First, prepare coastlines data from somewhere.

Option-A: get land_polygon from OpenStreetMap data ( http://openstreetmapdata.com/data/land-polygons ), simplify it, then place land_polygon.shp.

Option-B: pull coastlines.dat from DEFCON ( https://www.introversion.co.uk/defcon/ ) and place it into data/ directory.

Option-C: make it yourself and place it into data/ directory!

Option-D: touch data/coastlines.dat

Then,

$ make

And pray for succeed. Online required because Makefile includes fetching data from the Internet.

# ./ng <interfacename> [bpf]

or

$ ./ng <pcapfilename> [bpf]

ex.

$ XAUTHORITY=$HOME/.Xauthority sudo ./ng enp0s3 not tcp port 22

$ ./ng foo.pcap

Arrow key: navigate nodes

ESC: navigate to null

i: show/hide node informations

colon: activate command line (ESC cancels)

help helps you, but required to set loglines to enough. (it says how to do it.)

q or quit closes this application.

The autoexec file is executed at launch time.

Do source demoexec for getting fun instantly.

Note: no history function yet... hitting arrow key in command line does not perform any special things. It only navigate nodes.

Tab-delimited text file.

<longitude> <latitude> <population> <capital?> <iso3166_1_alpha_2> <countryname>
...

note for country fields: iso3166_1_alpha_2 is used for ipaddress-to-contry key, countryname is used just for display.

Text file consists from blocks of poly-lines.

poly-lines block is described as follows:

b
<longitude> <latitude>
<longitude> <latitude>
[<longitude> <latitude>]...

Tab-delimited text file.

<ipv4start> <numaddresses> <iso3166_1_alpha_2>
...

So, you must do manually fetch land_polygons(.shp) and convert using shp2dat.rb to load into this software, or use other "coast lines" data.
