# Creating the /etc/init.d/localnet boot script

A new file `/etc/init.d/localnet` is created containing the following:

`cat > /etc/init.d/localnet << "EOF"`
#!/bin/sh
# Begin /etc/init.d/localnet
#
# Include the functions declared in the /etc/init.d/functions file
# and include the variables from the /etc/sysconfig/network file.
#
source /etc/init.d/functions
source /etc/sysconfig/network
case "$1" in
start)
echo -n "Bringing up the loopback interface..."
/sbin/ifconfig lo 127.0.0.1
evaluate_retval
echo -n "Setting up hostname..."
/bin/hostname $HOSTNAME
evaluate_retval
;;
stop)
echo -n "Bringing down the loopback interface..."
/sbin/ifconfig lo down
evaluate_retval
;;
restart)
$0 stop
sleep 1
$0 start
;;
*)
echo "Usage: $0: {start|stop|restart}"
exit 1
;;
esac
# End /etc/init.d/localnet
`EOF`

## Setting up permissions and symlink

The proper file permissions and the necessary symlink are set or created by running the following commands:

> `cd /etc/init.d &&`
> `chmod 754 localnet &&`
> `cd ../rcS.d &&`
> `ln -s ../init.d/localnet S100localnet`
