Summary: Cannot bind to a specific interface

Initial Comment:
I would like to be able to bind to specific interfaces,
specifically 127.0.0.1, however it appears that this is
not possible. I looked briefly for where to make the
changes and the only place I can find where a
ServerSocket is even used is in the apache JNDI stuff.
If someone can point me in the right direction to get me
started I'll gladly make the changes and submit a patch.

When I leave the host attribute of the ServerConfiguration
parameter set to "localhost" (as it is by default) or set it
explicitly to "127.0.0.1" as you tanderson suggested, the
server binds to all interfaces on the machine (0.0.0.0) and
not just 127.0.0.1.

I would like to be able to bind to JUST 127.0.0.1 (or the
address of any other specific interface, instead of 0.0.0.0
which is the address that maps to all interfaces).

Again, I'd be happy to make the changes but I have not yet
found the place in the code where the binding is done, so any
guidance would be helpful.

I'm not exactly sure what you're trying to do, but you should
be able to configure the server for 127.0.0.1. E.g,
in openjms.xml:

<ServerConfiguration host="127.0.0.1"/>

As for the JNDI code - the part you're referring to isn't used
by OpenJMS.

It looks like maybe the connections are being created in the
init() method of the org.exolab.jms.server.mipc.IpcJmsServer
class through a call to the .createServer(int port) method
which creates a new org.exolab.jms.server.mipc.IpcJmsServer
which only has a single interface which just takes the port to
listen on and the ConnectionNotifier to notify... so if I'm not
mistaken, all of this stuff would have to be updated to take
an optional address to bind to. If the source is available for
the exolabcore stuff, I'll take a shot at it....

I have the changes to openjms working as needed for my
environment, however I'm trying to figure out how to handle
it for the general case.

Right now I use the host attribute of the ServerConfigurartion
as the interface for JNDI to bind to, and if the server is using
TCP mode, I use the internalHost attribute of the
TcpConfiguration if present, otherwise, the host attribute of
the ServerConfiguration as the interface for the TCP server
to bind to. I think this seems like the "right way" to do it,
however this means that using the default configuration files,
or any configuration files that existing users don't change
(from "localhost" to "0.0.0.0") that the server will suddenly
only bind to localhost (127.0.0.1) and not all interfaces.
Obviously the existing configuration files can be changed to
replace "localhost" with "0.0.0.0", however this will affect
existing deployments, so I guess it's up to you how to
proceed.

If you like, I can submit my patches as-is, and let you figure
it out, or if there is another way you'd like it handled I can go
ahead and make the changes.

An alternative would be to add seperate attributes specifying
the interface to bind JNDI and the TCP server to, but it
seems like this might clutter up the configuration file.

Let me know how you would like to proceed.

You could add another property to the config file
named 'bindAll' or something similar. If true, this result in the
ServerSocket(port) constructor being called. If false, the
ServerSocket(port, ... address) constructor would be used. It
would default to true, to retain existing behaviour.

You'll need to modify
src/main/org/exolab/jms/config/openjms.xsd to extend the
config file. It would become an attribute of the
<ServerConfiguration> element.

I'm not exactly sure what you're trying to do, but you should
be able to configure the server for 127.0.0.1. E.g,
in openjms.xml:
