After an email failure (MS Exchange variety) I told my email client to stop pulling my inbox. After getting no spamassassin (or debian-user) emails in several days, I remembered that I didn't turn in back on. That's my excuse for not replying sooner. :-) I'm working on a sitewide spamassassin gateway server, and I'm now at the stage of gathering data for fine-tuning info. A histogram is one of those things. I've got a PHP imaging script which updates the histogram, and a web-frontend to change parameters. Check out http://gateway1.oc.edu/spam Here's my totally uncommented raw PHP script. You can get the frontend page by viewing the page source from the URL above. ---- BEGIN inline_image.php ----- <?php ############################################################################################# function syslog_to_unix_time ($syslog_string) { $months = array("Jan" => 1, "Feb" => 2, "Mar" => 3, "Apr" => 4, "May" => 5, "Jun" => 6, "Jul" => 7, "Aug" => 8, "Sep" => 9, "Oct" => 10, "Nov" => 11, "Dec" => 12); $syslog_array = split(" ",$syslog_string); $month = $months[$syslog_array[0]]; $day = $syslog_array[1]; $syslog_array = split(":",$syslog_array[2]); return mktime($syslog_array[0],$syslog_array[1],$syslog_array[2],$month,$day,date("Y")); } ############################################################################################ $width = !is_null($_GET['width']) ? $_GET['width'] : 700; $height = !is_null($_GET['height'])? $_GET['height']: 450; $high = !is_null($_GET['high']) ? $_GET['high'] : 15.0; $low = !is_null($_GET['low']) ? $_GET['low'] : 5.0; $step = !is_null($_GET['step']) ? $_GET['step'] : .5; $time = !is_null($_GET['time']) ? $_GET['time'] : "week"; $today = time(); switch ($time) { case 'day' : $evaltime = strtotime("-1 day"); break; case 'week' : $evaltime = strtotime("-7 days"); break; case 'month' : $evaltime = strtotime("-1 month"); break; default : $evaltime = strtotime("30 August 2002"); break; } include("/usr/lib/phplot/phplot.php"); $graph = new PHPlot($width,$height); $log_dir = opendir("/var/log"); system ("rm -rf /tmp/mailtest"); $greps = "| grep 'spamd' | grep '(' | grep -v 'running' | grep -v 'unknown' >> /tmp/mailtest"; while ($filename = readdir($log_dir)) { if (substr($filename,0,8) == "mail.log") { if (substr($filename,count($filename)-4,3) == ".gz") { system("zcat /var/log/$filename $greps"); } else { system("cat /var/log/$filename $greps"); } } } closedir($log_dir); $log = fopen("/tmp/mailtest", "r"); $curtime = array(); $timescores = array(); $valuesarr = array(); $timescores = file("/tmp/mailtest"); fclose($log); foreach ($timescores as $line) { if ($timescores = preg_split("/(\(|\))/",$line)) { $timescores[0] = substr($timescores[0],0,15); $curtime = syslog_to_unix_time($timescores[0]); if ($curtime >= $evaltime) { array_push($valuesarr,$timescores[1]); } } } sort($valuesarr,SORT_NUMERIC); $example_data = array(); foreach ($valuesarr as $num) { // is $num in $example_data? $num = $num * 10.0; while ($num % ($step*10) != 0) { $num--;} $num = $num / 10.0; $found = false; if ($num < $high && $num > $low) { for ($i = 0; $i < count($example_data); $i++) { if ($num == $example_data[$i][0]) { $example_data[$i][1]++; $found = true; } } if (!$found) { array_push($example_data,array($num,1)); } } } $graph->SetTitle("$which_title"); $graph->SetDataValues($example_data); $graph->SetIsInline("1"); $graph->SetFileFormat("$file_format"); $graph->SetBackgroundColor(array(200,200,200)); $graph->SetLabelColor(array(204,102,0)); $graph->data_color = array('maroon'); $graph->SetPlotType("bars"); $graph->SetXDataLabelAngle(90); $graph->SetPrecisionY(0); $graph->SetYLabel("Num of Emails"); $graph->SetXLabel("\nDegree of Spam"); $graph->DrawGraph(); ?> ---- END inline_image.php ------- Jeremy -- ************************************************************** Jeremy Turner, Help Desk Supervisor Phone: 405.425.5555 Email: [EMAIL PROTECTED] Phone: 405.425.1820 Information Technology Services, Oklahoma Christian University ************************************************************** Linux jturnermac 2.4.19 #10 Mon Oct 14 13:14:58 CDT 2002 ppc GNU/Linux 15:10:01 up 1 day, 1:40, 1 user, load average: 0.38, 0.15, 0.04 ------------------------------------------------------- This sf.net email is sponsored by:ThinkGeek Welcome to geek heaven. http://thinkgeek.com/sf _______________________________________________ Spamassassin-talk mailing list [EMAIL PROTECTED] https://lists.sourceforge.net/lists/listinfo/spamassassin-talk
