MASSCAN-Cluster

Efficient clustering of MASSCAN results

Motivation

MASSCAN does a wonderful job at scanning the entire internet randomly.
I want to cluster the results by port, a feature that MASSCAN lacks.

Usage

Simply open your shell and write:

$ /path/to/masscan-cluster/msc.sh /path/to/output-dir

MASSCAN-Cluster will use $PWD/masscan.conf as the config file.
If you want to specify a different file, pass it:

$ /path/to/masscan-cluster/msc.sh /path/to/output-dir /path/to/masscan.conf

MASSCAN-Cluster rotates the files every 100kb, with is configurable via the environment variable MAX_FILESIZE_KB.
for instance, for 1mb chunks:

$ MAX_FILESIZE_KB=1024 /path/to/masscan-cluster/msc.sh

How does it work?

MASSCAN writes all its output to a file. MASSCAN-Cluster creates a named pipe for MASSCAN output-file,
runs MASSCAN, then clusters the output by port using the split script.
