Top Forums UNIX for Advanced & Expert Users Permissions on a directory in /home for all users Post 302921856 by cjcox on Monday 20th of October 2014 02:48:20 PM

Make every user that is sharing a member of a group, example "shared"

Then change the group ownership of the shared home area to "shared" and make it group writable and change the sticky bit.

Then ensure all access using a umask 0002 (some clients will try to preserve client side perms, so make sure files, etc. on the client side have group write perms.... an example is sftp, if the client file isn't grouip writable, neither will the remote side when copied).

Code:
mkdir /home/shared
chgrp shared /home/shared
chmod u+rwx,g+rwxs /home/shared

In order to bypass normal operations and "fix" the bits for any file operation, you'll need an extra level of abstraction to the filesystem (unless somebody knows of something).

NAME
pkcsslotd - shared memory manager for opencryptoki DESCRIPTION
The pkcsslotd daemon manages PKCS#11 objects between PKCS#11-enabled applications. When 2 or more processes are accessing the same crypto- graphic token, the daemon is notified and updates each application when the token's objects change. NOTES
Only one instance of the pkcsslotd daemon should be running on any given host. If a prior instance of pkcsslotd did not shut down cleanly, then it may leave an allocated shared memory segment on the system. The allocated memory segment can be identified by its key and can be safely removed once the daemon is stopped with the ipcrm command, such as: ipcrm -M 0x6202AB38 The daemon creates the shared memory segment with group ownership by the pkcs11 group. All non-root users that should be able to use open- Cryptoki need to be members of the group. Only trusted users should be assigned to the group, see the "SECURITY NOTE" in the opencryp- toki(7) manual page for details. SEE ALSO
opencryptoki(7), pkcsconf(1), pk_config_data(5), pkcs11_startup(1). 3.0 May 2007 PKCSSLOTD(8)
