REQUIREMENTS FOR WINDOWS XP TO BE REMOTELY SHUTDOWN BY A LINUX SERVER:
- Disable Simple File Sharing. UNCHECK "Use simple file sharing" under My Computer > Tools > Folder Options > View.
- Check the Windows Firewall and make sure ICMP is enabled and File and Printer Sharing is enabled. Go to Control Panel > Security Center > Windows Firewall > Exceptions > CHECK "File and Printer Sharing". Also on the Advanced tab > ICMP Settings > CHECK "Allow incoming echo request".
- You must be able to successfully ping the IP address of the remote Windows XP computer you want to shutdown.
- The default Local Policy in Windows XP to force a remote shutdown is limited to members of the Administrator group. If you want to change this, use the Group Policy Editor (gpedit.msc) to change this Local Policy. Select Computer Configuration > Windows Settings > Security > Local Policies > User Rights Assignment > Force shutdown for a remote system and change the properties to include the user or group you want to have this authority.
REQUIREMENTS FOR THE LINUX SERVER TO REMOTELY SHUTDOWN WINDOWS XP COMPUTERS:
- Samba must be installed and working properly. In our subnet, the RHEL5 Samba Server is configured as a WINS server for our own separate workgroup.
- It is recommended that the DHCP server be setup to assign static IP addresses to the Windows XP computers. This makes control of the lab computers much easier.
- It is also recommended that BIND be setup with a zone file for the subnet to provide DNS resolution for the computers in the lab subnet.
- The following command will remotely shutdown a Windows XP computer under this scenario:
In this example x.x.x.x is the IP address of the remote Windows XP computer, username is a member of the Administrator group on the Windows XP machine, and password is the correct password associated with the username.net rpc SHUTDOWN -C "enter a comment to display at shutdown" -f -I x.x.x.x -U username%password
- Test your configuration. Samba is very good about letting you know if your command works correctly or if you have problems.
- Next create a script to shutdown the Windows XP machines. Use crontab to schedule when you want the remote machines shutdown.
