Help on running plink for multiple servers.

Sorry for posting here but I am sure the Master LucD will help me on this.

Please correct me on this code.

When I execute without using for loop for importing servers the command is executing successfully but while adding forloop its failing with below error.

$CSVPath ='C:\IDRAC.csv'

foreach($row in Import-Csv -Path $CSVPath){

$User = 'root'

$Pswd = 'Test@1234'

$hst = $row.IDRAC

$plink = "D:\plink.exe"  # Plink Path

$plinkoptions = " -v -batch -pw $Pswd"

$cmd = @'

racadm config -g cfgUserAdmin -o cfgUserAdminPassword -i 2 Test@12345

'@

$remoteCommand = '"' + $cmd + '"'

foreach ($hstpwdchange in $hst) {

$command = $plink + " " + $plinkoptions + " " + $User + "@" + $hstpwdchange + " " + $remoteCommand

$result = Invoke-Expression -command $command

"" | select @{N="Executed On IDRAC";E={$hstpwdchange}},

    @{N="Result";E={$result}}

}

}

#racadm set iDRAC.Users.2.Password "Test@1234"

You might want to try the 'echo Y' trick. Alan documented that in SSH PowerShell tricks with plink.exe.

From the error it looks like the host key is not yet in your system

No LuckSmiley Sad Same Error

Tried like this

$command = "echo Y | " + $plink + " " + $plinkoptions + " " + $User + "@" + $hstpwdchange + " " + $remoteCommand

$result = Invoke-Expression -command $command

Try this:

$csv = Import-Csv -Path "C:\IDRAC.csv"

$user = "root"

$pass = "Test@1234"

# ------------------------------------------

$cmds = @(

    "racadm config -g cfgUserAdmin -o cfgUserAdminPassword -i 2 Test@12345"

)

# ------------------------------------------

$csv | foreach {

$address = $_.IDRAC

# ------------------------------------------

    $plink_exe = "D:\plink.exe"

    $plink_option = "-ssh $address -l $user -pw $pass"

    $plink_cmd = ""

       $cmds | foreach {

           $plink_cmd += $_ + "`n"

        }

# ------------------------------------------

    $plink_run = "echo n | " + $plink_exe + " " + $plink_option + " " + """$plink_cmd"""

    $result = Invoke-Expression $plink_run

}

Some how I managed to work with this code., Only for few servers its showing error. But I can able to connect to that hosts using putty.

Any thoughts  to fix this error.

$CSVPath ='C:\IDRAC_187.csv'

$User = 'root'

$Pswd = 'test@123'

$plink = "D:\plink.exe"  # Plink Path

$plinkoptions = " -batch -pw $Pswd"

$cmd = @'

racadm config -g cfgUserAdmin -o cfgUserAdminPassword -i 2 test@1234

'@

$remoteCommand = '"' + $cmd + '"'

foreach($hst in Import-Csv -Path $CSVPath){

foreach ($hstpwdchange in $hst.IDRAC) {

$command =  "echo Y | "+ " " + $plink + " " + $plinkoptions + " " + $User + "@" + $hstpwdchange + " " + $remoteCommand

$result = Invoke-Expression -command $command

"" | select @{N="Executed On IDRAC";E={$hstpwdchange}},

    @{N="Result";E={$result}}

}

}

Success servers Output:
