> Make the cluster interface configurable

> Key: TS-767
> URL: https://issues.apache.org/jira/browse/TS-767
> Project: Traffic Server
> Issue Type: Improvement
> Components: Configuration, Network
> Affects Versions: 2.1.8
> Reporter: Arno Toell
> Priority: Minor
>
> I consider the way how Traffic Server opens listening ports dangerous, or at
> least more risky than necessary. Currently ATS allows to configure port
> numbers for the related services, but not the listening interface. Instead it
> binds to 0.0.0.0. Therefore I'd like to suggest
> * -Allow the user to specify a listening interface, don't assume 0.0.0.0
> suits for all setups.-
> * -Disable the "autoconfiguration port" (i.e. 8083 by default) unless
> proxy.local.cluster.type is set to enable clustering (!= 3). I think
> _traffic_shell_ and eventually _traffic_line_ use this port to configure ATS
> locally. If so it should be bound to the loop back at least or using Unix
> Domain Sockets or whatever local socket method you prefer.-
> * Disable the "reliable service port" (i.e. 8088 by default) unless
> proxy.local.cluster.type enables clustering. Similar to the
> "autoconfiguration port". If _traffic_cop_ (or something else on the local
> machine) is using this port, the same suggestions apply as above.
> * -The "internal communication port" (8084) should not open a public socket
> at all. Instead use Unix Domain Sockets or something similar.-
> n.b. striked through issues are obsolete or tracked in TS-765. For the
> remaining issue is worth to be added the comment from TS-765:
> 8088 is no problem anymore until clustering is enabled, so there is only the
> TS-766 improvement left there. However if enabled, I think it is still fairly
> useful to allow the user to bind to a specific IP. Say, you run a public
> facing proxy in cluster mode where you want to communicate in between on
> private IPs between cluster peers.
