Automount (en)

- in Deutsch

- in English

The Automounter is a service (consisting of automount/autofs), to mount file systems automatically. Mounting is performed when accessing the configured directories. Unmounting is performed by default after 5 sec. of inactivity (depending on the used image). On Dreamboxes the service is used to access network shares. The shares can be accessed over cifs and/or nfs.

After mounting the share it's possible to play supported movies, music and images. The network shares can be on Dreamboxes, Linux computers, Macs, NAS and Windows computers.

Advantage of the automounter: no scripts, editing of the fstab or boot settings are required.

Functionality Automounter

For the preamble Automount Mounter, two files are important, autofs and automount. Autofs defines the mount points using the auto.master file. Afterwards the mounting is performed by automount.

Goal of the article

• Learn the configuration of the Auto Mounter

Prerequisites

• Knowing the Blue Panel (Automount - Editor) and the remote control
• Editing the configuration file with an unix compatible editor

Configuring the Automounter

There are 3 ways to configure the automounter.

• The Automount Editor of the BluePanel
• Or editing the configuration file
• With the GP3 Plugin and the installed Netscan Plugin, Samba and NFS shares can be found and passed to the Automount Editor.

Configuration via Automount Editor

The Automount Editor is available in Enigma since Gemini Project 1.9 and in Enigma2 since Gemini Project 3.2 in the Blue Panel.

• With Enigma (since version 4.5) the Automount-Editor can be found in the Blue Panel under Extras / Settings => Automount
• With Enigma2 (since version 4.1) under Settings => Automount Editor
• With the installed GP3 Plugin under Blue Panel => Settings => Automount Editor

After configuring the mount point, the box or the autofs Daemon needs to be restarted. When using the Automount Editor of the GP3 Plugin, this is no longer required. After closing the editor, autofs is restarted automatically.

description of the settings

Name
Enter the name of the device (e.g. sound). The autofs daemon creates a directory with the selected name.
The path of the directory is saved in the file auto.master.
Read: Accessing the mount point.

Attention: if using multiple mounts, the name (mount point) should always be different.

Typ
selection of the protocol CIFS.

Parameter
Options for the mount.

Server
IP address of the source device.

Share
Enter the name of the shared directory.
Attention, with Enigma2 there shouldn't be a / (Slash) entered at the beginning!

read / write buffer
The options rsize and wsize define the size of the data packages, which are exchanged by the client and server.

User
Enter the user name of for the access on the source device.

Password
Enter the password for the access on the source device.

Charset (utf8)
Sets the character encoding onto utf8, useful for special characters.

Accessing the mount point

The access of the created mount point depends on the Gemini version. The easiest way is to use the File Mode (Enigma), or the File Manager (Enigma2).

• For Enigma boxes the mount point can be found in the directory /automount.

• For Enigma2 up to GP version 3.8 the mount point is in /automount. From version 3.9 till 4.1 it can be found in /autofs. And from GP2 4.2 until GP3.2 in /media/net.

• Since Gemini Project 3.3 for OE 2.2 the mount points are in /media/network.

Configuration via configuration file

The configuration file of the automounter for CVS Boxes can be found in /var/etc and for OE Boxes in /etc (CVS/OE Boxes see here). Here you can find also the different files depending on the image version. The syntax remained the same.

• With Enigma the file name is automount.conf. The configuration is possible since Gemini Project 3.1.

• With Enigma2 the file name is automount.conf for Gemini Project 1.8 - 3.8. Since version 3.9 - 4.1 the file name is auto.hotplug. And from version 4.2 until GP 3.2the name is auto.network.

• Since Gemini Project 3.3 for OE 2.2 the file name is auto.gemini.

The permissions with OE 2.0 / OE 2.2 images should be 644. The file shouldn't be executable! You can change the permission with the command chmod 644 /etc/auto.network.

After the creation of a mount point, the Box or the autofs daemon should be restarted.
