命令简述（DESCRIPTION）

该命令是samba(7)套件的一部分。

smbclient用于与SMB/CIFS Server进行“交流”。它提供了类似于终端下的ftp(1)程序的界面。支持的操作包括从服务器获取文件到本地机器，将文件从本地机器上传到服务器，从服务器检索目录信息等等。

命令支持的选项及含义（OPTIONS）

servicename
servicename是要在server上使用的service的描述。servicename采用//server/service的形式：其中server是提供所需服务的SMB/CIFS Server的NetBIOS Name；service是所提供服务的名称；
因此，要连接到名为“smbserver”的SMB/CIFS Server上的“printer”服务，servicename的格式为：//smbserver/printer

注意，所需的server不一定是服务器的IP（DNS）主机名！所需的名称是Server的NetBIOS Name，NetBIOS Name可能与计算机的IP主机名相同，也可能不相同。

根据「smbclient的-R指定的参数」或「smb.conf(5)文件中的name resolve order指定的参数」来进行查找server名称，允许管理员更改查找server名称的顺序和方法。

password
The password required to access the specified service on the specified server. If this parameter is
supplied, the -N option (suppress password prompt) is assumed.

There is no default password. If no password is supplied on the command line (either by using this
parameter or adding a password to the -U option (see below)) and the -N option is not specified, the
client will prompt for a password, even if the desired service does not require one. (If no password is
required, simply press ENTER to provide a null password.)

Note: Some servers (including OS/2 and Windows for Workgroups) insist on an uppercase password. Lowercase
or mixed case passwords may be rejected by these servers.

Be cautious about including passwords in scripts.

-R|–name-resolve <name resolve order>
在Samba套件中的程序，使用此选项来确定「哪些命名服务」以及「以什么顺序」将NetBIOS Name解析为IP地址。该选项采用不同名称解析选项的空格分隔的字符串。
<name resolve order>的格式为空格分隔的多个选项。

支持的选项：”lmhosts”, “host”, “wins”, “bcast”。这些选项使NetBIOS Name按如下进行所述进行解析：

  • lmhosts: 在Samba的lmhosts文件中查找IP地址。如果lmhosts中的行没有绑定到NetBIOS Name的名称类型（参阅lmhosts(5)），然后查找任何名称类型。
  • host: 使用系统/etc/hosts、NIS、DNS查找来执行主机名到IP地址解析。这种名称解析方法是依赖于操作系统的，例如在IRIX或Solaris上，这可以由/etc/nsswitch.conf文件控制）。注意，仅当正在查询的NetBIOS Name类型为0x20（server）的名字类型时，才使用此方法，否则将被忽略。
  • wins: 使用wins server参数中列出的IP地址来查询名称。如果没有指定WINS服务器，则此方法将被忽略。
  • bcast：在interfaces参数中列出的每个已知的本地接口上进行广播。这是名称解析方法中最不可靠的，因为它取决于目标主机在本地连接的子网上。

如果未设置此参数，则将使用smb.conf(5)文件中参数（name resolve order）中定义的名称解析顺序。

默认的顺序是lmhosts，host，wins，bcast。如果没有使用-R并且没有在smb.conf(5)文件的的name resolve order参数指定任何条目，将按此顺序尝试名称解析方法。

-M|–message NetBIOS name
This options allows you to send messages, using the “WinPopup” protocol, to another computer. Once a
connection is established you then type your message, pressing ^D (control-D) to end.

If the receiving computer is running WinPopup the user will receive the message and probably a beep. If
they are not running WinPopup the message will be lost, and no error message will occur.

The message is also automatically truncated if the message is over 1600 bytes, as this is the limit of
the protocol.

One useful trick is to pipe the message through smbclient. For example: smbclient -M FRED < mymessage.txt
will send the message in the file mymessage.txt to the machine FRED.

You may also find the -U and -I options useful, as they allow you to control the FROM and TO parts of the
message.

See the message command parameter in the smb.conf(5) for a description of how to handle incoming WinPopup
messages in Samba.

Note: Copy WinPopup into the startup group on your WfWg PCs if you want them to always be able to receive
messages.

-p|–port port
This number is the TCP port number that will be used when making connections to the server. The standard
(well-known) TCP port number for an SMB/CIFS server is 139, which is the default.

-g|–grepable
This parameter provides combined with -L easy parseable output that allows processing with utilities such
as grep and cut.

-m|–max-protocol protocol
This allows the user to select the highest SMB protocol level that smbclient 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 respectively. Note that to connect to a Windows 2012
server with encrypted transport selecting a max-protocol of SMB3 is required.

-P|–machine-pass
Make queries to the external server using the machine account of the local server.

-I|–ip-address IP-address
IP address is the address of the server to connect to. It should be specified in standard “a.b.c.d”
notation.

Normally the client would attempt to locate a named SMB/CIFS server by looking it up via the NetBIOS name
resolution mechanism described above in the name resolve order parameter above. Using this parameter will
force the client to assume that the server is on the machine with the specified IP address and the
NetBIOS name component of the resource being connected to will be ignored.

There is no default for this parameter. If not supplied, it will be determined automatically by the
client as described above.

-E|–stderr
This parameter causes the client to write messages to the standard error stream (stderr) rather than to
the standard output stream.

By default, the client writes messages to standard output – typically the user’s tty.

-L|–list
This option allows you to look at what services are available on a server. You use it as smbclient -L
host and a list should appear. The -I option may be useful if your NetBIOS names don’t match your TCP/IP
DNS host names or if you are trying to reach a host on another network.

-b|–send-buffer buffersize
When sending or receiving files, smbclient uses an internal buffer sized by the maximum number of allowed
requests to the connected server. This command allows this size to be set to any range between 0 (which
means use the default server controlled size) bytes and 16776960 (0xFFFF00) bytes. Using the server
controlled size is the most efficient as smbclient will pipeline as many simultaneous reads or writes
needed to keep the server as busy as possible. Setting this to any other size will slow down the
transfer. This can also be set using the iosize command inside smbclient.

-B|–browse
Browse SMB servers using DNS.

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

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.

-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 ingnored and no password will be used.

-k|–kerberos
Try to authenticate with kerberos. Only useful in an Active Directory environment.

-C|–use-ccache
Try to use the credentials cached by winbind.

-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.

-U|–user=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, then the LOGNAME variable and if either exists, the string is uppercased. If these
environmental variables are not found, the username GUEST is 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. 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.

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

-e|–encrypt
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.

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

-n|–netbiosname <primary NetBIOS name>
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 smb.conf file. However, a command line setting will take
precedence over settings in smb.conf.

-i|–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=domain
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).

-O|–socket-options socket options
TCP socket options to set on the client socket. See the socket options parameter in the smb.conf manual
page for the list of valid options.

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

–usage
Display brief usage message.

-t|–timeout <timeout-seconds>
This allows the user to tune the default timeout used for each SMB request. The default setting is 20
seconds. Increase it if requests to the server sometimes time out. This can happen when SMB3 encryption
is selected and smbclient is overwhelming the server with requests. This can also be set using the
timeout command inside smbclient.

-T|–tar tar options
smbclient may be used to create tar(1) compatible backups of all the files on an SMB/CIFS share. The
secondary tar flags that can be given to this option are:

· c – Create a tar backup archive on the local system. Must be followed by the name of a tar file, tape

device or “-” for standard output. If using standard output you must turn the log level to its lowest

value -d0 to avoid corrupting your tar file. This flag is mutually exclusive with the x flag.

· x – Extract (restore) a local tar file back to a share. Unless the -D option is given, the tar files

will be restored from the top level of the share. Must be followed by the name of the tar file,

device or “-” for standard input. Mutually exclusive with the c flag. Restored files have their

creation times (mtime) set to the date saved in the tar file. Directories currently do not get their

creation dates restored properly.

· I – Include files and directories. Is the default behavior when filenames are specified above. Causes

files to be included in an extract or create (and therefore everything else to be excluded). See

example below. Filename globbing works in one of two ways. See r below.

· X – Exclude files and directories. Causes files to be excluded from an extract or create. See example

below. Filename globbing works in one of two ways. See r below.

· F – File containing a list of files and directories. The F causes the name following the tarfile to

create to be read as a filename that contains a list of files and directories to be included in an

extract or create (and therefore everything else to be excluded). See example below. Filename

globbing works in one of two ways. See r below.

· b – Blocksize. Must be followed by a valid (greater than zero) blocksize. Causes tar file to be

written out in blocksize*TBLOCK (512 byte) blocks.

· g – Incremental. Only back up files that have the archive bit set. Useful only with the c flag.

· q – Quiet. Keeps tar from printing diagnostics as it works. This is the same as tarmode quiet.

· r – Use wildcard matching to include or exclude. Deprecated.

· N – Newer than. Must be followed by the name of a file whose date is compared against files found on

the share during a create. Only files newer than the file specified are backed up to the tar file.

Useful only with the c flag.

· a – Set archive bit. Causes the archive bit to be reset when a file is backed up. Useful with the g

and c flags.

Tar Long File Names

smbclient’s tar option now supports long file names both on backup and restore. However, the full path name

of the file must be less than 1024 bytes. Also, when a tar archive is created, smbclient’s tar option places

all files in the archive with relative names, not absolute names.

Tar Filenames

All file names can be given as DOS path names (with ‘\\’ as the component separator) or as UNIX path names

(with ‘/’ as the component separator).

Examples

Restore from tar file backup.tar into myshare on mypc (no password on share).

smbclient //mypc/myshare “” -N -Tx backup.tar

Restore everything except users/docs

smbclient //mypc/myshare “” -N -TXx backup.tar users/docs

Create a tar file of the files beneath users/docs.

smbclient //mypc/myshare “” -N -Tc backup.tar users/docs

Create the same tar file as above, but now use a DOS path name.

smbclient //mypc/myshare “” -N -Tc backup.tar users\edocs

Create a tar file of the files listed in the file tarlist.

smbclient //mypc/myshare “” -N -TcF backup.tar tarlist

Create a tar file of all the files and directories in the share.

smbclient //mypc/myshare “” -N -Tc backup.tar *

-D|–directory initial directory
Change to initial directory before starting. Probably only of any use with the tar -T option.

-c|–command command string
command string is a semicolon-separated list of commands to be executed instead of prompting from stdin.
-N is implied by -c.

This is particularly useful in scripts and for printing stdin to the server, e.g. -c ‘print -‘.

连接共享后，在「smb: \>」中可执行的命令及含义（OPERATIONS）

Once the client is running, the user is presented with a prompt :

smb:\>

The backslash (“\\”) indicates the current working directory on the server, and will change if the current

working directory is changed.

The prompt indicates that the client is ready and waiting to carry out a user command. Each command is a

single word, optionally followed by parameters specific to that command. Command and parameters are

space-delimited unless these notes specifically state otherwise. All commands are case-insensitive.

Parameters to commands may or may not be case sensitive, depending on the command.

You can specify file names which have spaces in them by quoting the name with double quotes, for example “a

long file name”.

Parameters shown in square brackets (e.g., “[parameter]”) are optional. If not given, the command will use

suitable defaults. Parameters shown in angle brackets (e.g., “<parameter>”) are required.

Note that all commands operating on the server are actually performed by issuing a request to the server.

Thus the behavior may vary from server to server, depending on how the server was implemented.

The commands available are given here in alphabetical order.

? [command]
If command is specified, the ? command will display a brief informative message about the specified

command. If no command is specified, a list of available commands will be displayed.

! [shell command]
If shell command is specified, the ! command will execute a shell locally and run the specified shell

command. If no command is specified, a local shell will be run.

allinfo file
The client will request that the server return all known information about a file or directory (including

streams).

altname file
The client will request that the server return the “alternate” name (the 8.3 name) for a file or

directory.

archive <number>
Sets the archive level when operating on files. 0 means ignore the archive bit, 1 means only operate on

files with this bit set, 2 means only operate on files with this bit set and reset it after operation, 3

means operate on all files and reset it after operation. The default is 0.

backup
Toggle the state of the “backup intent” flag sent to the server on directory listings and file opens. If

the “backup intent” flag is true, the server will try and bypass some file system checks if the user has

been granted SE_BACKUP or SE_RESTORE privileges. This state is useful when performing a backup or restore

operation.

blocksize <number>
Sets the blocksize parameter for a tar operation. The default is 20. Causes tar file to be written out in

blocksize*TBLOCK (normally 512 byte) units.

cancel jobid0 [jobid1] … [jobidN]
The client will request that the server cancel the printjobs identified by the given numeric print job

ids.

case_sensitive
Toggles the setting of the flag in SMB packets that tells the server to treat filenames as case

sensitive. Set to OFF by default (tells file server to treat filenames as case insensitive). Only

currently affects Samba 3.0.5 and above file servers with the case sensitive parameter set to auto in the

smb.conf.

cd <directory name>
If “directory name” is specified, the current working directory on the server will be changed to the

directory specified. This operation will fail if for any reason the specified directory is inaccessible.

If no directory name is specified, the current working directory on the server will be reported.

chmod file mode in octal
This command depends on the server supporting the CIFS UNIX extensions and will fail if the server does

not. The client requests that the server change the UNIX permissions to the given octal mode, in standard

UNIX format.

chown file uid gid
This command depends on the server supporting the CIFS UNIX extensions and will fail if the server does

not. The client requests that the server change the UNIX user and group ownership to the given decimal

values. Note there is currently no way to remotely look up the UNIX uid and gid values for a given name.

This may be addressed in future versions of the CIFS UNIX extensions.

close <fileid>
Closes a file explicitly opened by the open command. Used for internal Samba testing purposes.

del <mask>
The client will request that the server attempt to delete all files matching mask from the current

working directory on the server.

dir <mask>
A list of the files matching mask in the current working directory on the server will be retrieved from

the server and displayed.

du <filename>
Does a directory listing and then prints out the current disk usage and free space on a share.

echo <number> <data>
Does an SMBecho request to ping the server. Used for internal Samba testing purposes.

exit
Terminate the connection with the server and exit from the program.

get <remote file name> [local file name]
Copy the file called remote file name from the server to the machine running the client. If specified,

name the local copy local file name. Note that all transfers in smbclient are binary. See also the

lowercase command.

getfacl <filename>
Requires the server support the UNIX extensions. Requests and prints the POSIX ACL on a file.

hardlink <src> <dest>
Creates a hardlink on the server using Windows CIFS semantics.

help [command]
See the ? command above.

history
Displays the command history.

iosize <bytes>
When sending or receiving files, smbclient uses an internal buffer sized by the maximum number of allowed

requests to the connected server. This command allows this size to be set to any range between 0 (which

means use the default server controlled size) bytes and 16776960 (0xFFFF00) bytes. Using the server

controlled size is the most efficient as smbclient will pipeline as many simultaneous reads or writes

needed to keep the server as busy as possible. Setting this to any other size will slow down the

transfer.

lcd [directory name]
If directory name is specified, the current working directory on the local machine will be changed to the

directory specified. This operation will fail if for any reason the specified directory is inaccessible.

If no directory name is specified, the name of the current working directory on the local machine will be

reported.

link target linkname
This command depends on the server supporting the CIFS UNIX extensions and will fail if the server does

not. The client requests that the server create a hard link between the linkname and target files. The

linkname file must not exist.

listconnect
Show the current connections held for DFS purposes.

lock <filenum> <r|w> <hex-start> <hex-len>
This command depends on the server supporting the CIFS UNIX extensions and will fail if the server does

not. Tries to set a POSIX fcntl lock of the given type on the given range. Used for internal Samba

testing purposes.

logon <username> <password>
Establishes a new vuid for this session by logging on again. Replaces the current vuid. Prints out the

new vuid. Used for internal Samba testing purposes.

logoff
Logs the user off the server, closing the session. Used for internal Samba testing purposes.

lowercase
Toggle lowercasing of filenames for the get and mget commands.

When lowercasing is toggled ON, local filenames are converted to lowercase when using the get and mget

commands. This is often useful when copying (say) MSDOS files from a server, because lowercase filenames

are the norm on UNIX systems.

ls <mask>
See the dir command above.

mask <mask>
This command allows the user to set up a mask which will be used during recursive operation of the mget

and mput commands.

The masks specified to the mget and mput commands act as filters for directories rather than files when

recursion is toggled ON.

The mask specified with the mask command is necessary to filter files within those directories. For

example, if the mask specified in an mget command is “source*” and the mask specified with the mask

command is “*.c” and recursion is toggled ON, the mget command will retrieve all files matching “*.c” in

all directories below and including all directories matching “source*” in the current working directory.

Note that the value for mask defaults to blank (equivalent to “*”) and remains so until the mask command

is used to change it. It retains the most recently specified value indefinitely. To avoid unexpected

results it would be wise to change the value of mask back to “*” after using the mget or mput commands.

md <directory name>
See the mkdir command.

mget <mask>
Copy all files matching mask from the server to the machine running the client.

Note that mask is interpreted differently during recursive operation and non-recursive operation – refer

to the recurse and mask commands for more information. Note that all transfers in smbclient are binary.

See also the lowercase command.

mkdir <directory name>
Create a new directory on the server (user access privileges permitting) with the specified name.

more <file name>
Fetch a remote file and view it with the contents of your PAGER environment variable.

mput <mask>
Copy all files matching mask in the current working directory on the local machine to the current working

directory on the server.

Note that mask is interpreted differently during recursive operation and non-recursive operation – refer

to the recurse and mask commands for more information. Note that all transfers in smbclient are binary.

notify <dir name>
Query a directory for change notifications. This command issues a recursive filechangenotify call for all

possible changes. As changes come in will print one line per change. See

https://msdn.microsoft.com/en-us/library/dn392331.aspx for a description of the action numbers that this

command prints.

This command never ends, it waits for event indefinitely.

posix
Query the remote server to see if it supports the CIFS UNIX extensions and prints out the list of

capabilities supported. If so, turn on POSIX pathname processing and large file read/writes (if

available),.

posix_encrypt <domain> <username> <password>
This command depends on the server supporting the CIFS UNIX extensions and will fail if the server does

not. Attempt to negotiate SMB encryption on this connection. If smbclient connected with kerberos

credentials (-k) the arguments to this command are ignored and the kerberos credentials are used to

negotiate GSSAPI signing and sealing instead. See also the -e option to smbclient to force encryption on

initial connection. This command is new with Samba 3.2.

posix_open <filename> <octal mode>
This command depends on the server supporting the CIFS UNIX extensions and will fail if the server does

not. Opens a remote file using the CIFS UNIX extensions and prints a fileid. Used for internal Samba

testing purposes.

posix_mkdir <directoryname> <octal mode>
This command depends on the server supporting the CIFS UNIX extensions and will fail if the server does

not. Creates a remote directory using the CIFS UNIX extensions with the given mode.

posix_rmdir <directoryname>
This command depends on the server supporting the CIFS UNIX extensions and will fail if the server does

not. Deletes a remote directory using the CIFS UNIX extensions.

posix_unlink <filename>
This command depends on the server supporting the CIFS UNIX extensions and will fail if the server does

not. Deletes a remote file using the CIFS UNIX extensions.

posix_whoami
Query the remote server for the user token using the CIFS UNIX extensions WHOAMI call. Prints out the

guest status, user, group, group list and sid list that the remote server is using on behalf of the

logged on user.

print <file name>
Print the specified file from the local machine through a printable service on the server.

prompt
Toggle prompting for filenames during operation of the mget and mput commands.

When toggled ON, the user will be prompted to confirm the transfer of each file during these commands.

When toggled OFF, all specified files will be transferred without prompting.

put <local file name> [remote file name]
Copy the file called local file name from the machine running the client to the server. If specified,

name the remote copy remote file name. Note that all transfers in smbclient are binary. See also the

lowercase command.

queue
Displays the print queue, showing the job id, name, size and current status.

quit
See the exit command.

readlink symlinkname
This command depends on the server supporting the CIFS UNIX extensions and will fail if the server does

not. Print the value of the symlink “symlinkname”.

rd <directory name>
See the rmdir command.

recurse
Toggle directory recursion for the commands mget and mput.

When toggled ON, these commands will process all directories in the source directory (i.e., the directory

they are copying from ) and will recurse into any that match the mask specified to the command. Only

files that match the mask specified using the mask command will be retrieved. See also the mask command.

When recursion is toggled OFF, only files from the current working directory on the source machine that

match the mask specified to the mget or mput commands will be copied, and any mask specified using the

mask command will be ignored.

rename <old filename> <new filename>
Rename files in the current working directory on the server from old filename to new filename.

rm <mask>
Remove all files matching mask from the current working directory on the server.

rmdir <directory name>
Remove the specified directory (user access privileges permitting) from the server.

scopy <source filename> <destination filename>
Attempt to copy a file on the server using the most efficient server-side copy calls. Falls back to using

read then write if server doesn’t support server-side copy.

setmode <filename> <perm=[+|\-]rsha>
A version of the DOS attrib command to set file permissions. For example:

setmode myfile +r

would make myfile read only.

showconnect
Show the currently active connection held for DFS purposes.

stat file
This command depends on the server supporting the CIFS UNIX extensions and will fail if the server does

not. The client requests the UNIX basic info level and prints out the same info that the Linux stat

command would about the file. This includes the size, blocks used on disk, file type, permissions, inode

number, number of links and finally the three timestamps (access, modify and change). If the file is a

special file (symlink, character or block device, fifo or socket) then extra information may also be

printed.

symlink target linkname
This command depends on the server supporting the CIFS UNIX extensions and will fail if the server does

not. The client requests that the server create a symbolic hard link between the target and linkname

files. The linkname file must not exist. Note that the server will not create a link to any path that

lies outside the currently connected share. This is enforced by the Samba server.

tar <c|x>[IXbgNa]
Performs a tar operation – see the -T command line option above. Behavior may be affected by the tarmode

command (see below). Using g (incremental) and N (newer) will affect tarmode settings. Note that using

the “-” option with tar x may not work – use the command line option instead.

blocksize <blocksize>
Blocksize. Must be followed by a valid (greater than zero) blocksize. Causes tar file to be written out

in blocksize*TBLOCK (512 byte) blocks.

tarmode <full|inc|reset|noreset|system|nosystem|hidden|nohidden>
Changes tar’s behavior with regard to DOS attributes. There are 4 modes which can be turned on or off.

Incremental mode (default off). When off (using full) tar will back up everything regardless of the

archive bit setting. When on (using inc), tar will only back up files with the archive bit set.

Reset mode (default off). When on (using reset), tar will remove the archive bit on all files it backs up

(implies read/write share). Use noreset to turn off.

System mode (default on). When off, tar will not backup system files. Use nosystem to turn off.

Hidden mode (default on). When off, tar will not backup hidden files. Use nohidden to turn off.

timeout <per-operation timeout in seconds>
This allows the user to tune the default timeout used for each SMB request. The default setting is 20

seconds. Increase it if requests to the server sometimes time out. This can happen when SMB3 encryption

is selected and smbclient is overwhelming the server with requests.

unlock <filenum> <hex-start> <hex-len>
This command depends on the server supporting the CIFS UNIX extensions and will fail if the server does

not. Tries to unlock a POSIX fcntl lock on the given range. Used for internal Samba testing purposes.

volume
Prints the current volume name of the share.

vuid <number>
Changes the currently used vuid in the protocol to the given arbitrary number. Without an argument prints

out the current vuid being used. Used for internal Samba testing purposes.

tcon <sharename>
Establishes a new tree connect (connection to a share). Replaces the current tree connect. Prints the new

tid (tree id). Used for internal Samba testing purposes.

tdis
Close the current share connection (tree disconnect). Used for internal Samba testing purposes.

tid <number>
Changes the current tree id (tid) in the protocol to a new arbitrary number. Without an argument, it

prints out the tid currently used. Used for internal Samba testing purposes.

注意事项（NOTES）

Some servers are fussy about the case of supplied usernames, passwords, share names (AKA service names) and

machine names. If you fail to connect try giving all parameters in uppercase.

It is often necessary to use the -n option when connecting to some types of servers. For example OS/2

LanManager insists on a valid NetBIOS name being used, so you need to supply a valid name that would be known

to the server.

smbclient supports long file names where the server supports the LANMAN2 protocol or above.

相关环境变量（ENVIRONMENT VARIABLES）

The variable USER may contain the username of the person using the client. This information is used only if

the protocol level is high enough to support session-level passwords.

The variable PASSWD may contain the password of the person using the client. This information is used only if

the protocol level is high enough to support session-level passwords.

The variable LIBSMB_PROG may contain the path, executed with system(), which the client should connect to

instead of connecting to a server. This functionality is primarily intended as a development aid, and works

best when using a LMHOSTS file

安装（INSTALLATION）

The location of the client program is a matter for individual system administrators. The following are thus

suggestions only.

It is recommended that the smbclient software be installed in the /usr/local/samba/bin/ or /usr/samba/bin/

directory, this directory readable by all, writeable only by root. The client program itself should be

executable by all. The client should NOT be setuid or setgid!

The client log files should be put in a directory readable and writeable only by the user.

To test the client, you will need to know the name of a running SMB/CIFS server. It is possible to run

smbd(8) as an ordinary user – running that server as a daemon on a user-accessible port (typically any port

number over 1024) would provide a suitable test server.

问题诊断（DIAGNOSTICS）

Client发出的大多数诊断都记录在指定的日志文件中。日志文件名是在编译时指定，但可能在命令行上进行覆盖。

诊断可用的数量和性质取决于Client使用的调试级别。如果有问题，请将调试级别设置为3，并仔细阅读日志文件。

文档版本（VERSION）

原文 “

This man page is correct for version 3.2 of the Samba suite.

”

该文档对于3.2版本的Samba套件是正确的。我使用的Samba的版本是4.6.5，从发行版的源中直接安装的，似乎发行版的文档并没有更新。

后来，我又去官网找了一通：
https://www.samba.org/samba/docs/man/manpages/smbclient.1.html
https://www.samba.org/samba/docs/man/manpages-3/smbclient.1.html
似乎也都是这个样子，所以可能smbclient没有什么更新吧。
