Some friends and I have been experimenting with NINJAM over the past couple of weeks and it got to the point where I wanted to run my own NINJAM server, rather than relying on the public servers or Jan Bucholtz’s. if you want to find out more about NINJAM there is a good overview at http://www.cockos.com/ninjam/.
It turned out to be relatively easy, although took a little bit of tinkering.
Download the NINJAM server source code from http://www.cockos.com/ninjam/downloads/src/ninjam_server_0.06.tar.gz
I then needed to make sure I had the software installed to be able to compile the application:
“sudo apt-get install build-essential”
I unpacked the source code:
“tar xvzf ninjam_server_0.06.tar.gz”
Change into the directory where the ninjamsvr.cpp code resides. In my case this was:
Compile the code
Take a copy of the example configuration file
“cp example.cfg myconfig.cfg”
After making some changes to the well documented config file you can start the server application by typing;
I needed to amend my router’s port forwarding to make sure the server was visible to the outside world and that was it.
I’ve chosen to secure my ninjam server with userid/passwords, rather than leave it open to anonymous users. If you want to have a go at a NINJAM sometime, or just to borrow the server for your own test, let me know and I’ll set up a password for you.
Another point worthy of note – because NINJAM relies on a repeating sequence of chords to sync up everyone’s parts, it is important to get the number of bars set correctly. After experimentation I found that if you multiply the number of bars required by four you get the value at which to set the BPI. Therefore, for a 12 bar progression set the BPI to 48.
