Solarwinds - Duplicate switch stackmembers

This is a follow up post to the switchstack sql code from last week. Recently, I noticed issues with my CPU stack member reporting, which showed duplicates. It turns out that there were duplicate entries in the SwitchStackMember table through some problems with Orion recently (don’t ask me the details, I’m not the admin). The problem resulted in the same node and stackswitches having several unique stack id’s in this table, thus being reported several times. [Read More]

Solarwinds - Monitoring switch stacks

Today’s post is on using SQL queries in Solarwinds to get more detailed information on the frontpage on stackswitches. Solarwinds tends to average the memory and cpu utilization among all switches in a stack, but this does not always reflect the true statistics on the switches. Sustained CPU above 80% can lead to data packets being dropped. The queries are all build in SWQL studio on a Solarwinds server to verify the information that is returned. [Read More]

Installing HomeAssistant ( on CentOS

In this piece we’ll be installing Home Assistant in Docker on CentOS. The reasons why I chose CentOS and how to set it up are described in the following posts: Set up a secure home server with CentOS - Part 1 Set up a secure home server with CentOS - Part 2: Samba Because of scalability and administratability, I’ve decided go to with Docker containers this time. My Pi already runs Hass. [Read More]

Set up a secure homeserver with CentOS - Part 2: Samba

Hey all, this is part 2 of setting up an CentOS server. For backup and accessibility, I always set up a Samba share. Samba is a filesharing protocol supported by Microsoft Windows, Linux and MacOS and I therefor prefer this type of fileshare over others in terms of compatibility. If you want to see other parts of this series: Set up a secure home server with CentOS - Part 1 Samba can be challenging to set up because of the complexity and the amount of configuration options, however, for the purpose of a homeserver, we’ll keep it simple.

Set up a secure homeserver with CentOS - Part 1

Hey all, In this post I want to take a look at setting up a secure home server with CentOS. Why CentOS and not the more common distros such as Debian? Well, I like the stability and leanness of CentOS and the the package manager is neat as well. Pretty much everything runs on this thing as easy as it does under Debian, but the added security and stability are a great plus. [Read More]

Ruckus Unleashed gateway mode setup: that thing Ruckus didn't tell you

Having problems setting up a gateway mode on Ruckus Unleashed access points that have a single RJ45 connector? You’re not the only one. During a test here in the office, I just found out that enabling Gateway Mode on the Unleashed Master during the setup makes it impossible to pair other new access points, even with Mesh enabled. The problem is that other new access points don’t have the meshing data just yet and since the master AP only possesses one UTP port, you cannot connect it any other way. [Read More]

Wireless network loop, point-to-point down

Hey all, Today one of my wireless networks pulled me a new one. I had basically created a loop in the network, but it took a while to figure this one out. I had noticed in the virtual SmartZone that the network of one of our APs had started to mesh differently from our design. So much so, that even management of some remote AP’s became a bit sluggish. The network is set up with several Ruckus P300 point-to-point AP’s to cover a large area and a couple of meshing AP’s in between. [Read More]

Ruckus Unleashed APs disassociate from their master AP

In my first, technical post, I’d like to go a bit more in-depth on a technical issue I’ve encountered in my work. Working with Ruckus products, I’ve had my fair share of experience and troubles with the new Unleashed series. Unleashed is a product series that integrates a selection of zonedirector features into the APs, to allow for a cheaper network deployment. Unleashed is limited to 512 simultaneous clients and a maximum of 25 APs in the network. [Read More]

Welcome to my blog

What to expect... or maybe not?

First of all, welcome to my new blog! I have finally found a new goal for this domain after keeping it around for years and small projects. My struggle with some of the issues and technologies in my work are time consuming to solve and I’m sure I’m not the only one. Some of the information I’ve found recently is not or poorly indexed in Google’s search engine and thus hard to find. [Read More]
