Network script doesn't work. CentOS 2.6 - linux

Question

Centos 2.6.32-179.9.1.el6.i686
Hello, I have a problem with my noowbie script.
It does not work.
When I try to use it (for ex., /etc/init.d/myscript start) nothing happened.
Before that I make chkconfig --add myscript and chmod 777 on it.
Can you help me?
#!/bin/bash
#chkconfig: 2345 10 90
#description test
. /etc/init.d/functions
if [ ! -f /etc/sysconfig/network ]; then
exit 0
fi
. /etc/sysconfig/network
if [ -f /etc/sysconfig/network-scripts/ifcfg-eth1 ]; then
. /etc/sysconfig/network-scripts/ifcfg-eth1
fi
[ "${NETWORKING}"="no" ] && exit 0
[ -x -a /sbin/ifconfig ] || exit 1
case "$1" in
start)
echo "started"
ifconfig eth1 ${IPADDR} netmask ${NETMASK} up
echo 1 > /proc/sys/net/ipv4/ip_forward
;;
stop)
echo "stopping"
ifconfig eth1 ${IPADDR} netmask ${NETMASK} down
echo 0 > /proc/sys/net/ipv4/ip_forward
;;
status)
echo "showing status"
ifconfig
cat /proc/sys/net/ipv4/ip_forward

This line:
[ -x -a /sbin/ifconfig ] || exit 1
is a syntax error, and you should get a diagnostic from bash when you try to run the script. Assuming something in /etc/init.d/functions, /etc/sysconfig/network, or /etc/sysconfig/network-scripts/ifcfg-eth1 hasn't already caused your script to terminate, that line will.
And, actually, isn't /etc/sysconfig/network usually a directory? If so, this will cause your script to just exit, since it's not a file:
if [ ! -f /etc/sysconfig/network ]; then
exit 0
fi
Edit: You might want to change the first line of your script to #!/bin/bash -x to aid in debugging. That will show you a trace of what it's doing as it runs.
