# Resource script for sending WinPopups using smbclient

# Description: sends WinPopups to a sysadmin's workstation
# whenever a takeover occurs.
#
# OCF parameters are as below:
# OCF_RESKEY_hostfile
#
# where "hostfile" is a file containing the IPs/Workstation names
# one by line to be sent WinPopups
