Hi chaps

Just found your podcast, I started on #49, but I was yelling at my player when you were talking about crafting the router scripts.

What you need is a macro processor, have a look at pyexpander, though there are lots of others. The simpler way would be to put some unique strings into the document like $IP-ADDRESS$ and then do a global replace on these strings. Sort of manual macro processor.

Keep up the good work on the podcast


Admin Admin Podcast #051 Shownotes – Basics of OpenStack

Al had issue with his VPS and had to restore one of his Database, Cert bot  to create and renew certs for Let’s Encrypt certificates.

Andy also had issues with wordpress

Jerry has issue with large log files filling up his hosted server.

Common OpenStack Deployments – The book al was talking about

High Availability for Pets and Hypervisors – State of The Nation – Good youtube video explain issue with HA in OpenStack this.


Handle the identity between services. Provide authentication and access management to OpenStack.


Provides a web interface and api to manage OpenStack instances.


Provide the compute (ie hypervisor) to run the instances. This run KVM. There is scheduler and conductor to automate the created and delete of instances.


Send messages between the services using Advanced Message Queuing Protocol (AMQP). I.E a user requests a new instance in Horizon. Message is sent via rabbitMQ to NOVA-conductor where an instance is created via NOVA-scheduler and then a message is then set back to Horizon once the instance has been created


Handles the networking stack, provides networks encapsulation (VXLAN),Firewalling Loadblancing and Floating IPs.


Hold images to provide to instance to transfer them to a nova services.


Provide charageback and telemetry of the resources used in OpenStack


Provides block storage to instances. Cinder can present mountable volumes to instances


Object Storage which developer can use API to access high available storage.


Bare metal provisioning of physical hardware to provide provisioning of nova hosts using IPMI (IE ILO) also can be used to power and shutdown physical hardware depending on hardware load.


To provide support of containers in OpenStack.

Admin Admin Podcast #050 – Show Notes – Retro Computers

Do you have a plan what to do when your network gets hit by a CryptoLocker? Because it is a matter of “if” not “when”, best is to be prepared. Of course, most of you will have Veeam backups – however, before you restore those, you need to find and kill the source of malware, right? And not everyone know how to proceed here. Usually, it is dead simple: just open properties of the decryption instructions file that gets created by ransomware, and see who is the file owner – this will usually point to the infected user/machine. If that does not help because the owner is a group (or ransomware is super smart), go to Computer Management snap-in on the file server with files being encrypted, and open Shares > Open Files. One of the users will have hundreds of open files, this would be it. Now, just disable that user and their computer account until the issue is resolved, and perform the restore from the latest Veeam backup!

Why would you?


  • As a contractor, you work for your own company who supplies services to the company you’re working for. They don’t have to pay for holidays/national insurance/pension, etc.
  • They take no risk – you often have to take out insurance as a contractor


  • The money is much better
  • “Tax efficiency”. Pay yourself a nominal salary that keeps you under the PAYE threshold
  • Pay yourself dividends, which are only subject to corporation tax
  • Pay VAT as a lump sum to HMRC on profits only – can claim it back on any business expenses
  • Business expenses also eat into profits, but lower profits mean a lower overall tax bill


Are you aware of Hacktoberfest? Contribute 4 Pull Requests to any github project (including documentation, unit tests or even *shock horror* code…) and get a T-Shirt and stickers.

It’s a great idea for getting people dipping their toes into using git, and potentially into contributing to open source projects.

I “won” it last year (as in, I completed my four PRs and got the T-Shirt and stickers), and I’m entered again for this year.

All the best,

Jon “The Nice Guy”
