If there's a 500 error in the trace or access log, there should be something in your error_log too. Traceback please? > 2) I can reach both through the ftp server but transfer rate is > ridiculous (1.7Kb/sec) for a University lan. Very poor speed with blobs is a known problem with zope's built-in FTP server. Almost nobody ever spends any time improving zope's FTP support, since so many of us never use it :-\ 2.7.0 is getting quite old, so you might do well to look at the changelog for more recent versions of zope and see if there's any FTP-related improvements in there. I haven't been paying attention to that. > 3) Even if I could find out why ftp transfer is so slow and sort it, I > seem unable to grant a non-manager read access to a LocalFS object: > the properties don't stick when I change them, LocalFS doesn't support properties at all AFAIK. > and Zope creates the > link to the local directory with user Zope, group Zope, permissions > 660, hence although managers can reach the files, nothing is reachable > for an 'anonymous' user (I created a special user for ftp and gave > only access to the specific directories, before you voice concerns!) You're talking about Zope permissions and filesystem permissions in the same sentence, and the two have *nothing* to do with each other, so I can't quite parse the above. -- Paul Winkler http://www.slinkp.com _______________________________________________ Zope maillist - Zope@zope.org http://mail.zope.org/mailman/listinfo/zope ** No cross posts or HTML encoding! ** (Related lists - http://mail.zope.org/mailman/listinfo/zope-announce http://mail.zope.org/mailman/listinfo/zope-dev )
