A script to check ports of a long range of IPs

[tirengarfio]

Hi,

i want to create a script that will check the ports of a range of IPs.

I could write all the IPs, but i have thought there is maybe a way to write the rage instead of all the IPs.

Is that true?

Do you advice any language to write this kind of scripts?

If you are doing shell scripting then as far as I know.. I dont think there is anything developed in shell scripting specifically for defining IP range. However in this case I would like to suggest to use 'seq' command to specify the IP range for each mask from 0-255 like
seq 0 255
and then in for loop
for $i in $(seq 1 255) do
echo "1.1.1.$i"
echo "1.1.$i.1"
echo "1.$i.1.1"
echo "$i.1.1.1"
done


Good luck.
