Quick Links. Search Forums. Show Threads. Show Posts. It offers an interface similar to that of the ftp program see ftp 1. Oper- ations include things like getting files from the server to the local machine, putting files from the local machine to the server, retriev- ing directory information from the server and so on. The server name is looked up according to either the -R parameter to smbclient or using the name resolve order parameter in the smb.

If this parameter is supplied, the -N option sup- press 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.

Lowercase or mixed case passwords may be rejected by these servers. Be cautious about including passwords in scripts. See the socket options parameter in the smb.

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 : o 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. Note that this method is only used if the NetBIOS name type being queried is the 0x20 server name type, otherwise it is ignored.

If no WINS server has been specified this method will be ignored. 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 smb.

Linux smbclient command

The default order is lmhosts, host, wins, bcast and without this parameter or any entry in the name resolve order parameter of the smb. If the receiving computer is running WinPopup the user will receive the message and probably a beep.

If they are not running Win- Popup the message will be lost, and no error message will occur. The message is also automatically truncated if the message is over bytes, as this is the limit of the protocol. One useful trick is to cat the message through smbclient.

For example: cat mymessage. See the message command parameter in the smb. This is useful when accessing a ser- vice 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. The default value if this parameter is not specified is zero. The higher this value, the more detail will be logged to the log files about the activities of the client. 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. If debuglevel is set to the letter 'A', then all debug messages will be printed. This setting is for developers only and people who really want to know how the code works internally.Exit Print View.

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 bytes, as this is the limit of the protocol. One useful trick is to pipe the message through smbclient. See the message command parameter in the smb. Note that to connect to a Windows server with encrypted transport selecting a max-protocol of SMB3 is required.

It should be specified in standard "a.Mounting an SMB Share. However, to mount and work with SMB shares, you must also install the cifs-utils package:. The cifs. Depending on the protocol version, not all SMB features are implemented.

These extensions are also supported by the cifs. This is the default on Samba servers. For example:. By default, the kernel module uses SMB 2 or the highest later protocol version supported by the server. To verify if UNIX extensions are enabled, display the options of the mounted share:. If the unix entry is displayed in the list of mount options, UNIX extensions are enabled. To manually mount an SMB share, use the mount utility with the -t cifs parameter:. In the -o options parameter, you can specify options that will be used to mount the share.

To enable the system to mount a share automatically, you must store the user name, password, and domain name in a credentials file. In certain situations, administrators want to mount a share without entering the user name and password. To implement this, create a credentials file.

The credentials you provide to mount a share determine the access permissions on the mount point by default. However, in certain situations, the administrator wants to mount a share automatically when the system boots, but users should perform actions on the share's content using their own credentials. The multiuser mount options lets you configure this scenario. The root user mounts the share using the multiuser option and an account that has minimal access to the contents of the share.

Regular users can then provide their user name and password to the current session's kernel keyring using the cifscreds utility. If the user accesses the content of the mounted share, the kernel uses the credentials from the kernel keyring instead of the one initially used to mount the share.

Mounting a Share with the multiuser Option. To mount a share automatically with the multiuser option when the system boots:. To verify if a share is mounted with the multiuser option:.

smbclient man

Accessing a Share as a User. If an SMB share is mounted with the multiuser option, users can provide their credentials for the server to the kernel's keyring:. Now, when the user performs operations in the directory that contains the mounted SMB share, the server applies the file system permissions for this user, instead of the one initially used when the share was mounted. Multiple users can perform operations using their own credentials on the mounted share at the same time.

Frequently Used Mount Options. How the connection will be established with the server. For example, which SMB protocol version is used when connecting to the server.

How the share will be mounted into the local file system. For example, if the system overrides the remote file and directory permissions to enable multiple local users to access the content on the server. Alternatively, specify a credentials file using the credentials option. Therefore, use seal together with the vers mount option set to 3.

For a list of supported values, see the option's description in the mount. For security reasons, do not use the insecure ntlm security mode. Providing SMB Shares Here are the common uses of Markdown.This tool is part of the samba 7 suite.

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. The server name is looked up according to either the -R parameter to smbclient or using the name resolve order parameter in the smb.

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.

Lowercase or mixed case passwords may be rejected by these servers. 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:. 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.

If this parameter is not set then the name resolve order defined in the smb. The default order is lmhosts, host, wins, bcast and without this parameter or any entry in the name resolve order parameter of the smb.

This options allows you to send messages, using the "WinPopup" protocol, to another computer. 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 bytes, as this is the limit of the protocol.

One useful trick is to pipe the message through smbclient. See the message command parameter in the smb. This number is the TCP port number that will be used when making connections to the server.

This parameter provides combined with -L easy parseable output that allows processing with utilities such as grep and cut. This allows the user to select the highest SMB protocol level that smbclient will use to connect to the server. Note that to connect to a Windows server with encrypted transport selecting a max-protocol of SMB3 is required.

IP address is the address of the server to connect to. It should be specified in standard "a.This tool is part of the samba 7 suite.

It permits much more than just browsing, files can be opened and read or written, permissions changed, file times modified, attributes and ACL's can be manipulated, and so on. Of course, its functionality includes all the capabilities commonly called browsing. This man page describes the configuration options for this tool so that the user may obtain greatest utility of use. Shows all workgroups or domains that are visible in the network.

The behavior matches that of the Microsoft Windows Explorer. It is the responsibility of the application that calls this library to set this to a sensible value. This is a compile-time option. This value determines the maximum number of local master browsers to query for the list of workgroups. In order to ensure that the list is complete for those present on the network, all master browsers must be queried.

If there are a large number of workgroups on the network, the time spent querying will be significant. For small networks just a few workgroupsit is suggested to set this value to 0, instructing libsmbclient to query all local master browsers. In an environment that has many workgroups a more reasonable setting may be around 3. This command causes libsmbclient to perform a name look-up. When libsmbclient is invoked by an application it searches for a directory called.

It then searches for a file called smb.

The 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. Name libsmbclient — An extension library for browsers and that can be used as a generic browsing API.

It only takes a minute to sign up. I have been given an account on a Windows file server. The to me very strange situation is that. I have neither "display content" nor "change into" permission for the lower level subdirectories.

That should not be a problem and it is not for smbclient. The Windows admin has given my user additional permissions so that I can now see contents of the moint point. And now I can reach the deeper level subdirectories via the mount, too.

We have not determined yet what the minimal set of Windows permissions is which we need for this to work in the current configuration. However, the problem must be on the Linux side anyway. I had the Windows admin reset the permissions of the share so that I could test the suggestions in the answers.

Unfortunately the problem disappeared. As before I cannot see the contents of the share but now the mount can access the deep subdirectories.

Very strange. A remark intika: I was going to make an additional bounty for your answer but while I was doing so you for some reason deleted your answer I just realize that windowsdomain in the smbclient command was incomplete. Probably not relevant as this works. It was just name instead of name. However, that is a difference in the configuration between the commands.

Unfortunately I cannot check whether mount would work if I use the wrong domain with it as I cannot change the permissions on the Windows server back to their original settings. I have to wait for the Windows admins to do that on Monday. The path length within the share is 85 characters for the directory I want to work in. I should be able to access its parent, too, i. You maybe hitting the infamous Maximum Path Length Limitation. There is an Unicode way to access the API, which has a 32, limitation.

Now question is, how long is your path which you want to list. The second question is which smbclient is using vs. Quoting from the smbclient man pages:. Whereas I could not find anything mentioning mount. I presume you are not using smb1 as it is considered unsafe.

There maybe NTLM security implications if you are using smb3 protocol, which could prevent you listing the directory. Note: you should check the log event viewer on the server not on the client, to see what is going on. I think you may suffer from the dot smbv2 bug when using mount.

Which in short is:. When mounting a Windows share that is the root of a drive eg.It communicates with a LAN Manager serveroffering an interface similar to that of the ftp program. 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.

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.

smbclient man

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 eg. If not given, the command will use suitable defaults. Parameters shown in angle brackets eg. 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.

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.

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. Lists available shares on host. Using this command would display information similar to the below output:. Connects to the ch share on the networked computer hope using the login password " password ". Home Help Linux. Description Syntax Examples Related commands Linux commands help.
