I start the sim and it doesn't connect

When OpenSim is first started, it needs configuration.

I start the OpenSim.Grid.UserServer.exe and it errors

If this error is access denied for username@localhost, the mysql database is not set up.

It will print some text and wait for input - either an enter to accept a default value, or another value you can supply.

I want to run my own Local Grid but one or more servers fail to start

• Be sure that you're able to start OpenSim.exe alone, in Standalone mode, and to be able to login.
• Start the servers in the correct UGAS order and answer the questions as recommended (see OpenSim: Configuration).
• Set all the external URI's to the correct IP: 127.0.0.1 if running on your local machine, or aaa.bbb.ccc.ddd if running on a remote server.
• Check again all the *.xml configuration files for any wrong settings or typing errors...!
• Don't forget to connect with your SL-viewer to port 8002 (Grid User-Server) instead of 9000 (Standalone OpenSim-Server).
• Delete all *.xml and *.yap files in the bin directory if you want to run a full reconfiguration again.

I cannot connect to my OpenSim

• See OpenSim: Connecting.

I 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.
