Land Security (how does it work)

OK let me start off by saying I am not new obviously but I am also somewhat confused with all teh changes LL makes what is still right and wrong as far as land security goes. In the last month I have had two accidents that have shown 90% of land security to be false or worthless from what I thought was truth.

1) In the ABOUT LAND menu the Access TAB if set to "group only" or "specific avatars" bans all others not allowed up to 100 meters (50+ meters actual). They are rejected at any height on tp (as if banned) but after that can fly and/or walk into the area as they like. Used one half to test securit and the other half to let the avatars walk in.

2) Banned avatars can fire guns with huge particle explosions into land they are banned from and even TP home everyone in that area (Damage is not enabled in land). Avatars banned on both parcels.

3) When the new land security options to disallow building, scripting, etc to all residents and set to "group only" it does not apply to things coming into the area like vehicles or projectile weapons. Options set on both parcels.

Now the test environment these were all discovered on is about 650 meters in the air, is on the edge of a sim, split into two parcels and was encountered on two different occasions and both reported to LL with little followup or initial care. So I am trying to find out if this is "normal" and if not warn people it IS happening. Can someone help me as I am getting frustrated with land permissions lately.

The release notes archive (I believe it's on the history wiki) should have most of the answers, but I believe your problems in testing are twofold:

1. Non-explicit ban.
2. Height.

Because the map has so many ban all and ban all but group zones they limited those options to (iirc) 50 meters above ground level. Otherwise flying vehicles get caught far too often (it's bad enough as it is w./ sim crossings and "security" orbs). So if you haven't explicitly banned someone they can fly over your land (or walk into the parcel on a high object).

If you'd put someone on the ban list, I believe they are banned up to 750 meters (which I believe is about the limit on non-physical flight on scripted objects).

There was also a pretty fair amount of discussion in some of the forums about these limits when put into place.

wrt objects, if they were fired from off premises, they were not rezzed on your land - moving an object rezzed elsewhere is a long known method of getting something on to land that is set no-build, once again especially w/ vehicles, if you made it different, you'd have vehicles just poofing out from under someone even more often than happens now.

If your main concern is weapons (and the ammo they fire) set the land to no Push.

If someone is excluded from land, because the land is private and they are not a member of the group and/or the "specific avatars" list, then they will see "no entry" lines only going up 100 metres or so, but can still fly over the land.

If someone is banned, because their own name is on the ban list, then they will see "no entry" lines going up forever and they can't enter the land at all.



Yes, banned avatars can move objects into parcels they are banned from. I think this was something due to be fixed in a future version. They shouldn't be able to TP anyone home from the area, though.



No build only disallows new items from being created - it does not prevent new items being moved into the area (although you can use autoreturn to limit that). Turning off scripting only stops scripts from starting new tasks - tasks they were already working on at the time the no-script area is entered still get to finish. (And that's a lot harder to stop because lots of things can be abused if you remove that rule.)

Vehicles and particles are also a special case, because "carrying on emitting particles" and "carrying on being a vehicle" aren't continuous tasks for a script - basically, the script tells Second Life what it wants to do, SL carries on doing it, and the script moves on to other things (or stops entirely).

well honestly the banning ones I understand. I just find it odd it's at 50 meters. I thought it was suppossed to be higher. Also the "offer TP" will still kick people OUT if above the 50 meter mark (say 500 meters above). Example would be "only group" checked for access and TPing in a non group member at 600 meters still pushes them out of land...but they can fly back in.

As for the banned and building/scripting ones seemed I might have my "future releases" and "intial ideas" confused with my "working models"

The TP home though I know DID happen to about 6 avatars last night by the banned griefer.

Thanks so much for helping clear that up though.

The reason for the lower level for "excluded" (as opposed to banned) avatars is so that, by setting your parcel private, you don't create a barrier that anyone else trying to fly across the sim will run into. Someone teleporting into your parcel isn't innocently flying across the sim, so the restrictionstill applies to them.
