       smbcquotas {//server/share} [-u|--user user] [-L|--list] [-F|--fs]

       This tool is part of the samba(7) suite.

       The smbcquotas program manipulates NT Quotas on SMB file shares.

       The following options are available to the smbcquotas program.

       -u|--user user
           Specifies the user of whom the quotas are get or set. By default
           the current user's username will be used.

           Lists all quota records of the share.

           Show the share quota status and default limits.

       -S|--set QUOTA_SET_COMMAND
           This command sets/modifies quotas for a user or on the share,
           depending on the QUOTA_SET_COMMAND parameter which is described

           This option displays all QUOTA information in numeric format. The
           default is to convert SIDs to names and QUOTA limits to a readable
           string format.

       -m|--max-protocol PROTOCOL_NAME
           This allows the user to select the highest SMB protocol level that
           smbcquotas will use to connect to the server. By default this is
           set to NT1, which is the highest available SMB1 protocol. To
           connect using SMB2 or SMB3 protocol, use the strings SMB2 or SMB3

           Don't actually do anything, only validate the correctness of the

           Be verbose.

           level is an integer from 0 to 10. The default value if this
           parameter is not specified is 0.

           The higher this value, the more detail will be logged to the log
           files about the activities of the server. At level 0, only critical
           errors and serious warnings will be logged. Level 1 is a reasonable
           level for day-to-day running - it generates a small amount of
           information about operations carried out.

           Levels above 1 will generate considerable amounts of log data, and
           should only be used when investigating a problem. Levels above 3
           are designed for use only by developers and generate HUGE amounts
           of log data, most of which is extremely cryptic.

           Note that specifying this parameter here will override the log
           level parameter in the smb.conf file.

           Prints the program version number.

       -s|--configfile=<configuration file>
           The file specified contains the configuration details required by
           the server. The information in this file includes server-specific
           information such as what printcap file to use, as well as
           descriptions of all the services that the server is to provide. See
           smb.conf for more information. The default configuration file name
           is determined at compile time.

           Base directory name for log/debug files. The extension ".progname"
           will be appended (e.g. log.smbclient, log.smbd, etc...). The log
           file is never removed by the client.

           Set the smb.conf(5) option "<name>" to value "<value>" from the
           command line. This overrides compiled-in defaults and options read
           from the configuration file.

           If specified, this parameter suppresses the normal password prompt
           from the client to the user. This is useful when accessing a
           service that does not require a password.

           Unless a password is specified on the command line or this
           parameter is specified, the client will request a password.

           If a password is specified on the command line and this option is
           also defined the password on the command line will be silently
           ignored and no password will be used.

           Try to authenticate with kerberos. Only useful in an Active
           Directory environment.

           Try to use the credentials cached by winbind.

           This option allows you to specify a file from which to read the
           username and password used in the connection. The format of the
           file is

               username = <value>
               password = <value>
               domain   = <value>

           Make certain that the permissions on the file restrict access from
           unwanted users.

           Sets the SMB username or username and password.

           If %password is not specified, the user will be prompted. The
           client will first check the USER environment variable, then the
           LOGNAME variable and if either exists, the string is uppercased. If
           these environmental variables are not found, the username GUEST is

           A third option is to use a credentials file which contains the
           plaintext of the username and password. This option is mainly
           provided for scripts where the admin does not wish to pass the
           credentials on the command line or via environment variables. If
           this method is used, make certain that the permissions on the file
           restrict access from unwanted users. See the -A for more details.

           Be cautious about including passwords in scripts. Also, on many
           systems the command line of a running process may be seen via the
           ps command. To be safe always allow rpcclient to prompt for a
           password and type it in directly.

       -S|--signing on|off|required
           Set the client signing state.

           Use stored machine account password.

           This command line parameter requires the remote server support the
           UNIX extensions or that the SMB3 protocol has been selected.
           Requests that the connection be encrypted. Negotiates SMB
           encryption using either SMB3 or POSIX extensions via GSSAPI. Uses
           the given credentials for the encryption negotiation (either
           kerberos or NTLMv1/v2 if given domain/username/password triple.
           Fails the connection if encryption cannot be negotiated.

           The supplied password is the NT hash.

           Print a summary of command line options.

           Display brief usage message.

       The format of an the QUOTA_SET_COMMAND is an operation name followed by
       a set of parameters specific to that operation.

       To set user quotas for the user specified by -u or for the current


       To set the default quotas for a share:


       To change the share quota settings:


       All limits are specified as a number of bytes.

       The smbcquotas program sets the exit status depending on the success or
       otherwise of the operations performed. The exit status may be one of
       the following values.

       If the operation succeeded, smbcquotas returns an exit status of 0. If
       smbcquotas couldn't connect to the specified server, or when there was
       an error getting or setting the quota(s), an exit status of 1 is
       returned. If there was an error parsing any command line arguments, an
       exit status of 2 is returned.

       This man page is part of version 4.13.14 of the Samba suite.

       The original Samba software and related utilities were created by
       Andrew Tridgell. Samba is now developed by the Samba Team as an Open
       Source project similar to the way the Linux kernel is developed.

       smbcquotas was written by Stefan Metzmacher.
