Power shell connectivity issue

sooraj123 — Fri, 04 May 2012 05:00:00 GMT

Hi..

I installed a fresh copy of windows 2008 server R2 and enabled powershell using the following commands..

Enable-PSRemoting

Set-Item WSMan:\localhost\Client\TrustedHosts *

Restart-Service winrm

After that I can connect to the local machine using the command "Enter-PSSession 192.168.1.230"

But I can't connect to it from any other machine using the same command..

Is any other configuration changes needed for it

any help would be appreciable

Thanks in advance

Install .net framework 4 on remote servers

virtuallynothere — Wed, 25 Jan 2012 06:00:00 GMT

Hello,

I am trying to get .net 4 framework installed on remote servers. I have the script pasted below and I keep running into 2 issues.

1. The file will not copy, the file share permissions are fine as I used a separate script that just copies the installer to the remote servers, but in this script the copy fails.

2. The install of .net framework fails with exit code 5 and I am not sure why.

[ScriptBlock] $script = {
    #$ErrorActionPreference = "Stop"
    $MachineName= gc env:computername
    C:\Windows\System32\net.exe use Z: "\\RemoteMachine\SharedFolder\DotnetFrameWork 4.0" password /user:domain\username
    if(!(Test-Path "C:\Temp"))
    {
        New-Item -Path "C:\Temp" -ItemType directory
    }
    Copy-Item -Path "Z:\dotNetFx40_Full_x86_x64.exe" -Destination "C:\Temp" -Force -Recurse    
    function LaunchProcessAndWait([string] $FileName, [string] $CommandLineArgs)
    {
        #preferences
        $ErrorActionPreference="Stop"
        try
        {
            Write-Host "Starting process $FileName on machine $($MachineName)"
            $p = Start-Process -FilePath $FileName -ArgumentList $CommandLineArgs -Wait -PassThru
            Write-Host "The process $FileName exit code is $($p.exitcode)"
            return $p.ExitCode            
        }
        catch
        {
            Write-Host "Error launching process $FileName"
            throw
        }
    }
    LaunchProcessAndWait "C:\Temp\dotNetFx40_Full_x86_x64.exe" "/I /q"
}
$cred = Get-Credential
$sessions = $Hosts | New-PSSession -Credential $cred
Invoke-Command -ScriptBlock $script -Session $sessions
$sessions | Remove-PSSession

Thanks, remoting is enabled and I will verify credssp is enabled as I am not positive about that.

Why would credssp be required for this script if the client computer and destination server are in the same domain and the account used to login and also to run the remote powershell session are both domain admin accounts?

I know credssp is for multi-hop authentication, but it didn't look like that was required in this configuration I am using.

Also, for the file copy portion, I have another script that just copies a file and that works fine being run exactly as I ran this. How does that work? That script is below and I've not had any issues with it.

Import-Csv c:\Scripts\servers.txt | foreach {

$server = $_.name

$location = "\c:\Temp"

Copy-Item "\\server\Applications\dotnet4\dotNetFx40_Full_x86_x64.exe" -Destination $location -Force -ErrorAction silentlyContinue | out-null

if(-not $?)

{

"ERROR: could not copy file(s) to: $server at $location"

}

} | out-file errors.txt

PSRemote Challenge

squeekie — Mon, 24 Oct 2011 05:00:00 GMT

I have a need to copy files from a remote server to another server that will be a scheduled task to run every hour. The files can be quite large so I found that 'robocopy' is the better utility for this case. I have read the post for how to utilize it within powershell and it works great locally.

The challenge:

The remote server is in a DMZ part of a cluster while the other server is located in another subnet (local).

Communication is only one way, from Local to DMZ. (I can copy files up to the server, retrieve files from the server, but I am not able to copy files from the remote server to the local server)

I thought of ps-remote, which works great, I have it configured and I'm able to create sessions, browse, administer etc....

When I launch the robocopy script, it runs it locally of course, but what I need it to do is send those files back to the local server. Is there a possibility to have the script run locally, connect to the remote server with credentials, check for a specific mount point or drive letter if not connect to other server in cluster (I'm reading cluster cmdlts for this task), get the files copied to the local server and repeat the process every hour (task is fine or invoked by a script)

Thanks,
