;******************************************************************************
; File to define cifsd configuration parameters which are comparable with
; samba's ones
;
; Supported [global] level parameters list:
; - server string
; This controls what string will show up in browse lists next
; to the machine name
; - workgroup
; This controls what workgroup your server will appear to be
; in when queried by clients
; - netbios name
; This sets the NetBIOS name by which a SMB server is known.
; By default it is the same as the first component of the host's
; DNS name. If a machine is a browse server or logon server this
; name (or the first component of the hosts DNS name) will be
; the name that these services are advertised under.
; - server min protocol
; This setting controls the minimum protocol version that the
; server will allow the client to use.
; - server max protocol
; The value of the parameter (a string) is the highest protocol
; level that will be supported by the server.
; - server signing
; This controls whether the client is allowed or required to use
; SMB1 and SMB2 signing. Possible values are default, auto,
; mandatory and disabled.
; - guest account
; This is a username which will be used for access to services
; which are specified as guest ok.
; - max active sessions
; This option allows the number of simultaneous connections to
; a service to be limited.
; - ipc timeout
; This option specifies the number of seconds server will wait
; for the userspace to reply to heartbeat frames. If user space
; is down for more than `ipc timeout` seconds the server will
; reset itself - close all sessions and all TCP connections.
; - restrict anonymous
; The setting of this parameter determines whether user and
; group list information is returned for an anonymous connection.
; - map to guest
; This parameter can take four different values, which tell cifsd
; what to do with user login requests.(bad user
; - bind interfaces only
; This global parameter allows the cifsd admin to limit what
; interfaces on a machine will serve SMB requests.
; - interfaces
; This option allows you to override the default network
; interfaces list that cifsd will use for browsing. The option
; takes only list of interface name.
; - deadtime
; The value of the parameter (a decimal integer) represents
; the number of minutes of inactivity before a connection is
; considered dead, and it is disconnected. The deadtime only
; takes effect if the number of open files is zero.
;
; Supported [share] level parameters list:
; - comment
; comment string to associate with the new share
; - path
; This parameter specifies a directory to which the user of the
; service is to be given access.
; - guest ok
; If this parameter is yes for a service, then no password is
; required to connect to the service.
; - read only
; If this parameter is yes, then users of a service may not
; create or modify files in the service's directory.
; - browseable
; This controls whether this share is seen in the list of
; available shares in a net view and in the browse list.
; - write ok
; - writeable
; Inverted synonym for read only.
; - store dos attributes
; If this parameter is set cifsd attempts to first read DOS
; attributes (SYSTEM, HIDDEN, ARCHIVE or READ-ONLY) from a
; filesystem extended attribute, before mapping DOS attributes
; to UNIX permission bits (such as occurs with map hidden and
; map readonly).
; - oplocks
; This boolean option tells cifsd whether to issue oplocks
; (opportunistic locks) to file open requests on this share.
; - create mask
; When a file is created, the necessary permissions are calculated
; according to the mapping from DOS modes to UNIX permissions, and
; the resulting UNIX mode is then bit-wise 'AND'ed with this
; parameter.
; - directory mask
; This parameter is the octal modes which are used when converting
; DOS modes to UNIX modes when creating UNIX directories.
; - force group
; This specifies a UNIX group name that will be assigned as
; the default primary group for all users connecting to this
; service.
; - force user
; This specifies a UNIX user name that will be assigned as
; the default user for all users connecting to this service.
; - hide dot files
; This is a boolean parameter that controls whether files starting
; with a dot appear as hidden files.
; - hosts allow
; This parameter is a comma, space, or tab delimited set of hosts
; which are permitted to access a service
; - hosts deny
; The opposite of allow hosts - hosts listed here are NOT
; permitted access to services unless the specific services have
; their own lists to override this one. Where the lists conflict,
; the allow list takes precedence.
; - valid users
; This is a list of users that should be allowed to login to this
; service
; - invalid users
; This is a list of users that should not be allowed to login to
; this service.
; - read list
; This is a list of users that are given read-only access to
; a service.
; - write list
; This is a list of users that are given read-write access to
; a service.
; - max connections
; This option allows the number of simultaneous connections to
; a service to be limited.
; - veto files
; This is a list of files and directories that are neither visible
; nor accessible.
;
; Veto any files containing the word Security,
; any ending in .tmp, and any directory containing the
; word root.
; veto files = /*Security*/*.tmp/*root*/
;
; Veto the Apple specific files that a NetAtalk server
; creates.
; veto files = /.AppleDouble/.bin/.AppleDesktop/Network Trash Folder/
;
;
; Rules to update this file:
; - Every [share] definition should start on new line
; - Every parameter should be indented with single tab
; - There should be single spaces around equal (eg: " = ")
; - Multiple parameters should be separated with comma
; eg: "invalid users = usr1,usr2,usr3"
;
; Make sure to configure the server after making changes to this file.
