TinyCore Linux: Build a ‘Persistent’ Web Server
KB ID 0001697 Problem Recently I was building a lab for testing load balancing, and needed some web servers, I could have built three Windows servers, but I wanted to run them in EVE-NG, so they had to be as light as I could make them. I chose TinyCore Linux, (I know there are smaller options, but it’s light enough for me to run, and work with). The problem occurs when you reboot the TinyCore host, it (by default) reverts back...
EVE-NG: Committing / Saving Qemu Virtual Machine Settings
KB ID 0001695 Problem I’ve been working on a load balancing lab in EVE-NG this last week or so. I created some web servers (in TinyCore Linux,) to act as the web servers in that lab. (Essentially they serve a different colour web page so I can test the load balancing is working OK). Now I wanted to save the changes I made so that I could redeploy the configured servers to multiple labs. But when you deploy a qemu VM as a node in...
NGINX Error: ’98: Address already in use’
KB ID 0001694 Problem After an update, (WordPress – unrelated) yesterday, this website fell over! I rebooted the host, site was still down. I reluctantly restored to the previous evenings backup, and powered on the server. Alarmingly the site was still down! I logged a call to my VPS provider, and attempted to troubleshoot the problem while I was waiting. Very soon it was apparent my server appeared to be OK, but my web hosting...
Azure: Point to Site VPN From mac OS?
KB ID 0001693 Problem We mac users always get overlooked. If I had a pound for every time I’ve heard ‘Yeah we don’t support macs?” I would be a rich man. But thankfully this makes us work things out for ourselves usually! So recently I did a article Azure: Point To Site VPN (Remote Access User VPN) but what if you want to use the same solution for a remote mac user? Solution Firstly you will want to download...
Azure VPN: Point To Site VPN (Remote Access)
KB ID 0001692 Problem Given my background I’m usually more comfortable connecting to Azure with a Route Based VPN from a hardware device, like a Cisco ASA. I got an email this afternoon, a client had a server in a private cloud and a server in Azure, they needed to transfer files from the Azure server to the server in the private cloud. Now on further investigation this client had a Cisco vASA so a VPN was the best option for...
Veeam: Backup to Public Cloud?
KB ID 0001691 Problem I’ve always been a fan of Veeam, I’ve championed it for years, as a consultant and engineer I want solutions that are easy to deploy, administer, and upgrade, that cause no problems. Like all things that are easy to use, and gain a lot of popularity, Veeam is starting to get DESTROYED BY DEVELOPMENT. What do I mean? Well, things that were simple and easy to find now require you to look at knowledge...

AnyConnect: Allow ‘Local’ LAN Access
KB ID 0001689 Problem Note: This WONT WORK if you ‘force-tunnel’ or ‘tunnel-all’ remote VPN traffic, (if you are unsure Google ‘what’s my ip’ > Take note of it > Connect to AnyConnect and repeat the procedure, if your public IP address has changed to the IP address of the ASA then you force-tunnel/tunnel-all traffic). With more people remote working now, I’m getting a lot more...
VMware Converter ‘A file I/O Error Occurred’
KB ID 0001688 Problem It seems every time I use VMware Converter, there’s some new error that jumps up and makes me stumble! Yesterday the problem was; FAILED: A file I/O error occurred while accessing Solution Some searching told me this is actually a DNS problem, (where the converter could not resolve the DNS name of the machine being converted). BUT I had put the FQDN directly into this machines ‘hosts file’ so I...
