Python Programming Language :: How to ping and shutdown a remote computer?


	How to ping and shutdown a remote computer? I am working on a Python script to perform as a remote computer manager. So far I have a WOL function working and I would like to add the ability to show if a machine is on or off (I figured I would do so by pinging the machine and seeing if I get a response). I would also like to add the ability to remotely shutdown a computer from the python script. Does anyone have a code snippet for pinging an IP, a code snippet for shutting down a remote Windows XP machine, and a code snippet for sending a HTTP request? Here is my current setup: - PC running python script - FreeNAS (media server running on FreeBSD. Can be shutdown from web interface so I planned on just sending that same web button click from the python script to shutdown the FreeNAS server) - Windows XP machine with folder share (What packet is sent over the network to remotely shutdown a Windows XP machine?) My hope is to have a script then when you start it will list all your remote computers/servers and show if they are currently on/off. Then you can select a server and turn it off if it is on or turn it on if it is off. Thank you in advance for any help provided. - John joj@gmail.com a crit : - Hide quoted text - > I am working on a Python script to perform as a remote computer > manager.

Requires Windows XP at the minimum. joj@gmail.com wrote: > Here is my current setup: > [...

First, I'd be quite worried if someone could send me a packet (maliciously or otherwise) which simply shut my machine down. Is this possible? Second, machines -- or networks -- may be configured to reject or swallow pings so the lack of a ping may not indicate vitality. Since you specify that the machine has a folder share, that means it's running SMB/NMB/whatever it's called across a few well-known ports, including 135 and 137-139 and 445. So you could attempt a socket connection to one of those: <code> import socket s = socket.socket () s.settimeout (0.25) try: s.connect (("192.168.100.84", 135)) except socket.error: print "not alive" else: print "alive" </code> To shut it down, someone has already suggested the shutdown command, although I think you'd have to specify the -m param to pass the remote machine name. Alternatively, you could use WMI (which inadvertently provides a means of determining vitality): http://timgolden.me.uk/python/wmi_cookbook.html#reboot_remote_machine (adapted a bit, but you get the idea) TJG
