hi,
how about this...
#!/bin/bash
GW1 = 'ping -c2 xxx.xxx.xxx.xx1 | grep "packet" | cut -d"," -f3 | cut -d"
" -f2 ' 2>/dev/null
GW1 = 'ping -c2 xxx.xxx.xxx.xx2 | grep "packet" | cut -d"," -f3 | cut -d"
" -f2 ' 2>/dev/null
if [ "$GW1 = "0%" ] && [ $GW2 = "0%" ]; then
ip route flush blah. .. blah...
echo -en "All connections are OK, Resuming normal operation"
elif [ "$GW1 !="0%" ] && [ $GW2 = "0%" ]; then
ip route flush..... bleeeh, ,.......,
echo -en "GATEWAY 1 is down... Switching all route to GATEWAY 2!!!"
elif [ "$GW1 ="0%" ] && [ $GW2 != "0%" ]; then
ip route flush..... bloooh, ,.......,
echo -en "GATEWAY 2 is down... Switching all route to GATEWAY 1!!!"
else
echo -en "patay ang dalawang gateway or baka high latency lang, oopps"
fi
#----------end script
correct me if I am wrong, but this is how I analyzed your problem..
cheers...
