This is my personal notes on Dell PowerEdge R510 firmware upgrade, when DRAC is not an option.
Catalog update is not working anymore as they are out of support, so R510 is likely not added to catalog.
You need 3 disks
LiveUpdate disk
SBU disk

Ubuntu 20 how to increase swapfile
After installing server, I increased RAM, but swap file remains the same, so I have to increase itrmanually. I increased RAM from $ to 8 GB so I have to increase swap file accordingly. In Ubuntu 20.04 swapfile out of the box is called swap.img not swapfile, so the commands will be as follows:
- type sudo su so you don't have to type sudo before each command
ubuntu@grayflow:~$ sudo su
[sudo] password for ubuntu:
- check swap size and name
root@grayflow:/home/ubuntu# swapon --show
NAME TYPE SIZE USED PRIO
/swap.img file 4G 2.1G -2
- turn off swap
root@grayflow:/home/ubuntu# swapoff -a
- increase swap file

ESXI 5.5 backup and restore with ghettoVCB script
ESXI backup/restore with ghettoVCB script
Valid upon version ESXi 5.5
Before make sure ssh is enabled on your VMware host. SSH and ESXi shell must be enabled.
It would be good idea to add restrictions in VMware firewall to access ssh only from admin computers. ESXi remote shell must be used to create access key, or you have to enter password every time you connect.

Get File Hash on Windows PowerShell
My instructions are for Windows 10, but I am sure it will work on every Windows wirh powershell.
It could be useful for security updates and suspicious executables.
Open PowerShell Windows key->Type PowerShell
Move to the folder where file are placed
cd c:\folder
where your file are located
Get-FileHash .\filename.extension -Algorithm SHA256
or
Get-FileHash .\filename.extension -Algorithm SHA1
Lets say wou want to check Gimp downloaded in c:\temp
Get-FileHash -Path c:\temp\gimp-2.10.0-setup-2.exe -Algorithm SHA256
Thats it.

How to extend linux vm drive and partition and recreate swap file without gparted and without gui
Preface.
HDD which is actually bunch of files in vm, emulating HDD are extended via VMwareVCenter. I need to increase my primary partition in Ubuntu Linux VMware virtual machine. In other words "/" must be extended. In this example parted and fdisk which are preinstalled in all modern linux systems will be used.How to extend root partition /
First we need to extend device. In my situation there are problem- after device /dev/sda1 are /dev/sda2 so I need firstly to move /dev/sda2 to the end of HDD partition.Fdisk shows I can increase /dev/sda2 but cannot /dev/sda1
root@Log:/# fdisk -l
Disk /dev/sda: 450 GiB, 483183820800 bytes, 943718400 sectors
Device Boot Start End Sectors Size Id Type
/dev/sda1 * 2048 615234375 615232328 293.4G 83 Linux
/dev/sda2 617187328 629145599 11958272 5.7G 82 Linux swap / Solaris
As you can see there are 943 mil sectors but only 629 occupied.
So I first need to move swap to the end of disk.
Move swap partition
All commands must be typed as root user, in ubuntu type sudo su or type sudo before each command. Before deleting swap partition, stop all active applications like database and web servers. After moving swap partition must be at the end of disk /dev/sdaType fdisk /dev/sda and then type
p to print info about partitions
d to delete swap partition
2 number of partition
n to create new partition
p to make partition primary
2 number of partition
calculate sectors, partition take, subtract from the last sector and provide to numbers First sector of partition and last sector. Some spreadsheet could help.

Upgrade Windows 2012 R2 Root CA from SHA1 to SHA256
How to update Windows 2012 R2 AD CA from SHA1 to SHA2 or SHA256
Windows 2012 R2 Active Directory integrated by default publish and issue SHA1 certificates, which is now declared as untrusted by Google Chrome. There was warning window during configuration, but who knows it so important, after it is already intergrated you can discover you forget to change default hash algorithm.Windows 2012 R2 out of the box provider is already MS Software Key Storage Provider so you don't have to convert something. It is out of this article, how to install nginx, CA or IIS. To convert storage provider, seek for more complex technet articles like this.
Conversion of CA hash algorithm
To convert Certification Authority and web server certificates form sha1 to SHA 256 it is pretty simple but not so well documented.To convert Certification Authority you just have to type one command. Go to Administrator command prompt.
certutil -setreg ca\csp\CNGHashAlgorithm SHA256
How to Issue Windows 2012 R2 CA sha256 trusted certificate to Graylog ubuntu nginx or apache web server
A little bit more complex is request key from linux for nginx or apache server. I already had self signed certificate, but from linux perspective, request is almost the same. To avoid exposure of API and port 9000 I am keeping nginx proxy on graylog server. My nginx configuration is as follows, as you can see, there is nothing changed from graylog perspective.
