I've been puttering away at improving my connmapperl port(s) of connmap (c/X11) geoip map network visualizer in terms of both features and performance. ip2asn.pl for the fully-offline(local) asn and org-name and peering look-ups is ever so slightly faster. The sql database side for long term detailed connection history is about 10x faster and 100x less IO which shows how bad it was before stateful connection tracking. Fancy things like sql queries and a mapping of the points onto the ipv4 range on a space filling hilbert curve (like the xkcd comic) also exist. The client program is forwards and backwards compatible; it just handles sudden socket closings a bit better, re: reconnecting now.
The new versions are all GUI server and headless client based using port 6789. To view their source: connmapperl-server-gtk2.pl, connmapperl-server-gtk3.pl and connmapperl-client.pl (and connmapperl2rc). To run the program(s) w/dbs: connmapperl-server-client-and-utils.zip (79MB)
The size is from the included geoip dbs and regional internet registry whois dumps. Leave the .pl files in the extracted folder and just run them there.
All this started with and was forked and ported from an inspiringly simple .c program for X11 called connmap. My versions just happens to be in another language and graphical toolkit and tacks on sql points history and a lot of not necessarily useful features and eye candy. I still don't understand the original connmap's math for the lat/lon gps to x/y pixel translation but luckily through open source licensing I can build with it.
