[Zope] Initial setup

I'm setting up ZOPE on a remote Red Hat system for the first time and am not clear about a couple of things involving how to run it... How do I identify which version is running? I presume I use zopectl to start it - my Zope Bible tells me to run ./start which I can't find. How do I stop it? It looks like I didn't set up the initial user correctly so can't use the ZMI. -- John
