RSA SecurID Error – ‘106: The Web server is busy. Please try again later’
RSA SecurID Error KB ID 0000975 Problem Not the most descriptive of errors! In fact this has got nothing to do with the busyness of the web server at all. Solution : RSA SecurID Error What’s actually happening is the RSA agent on this machine (in this case a web server) cannot communicate with the RSA Authentication Manager. In my case the web server was in a DMZ, and the RSA Authentication Manager Appliance was in another DMZ....
Fortigate Hairpin NAT
KB ID 0001781 Problem Imagine the following scenario, you have a PUBLIC web server and it’s either in the same network your uses are or attached to a DMZ on your FortiGate.

I’m setting this up in EVE-NG on the work bench...
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...
Certificate Chain Incomplete
KB ID 0001570 Problem The certificate here at PNL expired over the weekend, I got a new one and installed it. All appeared to be fine until I did an online check to make sure it was OK. The server’s certificate chain is incomplete Solution I had this problem once before, back then I was using Apache and CentOS7, and things were a little different, (now I’m using NGINX and Ubuntu 18.04). Essentially you see this error...
