Monitor file changed / created events on big FS
Hi all,

The configuration:

We are useing a HP-UX Server with vxfs File System. The files on this server have normally a umask of 022 (owned by a administrative account) users who have write access to certain files get custom ACL entries that add these rights for the specific user.

Now a Samba server is running to make the files accessible from within Windows Clients.

The problem:

It seams that when a user saves a file from the Windows Client through Samba the file looses the special ACL rights (maybee it's recreated) so that the user can not save again (File is owned by an other user)

Second problem is that a new file has to get the correct ACL's. For now we have a cron job that does ACL fixing every 2 hours for that.

The question:

Is it somehoe possible to monitor the file system for new files / changed files so that everytime a file is changed / created the ACL's can directly be fixed?

Unfortunately we have >1 TB of data in millions of files in thousands of directories so that a find or simillar would consume lots of resources and need multiple minutes per run.

An other idea would be to create a file system overlay that would be mounted over the real fs and triggers the events. Does anybody has an example for something like this on HP-UX or any other idea on how to do this? I know that on Linux and also Windows theer are API methods available for these tasks, so it should be on HP-UX too i hope.

Thanks for any sugestions!

pam_umask

PAM_UMASK(8)							 Linux-PAM Manual						      PAM_UMASK(8)

NAME

       pam_umask - PAM module to set the file mode creation mask

SYNOPSIS

       pam_umask.so [debug] [silent] [usergroups] [umask=mask]

DESCRIPTION

       pam_umask is a PAM module to set the file mode creation mask of the current environment. The umask affects the default permissions assigned
       to newly created files.

       The PAM module tries to get the umask value from the following places in the following order:

       o   umask= argument

       o   umask= entry of the users GECOS field

       o   pri= entry of the users GECOS field

       o   ulimit= entry of the users GECOS field

       o   UMASK= entry from /etc/default/login

       o   UMASK entry from /etc/login.defs

OPTIONS

       debug
	   Print debug information.

       silent
	   Don't print informative messages.

       usergroups
	   If the user is not root and the username is the same as primary group name, the umask group bits are set to be the same as owner bits
	   (examples: 022 -> 002, 077 -> 007).

       umask=mask
	   Sets the calling process's file mode creation mask (umask) to mask & 0777. The value is interpreted as Octal.

MODULE TYPES PROVIDED

       Only the session type is provided.

RETURN VALUES

       PAM_SUCCESS
	   The new umask was set successfully.

       PAM_SERVICE_ERR
	   No username was given.

       PAM_USER_UNKNOWN
	   User not known.

EXAMPLES

       Add the following line to /etc/pam.d/login to set the user specific umask at login:

		   session optional pam_umask.so umask=0022
