Hi,
I am trying to write a script to check if ipforwarding is running on my access
box but I can't work out how to check for an integer in a script. It may be
clearer what I am trying to do for the bit of the script:
#Check if ipfwadm is on
IPFORW = `cat /proc/sys/net/ipv4/ip_forward`
if [ IPFORW == 0 ]; then
echo "ipforwarding is OFF"
exit 0
fi
I have tried stuff like using 'let' and putting brackets round the expression
but just can't get it right. I clearly am not getting what the O'Reilly book
is trying to tell me about numerical values. Can anyone help please?
Thanks,
Steve
