DESCRIPTION

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

       smbget is a simple utility with wget-like semantics, that can download files from SMB servers. You can
       specify the files you would like to download on the command-line.

       The files should be in the smb-URL standard, e.g. use smb://host/share/file for the UNC path
       \\\\HOST\\SHARE\\file.

OPTIONS

-a, --guest
Work as user guest

-r, --resume
Automatically resume aborted files

--recursive
Recursively download files

-D, --dots
Show dots as progress indication

-o, --outputfile
Write the file that is being downloaded to the specified file. Can not be used together with -R.

--stdout
Write the file that is being downloaded to standard output.

-q, --quiet
Be quiet

-v, --verbose
Be verbose

-b, --blocksize
Number of bytes to download in a block. Defaults to 64000.

-u, --update
Download only when remote file is newer than local file or local file is missing.

-e, --encrypt
Enable SMB encryption.

--limit-rate=INT
Limit download rate by this many KB/s.

-?|--help
Print a summary of command line options.

--usage
Display brief usage message.

-d|--debuglevel=level
level is an integer from 0 to 10. The default value if this parameter is not specified is 1 for
client applications.

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
/etc/samba/smb.conf file.

--debug-stdout
This will redirect debug output to STDOUT. By default all clients are logging to STDERR.

--configfile=<configuration file>
The file specified contains the configuration details required by the client. The information in this
file can be general for client and server or only provide client specific like options such as client
smb encrypt. See /etc/samba/smb.conf for more information. The default configuration file name is
determined at compile time.

--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. If a name or a value includes a
space, wrap whole --option=name=value into quotes.

-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.

--leak-report
Enable talloc leak reporting on exit.

--leak-report-full
Enable full talloc leak reporting on exit.

-V|--version
Prints the program version number.

-R|--name-resolve=NAME-RESOLVE-ORDER
This option is used to determine what naming services and in what order to resolve host names to IP
addresses. The option takes a space-separated string of different name resolution options. The best
is to wrap the whole --name-resolve=NAME-RESOLVE-ORDER into quotes.

The options are: "lmhosts", "host", "wins" and "bcast". They cause names to be resolved as follows:

• lmhosts: Lookup an IP address in the Samba lmhosts file. If the line in lmhosts has no
name type attached to the NetBIOS name (see the lmhosts(5) for details) then any name type
matches for lookup.

• host: Do a standard host name to IP address resolution, using the system /etc/hosts, NIS,
or DNS lookups. This method of name resolution is operating system dependent, for instance
on IRIX or Solaris this may be controlled by the /etc/nsswitch.conf file). Note that this
method is only used if the NetBIOS name type being queried is the 0x20 (server) name type,
otherwise it is ignored.

• wins: Query a name with the IP address listed in the wins server parameter. If no WINS
server has been specified this method will be ignored.

• bcast: Do a broadcast on each of the known local interfaces listed in the interfaces
parameter. This is the least reliable of the name resolution methods as it depends on the
target host being on a locally connected subnet.

If this parameter is not set then the name resolve order defined in the /etc/samba/smb.conf file
parameter (name resolve order) will be used.

The default order is lmhosts, host, wins, bcast. Without this parameter or any entry in the name
resolve order parameter of the /etc/samba/smb.conf file, the name resolution methods will be
attempted in this order.

-O|--socket-options=SOCKETOPTIONS
TCP socket options to set on the client socket. See the socket options parameter in the
/etc/samba/smb.conf manual page for the list of valid options.

-m|--max-protocol=MAXPROTOCOL
The value of the parameter (a string) is the highest protocol level that will be supported by the
client.

Note that specifying this parameter here will override the client max protocol parameter in the
/etc/samba/smb.conf file.

-n|--netbiosname=NETBIOSNAME
This option allows you to override the NetBIOS name that Samba uses for itself. This is identical to
setting the netbios name parameter in the /etc/samba/smb.conf file. However, a command line setting
will take precedence over settings in /etc/samba/smb.conf.

--netbios-scope=SCOPE
This specifies a NetBIOS scope that nmblookup will use to communicate with when generating NetBIOS
names. For details on the use of NetBIOS scopes, see rfc1001.txt and rfc1002.txt. NetBIOS scopes are
very rarely used, only set this parameter if you are the system administrator in charge of all the
NetBIOS systems you communicate with.

-W|--workgroup=WORKGROUP
Set the SMB domain of the username. This overrides the default domain which is the domain defined in
smb.conf. If the domain specified is the same as the servers NetBIOS name, it causes the client to
log on using the servers local SAM (as opposed to the Domain SAM).

Note that specifying this parameter here will override the workgroup parameter in the
/etc/samba/smb.conf file.

-r|--realm=REALM
Set the realm for the domain.

Note that specifying this parameter here will override the realm parameter in the /etc/samba/smb.conf
file.

-U|--user=[DOMAIN\]USERNAME[%PASSWORD]
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 (which is also permitted to also contain the password separated by a %), then
the LOGNAME variable (which is not permitted to contain a password) and if either exists, the value
is used. If these environmental variables are not found, the username found in a Kerberos Credentials
cache may be used.

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 or passing user-supplied values onto the command
line. For security it is better to let the Samba client tool ask for the password if needed, or
obtain the password once with kinit.

While Samba will attempt to scrub the password from the process title (as seen in ps), this is after
startup and so is subject to a race.

-N|--no-pass
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.

--password
Specify the password on the commandline.

If --password is not specified, the tool will check the PASSWD environment variable, followed by
PASSWD_FD which is expected to contain an open file descriptor (FD) number.

Finally it will check PASSWD_FILE (containing a file path to be opened). The file should only contain
the password. Make certain that the permissions on the file restrict access from unwanted users!

While Samba will attempt to scrub the password from the process title (as seen in ps), this is after
startup and so is subject to a race.

--pw-nt-hash
The supplied password is the NT hash.

-A|--authentication-file=filename
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!

-P|--machine-pass
Use stored machine account password.

--simple-bind-dn=DN
DN to use for a simple bind.

--use-kerberos=desired|required|off
This parameter determines whether Samba client tools will try to authenticate using Kerberos. For
Kerberos authentication you need to use dns names instead of IP addresses when connecting to a
service.

Note that specifying this parameter here will override the client use kerberos parameter in the
/etc/samba/smb.conf file.

--use-krb5-ccache=CCACHE
Specifies the credential cache location for Kerberos authentication.

This will set --use-kerberos=required too.

--use-winbind-ccache
Try to use the credential cache by winbind.

--client-protection=sign|encrypt|off
Sets the connection protection the client tool should use.

Note that specifying this parameter here will override the client protection parameter in the
/etc/samba/smb.conf file.

In case you need more fine grained control you can use: --option=clientsmbencrypt=OPTION,
--option=clientipcsigning=OPTION, --option=clientsigning=OPTION.

SMB URLS

       SMB URL's should be specified in the following format:

           smb://[[[domain;]user[:password@]]server[/share[/path[/file]]]]

           smb:// means all the workgroups

           smb://name/ means, if name is a workgroup, all the servers in this workgroup, or if name is a server, all the shares on this server.

EXAMPLES

           # Recursively download 'src' directory
           smbget --recursive smb://rhonwyn/jelmer/src
           # Download FreeBSD ISO and enable resuming
           smbget --resume smb://rhonwyn/isos/FreeBSD5.1.iso
           # Recursively download all ISOs
           smbget --recursive --resume smb://rhonwyn/isos
           # Backup my data on rhonwyn
           smbget --recursive -resume smb://rhonwyn/

BUGS

       Permission denied is returned in some cases where the cause of the error is unknown (such as an illegally
       formatted smb:// url or trying to get a directory without --resursive turned on).
