non routable IP address
Online IP Subnet calculator
Bit Cricket Subnet Software
The Example Al was Giving:
172.30.4.0 / 22 (255.255.252.0) – The Current subnet the site was Using it could have upto 1022 Host.
172.30.4.1 – 172.30.7.254 – Usable IP address Range
172.30.4.1 -172.30.4.254 – Devices with static IP address
172.30.5.1 – 172.30.6.254 – DHCP Range – Clients
172.30.6.1 – 172.30.7.254 – spare
We Divided the subnet into the following smaller subnets
172.30.4.0 /24 -254 address for server
172.30.5.0 /24 – PCI -254 address forr PCI Server
172.30.6.0 /23 – DHCP – 510 address for Clients

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
Stuart
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.
Keystone
Handle the identity between services. Provide authentication and access management to OpenStack.
Horizon
Provides a web interface and api to manage OpenStack instances.
Nova
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.
RabbitMQ
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
Neutron
Handles the networking stack, provides networks encapsulation (VXLAN),Firewalling Loadblancing and Floating IPs.
Glance
Hold images to provide to instance to transfer them to a nova services.
Ceiometer
Provide charageback and telemetry of the resources used in OpenStack
Cinder
Provides block storage to instances. Cinder can present mountable volumes to instances
Swift
Object Storage which developer can use API to access high available storage.
Ironic
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.
Magnum
To provide support of containers in OpenStack.

THE WORD FROM GOSTEV:
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!

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,
