information on the helper programs can be obtained from the

http://holger123.wordpress.com/smb-traffic-analyzer/
+ Since the VFS module depends on a receiver that is doing something with
+ the data, it is evolving in it's development. Therefore, the module
+ works with different protocol versions, and the receiver has to be able
+ to decode the protocol that is used. The protocol version 1 was
+ introduced to Samba at September 25, 2008. It was a very simple
+ protocol, supporting only a small list of VFS operations, and had
+ several drawbacks. The protocol version 2 is a try to solve the
+ problems version 1 had while at the same time adding new features.

+ The module now can identify itself against the receiver with a sub-release number, where

+ long as both run on the V2.x protocol, the receiver will not crash, even if the module
+ uses features only implemented in the newer subrelease. Ultimativly, if the module uses
+ a new feature from a newer subrelease, and the receiver runs an older protocol, it is just
+ ignoring the functionality. Of course it is best to have both the receiver and the module
+ running the same subrelease of the protocol.
