Accessing Windows actions(Shutdow.Restart)

Ruby
1

Hi All,

I want to access the windows functionalities such as Shut down, Restart,
Log off etc…

Please guide to me…

Because i tried win32OLE, Watir and few gems… But still there is no
improvement to access those things.

Awaiting reply.

One method is to run the command “shutdown.exe” with parameters:

system(‘shutdown.exe -r -f -t 0’)

To get a list of parameters, open a console window and enter

shutdown.exe /?

Here are a few ways. You’ll need admin privileges on any box you run
it against.

Using WMI via win32ole locally.

LogOff = 0
ForcedLogOff = 4
Shutdown = 1
ForcedShutdown = 5
Reboot = 2
ForcedReboot = 6
PowerOff = 8
ForcedPowerOff = 12

require ‘win32ole’

wmi = WIN32OLE.connect(“winmgmts:\\.\root\cimv2”)
list = wmi.execquery(“Select * from Win32_OperatingSystem”,nil,48)

list.each do |item|
item.win32Shutdown(LogOff)
end

Using ruby-wmi (gem install ruby-wmi) locally.

require ‘ruby-wmi’
#you’ll need the same constants as above

host = ‘computername’
os = WMI::Win32_OperatingSystem.find(:first)
os.win32shutdown(LogOff )

Using win32ole remotely.

require ‘win32ole’

constants

computer_name = ‘host’
wmi = WIN32OLE.connect(“winmgmts:\\#{computer_name}\root\cimv2”)
list = wmi.execquery(“Select * from Win32_OperatingSystem”,nil,48)

list.each do |item|
item.win32Shutdown(LogOff )
end

Using ruby-wmi remotely.

require ‘ruby-wmi’

constants

host = ‘computername’
os = WMI::Win32_OperatingSystem.find(:first, :host => host)
os.win32shutdown(LogOff )

Ok, you’ll need the ‘Shutdown’ privilege for a local machine and the
RemoteShutdown privilege for a remote machine.

LogOff = 0
ForcedLogOff = 4
Shutdown = 1
ForcedShutdown = 5
Reboot = 2
ForcedReboot = 6
PowerOff = 8
ForcedPowerOff = 12

require ‘rubygems’
require ‘ruby-wmi’

os = WMI::Win32_OperatingSystem.find( :first, :privileges =>
[WMI::Privilege::Shutdown] )
os.win32shutdown( Shutdown )

hope that helps,

Hi…
I tried your code and all OK!

Try this:

def myIpConfig
system(‘ipconfig’) // or puts system(‘ipconfig’)
end

myIpConfig // print your ip config

Use backticks:

a = ipconfig
=> “\r\nWindows IP Configuration\r\n\r\n\r\nEthernet adapter Wireless
Network Connection 2:\r\n\r\n Connection-specific DNS Suffix .
: \r\n IP Address. . . . . . . . . . . . : 192.168.1.101\r\n
Subnet Mask . . . . . .
. . . . . : 255.255.255.0\r\n Default Gateway . . . . . . . . .
: 192.168.1.1\r\n”
a
=> “\r\nWindows IP Configuration\r\n\r\n\r\nEthernet adapter Wireless
Network Connection 2:\r\n\r\n Connection-specific DNS Suffix .
: \r\n IP Address. . . . . . . . . . . . : 192.168.1.101\r\n
Subnet Mask . . . . . .
. . . . . : 255.255.255.0\r\n Default Gateway . . . . . . . . .
: 192.168.1.1\r\n”

Try with backtick operator:
a = ipconfig

If you want only IP Address, you can do something like this:
a = ipconfig.scan(/IP Address.+?: (.+)\r/).to_s

No no, it’s possible, i tried:
var = system(‘ipconfig’)
puts var
and all is fine.

try this:
var = “#{system(‘ipconfig’)}”
puts “#{var}”

I think it must work.

Hi All,

Previously i am used ‘ipconfig’ → It should be ipconfig

So All are eager to fix more issues from me… k let us see
