Citrix ADC autoscale in AWS with terraform and Azure Pipelines

Citrix has released a feature that makes it possible to autoscale your Citrix ADCs (previously NetScaler) in AWS using their Citrix Application Delivery Management. You can read more about this feature here. The overview from Citrix looks like this: We have been using the autoscale solution and to make it easier for everyone else to…



Useful Netscaler CLI commands, particularly for diagnostics/troubleshooting

Over the last couple of years of working with the Citrix Netscaler product I’ve been noting down Netscaler cmds that I’ve found useful in various scenarios. The list of cmds I have saved up is quite big now, and I figured it would be helpful for other Netscaler admins to know about some of these….



Installing and configuring SFTP server on Windows Server 2016

For a recent customer engagement we needed to provide internal and external users with the ability to upload/download files through SFTP to a specific backend-server. For security reasons we decided to tunnel the SFTP traffic through the customer’s Netscaler, and so for this setup you need to do some Netscaler configuration and then the actual…



Rewrite or delete Server header using Citrix ADC CPX

A few days ago, I wrote a blog post about Using Citrix ingress controller with Azure Kubernetes Service. In this post, I’m going to show how easy it is to use the Custom Resource Definitions from Citrix to replace the Server header in an HTTP response, as well as removing it completely. If you would…



Using Citrix ingress controller with Azure Kubernetes Service

I’ve had an Ansible playbook to deploy and configure Azure Kubernetes Service on GitHub for a while, and now I’ve gotten around to add Citrix ingress controller! You can read my other blogpost about the playbook here. Citrix has a Kubernetes controller to read ingress objects and their own CRDs (rewrite for example, which isn’t…



OpenID Connect token validation in Citrix ADC

I’ve previously written about how to use OpenID Connect in NetScaler and a way to use callouts to validate tokens. You can also use the function JWT_VERIFY_CERTKEY() but that requires that you (for now) keep the issuing certificate updated locally. Another way is to setup an OpenID Connect client (OAuth Action) on Citrix ADC and…



Citrix ADC and ADM automation using Ansible

I’ve been working with Ansible more and more and been learning a lot. It’s so much fun but I also think it can help others out there with their projects. I’ve published a few blog posts regarding a few different parts of how I automate Citrix ADC (NetScaler) and Citrix ADM (NetScaler MAS), and will…



Configure Stylebook configpacks using Ansible and Citrix ADM

I’ve created an Ansible playbook to deploy configpacks to Citrix ADC (previously Citrix NetScaler) using Ansible and Citrix ADM (previously Citrix NetScaler MAS). You add the configuration to the parameters and the playbook will add configpacks using the settings you’ve defined. Still a lot to do with this one, for example updating the configpack when…



Deploy Citrix ADM Stylebooks using Ansible

I’ve created an Ansible playbook to deploy Citrix ADM (previously Citrix NetScaler MAS) Stylebooks. It will upload the latest version of the stylebook, migrate existing configpacks that are using the older version and then remove the old version from MAS. There are still a lot to do with this playbook, for example handle parameters being…



Citrix ADC base configuration with Ansible and Citrix ADM

I’ve created an Ansible playbook to configure a base line on Citrix ADC (previously Citrix NetScaler) using Ansible and Citrix ADM (previously Citrix NetScaler MAS). The only thing you will have to do is change the parameters in the playbook and run it. The playbook has been published to Azure DevOps and can be found…
