Hello, I have successfully compiled the 3.0.23c smbtorture tool (on Redhat Linux)and have noticed that the NBENCH variation does not seem to be working. I am using the client.txt file available from the 3.0.4 DBENCH package. I am invoking this against IBM's z/OS (MVS) CIFS server from a RedHat Linux client and the command I am using is: ./smbtorture //servername/sharename -U user%pw -L -N2 -c client.txt NBENCH And the failure I receive is: Unknown operation Mkdir Unknown operation Mkdir Is this a known error? The client.txt file I am using is about 26MB in size. Thank you for any assistance! ~Charlie Bryant z/OS CIFS Function Test IBM Corp Endicott, NY USA cjbryant@us.ibm.com
