[Zope] off toic, but... ange-ftp only works as unix root

even though I can ftp into zope from unix root and non-root. As unix non-root, ange-ftp asks for password and then hangs emacs. Does respond to C-g. Same zope user in all cases. The obvious problem is some file or port permission, but I'm hoping someone can show me the way instead of me going for another bushwhack. Debian woody, emacs 20.7.2. Any ideas? Bill.
