this might be off-topic, but it may as well be a zope error - I don't know. I have a Samba-share mounted and a Zope External Method which is supposed to store files on this share. The zope user has write access to the share, because if I do a "su - www-data" I can create and delete files there. Python makes no problems, either. A test script, run with the uid of the zope user, can also create and delete files there. Now if I embed this really simple code in my External Method, I get an "IOError: Permission denied" from Zope: fh = open('/BETA/test.txt','w') # BETA is the mounted share fh.write('Eat this\n') fh.close Any ideas? I've really tried everything that came to my mind, but I require that samba share to be written to (no nfs!)... Thanks in advance, Heiko -- Heiko Stoermer MIG Augsburg
