-t parameter to optimize the timeout in seconds.
-f parameter to log the memleak of vulnerable systems.
-n parameter to scan entire network.
-i parameter to scan from a list file. Useful if you already have targets.

Sample usage
To scan your local 192.168.1.0/24 network for heartbleed vulnerability (https/443) and save the leaks into a file:

python heartbleedscan.py -n 192.168.1.0/24 -f localscan.txt -r

To scan the same network against SMTP Over SSL/TLS and randomize the IP addresses

python heartbleedscan.py -n 192.168.1.0/24 -p 25 -s SMTP -r

If you already have a target list which you created by using nmap/zmap

python heartbleedscan.py -i targetlist.txt
