jimfdavies / pingsweep.ps1

Created February 21, 2013 09:57

Quick script to ping a subnet and report if each IP address is used or 'empty'. Can be extended to redirect to a file if desired.

	$subnet24 = "10.10.1"

	1..254 \|
	foreach-object {
	$ip = $subnet24 + "." + $_
	if (test-connection $ip -count 1 -quiet) { Write-Host "USED:$ip" } else { Write-Host "EMPT:$ip" }
	}

	#USED:10.10.2.1
	#EMPT:10.10.2.2

Last active September 28, 2018 14:06

Quick example for Fog VSphere provider. Lists VMs in a given folder in a given DC.

	#!/usr/bin/env ruby

	require 'rubygems'
	require 'pp'
	require 'fog'
	require 'highline/import'

	def get_password(prompt="Enter password:")
	ask(prompt) {\|q\| q.echo = false}
	end

jimfdavies / Get-OSTypeFromTemplate.ps1

Created February 11, 2013 14:39

Get-OSTypeFromTemplate returns the VSphere API 'ostype' from a defined template. This can be used to build out an OS Customisation Specification when deploying a new VM from template. Easily extensible for other OSes or more specific flavors. If the template does not give up its secrets, the script stops and waits for you to type it in.

	Function Get-OSTypeFromTemplate {
	param($templatename)

	$templateview=get-view -id (get-template -Name $templatename).id
	switch -wildcard ($templateview.Guest.GuestFullName)
	{
	"Windows" { $ostype = "Windows" }
	"Linux" { $ostype = "Linux" }
	default { $ostype = Read-Host "Unable to determine OS from template $templatename. Enter the word Linux or Windows here" }
	}

jimfdavies / Get-GatewayFromIPAddress.ps1

Created February 11, 2013 14:29

Get-GatewayFromIPAddress returns your IP gateway from your IP address. This assumes that your default gateway is on the same /24 subnet and its node address is .1 (configurable). Useful for automatic deployment scripts.

	Function Get-GatewayFromIPAddress {
	param($ipaddress)

	$routerip = ".1"
	$gateway = (($ipaddress.Split("."))[0..2] -join ".") + $routerip
	return $gateway
	}

	$ipaddress = "10.1.2.100"
	$gateway = Get-GatewayFromIPAddress -ipaddress $ipaddress

jimfdavies / Get-DomainFromFQDN.ps1

Last active September 28, 2018 14:06

Get-DomainFromFQDN return the domain portion of a Fully-Qualified Hostname. This is currently limited to 4 sub-domains but the array selection could easily be extended to use the length of the array if appropriate. Useful for automatic deployment scripts.

	Function Get-DomainFromFQDN {
	param($fqdn)

	$vmdomain = ($fqdn.split("."))[1..4]
	$vmdomain = $vmdomain -join "."
	return $vmdomain
	}

	$fqdn = "myhost.my.domain.local"
	$domain = Get-DomainFromFQDN -fqdn $fqdn
