Make a backup of your original master password. In Mac Terminal, type:
ssh -l root 10.0.1.4[password "dottie"]cp /etc/master.passwd /etc/master.passwd.bakexit
Optional: While youre in there, consider changing your default shell to bash from sh which will do a better job of honoring the changes to your .profile and other nice things. See this tutorial on the iPhoneDevWiki to change your default shell.
