[Opensim-users] Region XML file - master_avatar_authentication_address

[Ai Austin]

Can someone remind me what the entry

     master_avatar_authentication_address="<external-hostname>:10001"

in a Region\*.xml file is for?

it seems to be added automatically... if its needed for external 
access, does ort 10001 need to be opened in the firewall as well as 
8001-6 for the services and 9000+ for the regions?
