Hi Wayne,
What is the version of ColdFusion you are using? ColdFusion is not yet supported on Ubuntu 13.10. It's great 
, that it is working for you.
You may refer to http://help.adobe.com/en_US/ColdFusion/10.0/Developing/index.html and http://blogs.coldfusion.com/post.cfm/getting-started-with-tomcat-in-co ldfusion-10.
If you are able to access CF Admin, that means, CF engine is working on your server. Is there any specific code/file not working for you?
Regards
Anit Kumar
