Remote Access

Remote Access integration enables to use the TNA as a secure gateway to allow access and troubleshooting of devices that are connected to the same network as your TNA from evalink talos or by evalink talos support team.

A VPN connection is established between your PC and the TNA. The TNA acts as a secure point-to-point router and data is transparently transferred between the PC and the connected device. This means you can keep using your tools with no additional configurations.

The devices are connected to the TNA using an Ethernet cable to Eth0 or Eth1 interface on ipTNA4i or using Eth0 or USB to Ethernet Adapters on TNA Connect devices.

The serial devices are connected to TNAs using Serial Adapters or using the on-board RS-232 on TNA Connect devices.

info

Access level 4 is required to configure Remote Access.

Before you proceed with the configuration, ensure that you have successfully completed the steps outlined in both Download and Install evalink talos Driver and Enable Remote Access on the TNA Web Server.

To configure Remote Access parameters, do the following:

1. On the TNA Web Server, click on view_module Integrations from the top navigation menu and choose
   Remote Access

2. On the configuration page, configure the following settings:

Name	Description
Path	This defines the paths (Ethernet and/or Mobile) to be used for remote access. Paths can be prioritized, which means that the prioritized path is used by default and the other path is used as a backup depending on their order. The path order can be changed by dragging a given path and dropping it in the necessary position using the drag icon drag_indicator next to the path. Disabled paths are not used for remote access.
Ethernet Configuration	This section offers options to activate or deactivate remote access to specific Ethernet interfaces: Ethernet 0 and/or Ethernet 1. Once the connection is established, the TNA will attempt to reach the target device based on its subnet.
Switchover Delay	This parameter specifies the time delay, measured in seconds, before attempting to switch from the backup path to the primary path. Default value: 14400 Minimum value: 1 second Maximum value: 86400 seconds
Additional socat arguments	These are extra parameters appended to socat commands, specifically intended for remote access over serial. Maximum: 256 characters Example: vmin=32,vtime=1

3. Click on Save

4. (Optional) Click on Undo changes to reset the parameters to their previous values

5. (Optional) Click on Reset to default to reset the parameters to their default values

important

VPN connections require certain security certificates. If these certificates are not generated or are missing for some reason, the system will not attempt to reconnect to the VPN. This is a critical security measure, ensuring that connections are not established without the proper authentication and encryption safeguards.

Remote Access connection is stopped by default after 3 hours due to certificates expiration.

   The IP address should be in the subnet of Eth0 or Eth1 interfaces.

   

6. For Remote Access over Serial, click on Serial and configure the following parameters:

   

Name	Description
Speed	The speed at which data bits are sent. Default value: 38400
Data Bits	The Data Bits is the number of bits of data in each frame. Default value: 8
Stop Bits	The Stop Bits is the number of bits used to mark the end of a frame.
Parity	The Parity bit can provide a simple form of error detection. Possible values are: None: no parity bit is added to the data. Even: the parity bit is set to space 0 if the total number of data bits in the mark 1 state is even. Odd: the parity bit is set to space 0 if the total number of data bits in the mark 1 state is odd.
