Summary

This chapter is an overview of the USB Tools service in RUT955 routers.

Network Shares

The Network Shares section is used to manage Network-attached storage (NAS) such as USB drives, SD cards and hard drives. The router supports the following file system architectures:

  • FAT32*
  • NTFS**

* supports SD cards with a capacity of up to 32 GB
** NTFS support available from FW version RUT9XX_R_00.05.02 and newer

Mounted File Systems


The Mounted File Systems tab displays information on mounted USB drives and SD cards. To view an attached drive, connect it to the router and click the Refresh button:

field name description
Filesystem Name of the Linux filesystem. For better clarity, lets take a closer look at the filesystem name from the example above:
  • /dev - the directory of device files. Everything in the Linux filesystem is either a file or a directory; /dev is the location of device files. Every device is represented by a file in the /dev directory
  • sd - identifies block devices* (capable of carrying data)
  • a - the letter immediately after sd signifies the order in which the device was first found (a, b, c, ...)
  • 1 - signifies the partition on the device
So the full string /dev/sda1 denotes the first partition of the first block device
* SD cards will be identified as MultiMediaCard (MMC) devices and the identifier will begin with the mmcblk string instead of sd
Mount Point A mount point is a directory in the currently accessible filesystem on which an additional filesystem is mounted (i.e., logically attached). The /mnt directory and its subdirectories are intended for use as the temporary mount points for mounting storage devices. The mount point becomes the root directory of the newly added filesystem, and that filesystem becomes accessible from that directory
Available Amount of available memory in the mounted drive. This column also displays the total capacity of the drive
Used Amount of used memory in the mounted drive
Safely Remove Disk Unmounts the drive so that it becomes safe to disconnect from the router

SSH commands


Devices can be mounted or unmounted manually by using SSH commands.

Mounting

The mount command attaches a filesystem to the file hierarchy. The basic syntax for the command is:

mount -t type device dir

Where:

  • -t - the filesystem type. If this value is omitted, the command will try to determine the type automatically
  • device - file name of the device. Refer to section 2.1 for examples
  • dir - directory that will be used as the mount point for the device. Refer to section 2.1 for examples

Example command:

mount -t ntfs /dev/sda1 /mnt/sda1
Unmounting

The umount command detaches filesystem from the file hierarchy. he basic syntax for the command is:

umount device

Example command:

umount /dev/sda1

Using the umount command is analogous to clicking the "Safely Remove Disk" button. Therefore, the attached drive can be safely disconnected after using umount to detach it.

Samba


Samba is a software solution for using the Server Message Block (SMB) networking protocol, which provides shared file access between nodes on a computer network. The Samba tab in RUT955's WebUI is used to configure network access (look to section 2.2.1 for details) to storage devices connected to the router's MicroSD slot or USB connector.

field name value description
Enable yes | no; Default: no Toggles Samba ON or OFF
Hostname string; Default: Router_Share Name of the Samba server
Description string; Default: Teltonika_Router_Share Short server description
Workgroup string; Default: WORKGROUP Name of the server's workgroup

Shared Directories


The Shared Directories section is used to configure add directories that are to be shared and configure some usage parameters.

field name value description
Name string; Default: my_dir Name of the shared directory
Path file path; Default: /mnt/sda1 Path to the directory that is to be shared
Allow guests yes | no; Default: no If enabled, all users and guests can view the shared directory
Allowed users string; Default: " " Specifies users that are to be allowed to share this directory
Read-only yes | no; Default: no Makes the directory Read-only

Samba Users

This page is used to add new Samba users.

Password string; Default: " " Password of the new user

Printer Server

The Printer Server function allows you to configure and use a printer that is connected to the RUT955 device.
