Hi, I'm not sure if its in the docs, but the Linux binary install knows too much ... After the tar xvfz it creates the Zope directory with owner 506.users. As I'll run my installation along side apache, I ran the install script unde root, then did a "chown -R nobody.nobody var" so Zope will start. At this point I did a test and all was well. Next I installed five packages in no particular order (GenericUserFolder-alpha1.tgz, TinyTableB2.tgz, poll-0.6.3.tgz, Squishdot-0-3-2.tgz, ZDiscussions-0.1.0.tgz)and restarted Zope. It worked, but there were lots of authentication and/or file access problems that prevented me entering the manage screen. I fixed the problem with these commands ... chown root.root Zope-2.1.0b1-linux2-x86 cd Zope-2.1.0b1-linux2-x86 chown -R root.root * chown -R nobody.nobody var It was almost certainly one of the packages which tripped the whole thing up, but there is certainly a problem in that the tarball will extract to a funny owner, and post-install, the owners are a real mess.
