NAME
vfs_readonly - make a Samba share read only for a specified time period SYNOPSIS
vfs objects = readonly DESCRIPTION
This VFS module is part of the samba(7) suite. The vfs_readonly VFS module marks a share as read only for all clients connecting within the configured time period. Clients connecting during this time will be denied write access to all files in the share, irrespective of ther actual access privileges. This module is stackable. OPTIONS
readonly:period = BEGIN, END Only mark the share as read only if the client connection was made between the times marked by the BEGIN and END date specifiers. The syntax of these date specifiers is the same as that accepted by the -d option of GNU date(1). EXAMPLES
Mark all shares read only: [global] vfs objects = readonly Mark the [backup] share as read only during business hours: [backup] path = /readonly vfs objects = readonly readonly:period = readonly:period = "today 9:00","today 17:00" VERSION
This man page is correct for version 3.0.25 of the Samba suite. AUTHOR
The original Samba software and related utilities were created by Andrew Tridgell. Samba is now developed by the Samba Team as an Open Source project similar to the way the Linux kernel is developed. Samba 3.5 06/18/2010 VFS_READONLY(8)
