Building a power conversion tool in Python

I’ve been doing less and less Python development since moving to a new company back in June. At my previous employer, I worked on Python command-line scripts and a custom-built web app fairly often that assisted with daily, monotonous tasks as well as troubleshooting. I really enjoyed the process of learning more about Python and developing tools that helped not just myself, but also my team.

LLDP and multi-gig speeds


So you’ve got that fancy new AP from VendorX with all the speeds and feeds, including multi-gigabit capability. Are you taking advantage of the increased speeds? How do you keep track of all your APs and the speeds they are linked up at? I found this interesting tidbit about LLDP when I was doing some investigation on an infrastructure insight that RUCKUS Analytics provides…

Manually scaling a floor plan

I was recently asked to do a predictive design for a warehouse. Sounds innocent enough, except the floor plan was a picture of the floor plan made in an Excel spreadsheet. Up until this point, I had never dealt with something like this, but it immediately reminded me of this exchange on Twitter between Eduard Petrov and Vasco Costa a day or two before receiving it:

Client fingerprinting is broken and no one seems to care

Client fingerprinting, in my opinion, is one of those features that many people don’t think about until they either need it, want it, or it’s broken. It’s not as sexy as other Wi-Fi security related topics such as 802.1X or micro segmentation and it’s certainly not going to prevent a client from operating correctly on the network if it’s not available (or can it?). However, it does help provide insight into your Wi-Fi client base which can be valuable in terms of knowing what device or devices are popular and making sure your Wi-Fi supports them well. Additionally, it is possible to tie access controls to clients by their device type which can affect what they are able to do on the network. With that said, it’s probably worth knowing how client devices are identified from their manufacturer down to the OS version and more importantly, the methods your Wi-Fi vendor uses to identify them. In this post, I’m going to discuss how client fingerprinting is done in general, how RUCKUS does it, and how one method of fingerprinting that we use today is changing due to security concerns.

“Say my name, say my name” ain’t just for Destiny’s Child

No, I’m not quitting my career as an IT professional to start a R&B group, but hopefully the title of my blog post captured your attention enough to get you here. Now let me explain.

Earlier this year, RUCKUS released SmartZone (SZ) 6.0. There were many new features and improvements like a completely redesigned web UI for example, but another minor feature made the cut as well: AP Hostname Advertisement
