SRAS -- An Asset Server for OpenSimulator


Hi. I haven't used OpenSim for over 3 years, and I'm unlikely to update SRAS in the future, so rather than keep it lingering as a project of unknown compatibility with current versions of OpenSim I'm just going to officially declare SRAS abandonware.

I wrote the first version in an afternoon back in 2010, and it was only supposed to be a stop-gap measure for "2 or 3 weeks". Hopefully today there are better, more up-to-date options available to you.

Thanks for your support.

  • Asset de-duplication
  • Compressed asset storage on disk
  • Ability to disable serving of specific assets without deleting


The packages of Ruby shipping with Ubuntu don't include built-in zlib support. I prefer using RVM [ ] anyway.

Built & tested with Ruby v1.9.2.

Install via:

$ gem install sras

then copy the following text into /etc/sras/sras.conf or ~/.srasrc and edit as appropriate: ::

        default_asset_dir: /srv/sras
        port: 8003
        log_file: /var/log/sras.log
        pid_file: /tmp/

        adapter: mysql
        host: localhost
        username: sras
        password: sras
        database: sras


Then just:

$ sras start

to start a single instance. In a production environment you would likely want to run several instances behind a reverse proxy like Nginx.

To see additional options:

$ sras --help


To test asset creation:

$ curl -d @test/test.asset -X POST -w '%{http_code}\n' \

You should get a 200 HTTP response, have an entry in your assets table, and have a file contain the asset data on disk.

To test retrieval of that asset:

$ curl -X GET -w '%{http_code}\n' \
