smbtorture - Run a series of tests against a SMB server

       This utility is part of the Samba[1] suite, which is developed by the global SambaTeam[2].

       smbtorture was written by Andrew Tridgell.

       This manpage was written by Jelmer Vernooij.

       smbtorture is a testsuite that runs several tests against a SMB server. All tests are known to succeed
       against a Windows 2003 server (?). Smbtorture's primary goal is finding differences in implementations of
       the SMB protocol and testing SMB servers.

       Any number of tests can be specified on the command-line. If no tests are specified, all tests are run.

       If no arguments are specified at all, all available options and tests are listed.

   Bindingstringformat
       The binding string format is:

       TRANSPORT:host[flags]

       Where TRANSPORT is either ncacn_np for SMB, ncacn_ip_tcp for RPC/TCP or ncalrpc for local connections.

       'host' is an IP or hostname or netbios name. If the binding string identifies the server side of an
       endpoint, 'host' may be an empty string.

       'flags' can include a SMB pipe name if using the ncacn_np transport or a TCP port number if using the
       ncacn_ip_tcp transport, otherwise they will be auto-determined.

       other recognised flags are:

       sign
           enable ntlmssp signing

       seal
           enable ntlmssp sealing

       connect
           enable rpc connect level auth (auth, but no sign or seal)

       validate
           enable the NDR validator

       print
           enable debugging of the packets

       bigendian
           use bigendian RPC

       padcheck
           check reply data for non-zero pad bytes

       For example, these all connect to the samr pipe:

       •   ncacn_np:myserver

       •   ncacn_np:myserver[samr]

       •   ncacn_np:myserver[\\pipe\\samr]

       •   ncacn_np:myserver[/pipe/samr]

       •   ncacn_np:myserver[samr,sign,print]

       •   ncacn_np:myserver[\\pipe\\samr,sign,seal,bigendian]

       •   ncacn_np:myserver[/pipe/samr,seal,validate]

       •   ncacn_np:

       •   ncacn_np:[/pipe/samr]

       •   ncacn_ip_tcp:myserver

       •   ncacn_ip_tcp:myserver[1024]

       •   ncacn_ip_tcp:myserver[1024,sign,seal]

       •   ncalrpc:

   UNCFormat
       The UNC format is:

       //server/share

       -d debuglevel
           Use the specified Samba debug level. A higher debug level means more output.

       -U user%pass
           Use the specified username/password combination when logging in to a remote server.

       -k
           Use kerberos when authenticating.

       -W workgroup
           Use specified name as our workgroup name.

       -n netbios_name
           Use specified name as our NetBIOS name.

       -O socket_options
           Use specified socket options, equivalent of the smb.conf option “socket options”. See the smb.conf(5)
           manpage for details.

       -m max_protocol
           Specify the maximum SMB dialect that should be used. Possible values are: CORE, COREPLUS, LANMAN1,
           LANMAN2, NT1

       -s seed
           Initialize the randomizer using seed as seed.

       -L
           Use oplocks.

       -X
           Enable dangerous tests. Use with care! This might crash your server...

       -t timelimit
           Specify the NBENCH time limit in seconds. Defaults to 600.

       -p ports
           Specify ports to connect to.

       -c file
           Read NBENCH commands from file instead of from CLIENT.TXT.

       -A
           Show not just OK or FAILED but more detailed output. Used only by DENY test at the moment.

       -C filename
           Load a list of UNC names from the specified filename. Smbtorture instances will connect to a random
           host from this list.

       -N numprocs
           Specify number of smbtorture processes to launch.

       -e num_files
           Number of entries to use in certain tests (such as creating X files) (default: 1000).

       -f max_failures
           Number of failures before aborting a test (default: 1).
