Correct. These are for the per-node recovery manager.

single network listening software is to give the option for the administrator to specify
at which address the software listens on. JBoss AS also gives this option, it even has a
global system property jboss.bind.address, and every single service except JBossTS can be
separately configured to listen on a particular address, and by default the services
usually are configured to listen on ${jboss.bind.address}.

globally on ports they have no business or need listening on. Of course my servers are
firewalled, so there's no problem of getting rogue connections, but even so, if
I'm running a simple single JBoss AS instance, nothing will ever need to connect to
JBossTS services from outside of the localhost, then I want to configure JBossTS so that
it listens only on localhost.

Presumably you'd want this capability even if you were running JBossTS stand-alone,
i.e., outside of JBossAS? If that's the case, any way we attempt to address this
should work with the JBossAS approach, but not be dependant on it.

Agreed. However, we need to be careful about giving too many configuration options in this
area or crash recovery could be impacted to the point of not working.

configuration option, why would any service in JBoss support it, and why does JBossTS
support configuring even the port at all, if listen address configuration need not be
supported (these two really always go hand in hand).
I think we should support this. The reason we don't is because JBossTS pre-dates
JBossAS development by many years and also virtual hosting/multiple IP addresses per
machine as a typical state of affairs. It may well be that what you're after is still
not that widely needed, because yours is the first suggestion around this and TS has been
pretty widely deployed. However, that doesn't negate the need for it.
