Introduction

In this guide we outline how Naverisk can connect remotely to an SSH enabled device. This will allow you to securely manage devices such as routers and switches, allowing console connections to be made via SSH.

1.0 Prerequisites

In order to connect to a device via SSH tunneling you will need to ensure that:

  1. The device is being monitored by Naverisk via SNMP. Setting up SNMP devices is covered in the following guide, also available from the Naverisk Help section:   http://docs.naverisk.com/Resources/KnowledgeBase/SNMPDeviceManagement.pdf     
  2. The client device that has the SNMP probe installed must also have the Remote Control package installed. This is installed by default.
  3. The SSH port (default 22) on the device you are attempting to connect to must be enabled.

To connect a device using SSH you will also need an SSH client. We recommend PuTTY, which is a free to use SSH and Telnet client: https://www.chiark.greenend.org.uk/~sgtatham/putty/latest.html

Note: Please make sure that you add PuTTY to then network path on your machine.

2.0 Using SSH to Connect to your Device

Under the Devices tab, select the SSH enabled device which you would like to connect to, you will see the following options:

Click on the SSH text or icon and PuTTY will pop up:

3.0 Troubleshooting

Login prompt not displayed on the PuTTY dialog

  • Check if the port specified in the device details is correct.
  • Verify that the device shows as Connected in Naverisk
  • On the Probe device, use the command prompt to verify the target device is reachable via ping
  • Use an SSH client such as the portable version of PuTTY to test the SSH connection from the Probe device.
  • Verify that the Remote Control package is installed on the Probe device.
