[Opensim-users] Diva Distro - Hitting Walls

Sun Nov 28 08:36:03 UTC 2010

The external users are fine, we are able to get into the grid without
trouble; it's the guy inside the network who can't get into the grid, he
gets the handshake problem, even though we thought he had the loopback
problem fixed with the hosts file - even with that, he still cannot get into
the grid.
