Installing Jump on Ubuntu Server Latest

Jump is a web-based SSH client written in Go language. It makes it easier for system administrators to access remote servers securely. In this tutorial, we will guide you through the steps of installing Jump on an Ubuntu Server Latest.

Prerequisites

Before beginning with the installation, make sure the server has the following prerequisites:

  • Ubuntu Server Latest version
  • Access to the system as a root user or a user with sudo privileges
  • OpenSSL version is later than 1.0.1

Step 1 - Update System

First, update the system to the latest version using the following command:

sudo apt-get update && sudo apt-get upgrade

Step 2 - Install Required Packages

Jump requires the installation of the following dependencies to function correctly:

  • Git
  • Docker
  • Docker-compose

Use the following command to install the dependencies:

sudo apt-get install git docker docker-compose -y

Step 3 - Download Jump

The next step is to download Jump from the GitHub repository using the git clone command:

git clone https://github.com/daledavies/jump.git

Step 4 - Configure Jump

Navigate to the downloaded Jump directory using the cd command:

cd jump

In the docker-compose.yml file, change the following environment variables according to your system configuration:

  • JUMP_HOST - the IP or hostname of the system where Jump will run
  • JUMP_PORT - the port number of the Jump service, default is 8080
  • JUMP_HTTPS_CERT_FILE - the path to the SSL certificate file
  • JUMP_HTTPS_KEY_FILE - the path to the SSL private key file

To generate a self-signed SSL certificate, run the following command:

sudo openssl req -new -newkey rsa:2048 -days 365 -nodes -x509 -subj \
"/C=US/ST=State/L=City/O=Organization/OU=IT Department/CN=example.com" \
-keyout /etc/ssl/private/jump.key -out /etc/ssl/certs/jump.crt

Then, modify the docker-compose.yml file with the correct paths:

...
environment:
  - 'JUMP_HOST=<your server IP or hostname>'
  - 'JUMP_PORT=8080'
  - 'JUMP_HTTPS_CERT_FILE=/etc/ssl/certs/jump.crt'
  - 'JUMP_HTTPS_KEY_FILE=/etc/ssl/private/jump.key'
...

Step 5 - Start Jump

Use the following command to start the Jump service:

sudo docker-compose up -d

After a few moments, Jump should be running, and you will be able to access it through the web browser at https://<your server IP or hostname>:8080.

Conclusion

You have successfully installed Jump on Ubuntu Server Latest. Jump provides secure and easy remote access to your servers.
