bitnami SVN UNIX to EC2

I was able to get my bitnami SVN repository working, and I can sync up my Windows PC with my repo and check in files using Eclipse which all works well. I also have some code on a separate UNIX server that I would like to include in my source control. Are there any instructions on what I need to make this connection?

I have:

1. Installed subversion on my other EC2 with sudo apt-get install subversion (is this necessary?)
2. Opened up ports 22 and 3690 to the new EC2 IP
3. Tried to checkout a file with: svn checkout svn://ec2-##-###-##-###.compute-1.amazonaws.com/trunk/path/to/file/file.txt. This just times out
4. Repeated step 3 with svn+ssh instead of svn

I just can't seem to make the connection. What am I missing?
