Exchange – Move ‘ALL’ Mailboxes From One Database to Another
KB ID 0000864 Problem While replacing an Exchange Server on my test network last week, I needed to get all the mailboxes moved across to the new one. Exchange gets upset if you try and delete a mailbox database that has data in it. Solution 1. Launch the Exchange Management Shell > Firstly lets get the names of my Databases, then I can simply copy and paste them into the move mailbox command. Get-MailboxDatabase Get-Mailbox...
AnyConnect: ‘Quick and Dirty’ Duo 2FA
KB ID 0001701 Problem Normally if I were deploying Duo 2FA with AnyConnect I’d deploy a Cisco RADIUS VPN on my LAN, (usually on my Duo Authentication Proxy). See the following article; AnyConnect: Enable Duo 2Factor Authentication However, last time I set this up, a colleague said ‘Oh by the way, you don’t need to do that, you can just point the firewall directly at Duo’. I was initially skeptical but I tried...
F5: Static Load Balancing (Ratios)
KB ID 0001700 Problem In the previous post, we deployed a web load balanced solution with three web servers. Out of the box the BIG-IP solution will use Round Robin load balancing and it will treat all Nodes or Pool Members the same, (it assigns a RATIO OF 1). Everything gets weighted the same, and the F5 will send requests to the Nodes or Pool members one at a time. But what if one of those web servers was a beast of a machine, with...
AnyConnect: Unauthorized Connection Mechanism
KB ID 0001699 Problem I was assisting a colleague to setup some AnyConnect for a client this afternoon, when all of a sudden I was met with this; VPN Logon denied, unauthorised connection mechanism, contact your administrator Solution This was a confusing one, I replicated the problem on my own test firewall. All I had done was change the AAA method from LOCAL to LDAP? It took me a while to figure out what was going on? The reason why...
F5: Setup Basic Web Load Balancing
KB ID 0001698 Problem In past articles I’ve got my F5 BIG IP appliance up and running, and I’ve built some web servers to test load balancing. Now to actually connect things together and start testing things. Below is my lab setup, I will be deploying simple web load balancing (Static: Round Robin) between three web servers, each serving a simple HTTP web site. Test F5 to Web Server Connectivity For obvious reasons the F5...
EVE-NG Deploying F5 BIG-IP
KB ID 0001696 Problem I already had some F5 Images in my EVE-NG, but I wanted to run version 16.x. However, I didn’t think that was officially supported, so I thought I would try and get it running anyway! Solution Theres no need to scour the internet for ‘dodgy’ versions, F5 will quite happily give you the latest version, just sign up for a free account, and you can download the image. While you are there, you can...
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...
