JupyterHub is a multi-user notebook platform that authenticates real Linux (PAM) users and spawns each one a private, cgroup-isolated JupyterLab server via systemdspawner. Unlike bare JupyterHub AMIs that ship the Hub on an open port with no TLS and no configured authenticator or per-user isolation, this Lynxroute build is ready out of the box: PAM login with an admin password generated at first boot, host nginx terminating TLS on port 443 with the Hub bound to loopback only, per-user systemd cgroup isolation, one-command HTTPS via Certbot, UFW firewall pre-configured, and a CIS Level 1 hardened Ubuntu 24.04 LTS base.
BSD-3-Clause license - fully auditable, no vendor lock-in.
Overview
This is a repackaged software product wherein additional charges apply for hardening, security configuration, and support.
WHAT IS JUPYTERHUB
JupyterHub is a multi-user server for Jupyter notebooks: it gives each user their own, independent JupyterLab notebook server behind a single entry point. This build runs the Hub as a Python application (JupyterHub 5.5.0 with the JupyterLab 7 single-user server) and uses systemdspawner to launch every user's server inside its own systemd unit with cgroup isolation. Authentication is PAM, so users log in with their real Linux account password - no external identity provider required. The public-facing proxy (configurable-http-proxy) is bound to loopback and fronted by nginx for TLS. Per-user notebooks, kernels, and files persist on the instance disk. BSD-3-Clause license, no vendor lock-in. Self-hosted on your own EC2 instance, your notebooks and data never leave your AWS account.
WHAT THIS AMI ADDS
Security hardening:
- PAM authentication; an admin user with a strong password generated at first boot (written to /root/jupyterhub-credentials.txt)
- Login restricted to an explicit allow-list - new users are added deliberately, not open by default
- Each user's notebook server runs in its own systemd cgroup (systemdspawner) with a private temp directory
- The Hub and its proxy bind to 127.0.0.1 only; host nginx terminates TLS on port 443
- One-command HTTPS: certbot --nginx (Certbot and the nginx plugin are pre-installed)
- UFW firewall pre-configured (ports 22 and 443 only)
- fail2ban, auditd, AppArmor pre-configured
- CVE scan - every image is scanned for vulnerabilities before release
OS hardening (CIS Level 1):
- CIS Ubuntu 24.04 LTS Level 1 benchmark applied via ansible-lockdown
- auditd, SSH hardening, Kernel hardening, IMDSv2 enforced
Compliance artifacts:
- SBOM - CycloneDX 1.6 at /etc/lynxroute/sbom.json
- CIS Conformance Report at /etc/lynxroute/cis-report.html
- CIS Tailored Profile at /usr/share/doc/lynxroute/CIS_TAILORED_PROFILE.md
Highlights
- JupyterHub security baked in: PAM authentication with an admin password generated at first boot, each user's notebook server isolated in its own systemd cgroup, the Hub bound to 127.0.0.1 with host nginx terminating TLS on port 443, and login restricted to an explicit allow-list.
- CIS Level 1 hardened Ubuntu 24.04 LTS: auditd, fail2ban, AppArmor, SSH key-only, IMDSv2 enforced. CVE-scanned before every release. SBOM (CycloneDX) and CIS Conformance Report included.
- Multi-user data science out of the box: per-user JupyterLab servers with a Python 3 kernel, add accounts with a single adduser, one-command HTTPS via Certbot. BSD-3-Clause license - fully auditable, no vendor lock-in.

Amazon Machine Image (AMI)
An AMI is a virtual image that provides the information required to launch an instance. Amazon EC2 (Elastic Compute Cloud) instances are virtual servers on which you can run your applications and workloads, offering varying combinations of CPU, memory, storage, and networking resources. You can launch as many instances from as many different AMIs as you need.

Additional details
Usage instructions
- Launch instance (t3.large recommended; t3.medium minimum)
- Open Security Group - allow TCP 443 from your IP/CIDR (and TCP 22 for SSH)
- SSH: ssh -i key.pem ubuntu@<PUBLIC_IP>
- Read credentials: sudo cat /root/jupyterhub-credentials.txt
- Open https://<PUBLIC_IP>/ in your browser - accept the self-signed certificate warning. JupyterHub shows its login page.
- Log in as the admin user 'jupyteradmin' with the generated password from step 4. JupyterHub spawns your personal, cgroup-isolated JupyterLab notebook server.
- Add more users: create a Linux user (sudo adduser <name>), add the name to c.Authenticator.allowed_users in /etc/jupyterhub/jupyterhub_config.py, then sudo systemctl restart jupyterhub. Each user logs in with their own system password.
The admin password is generated at first boot and stored in /root/jupyterhub-credentials.txt. The Hub binds 127.0.0.1:8000 (loopback only); host nginx terminates TLS on port 443. Replace the self-signed TLS certificate with a CA-signed one for production use: sudo certbot --nginx -d yourdomain.com
