VyOS Increase Disk Space

0

In this blog post, I will walk you through the process of increasing disk space on a VyOS installation. Whether you’re running VyOS on a virtual machine or a physical server, this step-by-step guide will help you seamlessly allocate more storage to keep your network operations running smoothly. From resizing partitions to adjusting file systems, we’ll cover everything you need to know to efficiently manage your VyOS environment’s disk space.

Preparation

Before you begin, ensure that you have a configuration backup of your VyOS system. This precautionary step is essential to safeguard your current settings and configurations, allowing for a quick recovery in case any issues arise during the disk space expansion process. Proper backups are crucial for maintaining the integrity and continuity of your network operations.

VyOS Commands

Here is an overview of the commands I used on the VyOS virtual machine to make it workout:

  1. Shutdown the virtual machine
  2. Increase the disk space of the boot media
  3. Start the virtual machine
  4. Run the following commands:
# Validate size
fdisk -l
df –h

# Remove partition
fdisk /dev/sda
p (print partition)
d (delete partition)
p (print partition)

# Create new partion
• n (create a new partition)
• p (select primary)
• 1 (select 1 since this only partition)
• 2 (this first cylinder saw in b) )
• 12191 (last cylinder - 1 )
• w (press w for writing change)

# Check
sudo partprobe

# Reboot system
reboot

# Confirm that partition size
partx /dev/sda

# Tell the Linux Kernel about the Change in disk size
sudo resize2fs /dev/sda1

# Reconfirm the increase disk size
df -h

# Reboot system to verify
reboot

Wrap-up

So this is my blog post about increasing disk space on a VyOS virtual machine. Hope it was useful for someone! Please respond below if you have any comments or additional information!

VMware vExpert 2024 Award

0

Hey everyone, let me share some awesome news, I’ve just been awarded the VMware vExpert 2024 for the eighth year in a row! 🏆🎉

Now, if you’re scratching your head wondering what exactly that means, don’t worry, I’ve got you covered. Essentially, the VMware vExpert program is like the club for folks who are really into VMware technologies. And guess what? I’m super honored to be part of that club, especially for the eighth time running!

First things first, I gotta give a massive shoutout to VMware / Broadcom and the amazing vExpert Team. Seriously, these folks are like the unsung heroes behind the scenes, making sure the VMware community stays vibrant and buzzing with excitement. Without their hard work and dedication, none of this would be possible.

I’ve met some incredible folks along the way, fellow vExperts who have become friends, mentors, and colleagues at ITQ, and most importantly, we’ve learned from each other.

So, what does eight years of vExpert status mean to me? Well, for starters, it’s a reminder to never stop pushing myself, to keep learning, growing, and evolving as a technologist. Whether I’m writing blog posts, giving talks at conferences, or just hanging out in the VMware community Slack channel, I’m always looking for ways to give back and pay it forward.

And of course, none of this would be possible without the support of my family, friends, and colleagues. You guys are the real MVPs, always cheering me on, even when I’m knee-deep in a particularly gnarly ESXi upgrade.

So here’s to another year of virtualization adventures, of pushing the boundaries of what’s possible with VMware technologies, and most importantly, of being part of an incredible community that I’m proud to call home.

Thanks again to VMware and the vExpert Team for this amazing honor. Let’s make the next eight years even more epic!

See you next time! 🙂 Thanks for reading my blog.

Aria Orchestrator – Add CD-ROM to a Virtual Machine

0

In this blog post, we will add a CD-ROM device to a vSphere Virtual Machine in an automated way. This will be done with vRO (vRealize Orchestrator/Aria Automation Orchestrator). The action is used for creating a CD-ROM drive when provisioning a new machine with vRO.

I am doing this blog post because, after a lot of Googling, I could not find a good example or solution online. So it was time to do a blog post after figuring out what I needed to do!

So let’s start the blog post about adding a CD-ROM to a virtual machine.

vRO – Action Code

Here is the vRealize Orchestrator/Aria Automation Orchestrator code for an action. This action creates the specification for adding a CD-ROM to an already running or a new virtual machine. It’s a lot of code for a “simple” CD-ROM drive because, in the vCenter Server interface, it feels like a couple of easy clicks. In the backend it is another story, see the code below. You need to attach a lot of specifications together to add a CD-ROM to a virtual machine.

Action details:

  • Name: createCdDvdDriveSpecification
  • Version: 1.0.0
  • Description: Create the specification for a vSphere CD/DVD drive to add a CD/DVD drive to a virtual machine with the VMware vCenter SDK.
  • Inputs: None
  • Return Type: Any
  • Location: com.bv.vsphere.vm.spec
// Set variable
var deviceConfigSpecs = new Array();
var deviceConfigSpec;

// Add CD-ROM connect spec
var connectInfo = new VcVirtualDeviceConnectInfo();
    connectInfo.allowGuestControl = true;
    connectInfo.connected = false;
    connectInfo.startConnected = true;

// Add CD-ROM backing spec
var backingInfo = null;
    backingInfo = new VcVirtualCdromRemotePassthroughBackingInfo();
    backingInfo.deviceName = "";

// Add Virtual CD-ROM
var cdrom = new VcVirtualCdrom();
    cdrom.backing = backingInfo;
    cdrom.controllerKey = 200;
    cdrom.key = 0;
    cdrom.unitNumber = 0;
    cdrom.connectable = connectInfo;

// Create CD-ROM configuration spec
var deviceConfigSpec = new VcVirtualDeviceConfigSpec();
    deviceConfigSpec.device = cdrom;
    deviceConfigSpec.operation = VcVirtualDeviceConfigSpecOperation.add;
    deviceConfigSpecs[0] = deviceConfigSpec;

// Troubleshooting generated configuration specification
// System.debug(deviceConfigSpec);

// Return specification
return deviceConfigSpec;

vRO – Workflow

This is a part of a larger workflow but it will help you get started. I have listed the most important parts of creating a virtual machine and how to get started. This code is quite identical to changing a virtual machine to add a CD-ROM drive.

// Load module
var vsphereVmSpec = System.getModule("com.bv.vsphere.vm.spec");

// Set variable
var actionName = arguments.callee.name.substr(6);
var deviceConfigSpecs = [];
var deviceConfigSpec;

// Virtual machine spec
var vmConfigSpec = new VcVirtualMachineConfigSpec();
// Lot more stuff here like VM name, resource pool, host etc

// Add CD-ROM
deviceConfigSpec = vsphereVmSpec.createCdDvdDriveSpecification();
deviceConfigSpecs[ii++] = deviceConfigSpec;

// Combine configuration
vmConfigSpec.deviceChange = deviceConfigSpecs;

// Start Virtual Machine creation
try {
    System.log("[" + actionName + "] Starting Virtual Machine creation (" + virtualMachineName +")");
    task = vmFolder.createVM_Task(vmConfigSpec, vmResourcePool, vmHost);
}
catch (exception) {
    throw "[" + actionName + "] exception";
}

// Return VC:Task
return task;

Wrap-up

So this is my technical blog post about adding a CD-ROM to a virtual machine with vRealize Orchestrator (vRO). Hopefully, it is useful for somebody, please respond below if you have any comments or additional information! See you next time! 🙂

OpenSSL Creating Wildcard Certificate Request

0
OpenSSL Wildcard Certificate Request

In this short blog post, we will create an OpenSSL request for a wildcard certificate. We are going over the installation, configuration, and request. I am performing the steps on a Windows 11-based machine and requesting the certificate at https://www.xolphin.nl/ an external certificate provider, this can also be an internal certificate provider like Microsoft Active Directory Certificate Services (ADCS).

Leveraging a wildcard certificate can be used for many purposes. This can be an internal or external certificate. On a load balancer or a web server with multiple https services. In my case, I am using it for my Lab environment with a load balancer. I am trying to eliminate the certificate complexity for some simple testing of web applications in Kubernetes.

Environment

My environment for performing this operation is as followed:

  • Operating System: Windows 11 X64
  • Public internet access: yes
  • Permissions on the system: Administrator

Installation of OpenSSL on Windows 11

To install OpenSSL on a Windows 11 machine the easiest way is with the package manager “Choco“. Open a PowerShell command prompt with administrative permissions and run the following command:

Configuration OpenSSL on Windows 11

To create a certificate you need to tell OpenSSL what to generate. So we create a configuration file for OpenSSL that specifies what type of certificate should be generated.

Create the following configuration file called “config.cfg“. This is the configuration file that will be used by OpenSSL when running the command listed below. Make sure you change your domain name and information in the configuration file.

[ req ]
default_bits            = %In most cased: 2048 or 4094%
default_keyfile         = %key file name%
default_md              = sha512
distinguished_name      = req_distinguished_name
encrypt_key             = no
prompt                  = no

[ req_distinguished_name ]
commonName              = %Certificate address > your wildcard%
countryName             = %Company country code%
emailAddress            = %Administrator/IT email%
localityName            = %Company location%
organizationName        = %Company name%
organizationalUnitName  = %Company department%
stateOrProvinceName     = %Company location province%
[ req ]
default_bits            = 4096
default_keyfile         = wildcard.domain.com.key
default_md              = sha512
distinguished_name      = req_distinguished_name
encrypt_key             = no
prompt                  = no

[ req_distinguished_name ]
commonName              = *.domain.com
countryName             = NL
emailAddress            = admin@domain.com
localityName            = Amsterdam
organizationName        = Domain B.V.
organizationalUnitName  = IT
stateOrProvinceName     = Noord-Holland

OpenSSL Creating Wildcard Certificate Request

Now it is time for generating the certificate request that can be delivered to your certificate provider. This can be done by running the following command in an elevated PowerShell command-prompt.

# Set the path variable
$path = "c:\Users\$Env:UserName\Desktop\cert"

# Create directory
mkdir $path

# Copy the config.cfg into the $path location (manually)

# Create the certificate request
openssl req -new -nodes -out "$path\wildcard.domain.com.csr" -config "$path\config.cfg" -keyout "$path\wildcard.domain.com.key"

# After running the commands, you will end up with three files in the $path location
- config.cfg
- wildcard.domain.com.csr
- wildcard.domain.com.key

Signing the request

Go to your certificate provider website and upload the “wildcard.domain.com.csr” file. You should receive the wildcard certificate in a couple of minutes/hours depending on the certificate provider.

Wrap up

So this is my blog post about creating a wildcard certificate with OpenSSL. Hopefully, it is useful for somebody, please respond below if you have any comments or additional information! See you next time! 🙂

Ubiquiti UniFi Inform/Adopt Access Point

0

Today we will look at the Ubiquiti UniFi inform/adopt access point process. Recently I bought some new UniFi equipment for my home environment but I had some issues with assigning them to a new UniFi Controller. Also, I received a secondhand unit that was already configured to an existing UniFi Controller. Because it took me some time to figure out the complete process and some items were not directly clear to me it was time for a quick write-up.

This blog post will cover three scenarios depending on the status of your UniFi access point.

Some important notes:

  • In case your UniFi Access Point management network is not in the same network as the UniFi Controller it will not be found automatically by the UniFi Controller.
  • The network configuration is a little bit more complex than the standard for home environments:
    • Dedicated management network for the management interface of the UniFi APs.
    • Two separate SSIDs with two separate networks.

Environment:

I created an example configuration for this blog post based on my home environment. Below is also a basic network diagram to give you some insight into the configuration.

Network configuration:

  • UniFi Controller IP address: 192.168.10.1/24 (VLAN 10)
  • UniFi Access Point Management IP address: 192.168.11.1/24 (VLAN 11)
  • Two separate WIFI SSIDs backed by different networks for isolation of devices:
    • SSID: Guest-Wifi / VLAN 12 / 192.168.12.X/24
    • SSID: Home-Wifi / VLAN 13 / 192.168.13.X/24

Device types:

  • UniFi Controller: version 7.3 (docker image) running on a Synology NAS.
  • UniFi Access Point: Ubiquiti UniFi 6 Pro

Components explained:

  • UniFi Controller: The UniFi Controller is the management suite/management interface for controlling the UniFi environment. This is a free downloadable software package from the Ubiquiti website or you can pay for the cloud service.
  • UniFi Access Point: The access point is the physical component you buy from Ubiquiti which after a successful configuration a WIFI client connects to.

Diagrams/photos:

Here is a basic network diagram of the UniFi setup of the environment and also some basic screenshots to give you an idea.

Credentials

Default credentials with a new or reset UniFi access point.

  • Username: ubnt
  • Password: ubnt

Procedure: New UniFi Access Point

This is the procedure for a brand new access point or an access point that had a factory reset. With this command, you will let the UniFi Controller know the UniFi access point is available for adoption.

  1. Power up the access point
  2. Check the DHCP server for its lease
  3. Connect with SSH (for example use Putty)
  4. Login with the following default credentials:
    • Username: ubnt
    • Password: ubnt
  5. Run the following command on the UniFi Access Point:
# Syntax
set-inform http://%UniFi-Controller-IP-Address%:8080/inform

# Command with an example IP address to let the UniFi Controller know the AP is ready for adoption
set-inform http://192.168.10.1:8080/inform

Procedure: Physical Device Reset

This is the procedure for when the device is unreachable or the login credentials are unknown:

  1. Locate the access point, and remove it from its bracket (it might differ per type of UniFi access point).
  2. Make sure the access point has power and is booted before starting the procedure.
  3. Hold the reset button on the underside with a paperclip for 10 seconds (it might differ per type of UniFi access point).
  4. Continue with the procedure “New UniFi Access Point”.

Procedure: Software Reset

This is the procedure for when the device is accessible but needs to be moved to another UniFi Controller instance.

  1. Power up the access point
  2. Check the DHCP server for lease
  3. Connect with SSH (for example use Putty)
  4. Log in with the known configured credentials by the current UniFi Controller.
  5. Run the following commands on the UniFi Access Point:
# Run the following command to issue a factory reset on the device
set-default
or
syswrapper.sh restore-default

# Syntax
set-inform http://%UniFi-Controller-IP-Address%:8080/inform

# Command with an example IP address to let the UniFi Controller know the AP is ready for adoption
set-inform http://192.168.10.1:8080/inform

Wrap up

So this is my blog post about informing and adopting an UniFi access point by an UniFi Controller. Hopefully, it is useful for somebody, please respond below if you have any comments or additional information! See you next time! 🙂

NSX Advanced Load Balancer Data Network Issue

0

When configuring the NSX Advanced Load Balancer for some testing in my Home Lab. I noticed something odd related to the service engines management network and data network settings. After thinking I was crazy… I saw an issue in the interface surrounding the data network configuration which caused the issue. In this short blog post, I will explain what was happening and how to resolve the issue.

Environment

My Home Lab environment was running the following products:

Note: Licenses are provided by the vExpert program (this also includes the NSX Advanced Load Balancer licenses for lab usage).

Data Network Issue

At first, we will go to the location in the interface that causes the issue:

  1. Log in on the web interface.
  2. Navigate to “Infrastructure > Cloud Resources > Service Engine Group“.
  3. Click for example on the “Default-Group” (depending on your configuration).
  4. Go to the section “Placement“.
  5. Check the following setting “Override Data Network“.
  6. Select a network that you want…

Sounds all good so far… but look at the description popup on the last screenshot. Are we configuring the management or data network for the service engines? Because the description and the field tell something different.

Management Network or Data Network?

After verifying what happened to the service engines in the group the management network for the Service Engines is changed. This was noticeable to me because the service engines were not reachable anymore on the management network for the controller.

My conclusion after some testing was that the description field is correct. This setting changes the management network!

How can you verify the changes to the service engine group?

Option 01:

  1. Open a command prompt.
  2. Run the following command “ping %management-ip-address service engine%“.
  3. They are probably not available anymore because they are on the wrong network.

Option 02:

  1. Navigate to the vCenter Server.
  2. Login with your account.
  3. Select the Service Engine virtual machine belonging to the group where you configured this setting.
  4. Check the virtual network cards.
  5. There the management network card is assigned to the “override data network” network.

Wrapup

So that was my blog post about the service engine group data network issue. I hope it was useful for somebody because it took me some hours to figure it out…

This wraps up the blog article hopefully it is useful for somebody, please respond below if you have any comments or additional information! See you next time! 🙂

vRealize Log Insight Domain Login Problem

0

Today a blog post about vRealize Log Insight domain login problems. After some time I wanted to check my vRealize Log Insight instance but somehow the domain authentication was not working anymore. So it was time for a new blog post about this issue.

Environment

The vRealize Log Insight instance is deployed in my 24×7 Lab environment that is running vExpert licenses. I am analyzing my logging and checking my login attempts in vRealize Log Insight.

So I am running the following version but I have seen this issue reoccurring in the last years:

  • VMware vRealize Log Insight 8.X (vRLI) (my screenshots are from version 8.8.2).
  • Windows Server 2022 Domain Controllers (as domain connected to vRealize Log Insight)

Problem

So let’s start with the actual problem. At first, the domain login is working for months… nothing strange and everything is fine but then one day it doesn’t work anymore. A vRealize Log Insight cluster restart doesn’t help nor do other basic troubleshooting steps. The local account like the admin account is still working, SSH access is also still working. So it is related to the domain accounts that are provided by my Active Directory.

Here is my configuration and screenshots of the domain login problem issue:

Fix

Now it is time to fix the issue. As always not difficult unless you know what is going wrong.

So let’s start with the actual problem, the problem is that every year the certificates of the domain controllers are replaced by my Certificate Authority and extended by a year. At that moment vRealize Log Insight doesn’t trust the domain controllers anymore as a login source.

So how do we fix it? By adding and trusting the new certificate on the vRealize Log Insight appliance. Luckily this can be done with the GUI so it is straightforward.

Procedure

  1. Log in as the local “admin” account on the vRealize Log Insight appliance web interface (TCP 443).
  2. Go to the following location “Configuration > Authentication > Active Directory”.
  3. Click on the following button “Test Connection“.
  4. Accept all the offered certificates.
  5. This must result in the green text “Succeeded“.

Now try to log in again with a domain account, this should be working again (for another year in my case).

Wrapup

So that was my blog post about the vRealize Log Insight domain login problems. I hope it was useful for somebody because I always run into this issue. It happens in my Lab but also with customers that are using the Active Directory integration.

This wraps up the blog article hopefully it is useful for somebody, please respond below if you have any comments or additional information! See you next time! 🙂

HPE ProLiant Removing SD Card iLO Degraded

2

Recently I was removing an SD card from one of my lab servers but after removing it, the server kept complaining about it. The HPE ProLiant is equipped with HPE Integrated Lights-Out (iLO). This is an out-of-band management system to manage and configure the server. It also is responsible for monitoring the components inside the server.

This means it also monitors the health state of the SD card that is located on the motherboard slot. So when I removed the SD card it just kept checking the health of the component and causing health alerts.

In this blog post, I going to explain what I did to reset the HPE iLO to stop it from monitoring the SD card after permanent removal.

Environment

Here is a short list of information about the HPE ProLiant system that I used for this blog post:

  • Hardware: HPE Proliant DL360e Gen 8
  • HPE ilO version: 4
  • HPE SD card: HP 32GB SD card / Part nr: 700135-001
  • Firmware: HPE iLO version: 2.78
  • Software: VMware ESXi 7.0.3

Location – SD Card

To make the blog post complete I added the motherboard drawing from the HPE manual. The SD card slot is located on the HPE ProLiant DL360e Gen 8 motherboard and the slot is located at number 29 in the drawing below.

Problem – Removing SD card causes degraded state

The issue occurred when the SD card failed. After the SD card failure, I removed the SD card from the system and moved to an SSD-based boot media for VMware ESXi.

I performed some basic troubleshooting like removing the power from the server and restarting the HPE iLO but the health status was still degraded and it was still searching for the SD card.

Here are the error messages in the interface:

  • Error message on the login page: iLO Self-Test report a problem with: Embedded Flash/SD-CARD. View details on Diagnostics page.
  • Error message on diagnostics: Controller firmware revision 2.10.00 NAND read failure

Here are some screenshots related to the error messages:

Resolving – Resetting the SD card slot

Resolving the issue isn’t partially hard… if you know which buttons to push and in what order ;). Before starting, make sure the SD card is removed from the system and that the iLO has been rebooted.

To make sure that everything just works directly… open a clean browser and login into the iLO and directly follow the procedure described below.

Closing words

In the end, it cost me about three hours to get it fixed. The reason why I wanted it so badly fixed was that it kept triggering my monitoring system and that drove me crazy. This server in particular powers on and powers off regularly and during every power cycle, the health state resets and triggers monitoring alerts.

Digitus Patch Cabinet Covering Fan Holes

0

For the last couple of months, I was busy making my new patch cabinets ready for use. One of the things I noticed with the Digitus patch cabinet is that there are openings on the top by default for the fan installation (fan holes/mounting holes). This is great for people that install the optional fan kit from Digitus but not everyone needs active fans and it is about 210/230 euros.

When you do not install the optional fan kit you will run the following problem… dust! The openings and holes on top of the cabinet allow dust to fall into the cabinet on top of your patch panels and switches. When cleaning the cabinet you need to be careful so you do not swipe the dust into large fan mounting holes and bolt hols.

So it was time to look for a solution without buying the Digitus expensive optional fan kit for basically no reason in my case… One of my requirements was no drilling or modifying of the cabinet because that would inevitably block me from installing the fan kit (in case I ever need them).

Part List

So let’s get started here is an overview of the part that I ordered online for one enclosure:

  • 2x Fan Filter (AABCOOLING Plastic Filter 120 Black OFG016 @ Amazon)
  • 8x Bolt (Bolt m5x12mm @ RVSpaleis)
  • 8x Nut (Nut with locking @ RVSpaleis)
  • 12x Plastic covers for 5 mm holes (Premium Afdekdopjes voor Boorgaten (specifications: 5 mm / RAL 9005 black) @ UwCover.nl)
  • Total costs: ~ 30 euro
  • Saving: ~ 220 – 30 = 190 euro
  • Percentage: ~ 86%

Keep in mind:

  • The items were ordered in The Netherlands (Yes, it is a country on planet earth).
  • The items were ordered in June 2022.
  • The prices might change over time.

Photos

In my home, I have two of the same Digitus Patch Cabinets mounted next to each other. That is why some of the pictures look double ;). No worries you do not have to go to the optometrist!

So here is a photo of the top side of the patch cabinet before the installation, as you can see large holes that attract a lot of dust. As you can see there are bolt holes and fan holes. Both of those we are going to cover up.

Here is a list of the parts that I ordered: Some basic product images to give you an idea of what you need. The links to the webshop are listed in the parts list.

Here are the photos when installing the parts for covering the fan holes in the cabinet. The last picture is the final result of both patch cabinets in a row.

So here is the result after installing all the components on both of the patch cabinets, the fan holes and bolt holes are covered and no dust gets in anymore:

Wrapup

In my opinion quite a nice retrofit for the Digitus patch cabinet and not too expensive. The nice thing is you can just remove the fan covering and everything is back to stock. This makes it possible to install the Digitus fan kit unit at a later stage without limiting yourself.

NLVMUG 2022 Event

0

Today a blog about the NLVMUG 2022 event, which I attended on the fourteenth of June 2022. The event took place in the DeFabrique in Utrecht The Netherlands.

Lots of parking spaces and easy to reach as it is centrally located in the country. The location was the same location used for the NLVMUG in 2019 (the last physical VMUG before COVID).

For me personally, this was my first physical industry event since VMworld 2019 in Barcelona Spain. So it was great to be back at a physical conference and to actually meet up with a lot of familiar faces such as ITQ/VMware colleges and community members.

There was a great lineup and a lot of sessions you could choose from. Here is an overview of the available sessions of the NLVMUG 2022:

I personally attended a couple of sessions, as you can see in the photos below. Overall the sessions were good quality and with great content! Very nice to see that a lot of people love to share and spend time on prepare those sessions!

NLVMUG 2022 Photos:

I took some photos of the event to share on my blog to give people an idea of what a VMUG is and maybe inspire them to join the next NLVMUG in 2023 (if there isn’t a new … virus or something else).

So this wraps up my short blog post about the NLVMUG 2022. I would like to thank the NLVMUG team and my employer (ITQ) for making it possible for me to be there!

For me the next physical event will be VMworld … VMware Explore so maybe see you there? See you next time!
