DESCRIPTION
This tool is part of the samba(7) suite.
The sharesec program manipulates share permissions on SMB file shares.
OPTIONS
The following options are available to the sharesec program. The format
of ACLs is described in the section ACL FORMAT
-a|--add=ACL
Add the ACEs specified to the ACL list.
-D|--delete
Delete the entire security descriptor.
-F|--force
Force storing the ACL.
-m|--modify=ACL
Modify existing ACEs.
-M|--machine-sid
Initialize the machine SID.
-r|--remove=ACL
Remove ACEs.
-R|--replace=ACLS
Overwrite an existing share permission ACL.
-v|--view
List a share acl
--view-all
List all share acls
-S|--setsddl=STRING
Set security descriptor by providing ACL in SDDL format.
-V|--viewsddl
List a share acl in SDDL format.
-?|--help
Print a summary of command line options.
-d|--debuglevel=level
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.
-V|--version
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.
-l|--log-basename=logdirectory
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.
--option=<name>=<value>
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.
ACL FORMAT
The format of an ACL is one or more ACL entries separated by either
commas or newlines. An ACL entry is one of the following:
REVISION:<revision number>
OWNER:<sid or name>
GROUP:<sid or name>
ACL:<sid or name>:<type>/<flags>/<mask>
The revision of the ACL specifies the internal Windows NT ACL revision
for the security descriptor. If not specified it defaults to 1. Using
values other than 1 may cause strange behaviour.
The owner and group specify the owner and group SIDs for the object.
Share ACLs do not specify an owner or a group, so these fields are
empty.
ACLs specify permissions granted to the SID. This SID can be specified
in S-1-x-y-z format or as a name in which case it is resolved against
the server on which the file or directory resides. The type, flags and
mask values determine the type of access granted to the SID.
The type can be either ALLOWED or DENIED to allow/deny access to the
SID. The flags values are generally zero for share ACLs.
The mask is a value which expresses the access right granted to the
SID. It can be given as a decimal or hexadecimal value, or by using one
of the following text strings which map to the NT file permissions of
the same name.
o R - Allow read access
o W - Allow write access
o X - Execute permission on the object
o D - Delete the object
o P - Change permissions
o O - Take ownership
The following combined permissions can be specified:
o READ - Equivalent to 'RX' permissions
o CHANGE - Equivalent to 'RXWD' permissions
o FULL - Equivalent to 'RWXDPO' permissions
EXIT STATUS
The sharesec 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, sharesec returns and exit status of 0. If
sharesec couldn't connect to the specified server, or there was an
error getting or setting the ACLs, an exit status of 1 is returned. If
there was an error parsing any command line arguments, an exit status
of 2 is returned.
EXAMPLES
Add full access for SID S-1-5-21-1866488690-1365729215-3963860297-17724
on share:
host:~ # sharesec share -a S-1-5-21-1866488690-1365729215-3963860297-17724:ALLOWED/0/FULL
List all ACEs for share:
host:~ # sharesec share -v
REVISION:1
CONTROL:SR|DP
OWNER:
GROUP:
ACL:S-1-1-0:ALLOWED/0x0/FULL
ACL:S-1-5-21-1866488690-1365729215-3963860297-17724:ALLOWED/0x0/FULL
