Re: [Opensim-users] Landmark Auction ID ?

2014-08-22 Thread Luisillo Contepomi

Hello Damean,
I think was some user playing with a script using OSSL functions
http://opensimulator.org/wiki/OsSetParcelDetails

Search in your database, table land  if you have more with the same 
problem.


mysql# select * from land where AuctionID !=0;

OSSL functions are powerfull and must be used with prudence.
Look your OpenSim.ini OSFunctionThreatLevel

Luisillo

Hello Everyone ..  I'm encountering a strange issue.  It seems to crop up
once in a while.  One of the regions on the grid, starting about a week ago,
is showing an Auction ID in the landmark.  I've checked the region DB and
the auction ID field does not contain any valid information and when you
click show on map, the map pointer goes off to some far off place.  When
you attempt to teleport, it says the region no longer exists.

  


The same thing is happening when you choose the region in search and click
'show on map' or you attempt to teleport to the region.

  


This region has been online for months and all has been fine, then this
issue cropped up approx.. one week ago.  We have over 200 regions and this
is the only one experiencing this issue.

  


Would anyone have an idea what might be causing this and how to resolve it?

  


Thank you in advance for your assistance.

  


Kind Regards,

Karl

I always use numeric IPs, with the exception of the external host in
Regions.ini because I'm behind a NAT.

I do use different ports for simulators and regions, but only because I
find it less confusing from an organization standpoint.

The third one is completely new to me. What I do, and I've always suspected
that it's probably a bad idea but have gotten away with it so far, is to
have multiple instances share an asset cache in order to speed things up.

Thank you for your response.  Yes, I have that function disabled for all but

Whats really Odd is, when I open a LM pointing to this region or look it up
in search, it is showing the description field in the location field and
showing the area size to be some astronomical number (like 9 digits long).
So I have no explanation for this.  As I mentioned, all was well with this

There are a number of urban legends floating around opensim. Here are some:

1) It's bad to put numeric IP in ini's.


To be honest, people often advise the opposite, particularly in the region 
config external host.

I'm not entirely sure why - from my experience FQDNs work fine there (I think the simulator might be storing them as IP 
numbers underneath, I can't remember offhand).




2) If your simulator is on port 9000, put your first region on port 1. It 
will reduce latency.


Er, no truth to this at all :)



3) Create a first, empty, hidden simulator in ROBUST's directory (this is for 
ppl that clone the bin/ directory for
each simulator). This will accelerate asset transfers.


Again, not true.

This might come from the fact that simulators have a disk asset cache and some people argue that disk is faster than 
database.  However, when I last looked into this there was no conclusive evidence either way with many people saying 
there's no difference and I've yet to see someone produce comparative benchmarks for the OpenSimulator case.


The asset service is not coded to use any Flotsam cache present anyway.

[Opensim-users] OpenSimulator 0.8.0.1 now available

2014-08-22 Thread Justin Clark-Casey

Hi folks,

I just made OpenSimulator 0.8.0.1 available [1].  This is a bug fix release 
from the 0.8-post-fixes Git branch.

The major reason for this release is to address a Hypergrid teleport regression, where on teleport attachments could 
disappear or sometimes appear twice.


Hence, this is probably of greatest interest to people using the Hypergrid, though this release also contains various 
other fixes that should have low risk of causing regressions.  Please see the release notes [2] for more details.


There are a couple of extra configuration parameters but there are in OpenSimDefaults.ini, so if you aren't changing 
this file (which we strongly recommend you don't!) then you should be fine just using your existing config files.


This release also does not contain any database migrations.

Many thanks to all the developers, testers and other community members who 
contributed to this!

Yeah, I've tried a shared cache before and it seems to be okay.  It's a bit messy because multiple simulators may 
attempt to clean up the cache at the same time, which results in quite a few seeing messy file not found warnings, 
though these should not be harmful.


It's hard to know how to get around this problem without making the cache yet another process or doing messy things like 
designating only one simulator to actually clean up files.  I also think the cache needs a facility to limit by size 
(like every other cache in the known universe :).

Re: [Opensim-users] Urban legends (Was :Configuring a multi-hosted grid)

2014-08-22 Thread Thomas Ringate
I've been running a shared cache now for a couple of years.  I even copy 
them in a round robin fashion between my four servers so they are nearly 
identical.  I turned off the clean up so anything that has been put in them 
for about the last 10 months is still there.


As you can tell I do not have a clue how the cache is used or how it really 
works.  Since every item in is it indexed using the UUID and the first three 
digits of the UUID place them in individual folders, I have not noticed any 
folder being all that large.


The reason I do this is because three of my servers are on OSgrid, the 
fourth is where I do my scripting using two standalones which are mirror 
images of the 64 regions I host on OSgrid.  One standalone is a normal set 
of regions and the other is a single varregion.


I found I had much better success of having things appear on my standalones 
once I consolidated all of the caches, but it is still far from being 
optimal.


Now I am wondering if doing this is causing a performance hit on the three 
servers that host regions for OSgrid???

What do the experts think?

I could merge those cache into the one on the standalone server and have one 
master region clean each servers cache to some appropriate level.  I like 
the idea of a shared cache on each server.  It eliminates redundancy and 
eliminates requests by different regions for the same object.


I was surprised to hear it is not used for assets.  Why is it named 
asset-cache?

Re: [Opensim-users] Urban legends (Was :Configuring a multi-hosted grid)

2014-08-22 Thread Melanie
You can share cache between simulators that use the same central
services, for instance any simulators you use that are on OSGrid.
Don't share caches between services, as the asset ids are not valid
between services and you may wind up creating items that work only
on your own sims and from users' caches, but fail visually in
mysterious ways when taken off-sim.

There is some (yellow) spew occasionally, it's trivial to catch and
prevent in code, if you're so inclined. We have been ignoring it
ever since the cache was written, with no ill effects.

 in less network traffic, and also a modest
 speed up when regions are first started in some circumstances.

 Because an asset may have been cached already by another simulator.



 My only concern has been that a single asset cache that has multiple 
 copies of Flotsam managing it might at some point
 encounter some sort of conflict or collision. So far, I've noticed nothing 
 of the sort, though. In practice, a single
 asset cache has been working fine for me.

 So shared cache is a better option, until we discover a drawback.

[Opensim-users] loopback question

2014-08-22 Thread Thomas Ringate
I have a basic understanding of what loopback is, and I think I understand why 
opensim requires this function.

My question is about any possible alternative if it is not supported by your 
ISP.

The opensim wiki suggests that the Verizon FIOS service and in particular the 
Actiontec MI424WR router supports loopback.  After spending a rather large 
amount of time and money with Verizon’s “premium” support, and long discussions 
with the Actiontec support people, it is clear that router does NOT support 
loopback.  Unfortunately Verizon in central Florida provides no other choice 
for the router they use in their service.

There is a very excellent alternative which is to place your own router that 
does support loopback between their router and the ONT.  This is in fact what 
most of their commercial customers do.  I attempted to do this, and for the 
week or so of my testing it was heaven.

Now I am a residential customer, and my wife has become rather dependent on 
“caller ID” appearing on our TV screens.  As luck would have it, unless the 
Actiontec router is the router directly connected to the ONT that feature does 
not work.  If you can do without that one feature, placing a router which 
supports loopback between the ONT and their router works perfectly for 
everything else.

I have tried every possible combination of using host files, DNS in the 
routers, different domain names.  Nothing so far can trick opensim to not use 
the FQDN of the network facing address for a destination that is on the local 
LAN.  Hence, it needs loopback.

The problem I see is:  because Verizon “kind of supports loopback”, which can’t 
really be explained by anyone, it responds very slowly and often gives the 
wrong addresses in the reply packets.  This results in lots of timeouts and 
eventually failure of the specific transmission.  Because this operation is not 
consistent, but rather random, sometimes things work and sometimes they don’t.

This manifests itself for me as a “client” with very slow logins, almost no 
chance of completing a TP within my set of regions, difficulty in saving 
notecards and scripts, and I suspect it causes problems for outside clients 
trying to TP between my own regions as well.  I have lived with this for 2 
years now, my choice, but I was wondering if there is some possible workaround 
for this I have not yet explored???

I know I can configure things to be “local” or “remote” and everything works 
wonderful.  Configurations that allow both inside and outside local LAN work 
rather poorly but my present configuration focuses that poor functionality to 
me inside my local LAN.

I do know I can get a second service from Verizon, use my own modem on it, and 
use it for my servers.  That becomes a rather expensive solution over time for 
my hobby.
