This SMB allows a client to tell a server to "watch" a particular directory for any changes and only reply to the SMB request when a change has occurred. Such constant scanning of a directory is expensive under UNIX, hence an smbd 8 daemon only performs such a scan on each requested directory once every change notify timeout seconds. Default: change notify timeout = 60 Example: change notify timeout = 300 Would change the scan time to every 5 minutes.
