Great day getting @CoreLayerEU back on track with #automation and #iac. Used @HashiCorp #packer to create a new #vm template on #proxmox, followed by #terraform to create a set of #clones to prepare for an #k3s cluster. All stored in a #selfhosted #forgejo repository with credentials pulled on-the-fly from @1Password #cli.😍 Next steps: using @ansible and #k3sup by @alexellisuk to spin up the cluster and deploy @NetScaler #cpx for my presentation @DuCUG: "Alice in NetSc(k8s)ler land!"

Ever felt the anxiety of a single server being the lynchpin of your entire infrastructure? I recently tackled that challenge by building high availability into my HAProxy setup. Previously running a single HAProxy instance, I realized I was missing robust failover capabilities. The goal? Zero downtime and automatic recovery. I’ve detailed the journey from configuration to automated certificate syncing and testing in a new post. ➡️ archy.net/implementing-h… #HAProxy #HighAvailability #LoadBalancing #DevOps #Infrastructure #Automation #Resilience #SRE #Cloud #Cybersecurity

After being contacted by a couple of customers regarding the updates sent out by Nationaal Cyber Security Centrum (@ncsc_nl) regarding CVE-2025-5777 and CVE-2025-6543 for NetScaler, I've decided to bundle a set of tests for indicators of compromise into one #shell script. This script is based on one of my old #IoC scripts for CVE-2023-3419, combined with information from an article provided by my fellow former #CitrixCTP, @Deyda84. For more information, check the article at: jantytgat.com/posts/netscale… #netscaler #cve #ioc #security.

Microsoft announces the end of the #Appv exit at our #MADDAY. The client will remain in the operating system and the 2026 end date is off the table!

EUC ANNOUNCEMENT: EUC Uplugged is ON for 2025! This will be our final EUC Unplugged event- join us in Sedona AZ November 7-9 2025 for the final chapter! eucunplugged.com

New #blog post: Learn how to deploy @Citrix @NetScaler #VPX on #Proxmox jantytgat.com/posts/netscale… #CitrixCTP #NetScaler

🚨 Update 🚨 There is a new build that should fix the VPX Express licensing issues: 14.1 build 29.65. You can find the build under: Downloads --> NetScaler --> Virtual Appliances --> Citrix ADC VPX Release 14.1 --> 14.1-29.63 --> Citrix ADC Upgrade Package-14.1-29.65 (for VPX Express users only) #CitrixCTP

🚨🚨🚨 Beware of #NetScaler 14.1 build 29.63: This is a broken build for VPX Express!! 🚨🚨🚨 Fresh installs and upgrades from previous versions cause the license checks to fail on boot, rendering the appliance useless. Only the "EXPORT" variants of SSL ciphers are available. Proceed with caution on (licensed) production systems!! #CitrixCTP

🚨We automated our #wireguard server and clients, including a #watchdog script for #linux clients to monitor the connection! 🚨 github.com/corelayer/wire… #security #vpn #CitrixCTP

Op het komende @DuCUGevenement, op woensdag 18 september, vertelt @jantytgat ons alles over de configuration framework for @citrix NetScaler. Inschrijven: ducug.nl/evenementen/ci…

Providing exclusive benefits to your top-tier partners is understandable @citrix, but scrapping "Partner Use" and "Demo" licenses entirely for all partners except the Platinum tier is bonkers. So, how do you expect "Lighthouse" partners to learn and expand their expertise? Especially since we all know that many of these high-volume partners are simple box movers, I can't find the logic for this move...,

As the #EUC landscape changes, many previously unconsidered options become viable. Considering @Veeam has officially announced support for #proxmox, would you consider official support for #proxmox in @parallels #RAS a good idea? #RFE

@CoreLayerEU is now an official #Proxmox #Authorized #Reseller 🥳If you have questions migrating away from #VMware, get in touch!!

Our #ACME provider for @NetScaler DNS-01 challenges now supports #CNAME redirection, just in time for my #E2EVC session on #certificate management! @CoreLayerEU #CitrixCTP 🔥🥳

Finalized my bookings for #EUCUnplugged #Scottsdale and @E2EVC #Madrid. I will present at #E2EVC on the automation of certificates, specifically for @NetScaler. See you there?! #CitrixCTP @CoreLayerEU #LetsEncrypt #acme

PLS RT: Join our 55th @E2EVC, Madrid 3 May! 50 Sessions -> top folks in EUC on @parallels @ControlUp @XenServer @Nutanix AHV, Proxmox, AWS & @Citrix! Tapas & Beers & Networking! Updates on @uberAgentApp, MSIX from @TimothyMangan, Security @VDIHacker etc. e2evc.com

Sneak preview: our cross-platform @NetScaler ADC Administration tool is coming soon! Initial features include #backups, #acme #certificate request/renewal, and firmware push/cache. #golang @charmcli #bubbletea @CoreLayerEU #CitrixCTP

In @NetScaler #podcast episode 3, @jantytgat talks about the power of content-switching for traffic management and security posture in the modern application delivery landscape. youtu.be/KTNZC_1Z4-w?si…

@NetScaler has issued a security bulletin concerning CVE-2023-4966 and CVE-2023-4967. Update as soon as possible to the latest releases (13.0, 13.1 and 14.1 are impacted). Remember that 12.1 is EOL!! Happy patching all! #CitrixCTP #NetScaler @CoreLayer support.citrix.com/article/CTX579…

Let's Encrypt for #NetScaler v0.40 is released: support for environment variables, support for Sectigo/DigiCert certificate authorities through #ACME protocol, and support for many DNS providers is now in GA. Check the updated documentation for more info! github.com/corelayer/nets…
