Multi-Homed Configuration passing wrong ip to Remote Clients

[xavierpayne2]

Hello.

I currently have a 2 node JBoss 4.0.1 cluster running. I have two interface adapters in each machine. the first adapter in each has an ip 155.x.x.x that corresponds to our main subnet. The second adapter in each has its own private non-routable ips 192.168.1.x.

I have set the bind_addr of each jboss server to be the internal (192) ip of the machine since I want all multicast cluster traffic to occur over that.

The problem is if I have a client that is not a member of the 192 subnet try to connect to the server (more specifically if I try to do a remote JNDI lookup on an EJB) using the servers 155 address I get the following error:

Failed to connect to server 192.168.1.4

For some reason the client is sucessfully hitting the server but getting HA ips (most likely from the dispatcher) that are in the private subnet!

Am I am doing something wrong? The clustering docs just say to set the bind address to the desired interface.

here is my UDP configuration just in case:

 <UDP mcast_addr="228.1.2.3" mcast_port="48866"
 ip_ttl="64" ip_mcast="true" bind_addr="192.168.1.4"
 mcast_send_buf_size="150000" mcast_recv_buf_size="80000"
 ucast_send_buf_size="150000" ucast_recv_buf_size="80000"
 loopback="false"/>

Use the --host iface startup option to specify that all network interfaces should be using the given iface. The UDP bind_addr is only one piece of several layers when considering an ha lookup and access of an ejb.

Hello,

I'm interesting in knowing how it worked :) I have the same problem (I posted also something on that subject. See http://www.jboss.org/index.html?module=bb&op=viewtopic&t=60168 ). However, the --host parameter didn't really solved my problem, as it seems to force all sockets to be attached to a specific network interface, it means UDP and clients ports. As a result, when I try to open a connection with my client hosted on a PC in the public network, no connection is possible.
Beside, when I use this parameter (--host), the standard shutdown command (jboss_init_redhat.sh) doesn't work properly. I have to "kill -15" the JBoss process.
Is there something I do wrong ?

Thank you, best regards.[/url]
