Restarting Required Services on Windows

After the DHCP and TFTP services have been configured, and the NFS mapping file has been created, you must restart the NFS daemons, the Internet services daemon, the port-mapping daemon, and the DHCP server. In general, it is easier to use the Windows Services utility to do this; however, you might have to install xinetd and dhcpd using the cygrunsrv.exe command before you can start and stop them using this utility.

The cygrunsrv.exe Command

The cygrunsrv.exe command is installed with Cygwin, and manipulates Windows services from Cygwin. For additional information about the command’s options, use cygrunsrv.exe --help.

To run the script, open a Cygwin Bash shell and issue the following command from the directory containing the script, typically C:\Cygwin\bin. (You only need to use the --stop and --remove commands if the service was previously installed. Otherwise, you can run just the last command.)

Next, specify the Cygwin services that will be used. (Commands must be issued on one line, without the line breaks shown here.)

$ cygrunsrv.exe --stop "xinetd"
$ cygrunsrv.exe --remove "xinetd"
$ cygrunsrv.exe -I "xinetd" -d 'Cygwin xinetd' -f \
  'Cygwin xinetd service' -p /usr/sbin/xinetd -e \
  CYGWIN=ntsec -a "-filelog /var/log/xinetd.log"

$ cygrunsrv.exe --stop "dhcpd"
$ cygrunsrv.exe --remove "dhcpd"
$ cygrunsrv.exe -I "dhcpd" -d 'Cygwin dhcpd' -f \
  'Cygwin DHCP service' -p /usr/sbin/dhcpd -e \
  CYGWIN=ntsec -a "-f eth1"

Note that if your Windows system uses an Ethernet device other than eth1 to communicate with the target, you should substitute the appropriate network interface card. In this example, the option -a "-f eth1" in the last line restricts the server to using the NIC named eth1.

The Windows Services Utility

Choose Settings > Control Panel from the Start menu, open Administrative Tools and then open Services.

To start a service, select it from the list. Then either choose Action > Start, or right-click on the service and select Start from the context menu. Do this for each of the services.

$ ps -a | grep xinetd
