PHP CURL script with CSRF support
-
I wanted to use a script I found to show my RRD graphs to the public. I found a nice PHP script, but it was pre2.0 so it didn't work.
CSRF was a royal pain to get working, but I managed.
I took this script here: http://captain-slow.dk/2010/09/24/public-rrd-graphs-from-pfsense/
graph_rrd.php
require_once("config.inc.php"); if (isset($_GET["file"]) && isset($_GET["interval"])) { //Get CSRF $ckfile = tempnam ("/tmp", "CURLCOOKIE"); $curl_handle = curl_init(); curl_setopt($curl_handle, CURLOPT_USERAGENT, "Mozilla/5.0 (Windows; U; Windows NT 5.1; en-US; rv:1.8.0.12) Gecko/20070508 Firefox/1.5.0.12"); curl_setopt($curl_handle, CURLOPT_SSL_VERIFYPEER, FALSE); curl_setopt($curl_handle, CURLOPT_SSL_VERIFYHOST, 2); curl_setopt ($curl_handle, CURLOPT_COOKIEJAR, $ckfile); curl_setopt ($curl_handle, CURLOPT_COOKIEFILE, $ckfile); curl_setopt($curl_handle, CURLOPT_FOLLOWLOCATION, 1); curl_setopt($curl_handle, CURLOPT_HEADER, 1); curl_setopt($curl_handle,CURLOPT_CONNECTTIMEOUT,2); curl_setopt($curl_handle,CURLOPT_RETURNTRANSFER,1); curl_setopt($curl_handle,CURLOPT_URL, $pfsenseprot .

Change the variables in here to match you config.
Don't forget to put in your default gateway name where it says [GATEWAY]
Easy way to set this is to goto the RRD quality page, and copy in image url for the graph.
You will find the .rrd line in the url.$username = "admin"; //username for pfSense $password = "password"; //password for pfSense $pfsenseip = "10.0.0.1"; //ip of pfSense $pfsenseprot = "http"; //http or https $refresh = 30; //Seconds between reload of the image $scale = array( 0 => array("14400", "4 Hours", 30), 1 => array("57600", "16 Hours", 30), 2 => array("172800", "2 Days", 180), 3 => array("2764800", "1 Month", 180), 4 => array("16588800", "6 Months", 180), 5 => array("33177600", "1 Year", 180) ); $graphs = array( 0 => array("wan-traffic.rrd", "WAN :: Traffic"), 1 => array("wan-packets.rrd", "WAN :: Packets"), 2 => array("[GATEWAY]-quality.rrd", "WAN :: Quality"), 3 => array("system-processor.rrd", "System :: Processor ") ); ?>index.php

Running 2.1.5-RELEASE (amd64)

$csrf = substr($buffer, strpos($buffer,'sid:') , 110);
Actually needs to be $csrf = substr($buffer, strpos($buffer,'sid:') , 55); in order to get the csrf token working.
This is because the token length is 55.
