<grep -i -l Sandstorm /etc/*> lists only the /etc/hosts file. <grep -i -l Linuxbox /etc/*> lists /etc/hostname and /etc/motd. I changed the /etc/hosts file so that the localhost is now Linuxbox, ran <hostname -F /etc/hosthame> and now I am able to ping Linuxbox. Kent, you said there might be more files. Did I miss them?
