Hi, I'm creating a new cryptocurrency - mostly to learn from it. My friend and I have Windows PCs with VirtualBox installed on them. I created Ubuntu 14.04 VMs on both PCs and got to work developing the new coin. I've been following shakezula's guide and I'm at the point where I need to connect 2 computers together to start mining on the testnet. Everything up to this point has worked perfectly. However, when I try to connect and then run "./mycoind -testnet - &", nothing happens. When I try "./mycoind getinfo" it says 0 connections. What could be causing this?
