netscanner-slave is a distributed multihreaded network scanner I wrote for a personal project some years ago.
It works as a cli program which is able to:
- Do on-call network scans to a given CIDR
- Work as a daemon which gets targets from a master node and reports scan results to it
I am not releasing the master's code, because I'm not its author. However, it shouldn't be very hard to write your own if you want to. Just look at webgate.[ch]
