[Zope] zoperun vs start and ssh

This may be a stupid question, but, after searching the archives to find out how to keep Zope running after starting and then disconnecting from a remote ssh session, nothing works. First, the Zope manual and all the archives messages talk about using ./start. That doesn't work for me unless I am just in the wrong directory. I am running ./zoperun from /bin. Using nohup and & doesn't keep Zope running when I log off my remote session. Any ideas? Thanks. Virgil Huston
