[Opensim-users] What happens when you forget to check your sims..

Tue Feb 21 23:43:35 UTC 2012

We've seen that guy before - one useful thing you can do is disable physical primitives for public build regions by tweaking your opensim.ini file:

In the [Startup] section:

physical_prim = false

You can still walk around as normal and rez objects, but you won't end up buried in physical spheres.

Hope this helps,

Chris

I'm with Fleep here. While "griefing" is a nuisance, it's typically very easily remedied by either restarting the simulator, or - at worst - reverting to a previous backup. If anything, I'd encourage people to do regular backups and not neccessarily to rely on server-side restrictions that may or may not work, but will certainly make life harder for the wrong people. The griefers will find a way around them; for them it's a sport, and the harder the obstacle, the more determined they are to overcome it. I think OpenSim even has some kind of auto-backup feature lately that saves regions as OARs. (I'm using the old and dull MySQL dump that works just as well.)
