Automating RHEL Administration with Ansible

Introduction

Red Hat Enterprise Linux (RHEL) is a popular choice for enterprise environments due to its stability, security, and robust support. Managing RHEL systems can be complex, especially when dealing with large-scale deployments. Ansible, an open-source automation tool, can simplify this process by allowing administrators to automate repetitive tasks, ensure consistency, and improve efficiency.

Benefits of Using Ansible for RHEL System Administration

Consistency: Ansible ensures that configurations are applied uniformly across all systems.

Efficiency: Automating tasks reduces manual effort and minimizes the risk of human error.

Scalability: Ansible can manage hundreds or thousands of systems from a single control node.

Idempotency: Ansible playbooks ensure that the desired state is achieved without unintended side effects.

Writing Playbooks for Common RHEL Configurations

Ansible playbooks are YAML files that define a series of tasks to be executed on remote systems. Here are some common RHEL configurations that can be automated using Ansible:

Homelab Changes

Okay, so Portainer stacks are where its at. I now have fully redudent time servers.

Is it unecessary–yes, but redundent time servers in Docker is kinda neat.

At somepoint I will have to pickup some proper NTP hardware and run my own fully operated time server. The clocks and GPS stuff seems cool.

I just can't bring myself to spend that money right now. It is shockingly pricey and I don't know that it is that interesting yet. We will see what happens.

Aruba CX Switch Setup Commands

In Jan 23, I purchased 12x Aruba 6200F to replace ageing HPE ProCurve switches, which had the following challenges (to name a few):

Only supported 100mbps (yes, even on the uplink side)

Had ports that were starting to fail

Did not have a recent feature-set, meaning some newer options etc. were unavailable

Were that old that configuring them: - With SSH required negotiation attempts using a specific, older and insecure cipher - Through the WebGUI required IE (for either Flash or ActiveX reasons)

Were no longer supported by any warranties etc.

While I cannot post the As-Built, I can post the commands that I used to set up these devices. These Aruba CX switches use a vastly different (and after using it, improved) CLI compared to the ProCurve CLI. I do still lament the loss of the "menu" command.

Disable VSF (if not using stacked switches):

If any changes have been made, take a backup of the config. This process will wipe the config (and I learned the hard way!)

Enter configure mode

Remove “members” (there should be none): no vsf member 2-8

Remove the conductor: no vsf member 1

You’ll be prompted whether you’re sure about making this change. 

“Unconfiguring the primary switch of the stack without a standby will make the stack unusable.  Do you want to continue (y/n)?”

Type “Y”

The switch will reboot with no config.

Set the clock:

Enter configure mode

Set the time zone: clock timezone australia/sydney

Set the NTP server: ntp server pool.ntp.org iburst version 4

Enable ntp: ntp enable

Set the MOTD Banner:

Enter configure mode

Type the command with the escape character: banner motd ^

Type your banner as needed. Ensure the escape character is at the end of the banner prompt.

SNMP Config:

Enter configure mode

Enable SNMP traffic to pass: snmp-server vrf default

Set contact: snmp-server system-contact user@place.com (Replace user@place.com with the contact details of the administrator)

Set community: snmp-server community xx (Where xx is the SNMP Community. Do not use public!)

Set location: snmp-server system-location xyz

Use template: BD-X-Y01 [-33.85695,151.2152]

Note: The template is this way due to being used with LibreNMS.

VLANs:

To create a VLAN:

Enter configure mode

Create the vlan (this example creates vlan 20): vlan 20

Name the vlan (this example names the vlan “test”): name test

To configure a port or ports with multiple VLANs:

Enter configure mode

Choose the interface/s: interface 1/1/1 OR interfaces 1/1/1-1/1/24 (this will configure ports 1-24)

Set the untagged vlan: vlan trunk native 194

Set the vlans that are allowed to run on the port: vlan trunk allow 60,194

To configure a port with a single vlan:

Enter configure mode

Choose the interface interface 1/1/48

Set the vlan vlan access 1

To configure a LAG:

Enter configure mode

Create the LAG: interface lag xx (Where xx is the LAG ID)

Set the LAG to enable LACP: lacp mode active 

Assign a native VLAN: vlan trunk native x (Where x is the native VLAN)

Assign allowed vlans: vlan trunk allow x,y,z, (Where X,Y,Z represent the VLANS that you wish to have access over the LAG)

Configure

Select the interfaces you wish to add to the LAG: interface 1/1/47-1/1/48

Add the interfaces to the LAG: lag x (Where x is the LAG ID used in step 2)

Configure the in-band management IP:

Enter configure mode

Select the vlan you wish to set the management IP on: interface vlan 999

Set the vlan not to use DHCP: no ip dhcp

Set the IP Address: ip address xx.xx.xx.xx/yy

Set the vlan to come up: no shutdown

Set the default gateway:

Enter configure mode

Set the Default Gateway: ip route 0.0.0.0/0 x.x.x.x (replace x.x.x.x with your default gateway)

 

DHCP Snooping:

Enabling this means that DHCP traffic coming into a "snooped" port will be blocked, except for traffic entering into “snooped & trusted” ports.

Enter configure mode

Enable DHCPv4 Snoop: dhcpv4-snooping

Select interfaces where you wish DHCPv4 traffic to pass: interface 1/1/48,1/1/52

Trust these interfaces: dhcpv4-snooping trust

Enable DHCPv6 snoop: dhcpv6-snooping

Loop prevention:

Enter configure mode

Select the interfaces: Interface 1/1/1-1/1/48

Enable loop protect: loop-protect

Set the action of Loop protect: loop-protect action tx-disable

Set how long in seconds after disabling the port that it should come back up: loop-protect re-enable-timer 60

Fault Monitor:

Enter configure mode

Create a Fault Monitor profile named all: Fault-monitor profile all

Monitor all faults available from the Fault Monitor: All

Choose the interfaces you wish to monitor faults on: Interface 1/1/1-1/1/48

Apply the fault monitor profile: apply fault-monitor profile all

Disable L3 Switching (IF REQUIRED):

Enter configure mode

Select the interfaces that don’t require L3 switching: interface 1/1/x

Why the Demand for Wi-Fi Clocks is Increasing in Every Industry?

Undoubtedly, clocks are a very important component of everyone’s daily life.  With the help of timepieces, every person is able to do their work on time. There is no more reliable source for time management other than the wall clocks. However, due to advanced technologies and new inventions, many types of timepieces are available in the market.

 A person can find many different varieties of timers. One such popular variety of timepieces is Wi-Fi clocks. Hence, it is also the topic of today’s article. Let’s discuss about them.

How Wi-Fi Clocks are Different from Analog Clocks?

These timepieces are also known as synchronized clocks.  The wifi wall clock is similar to that of the other devices on a Wi-Fi network.  They talk to the network to pull the correct information about the precise time. These timepieces are very different from analog ones as their system combines wireless simplicity with total control.

Unlike the normal wall-timers, There is no need to run wires between these clocks as they receive the time data from the internet by using wi-fi or an in-house NTP server. These timepieces are very simple to connect to the network and set them to work. In addition to that, their installation and maintenance are very easy and less expensive.

Which Are the Industries that Uses Synchronized Timepieces?

The question to ask should be which are the industries where synchronized clocks cannot be found. Almost every business is using these automated timepieces for better and error-free time display. Here are some of the common industries that use the automated timepieces:

Manufacturing Industry- In these sectors, the wi-fi clock systems are used to ensure the smooth running of the production line. They help increase the overall efficiency of the company by reducing the downtime. Moreover, accurate timekeeping is essential for the coordination of logistics, maintenance of inventory, and compliance with regulatory requirements.

Education Sector- The synchronized timepieces create an environment of cohesive learning by making sure that the exams are starting and ending on time. Correct time tracking is essential to maintain a structured schedule that improves the overall experience of learning for students and the staff.

Transportation Industry- Precise timekeeping is very important for coordination of the schedules and to ensure smooth and on-time functioning of airports, train stations, and other types of transit hubs. The wifi clock helps prevent any kind of delays, maintaining safety standards, and providing accurate timings of arrival and departure to the passengers.

Government or Public Sector-  The automated timepieces for the wall assist government agencies and public utilities in responding quickly and efficiently to an incident or emergency. A correct time recording is very beneficial in maintaining the trust and confidence of the public in these crucial services.

Hence, there is a great demand for synchronization timepieces in the above-mentioned industries.  Anyone who wants an efficient and advanced system for accurate timekeeping must opt for the Wi-Fi clocks.
