3 hours = worlds longest command line

This was on one line, thought I would share it with everyone:

msdeploy -verb:sync -source:"metakey=lm/w3svc/571459,computername=server1" -dest:"metakey=lm/w3svc/2989,computername=server2" -skip:"objectName=metaProperty,attributes.name=LogFileDirectory" -skip:"objectName=metaProperty,attributes.name=SSLStoreName" -skip:"objectName=metaProperty,attributes.name=SSLCertHash" -skip:"objectName=metaProperty,attributes.name=SSLStoreName" -skip:"objectName=metaProperty,attributes.name=ServerBindings" -skip:"objectName=metaKey,attributes.path=blahTOBlah" -skip:"objectName=metaKey,attributes.path=HTTPtoHTPPS" -skip:"objectName=metaKey,attributes.path=redirectToBLAH" -skip:"objectName=metaProperty,attributes.name=AppFriendlyName" -skip:"objectName=metaProperty,attributes.name=SecureBindings" -skip:skipAction=delete -replace:"objectName=metaProperty,match=m:\websitelocation1,replace=x:\websitelocation1" -replace:"objectName=metaProperty,targetAttributeName=value,match=apppool2\.0,replace=apppool" -replace:"objectName=dirPath,match=m:\website1,replace=x:\website" -enableLink:AppPool -disableLink:ContentExtension -whatif > msdeploysync.log

Microsoft finally follows it's own RFC... now stuff is broken.

We have a web service that goes out and talks to other web services. Our web service and the other ones are protected by firewalls, as we don't want just anyone hitting our web services. As we move to windows 2008 r2, we noticed something funny was happening..... our connections were being blocked.
Turns out that Microsoft is finally following their own RFC and it is breaking things.  Windows servers now will use the "IP address most closely matching the gateway" to decide what IP address to use as the default one.  So now our webservice was using the "lowest" ip address we had, which was for a site that had nothing to do with the webservice.
I found out I wasn't alone being surprised by this new "feature" and found that there is a workaround.
In short, you need to:
-Download and apply the hofix. (the MS extractor was currupt, so I used 7zip to extract the files)
-Reboot for the hotfix to take effect.
-Gather a list of all your IP addresses on that machine, take out the one you want to be the "default IP." Put them in the variable $currentIPs.  Then you can run the script as below, it will remove and add the IPs all at once with little downtime.

I forgot to remote desktop using the FQDN, so I was disconnected, but when I reconnected everything was happy.


$currentIps = "10.1.1.1","10.1.1.2","10.1.1.3","10.1.1.4"


foreach ($ip in $currentIps){

netsh interface ip delete address public $ip
write-host "$ip deleted"
netsh interface ip add address "public" $ip 255.255.255.0 skipassource=true
write-host "$ip added"
}
Write-Host "I suggest you reboot your server now, just in case."


Notice the "skipassource=true."  This will not work before the hotfix.  Again you do not want to run that parameter with your IP address that you DO want to be the default one.
(My Subnet mask is 255.255.255.0, if yours is different, then change it above.)

Windows Auditing can be annoying. (Shut up already)

My audit logs were filling up with a bunch of B.S. from perfectly good packets being successfully sent and received. (event id 5157, and 5152) By default, Windows thinks you want all of these packets logged... and perhaps some admins do. But they can be logged in the firewall log, I don't want them in the event log too. (Default location of the Windows Firewall log is at "C:\Windows\system32\LogFiles\Firewall\pfirewall.log") So after a bunch of googleing, I found several answers that almost worked. Here is what really worked for me on Windows 2008 R2 and R1:


auditpol /set /subcategory:"Filtering Platform Packet Drop" /success:disable /failure:disable

auditpol /set /subcategory:"Filtering Platform Connection" /success:disable /failure:disable

So there you go, save some audit log space for something that matters, like non-firewall stuff.
-Bryan

(oh, and one more thing, if you want to create a Group policy for this, it is under
computer configuration --> policies --> windows settings --> security settings --> advanced audit policy configuration --> audit policies --> object access. Then double click "Audit Filtering Platform Connection" and check only the box next to "configure the following audit events." DO NOT CLICK THE OTHER TWO BOXES. Repeat for "Audit Filtering Platform Packet Drop" too. If this does not work, edit your GPO to include the policy outlined in Method 1, steps 2 and 3 from http://support.microsoft.com/kb/921468 .  REMEMBER, THE GPO MIGHT TAKE SOME TIME, so if you don't reboot, give it at least 90 min before you give up on the GPO idea.)

Social Engineering, be careful what you ask for.

After planning on the trip to Vegas involving a unique idea with friends, I learned some things: (vagueness is purposeful as to not give too much away, this was in Vegas after all)
1) sometimes people will inherently trust or hate you based upon only what you are wearing.
2) Everyone likes to hang around with someone who is having a good time that is considered someone who shouldn't/can't.
3) Combined with #1, if you listen, people will speak to you.
4) Sometimes people just need to speak about their problems, even if the foundation of their trust is a lie. See #1. No matter what the trust is based on, it will still make them feel better.
5) By hearing other people's problems, it will probably make your problems seem smaller in comparison.
6) Everyone loves a man in a uniform.
7) Sometimes the best person to convince others to become religious is an atheist.
8) Margarita salt is not crack rock, no matter what crazy ladies tell you on the street corner.
9) No one wants to hit a father, or hit on, or be hit on by.
10) Everyone is curious about Buddhism, so will believe anything.... even if it is nothing.
11) If you are going to wear it, go all the way.
12) Lesbians are ok with men of the cloth, as long as they stay that way. But their friends might be ok with some change.
13) Photo bombing is not a sin if you are the judge of sin.
14) Hooters waitresses are usually nice girls who just need a job.
15) A priest who is having trouble walking is more convincing than a priest with communion wine bottle on his own two feet.
16) Motorcycles are still awesome.

Install IIS and other IIS stuff on Server or a Desktop

I searched around, and didn't find anyone who had a way to install IIS from POSH. And if they got close, they didn't say that it didnt work on a server, or a desktop depending on the script. So here is one that will work on both, depending on what the user says they have:

App pool restart using POSH

We sometimes want to restart an app pool on a server that is either misbehaving, or coud be locked up.  Here is a script to return all the app pools that are running on the server you specify, and enables you to restart just the app pool you want. This is my raw script, including some code I was expirementing with at the end of the script.

#############################################################################################
#
#Simple script to recycle an app pool of the User's choice on the server of the user's choice
#
# May 24, 2010
#Bryan Loveless 
#
#This must have PowerShell v2 or newer, find it at http://support.microsoft.com/kb/968929 if
# running win2k r1 or earlier. run Get-host if you are not sure what version you have.
# AS OF THIS DATE, THIS SCRIP MUST NOT USE POWERGUI, USE ISE TO MODIFY OR RUN.
#
#############################################################################################
#import-module webAdministration

#get servername to restart the pools on
$servername = Read-Host "Enter the name of the server to restart the pools on."

#connect to the server listed above
$connection = New-PSSession -ComputerName $servername 

#incase there are mutiple machines listed, this should keep track of them all (future implementation)
$psall = Get-PSSession

Write-Host "Here are the avalible app pools on the server you selected."

# run the command to see what app pools there are, but not enter the session yet.
# invoke-command -ComputerName $servername {get-wmiobject -namespace "root\MicrosoftIISv2" -class "IIsApplicationPool"} 


#Enter-PSSession -ComputerName $severname  #this way doesnt seem to work, see line below
# $connection | Enter-PSSession
Enter-PSSession -Session $connection

# tried a wait event to establish the connection, didn't work
# wait-event -timeout 5


#perhaps above return just the app pool name and status?
$pools= (get-wmiobject -namespace "root\MicrosoftIISv2" -class "IIsApplicationPool")

foreach($item in $pools)
{
 Write-Host $item.name
 Write-Host $item.status

}


$apppoolname = Read-Host "What is the name of the app pool you want to restart?"

#entering the session above so we can see the apps running
#Enter-PSSession -ComputerName $severname

#$appPoolName = $args[0]
$appPool = (get-wmiobject -namespace "root\MicrosoftIISv2" -class "IIsApplicationPool" | Where-Object {$_.Name -eq "W3SVC/APPPOOLS/$appPoolName"})

# it doesnt like to "restart" pools that are stopped, so I will stop and start them instead of recycle
# $appPool.Recycle()
$appPool.Stop()
$appPool.Start()


#end the connection to the server above
Exit-PSSession 
#Remove-PSSession -session $psall

#to help close sessions while coding
#$psall = Get-PSSession
#Remove-PSSession $psall

#Other interesting things that can be done with this variable once declared:
#
#EnumAppsInPool      Method       System.Management.ManagementBaseObject Enum...
#Recycle             Method       System.Management.ManagementBaseObject Recy...
#Start               Method       System.Management.ManagementBaseObject Start()
#Stop                Method       System.Management.ManagementBaseObject Stop()
#Caption             Property     System.String Caption {get;set;}
#Description         Property     System.String Description {get;set;}
#InstallDate         Property     System.String InstallDate {get;set;}
#Name                Property     System.String Name {get;set;}
#Status              Property     System.String Status {get;set;}
#

#Another interesting bit of code to borrow:
#function recycle-pool($strServerName)
#{
#    $objWMI = [WmiSearcher] "Select * From IIsApplicationPool"
#    $objWMI.Scope.Path = "\\" + $strServerName + "\root\microsoftiisv2"
#    $objWMI.Scope.Options.Authentication = 6
#    $pools = $objWMI.Get()
#    foreach ($pool in $pools)
#    {
#        $pool.recycle()
#        if (!$?)
#        {
#            Write-Host $pool.name " - ERROR"
#        }
#        else
#        {
#            Write-Host $pool.name " - Recycled"
#        }
#}


Using POSH to shutdown machines quickly

We were having some electrical issues in our building, and I wanted to have a script that would shutdown all of our test, dev, and QA machines in a hurry to preserve the remaining UPS power for the production machines. Below is a simple script I wrote to shutdown a predefined list of machines quickly:

----------------------------
###########################################################################
#
# Shutdown Test and Dev servers
#
# Created Aug 27, 2010
# Bryan Loveless 
# 
#
#
# Requires Powershell 2.0
#
# Change your Execution policy to RemoteSigned if running locally
# by: Set-executionpolicy -executionpolicy RemoteSigned
#

#
#
###########################################################################





$Victims="devserverWINSname1","testserverWINSname1","devserverWINSname2"

$shutdownjob = stop-computer -computername $victims -throttlelimit 5 AsJob 
#throttle limit is how many commands to send at once, this can be many, many more than 5 if you wish

Write-Host $shutdownjob



Run this script and  those machines named will be down before you know it.
