Here is what I tried. I logged in as root (no password) and from the command prompt typed "passwd" this walked me through settings up a password, which I assume was for the root user. Next I rebooted. This time when I entered a username of "root" it asked me for a password, which I entered and logged in.
Yet still, I am unable to SSH from another computer:
$ ssh root@192.168.11.5
ssh: connect to host 192.168.11.5 port 22: Connection refused
