RUT955 USB Tools

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 access to connected storage drives or individual directories contained in those drives. A shared directory must be added before it can be configured:

field name	value	description
Name	string; Default: none	Name of the shared directory.
Path	file path; Default: none	Path to the shared directory. To share an entire drive, choose an automatically generated path from this drop-down box (for example, /mnt/sda1). To share a specific directory on the drive, specify the full path to that directory (for example, /mnt/sda1/shared/video)
Allow guests	yes | no; Default: no	Enables guest access, which allows anonymous connections to the shared directory
Allowed users	string; Default: none	Defines which users can access the shared directory. Users can be created from the Samba user tab (refer to section 2.3 for details). If Allow guests is checked, this field becomes inactive
Read-only	yes | no; Default: no	Makes the directory read-only, which means the shared directory can only be accessed to view and read files
Delete	- (interactive button)	Deletes the configuration related to the shared directory

Samba Users

---

Samba users are users that can be granted access to shared directories (as described in section 2.2.1. To add a new user, enter a custom username and password and click the add button:

field name	value	description
Username	string; Default: none	Name of the new user
Password	string; Default: none	Password of the new user

Printer Server

The Printer Server provides the possibility to configure access to a printer that is connected to the USB port of the RUT955 device. The Add button lets you add and manage additional printers. To configure a printer instance, click the Edit button located next to it:

field name	value	description
Enable	yes | no; Default: no	Turns support for the printer ON or OFF
Device	Default: none	Selects the printer
Port	integer [9100..9109]; Default: 9100	TCP listener port
Bidirectional mode	yes | no; Default: no	Turns bidirectional mode ON or OFF

Supported USB modems

RUT955 also supports the following USB modems:

• Huawei MS2131i-8
