You can download a perlscript that stops webpages when their transfer limit(s) have been reached. Look here to see what I mean:

http://64.22.109.195/1/bw.html

It starts/stops my webpages depending on how much transfer I have left for the month. You're welcome to copy it.

P.S. Run the script as a cronjob. Instructions are inside the script. Running the cronjob less often than once an hour or so, makes you a considerate user.

[edit] PHP script to retrieve the bandwidth in a nicer way

Here's a little script I've wrote, to use from command line: (you'll need to have php client for that... install php-cli)

#!/usr/bin/php
<?php

function human ( $num ) {
  if ($num<1024) {
    $str = strval($num)." K";
  } elseif ($num<(1024*1024)) {
    $str = strval(intval(floor($num/1024)))." M";
  } else {
    $str = strval(intval(floor($num/(1024*1024))))." G";
  }
  return $str;
} 

function kb ( $bytes ) {
  $bytes /=1024;
  return $bytes;
}

exec("wget -q --output-document=/tmp/mybw.xml http://www.linode.com/members/info/?user=yourusername",$output);
$xml = simplexml_load_file('/tmp/mybw.xml');
$bwdata = $xml->bwdata;
$year = $bwdata->year;
$month = $bwdata->month;

// $bw_max = round ( GB( floatval( $xml->bwdata->max_avail ) ), 2 ) ;
$dl = round(kb(floatval($bwdata->rx_bytes)),2);
$ul = round(kb(floatval($bwdata->tx_bytes)),2);
$total = round(kb(floatval($bwdata->total_bytes)),2);
$limit = round(kb(floatval($bwdata->max_avail)),2);

$precentage = round($total/$limit*100,0)."%";

echo("MyBandWidth, version 0.1\n");
echo("\n");
echo("Month: $month/$year\n");
echo("Uploaded: ".human($ul)."\n");
echo("Downloaded: ".human($dl)."\n");
echo("Total use: ".human($total)." from ".human($limit)." allowed ($precentage)\n");
echo("\n");

?>

In my system it's in /usr/bin/mybw, but it doesn't have to be, as long as it is executable.

Now - just type wherever you are mybw (if it's in /usr/bin or so) or run it with php command, and evuala.

Hope it helps... post questions in my talk page. Peleg 19:51, 30 May 2008 (EDT)
