Linux samba client mount

Как в Linux монтировать шару CIFS

Обновлено: 01.05.2023 Опубликовано: 18.07.2016

Что такое Linux и CIFS простыми словами. Работа с общими папками Windows происходит с использованием протокола CIFS (SMB). Все примеры в данном руководстве выполняются на Linux Ubuntu и CentOS.

Подготовка

Установка пакетов

Сетевые порты

Синтаксис

* вместо mount.cifs можно написать mount -t cifs.

mount.cifs //192.168.1.1/public /mnt

* простой пример монтирования папки public на сервере 192.168.1.1 в локальный каталог /mnt.

Если нам не известны расшаренные папки на сервере, мы можем воспользоваться утилитой smbclient. Для начала установим ее.

а) на RPM (Rocky Linux / РЕД ОС / Red Hat / CentOS / Fedora):

б) на Deb (Debian / Ubuntu / Astra Linux / Mint):

или, при необходимости авторизоваться на файловом сервере:

smbclient -L 192.168.1.1 -U username

Ручное монтирование

Теперь монтирование можно выполнить следующей командой:

mount.cifs //192.168.1.10/share /mnt -o user=dmosk

* в данном примере будет примонтирован каталог share на сервере 192.168.1.10 в локальную папку /mnt под учетной записью dmosk.

То же самое, с использованием домена:

mount.cifs //192.168.1.10/share /mnt -o user=dmosk,domain=dmosk.local

Автоматическое монтирование CIFS через fstab

Для начала создаем файл, в котором будем хранить данные авторизации при подключении к общей папке:

И добавляем в него данные следующего вида:

username=dmosk
password=dPassw0rd
domain=dmosk.local

* в этом примере создана пара логин/пароль — dmosk/dPassw0rd; domain указывать не обязательно, если аутентификация выполняется без него.

Задаем права на созданный файл, чтобы доступ был только у пользователя, скажем, root:

chown root:root /root/.smbclient

Теперь открываем конфигурационный файл fstab:

и добавляем в него следующее:

//192.168.1.10/share /mnt cifs user,rw,credentials=/root/.smbclient 0 0

* в данном примере выполняется монтирование общей папки share на сервере с IP-адресом 192.168.1.10 в каталог /mnt. Параметры для подключения — user: позволяет выполнить монтирование любому пользователю, rw: с правом на чтение и запись, credentials: файл, который мы создали на предыдущем шаге.

Чтобы проверить правильность настроек, вводим следующую команду:

Примеры использования опций

Версии SMB

Если на стороне Windows используется старая или слишком новая версия протокола SMB, при попытке монтирования мы можем получить ошибку mount error(112): Host is down. Чтобы это исправить, указываем версию:

mount.cifs //192.168.1.10/share /mnt/ -o vers=1.0

* монтирование по протоколу SMB1.0

Монтирование от гостевой учетной записи

Если сервер принимает запросы без логина и пароля, то клиент подключается, как гость:

mount.cifs //192.168.1.10/share /mnt -o guest

//192.168.1.10/share /mnt cifs guest 0 0

Права на примонтированные каталоги

При монтировании папки мы можем указать определенные права:

mount.cifs //192.168.1.10/share /mnt -o file_mode=0777,dir_mode=0777

Для указания владельца, который будет назначен для примонтированного каталога, используем:

mount.cifs //192.168.1.10/share /mnt -o uid=33,gid=33

* чтобы посмотреть идентификаторы пользователя, вводим id -u и id -g .

Client Access — Browsing SMB shares

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

smbclient -L //server -U user

Connect to a SMB share with

smbclient //server/share -U user

You can connect directly with

smbclient //server/share -U user%password

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.

sudo groupadd samba sudo adduser user samba

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

Add a line in the "group" section : ## Members of the admin group may gain root privileges %admin ALL=(ALL) ALL %samba ALL=(ALL) /bin/mount,/bin/umount,/sbin/mount.cifs,/sbin/umount.cifs

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):

mkdir ~/mnt sudo mount -t cifs //myserver_ip_address/myshare ~/mnt -o username=samb_user,noexec

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:

username=samba_user password=samba_user_password

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:

sudo chmod 0400 /etc/samba/user # permissions of 0400 = read only

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

sudo mkdir /media/samba_share

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

sudo cp /etc/fstab /etc/fstab.bak gksu gedit /etc/fstab

Add a line for your SMB share:

//myserver_ip_address/myshare /media/samba_share cifs credentials=/etc/samba/user,noexec 0 0

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,

sudo mount /media/samba_share

You can unmount the share with :

sudo umount /media/samba_share

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

//myserver_ip_address/myshare /media/samba_share cifs noauto,credentials=/etc/samba/user,noexec 0 0

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.

sudo mount /media/samba_share

CIFS may cause a shutdown error.

CIFS VFS: Server not responding.

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:

sudo apt-get update sudo apt-get install smbfs

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

sudo chmod u+s /usr/bin/smbmnt /usr/bin/smbumount

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):

%samba ALL=(ALL) /bin/mount,/bin/umount,/sbin/mount.cifs,/sbin/umount.cifs,/usr/bin/smbmount,/usr/bin/smbumount

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):

mkdir ~/mnt smbmount //myserver/myshare ~/mnt

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

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

. it should contain two lines as follows:

username=george password=secret

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:

//server/share /mnt/data smbfs credentials=/etc/samba/user,rw,uid=bob 0 0

. 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.

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.

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.
