Real Time Connections code base?

Beniamin · February 11, 2025, 2:40am

Hi Everyone.
Can someone point me to the code base for luci connections (as in how it fetches/pulls this data from conntrack)? I would like to export / use this data for a project (with similar format), I figured it uses conntrack, but I like how it gives you the proto/src/dest/transfer. Any help would be greatly appreciated.

I think I may have found it. Let me know if I'm wrong tho

github.com/openwrt/luci

modules/luci-mod-status/htdocs/luci-static/resources/view/status/connections.js

master

'use strict';
'require view';
'require poll';
'require request';
'require rpc';

var callLuciRealtimeStats = rpc.declare({
	object: 'luci',
	method: 'getRealtimeStats',
	params: [ 'mode', 'device' ],
	expect: { result: [] }
});

var callLuciConntrackList = rpc.declare({
	object: 'luci',
	method: 'getConntrackList',
	expect: { result: [] }
});

var callNetworkRrdnsLookup = rpc.declare({

And here it reads the details from the OS level:

          export function conntrack_list(callback) {
          	const etcpr = open('/etc/protocols');
          	const protos = {};
          
          	if (etcpr) {
          		for (let line = etcpr.read('line'); length(line); line = etcpr.read('line')) {
          			const m = match(line, /^([^# \t\n]+)\s+([0-9]+)\s+/);
          
          			if (m)
          				protos[m[2]] = m[1];
          		}
          
          		etcpr.close();
          	}
          
          	const nfct = open('/proc/net/nf_conntrack', 'r');
          	let connt;

          		for (let line = nfct.read('line'); length(line); line = nfct.read('line')) {
