gentest - Man Page

Run random generic SMB operations against two SMB servers and show the differences in behavior


gentest {//server1/share1} {//server2/share2} {-U user%pass} {-U user%pass} [-s seed] [-o numops] [-a] [-A] [-i FILE] [-O] [-S FILE] [-L] [-F] [-C] [-X]


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.

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


-U user%pass

Specify the user and password to use when logging on on the shares. This parameter is mandatory and has to be specified twice.

-s seed

Seed the random number generator with the specified value.

-o numops

Set the number of operations to perform.


Print the operations that are performed.


Backtrack to find minimal number of operations required to make the response to a certain call differ.


Specify a file containing the names of fields that have to be ignored (such as time fields). See below for a description of the file format.


Enable oplocks.


Set preset seeds file. The default is gentest_seeds.dat.


Use preset seeds


Fast reconnect (just close files)


Continuous analysis mode


Analyse even when the test succeeded.
