOException {
            if ((this.socket == null) || this.socket.isClosed()) {
                this.socket = this.socketFactory.createSocket();
                InetAddress address = this.socketAddress.getAddress();
                if ( address instanceof Inet6Address && ((Inet6Address)address).isLinkLocalAddress()) {
                    /* We need to work-around a java6 bug */
                    InetSocketAddress addr = new InetSocketAddress(address, 0);
                    this.socket.bind(addr);
                    this.socket.connect(this.socketAddress, this.socketTimeout);
                } else {
                    // no socket bind. socket connected from default interface.
                    this.socket.connect(this.socketAddress, this.socketTimeout);  
                }
                this.socket.setSoTimeout(this.socketTimeout);
                this.localAddress = this.socket.getLocalAddress();
            }
            return this.socket;
        }


We need a way to change the bind address of this socket through the configuration of the modcluster subsystem
