ftp is turned off. Samba, I thought was running but haven't tried to set it
up as I was more interested in just accessing web services, locally.

I can ssh in remotely but don't have a need for it locally. I can access
webmin remotely but not from a local machine. I see no need for my server to
use additional resources for the x window environment. I don't use webmin
that much except when I need to turn a service on or off remotely or want to
upload a file to the server without having to turn of ftp.
