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

---

The Samba functionality allows network sharing for specified directories.

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 work group

Shared Directories

---

In the Shared Directories section you can 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.

field name	value	description
Username	string; Default: " "	Name of the new user
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.

You can enable or disable the support for your printer with this panel. In order to add another printer, type in a name and click the Add button. To configure a printer, click Edit next to the printer in question.

field name	value	description
Enable	yes | no; Default: no	Toggles printer support ON or OFF
Device	Default: " "	Chooses the printer
Port	integer [9100..9109]; Default: 9100	TCP listener port
Bidirectional mode	yes | no; Default: no	Toggles bidirectional mode ON or OFF

Supported USB modems

RUT955 also supports the following USB modems:

• Huawei MS2131i-8
