Hello, I'm trying to figure out how much packets are being forwarded on my OpenBSD firewall. Here a small script i wrote.
#!/bin/sh
VAL1=`netstat -s | grep 'packets forwarded' | head -1 | awk -F ' ' '{print $1}'`
sleep 1
VAL2=`netstat -s | grep 'packets forwarded' | head -1 | awk -F ' ' '{print $1}'`
echo "$(($VAL2-$VAL1))"
But i can not be sure if i am doing the right thing?
Can anyone check it please.
Thanks.
