Setting Up Juniper Network Connect on Ubuntu: A Step-by-Step Guide for Linux Users 'download juniper network connect'

Introduction

---------

Juniper Networks' NetScreen/VPN concentrators are widely used to secure and manage remote access connections. For users running Linux distributions like Ubuntu, setting up Juniper's Network Connect client can sometimes be a challenge due to its dependency on Java's Native Interface (JNI) libraries for proper functioning.

In this article, we'll walk you through the process of downloading and installing Juniper Network Connect on 64-bit versions of Ubuntu Trusty Tahr (14.04 LTS), with special emphasis on overcoming common obstacles that may arise during the setup procedure.

Prerequisites

---------

Before proceeding, ensure your system meets these minimum requirements:

* Ubuntu Server/ Desktop version: Trusty Tahr (14.04) or later 64-bit architecture Java Runtime Environment (JRE) installed Oracle's Sun JDK / JRE for Linux downloaded and installed (optional but recommended)

Step-by-Step Instructions

-------------------------

### Step 1: Add Canonical Partner Repository

Open a terminal window as root user/ sudo privileged mode:

```bash

sudo apt-get update && sudo add-ppa ppa:webupd8team/java -y

```

This command updates the package index, adds the WebUpd8 Java PPA repository (which provides recent versions of java), and enables it for automatic updates.

### Step 2: Install Oracle's Sun JDK/ JRE

Optional but highly recommended:

```bash

sudo apt-get install oracle-java7-installer -y

```

This will download, compile, and configure the latest version of Java available from Oracle's official repositories. Note that you might need to use a different package name depending on your desired Java version (e.g., `oracle-jdk8` or `openjdk-9*`) if not using JDK.

### Step 3: Download Juniper Network Connect

1. Visit the 'Juniper Networks'(https://www.juniper.net/kyosai/en/landing.html?name=download-netscreen-vpn) download page and select 'Other Platforms' from the drop-down menu.

2. Click on 'Linux x86_64 RPM' to begin downloading the Network Connect client.

### Step 4: Install Juniper Network Connection Manager

```bash

sudo rpm -ivh juniper_network_connect-*.rpm --nohooks

```

Replace `juniper_network_connect-*` with actual filename of downloaded RPM package. This command will extract and install the necessary components, but do not start it yet.

### Step 5: Start Juniper Network Connect

```bash

sudo /opt/NetworkConnect/bin/ncc -silent & export PATH=$PATH:/opt/NetworkConnect/

```

This starts the NetScreen VPN client in silent mode (-s) and adds its installation directory to your system's search path for future convenience.

Troubleshooting Tips

----------------

### Issue 1: 'java.lang UnsatisfiedLinkError'

* Ensure you have Oracle's JDK/JRE installed as per Step 2 above.

* If using OpenJDK, try switching back to Sun/Oracle JRE or vice versa and re-run the installation steps.

### Issue 2: No Network Connection Established

1. Check if your network interface is properly configured in Network Manager under System Settings > Network.

2 Make sure that you have correctly entered all necessary authentication credentials (username/password) when prompted during the initial login process.

-------

By following these step-by-step instructions and troubleshooting tips, you should now be able to successfully set up Juniper's Network Connect client on your 64-bit Ubuntu Trusty Tahr system. Remember to keep both Java and Network Connect components updated regularly for optimal performance and security. Happy surfing!
