Amazon Web Services – Configure Password Policy with AWS CLI

aws iam update-account-password-policy –minimum-password-length 8 –require-uppercase-characters –require-lowercase-characters –require-numbers –no-require-symbols –max-password-age 60 –hard-expiry –allow-users-to-change-password –password-reuse-prevention 24
VMware ESXi 6.7 – View the ARP Table
Recently, I needed to select the Internet Protocol (IP) addresses for various VMkernel adapters. In selecting IP addresses you must be certain that the IP address is not already in use to avoid an IP address conflict. One way to determine this is to ping the IP address in question. However, what do you do if ICMP traffic is filtered?
In that case, you can ping the IP address in question from another host on the subnet and view it’s Address Resolution Protocol (ARP) table. The command below may be used to view the ARP table of a VMware ESXi 6.7 host.
esxcli network ip neighbor list
Microsoft Windows Command Prompt – Configure Network Settings
You may use the following commands from the Windows command prompt to configure the IP address and DNS server of a server running Microsoft Windows Server 2016 Standard. You will need to modify the name of the network interface card, IP address, subnet mask, default gateway, and DNS server.
netsh
interface ip set address name=”ethernet” static 10.0.25.100 255.255.255.0 10.0.25.1
interface ip set dns “ethernet” static 10.0.50.100
interface ip show config
exit

Microsoft Active Directory – Add-Computer Cmdlet
You may use the following Windows PowerShell cmdlet to add a host to a Microsoft Active Directory domain with a specific domain controller. You will need to substitute the DOMAIN parameter with the actual domain name.
Add-Computer -DomainName DOMAIN -Server DOMAIN\DC01
Microsoft Active Directory – Trust Relationship Failure with Primary Domain
If you’ve worked with Microsoft Active Directory, then it’s very likely you’ve seen the following error message while trying to login to a server or workstation using domain credentials: “The trust relationship between this workstation and the primary domain failed.”
Typically, this is resolved by removing the server or workstation from the domain then rejoining it to the domain. However, the Reset-ComputerMachinePassword cmdlet may be used to change the computer account password that the computer uses to authenticate to domain controllers in the domain. For example, you may use the following syntax: Reset-ComputerMachinePassword -Server DC01 -Credential DOMAIN\– USER. As this is an example, you’ll need to substitute the DC01 field with a domain controller in your Microsoft Active Directory domain. Additionally, you’ll need to substitute the DOMAIN\– USER field with the domain and username of a user in your Microsoft Active Directory domain.
I believe this solution is preferable due to the fact that the Microsoft Active Directory computer object continues to use the same SID, remains in the appropriate OU, and remains in any necessary groups.
More information on this cmdlet may be found here.
Amazon Web Services – Verify AWS CLI Installation
You may use the following link to receive instructions on installing the AWS CLI. Additionally, to verify the installation, navigate to C:\Program Files\Amazon\AWSCLI for x64 operating systems and C:\Program Files (x86)\Amazon\AWSCLI for x86 operating systems.
Lastly, you may verify the version of the AWS CLI using the aws –version command from a Windows Command Prompt or Windows PowerShell session.
