# Name:         cl_filenet_pe_etc_rc_dt_collector
#
# Description:  1. This script is used to have following entries
#		at the beginning of file /etc/rc.dt
#		
#		/usr/sbin/no -o tcp_sendspace=16384
#		/usr/sbin/no -o tcp_recvspace=16384
#		/usr/sbin/no -o tcp_keepidle=80
#		/usr/sbin/no -o tcp_keepintvl=20
#		/usr/sbin/no -o tcp_ephemeral_high=65535
#		/usr/sbin/no -o tcp_ephemeral_low=42767
#		/usr/sbin/no -o udp_ephemeral_high=65535
#		/usr/sbin/no -o udp_ephemeral_low=42767
#
#		Any missing entries will be automatically
#		updated. If /etc/rc.dt file doesn't exist
#		file will be created after updating above
#		entries.
#
#		2. Below mentioned commands would be excuted
#		
#		/usr/sbin/no -p -o tcp_sendspace=16384
#		/usr/sbin/no -p -o tcp_recvspace=16384
#		/usr/sbin/no -p -o tcp_keepidle=80
#		/usr/sbin/no -p -o tcp_keepintvl=20
#		/usr/sbin/no -p -o tcp_ephemeral_high=65535
#		/usr/sbin/no -p -o tcp_ephemeral_low=42767
#		/usr/sbin/no -p -o udp_ephemeral_high=65535
#		/usr/sbin/no -p -o udp_ephemeral_low=42767
#
#		With the execution of above commands, entries will
#		be made under "no" section in "/etc/tunables/nextboot"
#
#		At first availablity of entries would be verified using
#		"no" command, any missing entries will be updated
#		after executing above respective command.
#
# Arguments:    n/a

# Returns:      n/a
