that's the wrong way of saying 'OK'; you want to say 'OK' if all went really
ok, else say 'NOK!' and perhaps bailout, ie something like:
...
$iptables -t mangle -P OUTPUT ACCEPT &&\
$iptables -t mangle -P INPUT ACCEPT &&\
$iptables -t mangle -P POSTROUTING ACCEPT &&\
echo "Policing .......................................... [ OK ]" || {
echo "Something broke in 'Policing'!"
exit 1
}
...
modprobe iptable_mangle &&\
modprobe iptable_nat &&\
echo "0" > /proc/sys/net/ipv4/ip_forward &&\
echo "Loading Modules ................................... [ OK ]" || {
echo "Something broke in 'Modules Loading'!"
exit 2
}
...
or set 'set -e' but then your script would just exit on 1st error without
telling too much.
