NAMEsmbclient - ftp-like client to access SMB/CIFS resources on serversSYNOPSISsmbclient [-b <buffer size>] [-d debuglevel] [-e] [-L <netbios name>] [-U username] [-I destinationIP] [-M <netbios name>] [-m maxprotocol] [-A authfile] [-N] [-C] [-g] [-i scope] [-O <socket options>] [-p port] [-R <name resolve order>] [-s <smb config file>] [-t <per-operation timeout in seconds>] [-k] [-P] [-c <command>] smbclient {servicename} [password] [-b <buffer size>] [-d debuglevel] [-e] [-D Directory] [-U username] [-W workgroup] [-M <netbios name>] [-m maxprotocol] [-A authfile] [-N] [-C] [-g] [-l log-basename] [-I destinationIP] [-E] [-c <command string>] [-i scope] [-O <socket options>] [-p port] [-R <name resolve order>] [-s <smb config file>] [-t <per-operation timeout in seconds>] [-T<c|x>IXFvgbNan] [-k] DESCRIPTIONThis tool is part of the samba(7) suite.smbclient is a client that can 'talk' to an SMB/CIFS server. It offers an interface similar to that of the ftp program (see ftp(1)). Operations include things like getting files from the server to the local machine, putting files from the local machine to the server, retrieving directory information from the server and so on. OPTIONSservicenameservicename is the name of the service you want to use on
the server. A service name takes the form //server/service where server
is the NetBIOS name of the SMB/CIFS server offering the desired service
and service is the name of the service offered. Thus to connect to the
service "printer" on the SMB/CIFS server "smbserver", you
would use the servicename //smbserver/printer
Note that the server name required is NOT necessarily the IP (DNS) host name of the server ! The name required is a NetBIOS server name, which may or may not be the same as the IP hostname of the machine running the server. The server name is looked up according to either the -R parameter to smbclient or using the name resolve order parameter in the smb.conf(5) file, allowing an administrator to change the order and methods by which server names are looked up. 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> This option is used by the programs in the Samba suite 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 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.
The default order is lmhosts, host, wins, bcast and without this parameter or any entry in the name resolve order parameter of the smb.conf(5) file the name resolution methods will be attempted in this order. -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 highest available SMB3 protocol version. To connect using SMB2 or SMB1
protocol, use the strings SMB2 or NT1 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 ignored 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.
•n - In combination with the c flag,
do not actually create the archive, instead perform a dry run that attempts
everything that involved in creation other than writing the file.
•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.
•v - Verbose. Makes tar print out the files
being processed. By default tar is not verbose. This is the same as tarmode
verbose.
•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.
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 -'. OPERATIONSOnce 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.
deltree <mask> The client will request that the server attempt to delete
all files and directories matching mask from the current working
directory on the server. Note this will recursively delete files and
directories within the directories selected even without the recurse command
being set. If any of the delete requests fail the command will stop processing
at that point, leaving files and directories not yet processed untouched. This
is by design.
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> [-f] Rename files in the current working directory on the
server from old filename to new filename. The optional -f switch
allows for superseding the destination file, if it exists. This is supported
by NT1 protocol dialect and SMB2 protocol family.
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|verbose|noverbose> 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.
utimes <filename> <create time> <access time> <write time> < change time> Changes the timestamps on a file by name. Times should be
specified in the format [YY]YY:MM:DD-HH:MM:SS or -1 for no change.
NOTESSome 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. ENVIRONMENT VARIABLESThe 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. INSTALLATIONThe 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. DIAGNOSTICSMost diagnostics issued by the client are logged in a specified log file. The log file name is specified at compile time, but may be overridden on the command line.The number and nature of diagnostics available depends on the debug level used by the client. If you have problems, set the debug level to 3 and peruse the log files. VERSIONThis man page is part of version 4.13.17 of the Samba suite.AUTHORThe 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.
