4 Save and exit the file.
5 Enter the following command to turn on the init script:
chkconfig --add bypass

"bypass.conf File Example" on page
bypass.conf File Example
export DEVICE_FILE=/dev/n22xx0
export MODULE_NAME=n22xx
# Mode can be either 0 or 1.
# Mode 0 operates the card with both ports disconnected until they recieve
# a heartbeat from either the kernel OR user space process. Should that timer
# expire, the card will enter Bypass mode, allowing traffic to flow beyond
# the device.
# Mode 1 operates the card with both ports connected. If it receives a
# heartbeat signal, THEN IT WILL GO INTO BYPASS.
#
# Use Mode 0 unless otherwise directed.
#
export MODE=0
# Which type of heartbeat? If it is KERNEL_HEARTBEAT then the kernel module
# will generate the heartbeat ticks. This will protect against kernel panics
# and server reboots but offer nothing in the way of application protection.
export KERNEL_HEARTBEAT=1
# How many seconds does the kernel wait before issuing another bypass
# heartbeat? This amount of downtime is possible during reboot or kernel
# panic.
export KERNEL_HEARTBEAT_SECONDS=10
