This page gives any system-specific configuration settings that may be useful, and advice for problems that might be encountered.

General tips

If OpenSim does startup to a point where you can type commands in the region console, then you can find out what your current configuration is by using the "config get" and "config save" commands as detailed at Server_Commands (and by typing help on the console).

This can be useful for eliminating a bad configuration when diagnosing some issues.

System-specific configuration

CentOS 5

To install mono and nant, you can use the "Linux Installer for x86" found at http://www.mono-project.com/Downloads.

SVN can be installed by:

yum install subversion

Mono defaults to installing into /opt, so you may have to add this path to your environment variables, for example, in your ~/.bashrc:

export PATH="/opt/mono-1.2.5/bin:$PATH"
export PKG_CONFIG_PATH="/opt/mono-1.2.5/lib/pkgconfig:$PKG_CONFIG_PATH"
export MANPATH="/opt/mono-1.2.5/share/man:$MANPATH"
export LD_LIBRARY_PATH="/opt/mono-1.2.5/lib:$LD_LIBRARY_PATH"

After changing LD_LIBRARY_PATH, you should update the dynamic linker cache:

ldconfig

You may still encounter the "The current runtime framework 'mono-2.0' is not correctly configured in the NAnt configuration file." error listed below. In that case, this may fix this:

yum install glib

If you are running a firewall as well (i.e., if iptables -L shows a list of ACCEPT and REJECT rules), you'll have to open the necessary ports if you want to access the sim from other machines. For standalone mode:

iptables -I RH-Firewall-1-INPUT -p tcp --dport 9000 -j ACCEPT
iptables -I RH-Firewall-1-INPUT -p udp --dport 9000 -j ACCEPT

If you are running Mono 2.2 compiled from source on CentOS 5.2 64bit (not sure if it applies to other scenarios as well), you need to take these steps:

sudo yum install libgdiplus
sudo yum install libexif
sudo ln -s /usr/lib64/libgdiplus.so.0 /usr/lib64/libgdiplus.so
ldconfig

That finally enabled me to run OpenSim without errors, and even connect to other grids.

Debian 4.0r0

If you set your system to use unstable sources, and then install some packages listed below, everything should just work. To use unstable sources, modify your /etc/apt/sources.list file, replacing 'etch' or 'stable' with 'unstable':

deb ftp://ftp.debian.org/debian/ unstable main
deb-src ftp://ftp.debian.org/debian/ unstable main

Then update your packages to the new versions:

apt-get update
apt-get dist-upgrade

This will probably change a large number of packages, and may break things. In my experience, however, if you do not use unstable sources then the packages are not up to date enough, and you run into version issues, which lead to two DllNotFoundException errors below appearing in the console output: gdiplus.dll and libopenjpeg-libsl-2.1.2.0.so.

Once the sources are updated, we need to install the necessary packages to be able to build OpenSim:

apt-get install subversion mono nant mono-gmcs mono-mjs libmono-microsoft8.0-cil libmono-system-runtime2.0-cil

If any of these packages are missing, you'll probably encounter one of the errors listed below. However, with these packages, OpenSim should build cleanly.

Please note: If you are using mysql as storage on unstable you may get the following error:-

Exception: System.NotSupportedException: CodePage 1252 not supported
 at System.Text.Encoding.GetEncoding (Int32 codePage) [0x00000] 

To get it to work, try installing the libmono-i18n2.0-cil package

apt-get install libmono-i18n2.0-cil

Gentoo

some Mono dependency & latest Mono itself may use "~x86" masked packages (assuming x86 is your platform, change may be made to reflect your ex:"~amd64" for 64bits). You could check for USE parameter with:

ACCEPT_KEYWORDS="~x86" emerge -vp subversion nant mono libgdiplus

Then install with:

ACCEPT_KEYWORDS="~x86" emerge subversion nant mono libgdiplus

N.B: The ACCEPT_KEYWORDS="~x86" can be set in Gentoo /etc/make.conf file, but that turn up all the emerges in testing/unstable, using it at the begining of emerge command line use it only for current emerge process

Mac OS X

This assumes you're using the universal binary for mono from the Mono Project site.

If you are using OS X 10.4, you should also install X11 from the OS X install CDs. In OS X 10.5, this is not required.

If you get errors about the 2.0 framework not being supported, you may need to update your pkg-config path. I set this in ~/.bash_profile:

export PKG_CONFIG_PATH="/Library/Frameworks/Mono.framework/Versions/Current/lib/pkgconfig/:${PKG_CONFIG_PATH}"

Errors and fixes

Build workarounds due to non-functionality or bugs:

Disappearing prims due to duplicate UID's

Generally this problem occurs when a save-xml/load-xml file is loaded into the same sim without using the -newUID switch to generate new UUID's for the objects. See Server_Commands for detailed information. (load-xml <filename> -newUID). But if this does not work, the other way is to shift-copy your build and drag it up into the air.. then delete the one in the air, (which is actually the copy). This will generate new UID's on all your prims.. you can now leave that build, and load your original load-xml file in another region.

Exception and loss of ode physics (System.EntryPointNotFoundException: dSpaceLockQuery)

The following error is usually caused by using the wrong version of libode:

First try searching your filesystem to see if you have other copies of the ode physics engine:

find / -name "libode.so"

Then make sure you have the latest version.

MySQL connection errors after about 6-8 hours

MySQL has a timeout which drops the connection after 28,800 seconds (8 hours) of inactivity, which will probably result in failure to login after the User server has been sitting idle for an extended period. If you have this problem, increase the timeout to something larger, like 604800 (1 week) or 31536000 (1 year). From the mysql console, type:

set global wait_timeout=604800;

System.DllNotFoundException: gdiplus.dll

First, check to make sure that libgdiplus.so is known to the dynamic linker:

/sbin/ldconfig -p | grep libgdiplus

If nothing is found, make sure that the directory libgdiplus.so exists in is either in your LD_LIBRARY_PATH environment variable or listed in a *.conf file (e.g., gdiplus.conf) in /etc/ld.so.conf.d/. Then run ldconfig to update the cache. Then it should be able to find the library.

You may still have the above error, however, since libgdiplus also depends on other dynamic libraries, and if they fail to load, libgdiplus will fail. To test for this, run OpenSim with debugging information turned on:

MONO_LOG_LEVEL=debug mono OpenSim.exe

On Mac OS X - check the following file exists... /opt/local/lib/libgdiplus.dylib if it does then as root user edit the file /opt/local/etc/mono/config and add the line

<dllmap dll="gdiplus.dll" target="/opt/local/lib/libgdiplus.dylib" os="!windows"/>

Migrating Opensim / MySQL database from Windows to Linux

MySql.Data.MySqlClient.MySqlException: Table 'opensim.UserAccounts' doesn't exist

Environment: Opensim Server 0.7.0.2 behind Linux Ubuntu 8.0.4 with mono 2.8 and MySQL 5.0 installed.

When you migrates a Opensim 0.7 database working with MySQL 5.0 on Windows to Linux, when logging a user in Opensim server, you may receive the following exception in the Opensim server console:

 03:11:10 - [LLOGIN SERVICE]: Exception processing login for (user_name): MySql.Data.MySqlClient.MySqlException: Table 'opensim.UserAccounts' doesn't exist
at MySql.Data.MySqlClient.MySqlStream.OpenPacket () [0x00000] in <filename unknown>:0
at MySql.Data.MySqlClient.NativeDriver.ReadResult (System.UInt64& affectedRows, System.Int64& lastInsertId) [0x00000] in <filename unknown>:0
at MySql.Data.MySqlClient.MySqlDataReader.GetResultSet () [0x00000] in <filename unknown>:0
at MySql.Data.MySqlClient.MySqlDataReader.NextResult () [0x00000] in <filename unknown>:0    at MySql.Data.MySqlClient.MySqlStream.OpenPacket () [0x00000] in <filename unknown>:0
at MySql.Data.MySqlClient.NativeDriver.ReadResult (System.UInt64& affectedRows, System.Int64& lastInsertId) [0x00000] in <filename unknown>:0
at MySql.Data.MySqlClient.MySqlDataReader.GetResultSet () [0x00000] in <filename unknown>:0
at MySql.Data.MySqlClient.MySqlDataReader.NextResult () [0x00000] in <filename unknown>:0

On the client, you also receive the following error:

Login Failed
Error generating Login Response

This exception is caused by the way MySQL store the table names. On a Windows MySQL server, the table names are not case sensitive, but all tables in MySQL Linux are case sensitive by default, so when OpenSim will find them in the database with names in first capital letters, it can not find it.

One solution would be to change the names of the tables required by opensim (ALTER TABLE's), but the cleanest solution is changing MySQL config, checking the option “lower_case_sensitive = 1” in the file "/etc/mysql/my.cnf", section [mysqld].

# sudo nano /etc/mysql/my.cnf

..........................
[mysqld]
..........................
lower_case_sensitive=1
..........................

This makes MySQL translate to lowercase the table names automatically. After restarting MySQL server and OpenSim, the tables are loaded without problems.

Warning: don’t try to clear the table migration to force opensim re-migrate your database, because it will provoke a blight on your database.

Errors from incomplete data migrations

This can happen during version upgrades if for some reason a database migration fails when there is a change in the way OpenSim stores data.

You may see errors on the OpenSim console like:

 [LLOGIN SERVICE]: Exception processing login for [username]: MySql.Data.MySqlClient.MySqlException: Table 'opensim.UserAccounts' doesn't exist
 at MySql.Data.MySqlClient.MySqlStream.OpenPacket () [0x00000] 
 at MySql.Data.MySqlClient.NativeDriver.ReadResult (System.UInt64& affectedRows, System.Int64& lastInsertId) [0x00000] 
 at MySql.Data.MySqlClient.MySqlDataReader.GetResultSet () [0x00000] 
 at MySql.Data.MySqlClient.MySqlDataReader.NextResult () [0x00000]    at MySql.Data.MySqlClient.MySqlStream.OpenPacket () [0x00000] 
 at MySql.Data.MySqlClient.NativeDriver.ReadResult (System.UInt64& affectedRows, System.Int64& lastInsertId) [0x00000] 
 at MySql.Data.MySqlClient.MySqlDataReader.GetResultSet () [0x00000] 
 at MySql.Data.MySqlClient.MySqlDataReader.NextResult () [0x00000] 

In this case the 'users' table had not been migrated to the 'UserAccounts' table which OpenSim was expecting, also resulting in the viewerside error:

 Login Failed
Error generating Login Response

I solved by fixing the filesystem permissions that were causing the migration to fail (on my Linux box '/var/lib/mysql/...' had got itself messed up), then dropping the 'migration' table and running the server again (from the [non-critical] migration warnings encountered there was probably a more precise way to do this, but I was fully backed up so I did it quick-and-dirty). Other than loosing terrain data refs. and current shape/clothing/attachment data (easily restored in-sim) all was now good for me.

When installing mono or libgdiplus0 you may get dependency missing libexif.so.9

This was noticed on Centos5 but may occur on other systems, download ftp://rpmfind.net/linux/conectiva/snapshot/i386/RPMS.extra/libexif9-0.5.12-47547cl.i386.rpm and install problem solved. You will now be able to install mono (as long as nothing else goes wrong )

The assembly mscorlib.dll was not found or could not be loaded

This indicates that you are missing one of the mscor libs that comes with nant. This is easily solved by getting NAnt, which comes with both versions 1.0 and 2.0 of the required lib.

apt-get install nant

External Program Failed: /usr/lib/pkgconfig/../../lib/mono/2.0/gmcs.exe

This is quickly fixed by retrieving mono-gmcs.

apt-get install mono-gmcs

The type or namespace name JScript does not exist in the namespace Microsoft

Note that it says JScript over and over again. Hint perhaps?

apt-get install mono-mjs libmono-microsoft8.0-cil

On Fedora and OpenSUSE, the needed package is "mono-jscript".

The type or namespace name Tcp does not exist in the namespace System.Runtime.Remoting.Channels

This one is taken care of with a quick install:

apt-get install libmono-system-runtime2.0-cil

Missing: libopenjpeg-libsl-2.1.2.0-x86_64.so

You are probably on a 64-bit linux machine and may need to follow these instructions:

• Installing and running on x86-64

error while loading shared libraries: libgthread-2.0.so.0: cannot open shared object file

If you start with a base Debian system as we did at the top of the page, but instead of using the apt version of mono you use the installer from their website, then you may encounter this issue.

After getting the .bin file from http://www.mono-project.com/Downloads, and executing it as per its instructions, upon finishing, you may find that if you try to run `mono --version` you are presented with this message. This one means you need to install libglib2.0-0.

apt-get install libglib2.0-0

The current runtime framework 'mono-2.0' is not correctly configured in the NAnt configuration file.

This one seems to be fixed by retrieving the apt version of nant.

apt-get install nant

This can also be due to pkg-config not being able to locate the mono.pc file. Adding the directory containing this file to the environment variable PKG_CONFIG_PATH may solve this.

Networking and config issues

See also the wiki page:

• Network Settings
• Configuration

You are able to log in, but not connect to a Region from a remote client

Look in your OpenSimulator/bin/Regions folder:

In 0.6.7 or later,

1. Try 0.0.0.0 for the InternalAddress in your Regions.ini file.
2. ExternalHostName=127.0.0.1 will be needed to change its name to the asscssable DNS name such as "opensim.example-host.com" or "71.6.131.152" (your public accessable ip)

In 0.6.6 or earlier,

1. Try 0.0.0.0 for the internal_ip_address in your region.xml(default.xml) file.
   (you'll have one of these files for each region you have created)
2. external_host_name="127.0.0.1" will be needed to change its name to the accessable DNS name such as "opensim.example-host.com" or "71.6.131.152" (your public accessable ip)

Building OpenSim

I can't find any build files or solution files

• If you're on Windows, run

runprebuild.bat

• on Linux/Mac/FreeBSD, run

runprebuild.sh

VS2005 won't open the .sln file

• Try running VS2005 C#. You are probably running VS2005 C++. This is a C# project.

Running OpenSim

Running OpenSim.exe from a Cygwin shell has access denied for some dll's

• Do a 'cd bin' followed by 'chmod a+x *' to make all dll files executable.

How to do a clean rebuild? (e.g. after 'APPLICATION EXCEPTION DETECTED' after rebuild with updated source)

When you build from source, then update the source, rebuild and try to run, you may sometimes get strange runtime exceptions, usually along the lines of APPLICATION EXCEPTION DETECTED: System.UnhandledExceptionEventArgs, Exception: System.MissingMethodException

Freshly obsolete files still present on your system can cause this problem.

See Troubleshooting:Old Dlls

Something Has Gone Wrong!

I get errors concerning 'owner_uuid' when starting up my grid after updating from svn beyond r3254

When updating to recent revisions after r3254, we are now using the unused owner_uuid. There are some grids whose mysql tables were created during a time when this field was inadvertently removed from the .sql script that initializes the regions table. Logging in to your mysql instance and executing this SQL query to add the missing owner_uuid should solve this issue:

alter table `regions` add column `owner_uuid` varchar(36) default '00000000-0000-0000-0000-000000000000' not null, comment 'Rev.2';

The punctuation around regions and owner_uuid is "grave accent". The punctuation around the default value and the comment is the single quote. The "grave accent" is the one generally to the left of the One button, under the tilde and the single-quote, is, well, underneath the double quote. I think this matters to mysql.

I get errors concerning 'State' when starting up my grid after updating from svn beyond r3786

After r3786, a new 'State' field has been added to the 'primshapes' table on SQLite. This field is used to persist trees and grass. You may have an empty region at startup, because OpenSim does not find this 'State' field and does not know what to do. The best is to use SQLiteBrowser or another SQLite table editor (download it at http://sqlitebrowser.sourceforge.net/) to create the missing field:

alter table primshapes add column State integer default 0

Just launch SQLiteBrowser, use File/Open database, then browse to OpenSim.db file and open it. Then, go to the "Execute SQL" tab, copy/paste the command above in the "SQL string" textbox, then hit the "Execute query" button.

I get a timeout during region handshake

• Do you have the correct IP in your Regions\* config files?
• Do you have multiple interfaces on the server running OpenSim? OpenSim will not bind outgoing UDP packets to a specific IP, its default IP to reach you will be what the Region answers UDP with. If you have configured the region for another IP you will get a timeout during connect.

I cannot connect to my OpenSim

• See OpenSim: Connecting

I can connect but cannot move

If the client connects but the avatar can only spin in place and not move, then the sim is not correctly configured. It completed the initial login function, but packets are not being exchanged between the client and the sim, probably due to a network configuration error on the sim.

• See OpenSim: Configuration

From time to time my Avatar seems to get stuck

Right now there is a bottle neck when syncing prims off to the database. This will cause small (5 - 10 second) apparent hangs of the Avatar, but it will recover fine once the data is synced. It is a known issue based on legacy architecture of some of the data storage code. We hope this will be removed soon.

I have problems with viewing the worldmap

• This may happen when running OpenSim on a Linux server, both in grid or standalone mode.
• Symptoms: when opening the worldmap window in the SL-viewer, the sims are not displayed grahically in the worldmap, the server console shows some error related to openjpeg, the current session freezes...
• Reason: your svn source trunk does not have the correct (or whatever...) libopenjpeg-libsl library.
• Other reason: the file "defaultstripe.png" does not exists in the same OpenSim folder, or is corrupted.
• Solution: get the newest code from libsecondlife (svn co svn://opensecondlife.org/libsl/trunk), 'make' manually in the subdir openjpeg-libsl, and copy the resulting libopenjpeg-libsl-2.1.2.0.so into your OpenSim bin subdir, overwriting the existing one.
• Recompile & restart OpenSim

Exceptions on the Console

This is a list of Exceptions that you may see on the console, what they mean, and if they are a problem.

System.DllNotFoundException: ./libopenjpeg-libsl-2.1.2.0.so

You are on Linux, and the native lib libopenjpeg-libsl-2.1.2.0.so is not compatible with your system for one of the following reasons:

• You have an old processor (libopenjpeg has been compiled with optimizations)
• You are running in 64bit mode (none of the native libs are built for 64bit)

You can rebuild your own libopenjpeg from source, or run in a compatible environment. You can do this by:

svn co svn://openmv.org/libsl/libopenmetaverse/trunk libsl
cd libsl/openjpeg-libsl/
make

then copy libopenjpeg-libsl-2.1.2.0.so into OpenSim bin-folder.

System.NullReferenceException at OpenSim.Region.Communications.Local.LocalLoginService.PrepareLoginToRegion

Your first startup of OpenSim has failed for example due to giving non existent domain name when prompted for region external host name. This causes only partial initialization. You need to delete bin folder, do svn update, rebuild and purge database to resolve this issue.

Exception: System.NotImplementedException: The requested feature is not implemented.

If your exception starts as follows:

 at (wrapper managed-to-native) System.Threading.Interlocked:Add (int&,int)
 at System.Threading.ReaderWriterLockSlim.TryEnterReadLock (Int32 millisecondsTimeout) [0x000e3] in

You probably unwittingly passed the option --optimize=-all to mono. The problem is that Mono compiles in an "optimized" version of the System.Threading.Interlocked class's methods; these optimizations are done using raw assembler for your architecture (automatically detected at build time). When you pass --optimize=-all, the runtime detects that these functions are optimized, and disables them. So the next time a class tries to call these functions, the runtime finds that there is no native implementation of the methods! This affects almost all synchronization primitives System.Threading. Since OpenSimulator relies heavily on threading and locking mechanisms, we can't do without this functionality. Perhaps a future Mono version will allow you to pass --optimize=-all, and provide an unoptimized implementation (e.g. pthreads), rather than throwing an exception.

If you're looking to debug a low level problem with mono (such as an error in native code), passing --optimize=-all is not the way to go about it. Instead, set the environment variable MONO_LOG_LEVEL=debug and run your program with the --debug switch passed to mono. You can also run mono under gdb, just like any other process.

Command error: System.IO.FileNotFoundException: Could not load file or assembly 'System.Core, Version=3.5.0.0, culture=neutral,PublicKeyToken=b77a5c561934e089' or one of its dependencies.

A missing System.Core indicates that you are using an old version of the .NET Runtime.

You must use .NET 3.5 or later. .NET 2.0 doesn't have a System.Core.

If you are using Windows .NET, simply download the 3.5 or 4 Update.
If you are using Mono, you'll need to update your mono version.

Grid Mode

I start the sim and it doesn't connect to any grid

When OpenSim is first started, it needs configuration.

• See OpenSim: Configuration.

My grid works fine with one user but when two users login in the same time both get stuck

• Make sure you have export MONO_THREADS_PER_CPU="100" in your environment

After ~20 minutes my region starts to take 100% cpu and region(s) hang

• If you have mono 1.9.1 or lower upgrade to mono 2.2.

Hypergrid

After starting OpenSim with Hypergrid enabled my inventory wont load!

• If you're running in grid mode, first check your OpenSim.ini to make sure that the dns names or addresses for your grid servers are accessible to both you and the public.
• Check the XML config files for your UGAIM servers to make sure that everything is running off of a publicly accessible IP address.
  • If this is the case and you have to change your UGAIM addresses you will need to run a few quick and dirty SQL queries on your database in order to update your grid's user accounts so that they now point to the new IP addresses of your UGAIM.

Log into your sql server and change over to the database for your grid. The following will update your user's home inventory and asset URIs after changing the addresses of your UGAIM services in the XML configuration files.

     update users set userInventoryURI="http://new.UGAIM.address:8004" where userInventoryURI = "http://old.UGAIM.address:8004";

     update users set userAssetURI="http://new.UGAIM.address:8003" where userAssetURI = "http://old.UGAIM.address:8003";

• If you're running in standalone mode... - Anyone familiar with standalone want to fill this in? -

ScriptEngine Issues

Got "Primitive: Error compiling script: unknown char: . error" when compiling script

When trying to compile a script ( using DotNetEngine or XEngine ) you could have this error :

And on the console :

This happens on linux when your locales are not set to default ( "C" ).

• You could refer to Mantis #2088 and Mantis #2015 for a workaround to run opensim.

env LANG=C mono --debug OpenSim.exe

• You could also change your locale setup. Here is what I use in my '.bash_profile' :

export LC_ALL=C
export LANG=C

I know it's a ugly way to setup locales on a linux box, but it works fine on my Linux From Scratch box.

Rq: I saw Melanie has corrected some parts of the source code a few weeks ago to avoid such problems.

Get "Primitive: Error compiling script: ApplicationName='gmcs', ..." when compiling script

When trying to compile a script ( using DotNetEngine or XEngine ) you have an error something like :

Other features include "Touch" being disabled on the right click menu wheel.

You might have a broken mono install (i.e. discovered as mono but not gmcs installed on a Ubuntu 8.10 Intrepid machine.)

Check mono-gmcs (sudo apt-get install mono-gmcs) is correctly installed.

Locales Issues

Well, some of us, OpenSim users, ran into random crash of the OpenSim Region server in grid mode ...

I have made many tests to find a solution about that problem.

I first ran into this problem with OpenSIM SVN.6660 ... Even if I have no users connected, my OpenSim region server randomly crash ( after 1 hour, or 5 hours, ... ).

My first idea was to upgrade to the latest SVN release, no chance, same problem. So I made a test with a previous SVN release ( SVN.6575 ) which is running fine on another server ( same OS, same parameters, same mono release, ... ) : No chance, same problem.

Then, I tried to play with locales, recompile the screen unix command line utility I use to run my servers, ... No chance again.

So, I checked the memory usage on my Server, and I discovered that with the last SVN release, the amount of memory needed to run OpenSim server in multi-region/grid mode increased :) ... So, I have tuned my MySQL server to use less memory. Was better, but my OpenSim region server still randomly crash ( but could stay alive longer than before ).

Then, trying to play with the screen command line options ... And all my tests shows that the --debug option impact the stability of the server.

Initially, I used such command line to run OpenSim :

/screen -S Region-service -d -m --debug mono OpenSim.exe

Without the --debug option, everything seems to be more stable.

About locales, if you read mantis and threads in opensim-dev / opensim-users, you know that there are issues on system that are not "en_US" or "C" local compliant.

I have re-setup my server to be full "en_US.UTF8".

On my Ubuntu 8.0.4 server :

# cat /etc/default/locale
LANG="en_US.UTF-8"

# cat /var/lib/locales/supported.d/local
fr_FR.UTF-8 UTF-8
en_US.UTF-8 UTF-8

# cat /etc/environment
PATH="/usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/sbin:/bin:/usr/games"
LANG="en_US"
LANGUAGE="en_US"

And maybe you should need :

# sudo dpkg-reconfigure locales

So, the resulting screen command line options should be :

screen -S Region-service -d -m -U mono OpenSim.exe

This allow me to run OpenSim SVN.6575 without crash during more than 48 hours, and also SVN.6735 ...

Hope those informations could help peoples.

Just for your information :

Here is my OpenSim Startup script :

#!/bin/bash

echo "User-Service..."
/usr/local/bin/screen -S User-service -d -m -U mono OpenSim.Grid.UserServer.exe
