Beginning with F5 NGINX Plus version R33, all customers are required to deploy a JSON Web Token (JWT) license for each commercial instance of NGINX Plus. Each instance is responsible for validating its own license status. Furthermore, NGINX Plus will report usage either to the F5 NGINX licensing endpoint or to the F5 NGINX Instance Manager for customers who are connected. For those customers who are disconnected or operate in an air-gapped environment, usage can be reported directly to the F5 NGINX Instance Manager. To learn more about the latest features of NGINX R33, please check out the recent blog post. Install or Upgrade NGINX Plus R33 To successfully upgrade to NGINX Plus R33 or perform a fresh installation, begin by downloading the JWT license from your F5 account. Once you have the license, place it in the F5 NGINX directory before proceeding with the upgrade. For a fresh installation, after completing the installation, also place the JWT license in the NGINX directory. For further details, please refer to the provided instructions. This video provides a step-by-step guide on installing or upgrading to NGINX Plus R33. Report Usage to F5 in Connected Environment To effectively report usage data to F5 within a connected environment using NGINX Instance Manager, it's important to ensure that port 443 is open. The default configuration directs the usage endpoint to send reports directly to the F5 licensing endpoint at product.connect.nginx.com. By default, usage reporting is enabled, and it's crucial to successfully send at least one report on installation for NGINX to process traffic. However, you can postpone the initial reporting requirement by turning off the directive in your NGINX configuration. This allows NGINX Plus to handle traffic without immediate reporting during a designated grace period. To configure usage reporting to F5 using NGINX Instance Manager, update the usage endpoint to reflect the fully qualified domain name (FQDN) of the NGINX Instance Manager. For further details, please refer to the provided instructions. This video shows how to report usage in the connected environment using NGINX Instance Manager. Report Usage to F5 in Disconnected Environment using NGINX Instance Manager In a disconnected environment without an internet connection, you need to take certain steps before submitting usage data to F5. First, in NGINX Plus R33, update the `usage report` directive within the management block of your NGINX configuration to point to your NGINX Instance Manager host. Ensure that your NGINX R33 instances can access the NGINX Instance Manager by setting up the necessary DNS entries. Next, in the NMS configuration in NGINX Instance Manager, modify the ‘mode of operation’ to disconnected, save the file, and restart NGINX Instance Manager. There are multiple methods available for adding a license and submitting the initial usage report in this disconnected environment. You can use a Bash script, REST API, or the web interface. For detailed instructions on each method, please refer to the documentation. This video shows how to report usage in disconnected environments using NGINX Instance Manager. Conclusion The transition to NGINX Plus R33 introduces important enhancements in licensing and usage reporting that can greatly improve your management of NGINX instances. With the implementation of JSON Web Tokens (JWT), you can validate your subscription and report telemetry data more effectively. To ensure compliance and optimize performance, it’s crucial to understand the best practices for usage reporting, regardless of whether you are operating in a connected or disconnected environment.

When managing web servers like F5 NGINX, it's crucial to understand the rules that govern HTTP headers—particularly which characters are allowed or disallowed in both header names and values. HTTP headers play a vital role in the communication between a client and server, carrying essential metadata such as content type, length, and caching policies. NGINX strictly enforces these rules to ensure compliance with HTTP/1.1, HTTP/2, and HTTP/3 protocols. Misconfigured headers or the use of improper characters can lead to a range of issues, including security vulnerabilities, degraded performance, or even rejected requests. One common security threat,HTTP Request Smuggling, exploits desynchronization between devices involved in handling the request, such as frontends, caching servers, load balancers, and web servers. These attacks rely on inconsistencies in how each device parses the request, enabling malicious actors to inject hidden or split requests. This article outlines the allowed and disallowed characters in HTTP request headers as enforced by NGINX, which I compiled throughcode review, test case review and manual testing for HTTP Smugglingon NGINX version "nginx/1.25.5 (nginx-plus-r32-p1)". If I missed something please let me know bycontacting the F5 SIRT. Allowed Characters Header Names Lowercase letters: (a-z) Uppercase letters: (A-Z) Allowed in HTTP/1.1 Disallowed in HTTP/2 and HTTP/3, which require lowercase. Digits: (0-9) Hyphen: (-) Underscore: (_)Allowed in all versions only ifunderscores_in_headers is enabled Colon: (:) Allowed only as a prefix inHTTP/2 and HTTP/3 pseudo headers. Header Values Printable ASCII characters: Characters from ! to ~, including digits, letters, punctuation, and symbols, are allowed. Space: (0x20) Allowed within the value. Horizontal Tab (HT): (0x09) Generally allowed within values but with exceptions in headers such as Content-Length and Host (details below). Disallowed Characters Header Names Control Characters: ASCII control characters (<= 0x20), including space and horizontal tab, are disallowed in header names. DEL (0x7f): The delete character is not allowed. Colon: (:) Disallowed in header names except forHTTP/2 and HTTP/3 pseudo headers. Uppercase Letters: (A-Z) Disallowed in HTTP/2 and HTTP/3 header names (must be lowercase). Special characters: Characters such as ()<>@,;:\"/[]?={} are implicitly disallowed as they don’t belong to any allowed category for header names. Header Values Null Character: (\0) Disallowed in header values. Line Feed (LF): (0x0A) Not allowed within the value and used only to terminate headers. Carriage Return (CR): (0x0D) Not allowed within the value, used for header termination. Control Characters (<= 0x20) with special conditions for Horizontal Tab (HT): Horizontal Tab (HT, 0x09): Disallowed in the Host header value in HTTP/1. Disallowed in the pseudo-header values in HTTP/2 and HTTP/3. Disallowed in the Content-Length header value in HTTP/1. Summary This list of allowed and disallowed characters provides an overview of how NGINX handles HTTP headers across different protocol versions. While HTTP/1.1 is somewhat lenient with uppercase letters and certain characters, HTTP/2 and HTTP/3 enforce stricter validation rules, particularly for header names. Understanding these restrictions ensures your server configuration remains compliant with protocol specifications and avoids potential issues with malformed headers.Automating F5 NGINX Instance Manager Deployments on VMWare
With F5 NGINX One, customers can leverage the F5 NGINX One SaaS console to manage inventory, stage/push configs to cluster groups, and take advantage of our FCPs (Flexible Consumption Plans). However, the NGINX One console may not be feasible to customers with isolated environments with no connectivity outside the organization. In these cases, customers can run self-managed builds with the same NGINX management capabilities inside their isolated environments. In this article, I step through how to automate F5 NGINX Instance Manager deployments with packer and terraform. Prerequisites I will need a few prerequisites before getting started with the tutorial: Installing vCenter on my ESXI host; I need to install vCenter to login and access my vSphere console. A client instance with packer and terraform installed to run my build. I use a virtual machine on my ESXI host. NGINX license keys; I will need to pull my NGINX license keys from MyF5 and store them in my client VM instance where I will run the build. Deploying NGINX Instance Manager Deploying F5 NGINX Instance Manager in your environment involves two steps: Running a packer build outputting a VM template to my datastore Applying the terraform build using the VM template from step 1 to deploy and install NGINX Instance Manager Running the Packer Build Before running the packer build, I will need to SSH into my VM installer and download packer compatible ISO tools and plugins. $ sudo apt-get install mkisofs && packer plugins install github.com/hashicorp/vsphere && packer plugins install github.com/hashicorp/ansible Second, pull the GitHub repository and set the parameters for my packer build in the packer hcl file (nms.packer.hcl). $ git pull https://github.com/nginxinc/nginx-management-suite-iac.git $ cd nginx-management-suite-iac/packer/nms/vsphere $ cp nms.pkrvars.hcl.example nms.pkrvars.hcl The table below lists the variables that need to be updated. nginx_repo_crt Path to license certificate required to install NGINX Instance Manager (/etc/ssl/nginx/nginx-repo.crt) nginx_repo_key Path to license key required to install NGINX Instance Manager (/etc/ssl/nginx/nginx-repo.key) iso_path Path of the ISO where the VM template will boot from. The ISO must be stored in my vSphere datastore cluster_name The vSphere cluster datacenter The vSphere datacenter datastore The vSphere datastore network The vSphere network where the packer build will run. I can use static IPs if DHCP is not available. Now I can run my packer build $ export VSPHERE_URL="my-vcenter-url" $ export VSPHERE_PASSWORD="my-password" $ export VSPHERE_USER="my-username" $ ./packer-build.sh -var-file="nms.pkrvars.hcl" **Note: If DHCP is not available in my vSphere network, I need to assign static ips before running the packer build script. Running the Packer Build with Static IPs To assign static IPs, I modified the cloud init template in my packer build script (packer-build.sh). Under the auto-install field, I can add my Ubuntu Netplan configuration and manually assign my ethernet IP address, name servers, and default gateway. #cloud-config autoinstall: version: 1 network: version: 2 ethernets: addresses: - 10.144.xx.xx/20 nameservers: addresses: - 172.27.x.x - 8.8.x.x search: [] routes: - to: default via: 10.144.xx.xx identity: hostname: localhost username: ubuntu password: ${saltedPassword} Running the Terraform Build As mentioned in the previous section, the packer build will output a VM template to my vSphere datastore. I should be able to see the file template in nms-yyyy-mm-dd/nms-yyyy-mm-dd.vmtx directory of my datastore. Before running the terraform build, I set parameters in terraform parameter file (terraform.tfvars). $ cp terraform.ttfvars.example terraform.tfvars $ vi terraform.tfvars The table below lists the variables that need to be updated. cluster_name The vSphere cluster datacenter The vSphere datacenter datastore The vSphere datastore network The vSphere network to deploy and install NIM template_name The VM template generated by the packer build (nms-yyyy-mm-dd) ssh_pub_key The public SSH key (~/.ssh_id_rsa.pub) ssh_user The SSH user (ubuntu) Once parameters are set, I will need to set my env variables. $ export TF_VAR_vsphere_url="my-vcenter-url.com" $ export TF_VAR_vsphere_password="my-password" $ export TF_VAR_vsphere_user="my-username" #Set the admin password for NIM user $ export TF_VAR_admin_password="my-admin-password" And initialize/apply my terraform build. $ terraform init $ terraform apply **Note: If DHCP is not available in my vSphere network, I need to assign static IPs once again in my terraform script before running the build. Assigning Static IPs in Terraform Build (optional) To assign static IPs, I will need to modify the main terraform file (main.tf). I will add the following clone context inside my vsphere-virtual-machine vm resource and set the options to the appropriate IPs and netmask. clone { template_uuid = data.vsphere_virtual_machine.template.id customize { linux_options { host_name = "foo" domain = "example.com" } network_interface { ipv4_address = "10.144.xx.xxx" ipv4_netmask = 20 dns_server_list = ["172.27.x.x, 8.8.x.x"] } ipv4_gateway = "10.144.xx.xxx" } } Connecting to NGINX Instance Manager Once the terraform build is complete, I will see the NGINX Instance Manager VM running in the vSphere console. I can open a new tab in my browser and enter the IP address to connect and login with admin/$TF_VAR_admin_password creds. Conclusion Installing NGINX Instance Manager in your environment is now easier than ever. Following this tutorial, I can install NGINX Instance Manager in under 5 minutes and manage NGINX inventory inside my isolated environment.
