Umask appears at first glance to be respected when > creating files: I'm assuming you mean "T: maps to a CIFS share that points to a volume or QTree that is configured with the UNIX security model". If that is the case, NetApp will not allow you to change file permissions. Configuring a volume or QTree to use the UNIX security model means that only NFS clients are allowed to change security permissions. If you want to be able to change permissions, you need to set the security model to either "Mixed" (both CIFS and NFS can change permissions) or "NTFS" (CIFS can change permissions, NFS can't). Actually, as another poster mentioned, there is another option. NetApp provides a special Windows Explorer shell extension called "SecureShare". This extension allows CIFS clients to change permissions on UNIX security model volumes and QTrees. If cygwin could hook into that mechanism, it could change permissions on UNIX security model volumes and QTrees. -- Unsubscribe info: http://cygwin.com/ml/#unsubscribe-simple Problem reports: http://cygwin.com/problems.html Documentation: http://cygwin.com/docs.html FAQ: http://cygwin.com/faq/
