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

However, standard practice in practically every 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}.

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.

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.
