Downloading, Installing, and Connecting to Ivanti Remote Access VPN in Linux


NOTICE: Ivanti has rebranded the Pulse Secure client Ivanti Secure Access on Windows, MacOS, Android and IOS.  They have not yet rebranded the Linux client.  We will make references to both Ivanti and Pulse Secure in the below article as applicable.  In other 4Help articles we will use Ivanti.  Functionally the two clients are the same.

Introduction

Secure Sockets Layer (SSL) virtual private network (VPN) provides secure remote access from one machine to restricted/private resources across a public network. Virginia Tech's SSL VPN service referred to as “Remote Access VPN”, is a subscription-based service that allows a user to access Virginia Tech resources remotely across the globe. This service does not provide any end-to-end encryption to other services that are being accessed over VPN but does encrypt the traffic between your machine and the VPN device.

Supported Platforms

See Ivanti Secure Desktop Client Supported Platforms Guide for a list of supported operating systems and web browsers.

4Help does not support Linux installations. Due to the wide variety of Linux distributions, 4Help cannot provide any support beyond these basic instructions. We do not guarantee that they will work with your particular device or client.

For security reasons, we ask users to upgrade their machines to the latest version and update them periodically to receive any patches for vulnerabilities. Network Infrastructure and Services (NI&S) is unable to support operating systems that are no longer supported by the operating system manufacturer.

2-Factor Authentication

The Virginia Tech Remote Access VPN service requires 2-factor authentication. For more information, see Enrolling, Adding, Managing, or Removing a Duo 2FA Device.

Connection Options

Generally, a) - VT Traffic over SSL VPN is the recommended connection profile, since it provides access to all Virginia Tech resources and doesn't slow down internet traffic to services outside of Virginia Tech. For more information, see the Which Connection Profile Do I Use? section of Remote Access VPN Frequently Asked Questions.

Instructions

Download, Install, and Connect to VPN with the Pulse Secure client

Disclaimer: 4Help does not support Linux installations. Due to the wide variety of Linux distributions, 4Help cannot provide any support beyond these basic instructions. We do not guarantee that they will work with your particular device or client.

These instructions were created using Ubuntu. Instructions may differ for other distributions.

  1. Click one of the following links to download the Pulse installer appropriate for your version of Linux:
  2. Installation:
    • Note: The nss3-tools and net-tools are dependency packages required to successfully install the VPN client.  Use one of the following commands to install these dependency tools manually:

      • Ubuntu/Debian: sudo apt-get install libnss3-tools net-tools
      • RHEL/CentOS: yum install nss-tools net-tools

    • Install the VPN client using one of the following commands:

      • Ubuntu/Debian: Install the VPN client package using the command: sudo dpkg -i <package name>
      • RHEL/CentOS: Install the VPN client package using the command: sudo rpm -ivh <package-name>

    • The upgrade from the old VPN client to the new VPN client is not supported.  If you have an older version of the VPN client already installed use the following command to remove it prior to upgrading:

      • Ubuntu/Debian: sudo dpkg -r <package name>
      • RHEL/CentOS: sudo rpm -e <package name>

Alternate Client for Linux: OpenConnect

Disclaimer: 4Help does not support Linux installations. Due to the wide variety of Linux distributions, 4Help cannot provide any support beyond these basic instructions. We do not guarantee that they will work with your computer.

OpenConnect CLI:

If you prefer not to use Pulse Secure, the command line OpenConnect VPN client has been tested on Ubuntu and Linux Mint and verified working.  Just like the Pulse Secure client it still requires the use of a web browser to perform the authentication. But once authenticated the browser will automatically close and leave OpenConnect running in a terminal. 

A set of scripts have been created to manage the authentication and login to the VT VPN.  This script can be used as is, or modified by the user if they so choose.

  1. Please read the below README document for the instructions on setting up and running the OpenConnect CLI scripts:

  2. After reviewing the document the scripts can be downloaded from the following link:
  3. When you connect with these scripts you will see a browser window similar to that from the Pulse Secure step 4, subsection D, E and F.  Refer to those steps above for how to authenticate.
  4. To disconnect from the VPN use the keystroke Ctrl-C in the terminal window that OpenConnect is running in.
