Hi there, I've seen the zero KB file issue when there are firewall issues. Specifically, it looks like you have traffic allow one direction but not the other.
It may be working between EC2 instances due to them being in the same zone, and traffic is handled differently than for outside requests. Did you add all the ports explicitly in your EC2 Security Groups inbound connections configuration? I think this is most likely the issue. You might also install iptraf on the Ubuntu side and run that while connecting from both the other EC2 instance and from OSX to further identify if connections are being made.
