OpenSim is a BSD Licensed Open Source project to develop a functioning virtual worlds server platform capable of supporting multiple clients and servers in a heterogeneous grid structure. OpenSim is written in C#, and can run under Mono or the Microsoft .NET runtimes.
See the Opensim wiki for more details.
See BUILDING.txt if you downloaded a source distribution and need to build OpenSim before running it.
We recommend that you run OpenSim from a command prompt on Windows in order to capture any errors.
- cd to the
bin/directory where you unpacked OpenSim. - Run
OpenSim.exe.
Now see the "Configuring OpenSim" section.
You will need Mono >= 2.4.2 to run OpenSim. On some Linux distributions, you may need to install additional packages. See Dependencies for more information.
- cd bin
mono OpenSim.exe
Now see the "Configuring OpenSim" section.
When OpenSim starts for the first time, you will be prompted with a series of questions that look something like:
[09-17 03:54:40] DEFAULT REGION CONFIG: Simulator Name [OpenSim Test]:
For all the options except simulator name, you can safely hit enter to accept the default if you want to connect using a client on the same machine or over your local network.
You will then be asked "Do you wish to join an existing estate?" If you're starting OpenSim for the first time, answer no (which is the default) and provide an estate name.
Shortly afterwards, you will be asked to enter an estate owner's first name, last name, password, and e-mail (which can be left blank). Do not forget these details; since initially only this account will be able to manage your region in-world. You can also use these details to perform your first login.
Once you are presented with a prompt that looks like:
Region (My region name) #
You have successfully started OpenSim.
If you want to create another user account to log in rather than the estate account, then type "create user" on the OpenSim console and follow the prompts.
Helpful resources:
By default, your sim will be available for login on port 9000. You can log in by adding -loginuri http://127.0.0.1:9000 to the command that starts Second Life (e.g., in the Target box of the client icon properties on Windows). You can also log in using the network IP address of the machine running OpenSim (e.g., http://192.168.1.2:9000).
To log in, use the avatar details that you gave for your estate ownership or the one you set up using the "create user" command.
If running under Mono: run OpenSim.exe with the --debug flag:
mono --debug OpenSim.exe

Thanks for trying OpenSim; we hope it is a pleasant experience.
