What is Latency?
What is Latency? KB ID 0001874 What is Latency? I hear people use the word ‘Latency’ a lot, mostly without ever really understanding what it is, unlike its close relations bandwidth and thoughput* which are measurments of data, latency is a measurment of TIME, and in a lot scenarios is variable depending on what’s happening. *Note: Too low bandwidth and thoughput can increase latency. There will always be latency,...
Proxmox Update Package Database Error
Update Package Database KB ID 0001873 Problem More of an annoyance than a problem to be honest, but every 24 hours I get the following errors logged against every host in my Proxmox cluster. Description ‘Update Package Database’ If you drill down into that error, you will see. TASK ERROR: command ‘apt-get update’ failed: exit code 100 Solution : Update Package Database This happens because (by default) the...
Proxmox HA Cluster
Proxmox HA Cluster KB ID 0001872 Problem Proxmox HA Cluster: As the name implies this allows the cluster to ‘restart’ failed virtual machines on another host in the cluster in the event of a host failure. Unlike VMware (that has a vCenter appliance to do this) in Proxmox it can be configured from any host. Which may seem like an advantage – but the GUI can get a little ‘clunky’ whilst configuring HA....

Proxmox You Do Not Have a Valid Subscription
You Do Not Have a Valid Subscription KB ID 0001870 Problem I’m only just getting comfortable with Proxmox, whilst building a three node cluster recently I was pestered with this ‘nag’ dialog.

Windows Create NFS Share
Windows Create NFS Share KB ID 0001869 Problem It has been a while since I mentioned this, but if you have a Windows server, and you would like to present an NFS Share, the process is pretty straight forward. The following procedure was carried out on Windows Server 2022, but the process is pretty much the same going all the way back to Server 2012. Solution : Windows Create NFS Share Install Server for NFS (GUI) You need to add the...
Proxmox on VMware
Proxmox on VMware KB ID 0001867 Problem In the wake of Broadcom doing its best to strangle VMware and its discontinuation of free ESX. I thought I’d look at the free alternatives. Previously I looked at Nutanix (and was not over enamoured.) So the next option is Proxmox. Proxmox Virtual Environment (Proxmox VE) is a robust open-source server virtualisation platform that merges two cutting-edge virtualisation technologies Linux...
Nutanix on VMware vSphere ESX 8
Nutanix on VMware KB ID 0001866 Problem In the wake of Broadcom doing its best to strangle VMware and its discontinuation of free ESX. I thought I’d look at the free alternatives. The most obvious is Nutanix CE (Community Edition) which is both free, and lets you have up to 4 nodes – which is impressive, as Free ESX does not have clustering or access to vCenter. Honest Opinion: It’s very flaky, if you want a solution...
Nutanix: Could Not Reach Next Server
Could Not Reach Next Server KB ID 0001865 Problem Nutanix is very flaky! On a new (single host cluster,) post setup whilst attempting to login to Prism for the first time, it wanted to link to my Nutanix account. Unknown host, could not reach NEXT server. Please configure name server Solution : Could Not Reach Next Server Why do I say it’s flaky, well I defined a DNS server when I created the cluster. However, If I fired up SSH...
Camtasia Recording Quit Unexpectedly
Recording Quit Unexpectedly KB ID 0001864 Problem I use Camtasia every so often, both for sending screencasts to colleagues, and for making videos for my YouTube channel.

Recording Quit Unexpectedly Camtasia is unable to recover the recording. Solution: Recording Quit...
