Using Terrain commands by example
Quickly flatten a region
When you have multiple regions, that you need to terraform to a certain height, the quickest way to do it is by selecting a region, and fill the terrain to the specified height:
change-region YourRegionName terrain fill 20
Note: Remember to change to the region you wish to modify if that is the only region wish to make changes to. Without using the change-region command, you may very well end up flattening multiple regions!
Running Squid on your region server as a reverse proxy to the asset server
1. Download and install the Squid Proxy from: http://www.squid-cache.org/Download/
2. Create your squid.conf configuration file.
3. Change your asset_server configuration in your OpenSim.ini to point to http://localhost:3128/
4. Start everything up!
Now assets will be cached in the squid cache on the region server, and will be served up much faster, especially on region restart.
