As 'dwheele' ran

svnadmin create /home/dwheele/my-repos

This created the repository, but I couldn't connect to it from my workstation.

Needed to open up port 3690 on the StopsToGo droplet. So I used this

sudo ufw allow 3690
sudo ufw disable
sudo ufw enable
sudo ufw status

This uses the UFW (Uncomplicated Firewall) functionality which internally modifies iptables.

Had problem when using the client because I needed to use svn://stopstogo.com/home/dwheele/my-repos
