Smbclient linux to windows

Smbclient linux to windows

Машины с Linux (UNIX) могут также просматривать и монтировать SMB-ресурсы. Заметьте, что это может быть сделано когда сервером является либо машина с Windows, либо с сервером Samba!

Программа клиента SMB для UNIX-машин включена в дистрибутив Samba. Она обеспечивает ftp-подобный интерфейс командной строки. Вы можете использовать эту утилиту для переноса файлов между ‘сервером’ под управлением Windows и клиентом под Linux.

Большинство дистрибутивов Linux также включают полезный пакет smbfs, который позволяет монтировать и размонтировать SMB-ресурсы. Больше информации о smbfs можно получить дальше.

Для того, чтобы увидеть какие ресурсы доступны на данной машине, выполните команду:

где ‘host’ это имя машины, которую вы хотите видеть. Эта команда вернет список имен ‘сервисов’ — т.е. имен дисков или принтеров к которым может быть получен доступ. До тех пор, пока SMB сервер не будет настроен без управления доступом, он будет запрашивать у вас пароль. Введите в ответ на запрос пароль для пользователя ‘гость (guest)’ или ваш персональный пароль на этой машине.

Вывод этой команды должен выглядеть примерно так:

Browse list показывает другие SMB сервера в сети с доступными ресурсами.

Для использования клиента, выполните следующую команду:

где ‘service’ — имя машины и сервиса. Например, если вы пытаетесь обратиться к директории, которая доступна под именем ‘public’ на машине названной ‘zimmerman’, то имя сервиса должно звучать как \\zimmerman\public. Однако в следствии ограничений оболочки, вам необходимо спрятать обратный слэш, так что в итоге это командная строка выглядеть следующим образом:

где ‘mypasswd’ — символьная строка вашего пароля.

Вы получите приглашение smbclient:

Напечатайте ‘h’ чтобы получить помощь об использовании smbclient:

Если вы умеете использовать ftp, то вам не будут нужны справочные страницы о smbclient.

Хотя вы можете использовать smbclient для тестирования, вы скоро устанете использовать его в работе. Для работы вам скорее всего понадобится пакет smbfs. Smbfs поставляется с двумя простыми утилитами, smbmount и smbumount. Они работают подобно mount и umount для SMB-ресурсов.

Одно важное замечание: Чтобы использовать эти утилиты, у вас должна быть поддержка smbfs вкомпилированная в ядро!

Следующий пример показывает типичное использование smbmount для монтирования SMB-ресурса, названного «customers» с машины с именем «samba1»:

Запуск команды mount покажет вам, что ресурс смонтирован, точно также как и через экспорт NFS:

Пожалуйста прочитайте справочные страницы smbmount и smbumount для дополнительной информации о описанных выше операциях.

Smbclient linux to windows

Linux (UNIX) machines can also browse and mount SMB shares. Note that this can be done whether the server is a Windows machine or a Samba server!

An SMB client program for UNIX machines is included with the Samba distribution. It provides an ftp-like interface on the command line. You can use this utility to transfer files between a Windows ‘server’ and a Linux client.

Most Linux distributions also now include the useful smbfs package, which allows one to mount and umount SMB shares. More on smbfs below.

To see which shares are available on a given host, run:

where ‘host’ is the name of the machine that you wish to view. this will return a list of ‘service’ names — that is, names of drives or printers that it can share with you. Unless the SMB server has no security configured, it will ask you for a password. Get it the password for the ‘guest’ account or for your personal account on that machine.

The output of this command should look something like this:

The browse list shows other SMB servers with resources to share on the network.

To use the client, run:

where ‘service’ is a machine and share name. For example, if you are trying to reach a directory that has been shared as ‘public’ on a machine called zimmerman, the service would be called \\zimmerman\public. However, due to shell restrictions, you will need to escape the backslashes, so you end up with something like this:

where ‘mypasswd’ is the literal string of your password.

You will get the smbclient prompt:

Type ‘h’ to get help using smbclient:

If you can use ftp, you shouldn’t need the man pages for smbclient.

Although you can use smbclient for testing, you will soon tire of it for real work. For that you will probably want to use the smbfs package. Smbfs comes with two simple utilties, smbmount and smbumount. They work just like mount and umount for SMB shares.

One important thing to note: You must have smbfs support compiled into your kernel to use these utilities!

The following shows a typical use of smbmount to mount an SMB share called «customers» from a machine called «samba1»:

Issuing a mount command will now show the share mounted, just as if it were an NFS export:

Please see the manual pages for smbmount and smbumount for details on the above operation.

Access Windows 10 Samba Share from Linux commandline with minimal SMB2

Environment:

Linux X86 Server with Debian 9.3

kernel: Debian 4.9.65-3+deb9u1

smbclient: Version 4.5.12-Debian

Situation:

Backupserver ( backuppc ) has to backup a Windows 10 Home client.

Alternative:

Cygwin/Rsync used for other Win7 Clients rejected because of manual work involved.

Prerequisites known already:

DNS entry for Win10Client: done, tested and working

DHCP entry for Win10Client: done, tested and working

SMB1 is unsecure so do not go the «easy way».

The smbclient supports SMB2/3 protocol so i should not have to set the smb1 registry hack to enable SMB1 from e.g.

Problems: I cannot mount the administrative or any other share, nor do I see them with smbtree -b -N

What I have tried:

I tried to use the non-administrative share (no $ at the end)

I renamed the administrative share from C$ to mC$ or mC .

Added a test share in documents.

Added a test share in C:\test

None of those are visible via smbtree .

Directly connecting to the shares (or get a list of shares):

How do i get this working with either SMB2 or SMB3 protocol?

1 Answer 1

The Answer to howto includes multiple parts as the situation might be a bit different depending what you need.

I included everything i found (or believe to have found) via the various searches which helped me fix my direct problem.

The default Debian 9 Stretch Kernel does not support SMB3

Turns out my kernel seems to not support SMB3 directly

From my research it is not in the stretch backports either (cifs-utils to support the kernel change from 4.11?)

However i am unsure on the backport part as there are newer kernels but for my case i will not upgrade to the backport kernel for this feature so i stopped here.

smbtree needs more parameter to work with SMB3

It was not immediatly clear to me how to get smbtree working with SMB3, and with the issue i though to found out above i dropped the idea for SMB3 altogether.

smbclient does not use SMB2 or SMB3 per default.

The default version for the smb protocol for smbclient is

SMB1

This is not supported per default in Windows 10.

If you need this for your use case you have to add the corresponding registry key:

HKLM:\SYSTEM\CurrentControlSet\Services\LanmanServer\Parameters\SMB1 (Type DWORD32, value 1 for on, 0 for off)

You might have to change the file-sharing encryption-level in Windows 10 to get SMB1 working as well:

as i did not test this directly i do not know if it is actually needed :

see for example how to do this from here:

To Change File Sharing Encryption Level in Network and Sharing Center

Open the Control Panel , and click/tap on the Network and Sharing Center icon.

Click/tap on the Change advanced sharing settings link on the left side. (see screenshot below)

Expand the All Networks network profile.

Under File sharing connections, select «Enable file sharing for devices that use 40- or 56-bit encryption»

Working commands

Now to get actualy things working

changing the smbclient command

lets you view the shares of that client.

As mountparam for console to actually access it:

or as /etc/fstab entry (no automount on boot!)

Administrative Share

For the administrative share you have to do one additional registry change (if you are not in a domain):

taken from here :

basically what it does is disable the UAC for remote share access and maintenance, so be careful about it.

This might help understand the implications better, so be certain if you actually want to do this:

backuppc Issues:

You will want another account specific for backuppc which has to have read permissions for the share.

backuppcs smbclient default options do not include -m SMB2

The command backuppc uses is:

change that to include -m SMB2

After that i still got NT_STATUS_ACCESS_DENIED:

doing it manually with password added after the -U

removing the -N promts me the password with which it works as well.

As i did not want to store it within a configuration file from backuppc i will in the final version use the credential method.

After trying to figure out what the difference between the backuppc command and smbclient command manually was i figured out that the -N results in different behaviour during connection.

working solution without -N (with username password or credential file, did not matter. Non-administrativ or administrative share did not change anything either)

Domain=[CLIENTNAME] OS=[] Server=[] . cut

Non-working Version with -N :

Backuppc Win10 Client working solution

Given all above information i am able to backup the Win10 adminstrative share with following backuppc options:

How to share files between a Linux and Windows computer

The easiest and most reliable way to share files between a Linux and Windows computer on the same local area network is to use the Samba file sharing protocol. All modern versions of Windows come with Samba installed, and Samba is installed by default on most distributions of Linux.

Create a shared folder on Windows

First, create a shared folder on your Windows machine.

1. Open the Control Panel.
2. Go to Network and Sharing Options.
3. Go to Change Advanced Sharing Settings.
4. Select Turn on Network Discovery and Turn on File and Print Sharing.

Now, create a new folder to share or choose an existing folder that you’d like to share.

1. Right-click the folder and select Properties.
2. Go to the Sharing tab.
3. Above the Share button is the network name of the share you are creating. It should look like \\YOURCOMPUTERNAME\Users\YourUserName\ShareFolderName. Make a note of this network name to use later on your Linux machine.
4. Click Share.

Access a Windows shared folder from Linux, using Konqueror

Many Linux distributions use the KDE desktop environment and the Konqueror file manager/browser. If this is what you are using, you can follow these steps to access your Windows shared folder:

1. Click the K menu icon.
2. Select Internet ->Konqueror.
3. In the Konqueror window that opens, click the Network Folders link, or type remote:/ in the address bar and press Enter .
4. Click the Samba Shares icon.
5. Click the icon of your Windows Home workgroup.
6. Click the Workgroup icon.
7. Click the icon for your computer.
8. When prompted, enter the username and password for the Windows account that created the share.
9. Click OK.

Access a Windows shared folder from Linux, using Nautilus

Many Linux distributions, especially those that use the GNOME desktop environment, use the Nautilus file manager. If this is what you’re using, you can follow these steps to access your Windows shared folder:

1. Open Nautilus.
2. From the File menu, select Connect to Server.
3. In the Service type drop-down box, select Windows share.
4. In the Server field, enter the name of your computer.
5. Click Connect.

Alternatively, in the Nautilus address bar, you can type smb://ComputerName/ShareName and press Enter . For instance, when you created your Windows Share, if the share name was listed as:

Type smb://YOURCOMPUTERNAME/Users/YourUserName/ShareFolderName and press Enter . Note the smb: at the beginning; in Linux, use forward slashes instead of backslashes.

Access a Windows shared folder from Linux, using the command line

You can also access your Windows share from the Linux command line using the smbclient program.

1. Open a terminal.
2. Type smbclient at the command prompt.
3. If you receive a «Usage:» message, this means smbclient is installed, and you can skip to the next step. If the command is not found, however, you need to install smbclient. Follow these steps to install it.

Ubuntu Documentation

Client Access — Browsing SMB shares

The samba package is a meta-package intended to be installed on file and printer sharing servers. Clients do not need this meta-package (you are acting as a client if you need to access files on another computer). For example, installing samba is not necessary if you only need your Ubuntu system to do any of the following:

Access shared folders, drives and printers on a Windows computer (that is, act as a client with Windows servers). To do this, you only need the smbfs plugin. See MountWindowsSharesPermanently for more information.
Have your Windows computer use (via a network) a printer that is attached to a Linux computer. CUPS can be configured to make the printer accessible to the network.

Share directories between two Linux computers. You can use NFS or setup an SSH server on one computer and access it from other computers using an scp or sftp client, or Places -> Connect to Server. and choose «SSH» as the service type.

Ubuntu Clients

Ubuntu and Gnome make it easy to access files on a Windows network share. Open the Places Menu, then click on Network. You will see a Windows network icon. Double-click to open it. The next window shows all the domains/workgroups found on your network. Inside each domain/workgroup you will see all the computers on the domain/workgroup with sharing enabled. Double-click on a computer icon to access its shares and files.

If you want to be able to share folders with nautilus (the file browser), install the nautilus-share package (installed by default in Ubuntu 9.10 Desktop edition):

Alternate: From the menu at the top select «Location» -> «Connect to a server». In the «Service type» pull down select «Windows share». Enter the server ip address in the «Server:» box and the share name in the «Share:» box. Click «Connect» and then «Connect» again on the second dialog box

Alternate 12.04: Double clicking on ‘Windows network’ did not work for me. So I went to ‘Go’ menu in the nautilus file browser and clicked ‘Location’. I got an address bar at the top of the window. I entered «smb://192.168.2.148» (substitute the IP address of your Samba server) — I was presented with user/password window — After typing in user/passwd I was able to see the samba shares on the server and browse the files/folders.

Note: The default installation of Samba does not synchronize passwords. You may have to run «smbpasswd» for each user that needs to have access to his Ubuntu home directory from Microsoft Windows.

Windows Clients (XP,Server,Vista, Win7)

Microsoft Windows clients connect and browse through their corresponding network interface.

Example: XP clients can open Windows Network Neighborhood or My Network Places to browse available SMB shares.

Samba Client — Manual Configuration

This section covers how to manually configure and connect to a SMB file server from an Ubuntu client. smbclient is a command line tool similar to a ftp connection while smbfs allows you to mount a SMB file share. Once a SMB share is mounted it acts similar to a local hard drive (you can access the SMB share with your file browser (nautilus, konqueror, thunar, other).

Connecting to a Samba File Server from the command line

Connecting from the command line is similar to a ftp connection.

List public SMB shares with

Connect to a SMB share with

Enter you user password.

You can connect directly with

but your password will show on the screen (less secure).

Once connected you will get a prompt that looks like this :

Type «help» , without quotes, at the prompt for a list of available commands.

Connecting using CIFS

CIFS is included in the smbfs package and is a replacement for smbfs (I know, the terminology here is a little confusing).

As above, install by any method, smbfs, on Ubuntu 12.10, smbfs has been replaced by cifs-utils.

Allow non-root users to mount SMB shares

By default only root may mount SMB shares on the command line. To allow non-root users to mount SMB shares you could set the SUID, but I advise you configure sudo. You should configure sudo with visudo

You may either allow the group «users» to mount SMB shares, or add a group, samba, and add users you wish to allow to mount SMB shares to the samba group.

Change «user» to the username you wish to add to the samba group.

In the «group» section add your group you wish to allow to mount SMB shares

Change «%samba» to «%users» if you wish to allow members of the users group to mount SMB shares.

The following will mount the myshare folder on myserver to

/mnt (it will be in your home directory):

Note : «samba_user» = the user name on the samba server (may be different from your log-in name on the client).

The «noexec» option prevents executable scripts running from the SMB share.

You will be asked for BOTH your sudo and then your samba_user password.

Automagically mount SMB shares

In order to have a share mounted automatically every time you reboot, you need to do the following:

With any editor, create a file containing your Windows/Samba user account details:

KDE users must use kdesu rather than gksu and instead of Gedit they can use Kwrite as editor.

. it should contain two lines as follows:

Note : «samba_user» = the user name on the samba server (may be different from your log-in name on the client). «samba_user_password» is the password you assigned to the samba_user on the samba server.

Save the file and exit gedit.

Change the permissions on the file for security:

Now create a directory where you want to mount your share (e.g. /media/samba_share):

Now, using any editor, and add a line to /etc/fstab for your SMB share as follows:

Add a line for your SMB share:

The share will mount automatically when you boot. The «noexec» option prevents executable scripts running from the SMB share.

To mount the share now, without rebooting,

You can unmount the share with :

If you wish to increase security at the expense of convenience, use this line in /etc/fstab

The noexec» option prevents executable scripts running from the SMB share.

Edit /etc/samba/user, remove the password (leave just the samba user).

Now the share will NOT automatically mount when you boot and you will be asked for your samba password.

Mount the share with :

CIFS may cause a shutdown error.

Connecting using SMBFS (deprecated)

Note : This method still works, but as outlined under the «CIFS» section above is «deprecated» (no longer maintained and pending removal from the kernel).

Mounting a share on the local filesystem allows you to work around programs that do not yet use GnomeVFS to browse remote shares transparently. To mount a SMB share, first install smbfs:

To allow non root accounts to mount shares, change the permissions on the smbmnt program thus:

Note : This may be a security risk as after setting the SUID bit anyone can mount a SMB share. I advise you configure sudo, as above.

The working line in /etc/sudoers is as follows (see CIFS section above):

This allows any user in the samba group to mount SMB shares (you will need to create a samba group and add users).

The following will mount the myshare folder on myserver to

/mnt (it will be in your home directory):

In order to have a share mounted automatically every time you reboot, you need to do the following:

Open a shell as root

Create a file containing your Windows/Samba user account details:

. it should contain two lines as follows:

Change the permissions on the file for security:

Now create a directory where you want to mount your share (e.g. /mnt/data):

Now edit the file system table (/etc/fstab) and add a line as follows:

. where ‘bob’ is the non-root user you log into ubuntu with, ‘server’ is the name or address of the Windows machine and ‘share’ is the name of the share.

To mount the share now, just use the following command as root. It will mount automatically on subsequent reboots.

to be continued.

Ubuntu Client

On the Ubuntu client using the menu at the top, go to «Places» -> «Network». You will see an icon «Windows network» and should be able to browse to your shared folder. You will be asked for a password, leave it blank. Click the «Connect button.

(no need for a password).

If you would like to mount your SMB share using your (server) hostname rather than the IP Address, edit /etc/hosts and add your samba server (syntax IP Address hostname).

Where «hostname» = the name of your samba server.

Windows Client

On Windows open «My Computer» and navigate to «My Network Places». Navigate to your Ubuntu server and your share will be available without a password.

Alternate : From the menu at the top select «Tools» -> «Map Network Drive». Select an available letter for your SMB share (Default is z: ). In the «Folder:» box enter \\samba_server_ipaddress\share. Tic (Select with the mouse) the option «Reconnect at login» if you want the share to be automatically mounted when you boot Windows. Click the «Finish» box. A dialog box will appear, enter your samba user name and password. Click «OK».

If you would like to mount your SMB share using your (server) hostname rather than the IP Address, edit C:\WINDOWS\system32\drivers\etc\hosts and add your samba server (syntax IP Address hostname).

Where «hostname» = the name of your samba server.
