# [DESCRIPTION](#DESCRIPTION)

.PP gentest is a utility for detecting differences in behaviour between SMB servers. It will run a random set of generic operations against *//server1/share1* and then the same random set against *//server2/share2* and display the differences in the responses it gets.

.PP This utility is used by the Samba team to find differences in behaviour between Samba and Windows servers.
