    List, wake and scan nodes in a network.

    Scantron looks pretty awesome! liwasc isn't using nmap internally, the entire network scanner part ( is <150 SLOC and the port scanner is <250 SLOC. Go has some really nice low-level networking APIs, especially when combined with `gopacket`.

    I haven't really tested it on anything larger than /28 - it should probably work on larger ones as well though (it limits the maximum concurrent port & network scans so that ulimit etc. aren't an issue) :)

  • scantron

    A distributed nmap / masscan scanning framework complete with scan scheduling, engine pooling, subsequent scan port diff-ing, and an API client for automation workflows.

    Glad to see more open source options (I develop and maintain Scantron when it comes to network scanning! Appreciate your contribution to the community.

    So you're not using nmap under the hood?

    What's the largest IP space you've tested it on so far?
