FreeNAS – Upgrades and a corrupted USB stick
FreeNAS – Upgrades and a corrupted USB stick
Last week I decided it was probably time to finally upgrade my FreeNAS server from 11.2 U2 to 11.2 U7 as it was giving me rrdcache errors on shutdown and also ground to a halt when I was doing a large clonezilla backup of my machine.

Citrix – Making CentOS Look Like Windows 10
As part of my testing with the CVAD 1912 Linux VDA I came across the B00merang desktop themes which makes a Linux desktop look like Windows 10. I decided to explore whether the theme could be applied to Citrix sessions and after to some googling, got it up and running .

Citrix – Learning About The Linux VDA
Citrix – Learning About The Linux VDA
As part of taking the new Citrix Virtual Apps and Desktops (CVAD) LTSR release out for a spin, today I decided to look at the Linux VDA again. It’s been a while since I tried it as my previous attempts weren’t successful but today I figured was the day to try again !
Many years ago I worked on a Citrix install for a school in Hull which used XenApp on Sun Solaris to provide Open Office to their students at home for doing their homework. At the time I was greatly impressed but after putting a XenApp server on Solaris in for one of the previous companies I worked for, I haven’t seen anything *nix related since.
Citrix ADC Vulnerability CVE-2019-19781
Citrix ADC Vulnerability CVE-2019-19781
Last Wednesday I got an update email from the Citrix Heroes community ran by DJ Eshelman about a new vulnerability which has been found with Citrix ADC appliances. Fortunately my home lab hasn’t been powered up much this past few weeks but today I decided to apply the mitigation steps to my VPX in case.

pfSense – Learning And Making My Life Harder !
I’ve been using pfSense as the firewall for my home virtual lab for many years and it has increased me knowledge of firewalls by giving me one to play with in my own environment. As a consultant it’s proved invaluable for me in my job as it’s allowed me to quickly test what ports are needed to be opened for various applications, work out routing roulette issues I’ve seen on site, and even simulate setting up Active Directory Domain Trusts over an IPSec VPN.

Nagios Pi Part Four
Nagios Pi Part Four
Since my last post I decided to concentrate on looking in to setting up distributed monitoring with Nagios Core servers and using my Nagios Pi installation as the central server. I looked around at the various options and went for using NRDP (Nagios Remote Data Protocol) as it enables me to use passive checks on the central server.

Nagios – Changing The Default Page
Whilst playing with Nagios Core over the past couple of weeks again I got annoyed with it returning to the main page every time I refreshed it.
A quick google turned up a few articles and I found that it’s an easy change to the index.php file. Now my Nagios servers default to the Host Groups page which is much more useful !
Nagios – Configuring Global Event Commands Using send_nrdp.py
Nagios – Configuring Global Event Commands Using send_nrdp.py
Today I finally worked out how to configure the send_nrdp.py script as a Global Event Command after scouring the web for the solution. As with most things Nagios related, the documentation out there is a little light so I thought I’d put this up in case it helps others.

Nagios Pi Part Three
Nagios Pi Part Three
Since my last post I’ve been mostly looking at how to start and shut down my environment at a certain times with success in starting but failure in shutting down.
The starting of my environment was an easy enough task with a simple bash script to send WOL packets to my hosts and using a For loop to fire it off five times for good measure.
