Hospitable IT

I ran into a weird problem a few nights ago during a change with DNS caching on a VMWare vCSA that took a while to resolve so I thought it was worth posting about.

This little script kinda goes with the Backup script in my previous post. The specific use case is that of an ESXi host that has had to be rebuilt from scratch

I have been doing a bit of work with ESXi recently and came up with this little PowerShell script to quickly back up the configurations of all the ESXi hosts managed by a particular vCenter Server.

This weekend I have been messing about with automating the installation and configuration of ESXi for an upcoming project. I got stuck on a particular aspect of this so through it was worth posting about.

I was using Remmina on a Raspberry Pi as an RDP client to access a Windows RDS Server and display status screens from various monitoring applications. I already had Remmina configured to auto start, I just needed to delay it by about 60 seconds.

I have recently had the opportunity to get my hands on a shiny new Cisco DNA Center appliance and some sexy new Catalyst 9K switches. One of the first items on my to-do list was to configure an existing ISE server as an external authentication source using TACACS.

This is a quick post on how I handled the Captive Network Assistant for a site that was hosting a walled garden WiFi network and wished to redirect clients to a media service portal splash page.

Today I got stuck for while when upgrading an on premise installation of the Azure Multi-Factor Authentication Server from 7.3 to the latest version 8.0.1.1 so I though it was worth posting about.

A site I work with uses the Cisco Voice/Collaboration platform and doesn’t have a good mechanism for monitoring it. They use PRTG so this was a great opportunity for me to build upon my rather basic PowerShell scripting skills and create a useful PRTG sensor.

I was having a lot of problems today moving the SFTP backup target for a Cisco Unified CCX system. To cut a long story short (and it took a bloody long time to work this out!), the problem was with the ciphers that were being made available by the SSHD service on the new backup target.
