[Opensim-users] Diva Distro - Hitting Walls

Sat Nov 27 20:25:31 UTC 2010

Yes, we all use the same viewer and the same login url.

He just went to a different computer (still inside his network) and was able
to get the grid info but still hangs at the handshake.

When we do the following in the regions.ini file:

external IP is our-grid.dyndns-server.com  and internal IP is 0.0.0.0

the computers outside the network are able to get into the grid but the UK
guy's computer hangs on handshake - this is even though he has the hosts
file edited as described previously, on each computer in the network;

when we set the following in the regions file:

external IP is 192.168.0.9

our UK guy can log in from inside his network, but the 2 outside computers
can't log in.
