Script for vSwitch change security settings

Going to start working on this script, but if someone knows, is one year, I'd be interested.  Trying to create a script that changes the vSwitch 'Change of address' security settings and "forged passes" to "Reject" to all on the host's vSwitches.  I would like the script to turn to a CSV with a list of ESX servers, so that the script should authenticate directly on the ESX Server.  Thank you.

Yes, you need a header row in the CSV file

Move invites him outside of the loop, something like this

$rootpassword = Read-Host -AsSecureString -Prompt "Enter the root password"

Import-Csv "C:\esxnames.csv" -UseCulture | %{
    Connect-Viserver $_.Name -user root -password $rootpassword 

    $esx = Get-View -ViewType HostSystem -Filter @{"Name"=$_.Name}
    $NetworkSystem = Get-View $esx.ConfigManager.NetworkSystem
    foreach ($sw in $NetworkSystem.Networkconfig.Vswitch){
        $swspec = $sw.spec
        $swspec.policy.security.AllowPromiscuous=$false        $swspec.policy.security.ForgedTransmits=$false        $swspec.policy.security.MacChanges=$false        $NetworkSystem.UpdateVirtualSwitch($sw.name,$swspec)
    }

    Disconnect-VIServer -Server $_.Name -Confirm:$false}

  • Tried to change the security settings in XP on some of my documents, now I can't access

    original title: describe the security settings

    Hi, I stupidly tried to change security settings on some of my documents, now I can't access then more... don't know what I've donebut would be able to open them again...

    the files are stored on an external hard drive, but I always use the original laptop running xp... He is using that file names are now show green...

    Thanks for any help you can give.

    Speedy

    If the file names displayed in green, an indication that the files are encrypted using the Encrypting File System (EFS) in XP Pro.  The encryption key to decrypt these files is stored in your certificate store on the machine/user name that originally encrypted the files.  To access these files, you must connect to the original machine which them encrypted and access it using the same user.  If the encryption certificate is lost or damaged, then you permanently lose access to your files.  For more information, start with this article:

    "Best practices for EFS file system.
      <>http://support.Microsoft.com/kb/223316 >

    As you have discovered, EFS can be dangerous.  Use it carefully and always save your article above encryption certificate.

  • How to change the security settings on a wireless network

    I would change the existing network security settings to WPA2, AES, or at least from TKIP AES.

    I am familiar with access via browser to the router and how to change the settings of the router.

    My question is how to make this as painless as possible for the network.  Step by step would be great

    First of all, I guess I have to change the settings of the router using the computer running Easy Link Advisor?

    Do I then have to disconnect/reconnect this computer?

    Do I have to unplug all the other computers and then sign in again with the update settings?

    The change of security settings affect my print server?  If so, I put up from scratch in ELA?

    For the record, I have a WRT 300N and the print server is a 54g.

    Anyone who reads this can also focus on recent news.  Maybe not a big deal, but a WPA/TKIP vulnerabilities has been identified.

    Thanks in advance to anyone who responds.

    If you change the router's wireless security settings, it will affect all devices that connect wireless to the router. To change the settings, simply set until you want on the web interface of the router. Save the settings. You need not link to that Advisor. Direct access to the web interface of the router is sufficient and preferable.

    All devices configured to connect to this network should ask if they connect more. It depends on type of what you had before. If you have not used WPA2 or WPA before having to ask for the password. If you used the WPA or WPA2 with the same password that they cannot even ask the password. How it works in detail with a specific wireless device depends on the device and the software you use. Some devices may require you to first remove the network wireless in the list of "preferred networks" and then reconnect.

    Check the manual of the print server how to configure for the new security settings. You should be able to reconfigure the print server through a web interface. First, it is probably best to change the settings on the print server and then make the change on the router. Otherwise, you may have a hard time, connection to the print server to make the change. In addition, depending on how old the print server is that it cannot even support WPA2 and AES.

    I can't download Microsoft software because of my security settings.  I can't download anything, including the windows installer because my security settings see them as harmful to the computer.  I did everything suggested by the help windows, but apparently not good things.  What should I change?  At the beginning I had some success downloaded from Safari, but now, even the last program was blocked at the end of the download preventing installation of your own program.  Mystifies me.   Any suggestions?

    Hello

    ·         What exactly happens when you try to download?

    ·         Are you facing problems with the download of Internet Explorer as well?

    ·         You receive an error message when downloading?

    ·         Security are what you referring?

     

    You can try to Disable Antivirus software and firewall on the system temporarily and check if that helps resolve the issue.

    Note:

    Disable Antivirus software and firewall is a potential threat to the system, I suggest you to activate their return once you have completed the troubleshooting steps.

    If you receive the error message: your current security settings do not allow this file to download. When downloading then this problem occurs because the Internet Explorer file download option security zone is set to disable.

    To allow downloading files option refers to the procedure described below.

    (a) open Internet Explorer.

    (b) press the Alt key and then click on tools in the menu bar.

    (c) select Internet options in the menu drop-down.

  • Security settings won't let JavaScript not even open a document?

    Yes, I know that this issue has been covered a hundred times or more in this forum.  I'm also sorry for adding to the list of those who don't understand, but...  Well, I don't understand.

    I am very familiar with JavaScript and ExtendScript.  I have turned it on in my copy of Acrobat X Pro and may seem to run simple commands in the Console of the JavaScript debugger, as "3 + 4".  However, when I try to do something that seems trivial, such as opening a document thusly:

    var document = app.openDoc("/Volumes/g/ ArtDept/Product Templates/ ProofCover/proof_cover.pdf");
    

    The debugger console gives me error that has ravaged thousands of the Acrobat Scripting Guys:

    NotAllowedError: Security settings prevent access to this property or method.
    App.openDoc:1:Console undefined:Exec
    

    So can you please explain to me, in plain language, what means this error and, more importantly, how I can bypass it.  I don't want to run a script to the folder level, since, from what I read, those that are performed at the launch of Acrobat.  Ideal for adding menu items to Acrobt, but not for what I need.  Instead, I want this code to be called from an InDesign script to automate a simple task in Acrobat.

    May be it someone please guide me through what I need to do to get this simple task "being"?  Or, at least, point me to a resource that can guide me through it?

    My guess is the path you are using is incorrect. Try to open the file

    manually and then executing code from the JS console:

    This.Path

    See if the result is identical to the one you are trying to open...

    PS - There is no limitation on the path to the file when you try to open it,

    only when you try to save a file under a new name.

  • change the settings of harvest with the actiondescriptor code tool

    I would like to make aid - in fact I'm looking for a code outright, because I was not able to understand.

    These parameters are the tool options. Although you can get the parameters of the current tool I've ever been able to find a way to put them directly via the script. To change these settings, you will need to create, load and select predefined tools.

  • Script to change the settings for security vSwith

    We need a script to change the settings for security vSwitch.

    To change the below: -.

    Mac changes Accept Reject

    Forged pass Accept Reject

    The two parameters above must change on all the vSwitch in vcenter.

    Altogether. Pass an argument to Get-VMHost

    If you pass the complete hostname (as he shows in vCenter), it will act on the single host:

    Get-VMHost MYESXi01.mydomain.com

    or if you want to do more, you can pass a joker:

    Get-VMHost MYESXi*.mydomain .com

    FWIW, I think that should do the same thing on a single line, if you like this better

    Get-VMhost|%{$hv=Get-View $_.ID;$ns=$hv.ConfigManager.NetworkSystem;($hv.Config.Network.Vswitch)|%{$vs=$_.Spec;$vs.Policy.Security.AllowPromiscuous=$false;$vs.Policy.Security.ForgedTransmits=$false; $vs.Policy.Security.MacChanges=$false;$ns.UpdateVirtualSwitch($_.Name,$vs)}}

  • How to change the security settings for a particular Web site?

    I'm big fan of airplanes. There is a website: www.passur.com, which gives real-time traffic on some of the airports we. For example, the link: www4.passur.com/jfk gives all traffic inbound and outbound to and from JFK airport. This page requires Java. I installed it and everything was OK. But for some time - 2-3 months - whenever I try to open and watch the traffic there is message saying 'blocked application' and in the message from the Inbox is written - on the first line "name: has '; on the second line ' location: www4.passur.com'; " on the third (last) row is written "your security settings have blocked an application not approved to run." and on the bottom right there is a button 'OK '. The question is to know how to unlock it and display the Web page. Thanks in advance.
