[Opensim-users] Any way to display the values of "IP" and "MyIP"

Wed Apr 11 18:44:02 UTC 2012

Unfortunately I have this issue too and if there's a way to trick it into
working using the hosts file, I guess I haven't figured it out.

Essentially I can't use the hypergrid from any of the machines on my
internal network except the server, which I don't do very often because
it's completely inconvenient.  If I really must hypergrid around to other
grids, I start with a local account on someone else's grid to get around,
but I can never HG to or from my own grid.  It's a bummer. :(
