NetScaler Unified Gateway – Native Receiver

NetScaler unified gateway is one of the great new features in NS version 11. If you’ve worked with some of the more advanced features, then you may be familiar with one of the more common requests: Make a NetScaler Gateway (CAG) the target vServer of a content switching vServer. Fortunately, this is exactly what Unified Gateway does – essentially, Unified Gateway is a content switching vServer with one of the possible target vServers as a non-addressable … Read more…

Intel NUC External Antenna

One of the primary uses for our Intel NUC is as a cable box replacement HTPC – so that means there’s always movies, recorded TV or live TV streaming to it over the network. In the past, I was able to direct wire and use the ethernet port giving 1Gbps speed which is more than enough. But now that we moved, that is no longer an option – fortunately, I installed an Intel AC-7260 wireless card … Read more…

Why I Dislike Comcast

Happy New Year!! And with the new year comes new internet\TV service for the house – actually, it isn’t completely new, it’s the same service, just at a different address. Who is the ISP you ask? Why, it’s Comcast. Admittedly, I am one of the outliers in their “median network usage” calculation between lab traffic, cloud backups, and (legitimate) streaming traffic – and I also probably know and care more about security and networking than a … Read more…

Citrix Storefront 3.x Configuration Tool

Anyone that has deployed Citrix StoreFront in the past has likely needed to manually edit the web.config files for either customizations or advanced functionality that simply wasn’t available in the StoreFront GUI. In fact, Citrix has released a ‘StoreFront web GUI Assistant‘ that allows you to import then modify the web.config files – it was updated October 30, 2015 to support StoreFront 3, but it really didn’t support any of the more advanced features, and … Read more…

Microsoft TMG EOL – Replace with Citrix NetScaler

As you may already know, Microsoft has decided to mark its Forefront Threat Management Gateway (TMG – formerly ISA Server) product as end of life. Primary development on it stopped back in September of 2012 and mainstream support ended in April of 2015.

The Citrix solution is known as Citrix Virtual WAN and it is a part of the CloudBridge product line – more information is available here. What is Virtual WAN exactly?

Enterprise IT Performance Monitoring: Agent & Agentless vs Goliath’s Intelligent Agent

The debate over enterprise monitoring solutions that use agentless technology VS those that use agent software has been around for as long as monitoring has existed, and I’m not going to cover it in great detail as there is nothing new: Agent monitoring: Able to gather numerous data points, including those not otherwise exposed Communication can be configured and secured Need to install, maintain an agent Additional software can introduce extra load Agentless monitoring: No … Read more…

Customize NetScaler 10

Customize NetScaler 10 I have been meaning to create this post for some time – when NetScaler 10.1 was released, there was some confusion around the best method to customize the interface. The previous method involved using scripts to copy the customized files at boot time – see http://support.citrix.com/article/CTX122271 for details. I know many people are already on NetScaler 11, but for those that have not yet upgraded and are still on 10.5 this should be … Read more…
