Posted: Wed Oct 25, 2006 9:34 Post subject: DD-WRT Uptime in Signature Image

Hi Folks,

since I've been asked about my signature including the uptime from some dd-wrt nodes I am now publishing the striped down rubbish code I hacked in 20min just to give php-newbies a starting point.

The script is <40 lines, no comments and whatnot, check out php.net to get more information.
To use this script you need a php (gd enabled) capaple webserver that can reach the dd-wrt nodes and the info sites enabled.
Please replace AAA.BBB.CCC.DDD and EEE.FFF.GGG.HHH with the IPs of you devices, delete last two $wrt54g_data lines or add more if you have fewer/more devices you whish to monitor.

Code:

<?php
$wrt54g_data["S v1.1"] = file("http://AAA.BBB.CCC.DDD/");
$wrt54g_data_addi["S v1.1"] = " (First router)";
$wrt54g_data[" v5.0"] = file("http://EEE.FFF.GGG.HHH/");
$wrt54g_data_addi[" v5.0"] = " (WDS node)";

foreach ($wrt54g_data as $version => $data) {
foreach ($wrt54g_data[$version] as $zeile) {
if (eregi("share.about",$zeile)) {
$splitted = split('"',strip_tags($zeile));
$splitted = split('"',$splitted[1]);
$line = "WRT54G".$version.": ".$splitted[0];
};
if (eregi(" up ",$zeile)) {
$splitted = split(' up ',ereg_replace(" +"," ",strip_tags($zeile)));
$splitted = split(', load',$splitted[1]);
$line .= " up: ".$splitted[0].$wrt54g_data_addi[$version];
if (strlen($line) > $maxlen) $maxlen = strlen($line);
$output[] = $line;
};
};
};

$font = 2;
$width = ImageFontWidth($font) * $maxlen;
$height = (ImageFontHeight($font)+1) * sizeof($output);

$im = imagecreate ($width,$height);
$background_color = imagecolorallocate ($im, 0, 255, 255);
imagecolortransparent($im,$background_color);
$text_color = imagecolorallocate ($im, 0, 0, 0);//black text
foreach ($output as $zeile) {
imagestring ($im, $font, 0, $y, $zeile, $text_color);
$y = $y + ImageFontHeight($font) + 1;
};
header("Content-type: image/png");
imagepng ($im);
imagedestroy($im)
?>

I know that I left out the different colors and whatnot but thats something you can add yourself... This ist just to get a grip...
To add comments go to the firs line and add $output[] = "My deviced:"; for top info or somewhere near $font = 2; for bottom notes...

Hope someone will find this one usefull...

hello

i already hosted the php script you have on the forum
its hosted here http://moreins.hyperphp.com/dd-wrt-sig/
im having trouble getting the png image. my router has the infosite enabled and is visible from the outside (you can check it out here: http://andresm.dnsalias.com)
i would really appreciate if you can help me out with this. it would be awesome if i get it to work.
here is the code im using. it the same exact one that you posted on the forum.
i would really appreciate if you give me any clue of why its not working the php script...im sooo frustrated right now...

Code:

<?php
$wrt54g_data["S v1.1"] = file("http://andresm.dnsalias.com");
$wrt54g_data_addi["S v1.1"] = " (First router)";

foreach ($wrt54g_data as $version => $data) {
foreach ($wrt54g_data[$version] as $zeile) {
if (eregi("share.about",$zeile)) {
$splitted = split('"',strip_tags($zeile));
$splitted = split('"',$splitted[1]);
$line = "WRT54G".$version.": ".$splitted[0];
};
if (eregi(" up ",$zeile)) {
$splitted = split(' up ',ereg_replace(" +"," ",strip_tags($zeile)));
$splitted = split(', load',$splitted[1]);
$line .= " up: ".$splitted[0].$wrt54g_data_addi[$version];
if (strlen($line) > $maxlen) $maxlen = strlen($line);
$output[] = $line;
};
};
};

$font = 2;
$width = ImageFontWidth($font) * $maxlen;
$height = (ImageFontHeight($font)+1) * sizeof($output);

$im = imagecreate ($width,$height);
$background_color = imagecolorallocate ($im, 0, 255, 255);
imagecolortransparent($im,$background_color);
$text_color = imagecolorallocate ($im, 0, 0, 0);//black text
foreach ($output as $zeile) {
imagestring ($im, $font, 0, $y, $zeile, $text_color);
$y = $y + ImageFontHeight($font) + 1;
};
header("Content-type: image/png");
imagepng ($im);
imagedestroy($im)
?>

im having problems with this, one is i dont know what variables dd-wrt gives off, and theres something wrong with the code

Code:

$splitted = split(', load',$splitted[1]);

something is wrong there, the split is suppose to start a new line if it stretches too far as im guessing, that line never shows, also theres no memory variable, im wondering how to do it like this guy

he has a memory variable as well

split doesnt add a new line, split just splits up the line, so you can grab a "piece" of the line. To add a new line, you add it to output[] _________________ Linksys EA6500v2 \| 5GHz 1st Floor AP \| Advanced Tomato 1.28.0000 -2.9-131 K26ARM USB AIO-64K Netgear WNR2000v3 \| 2nd Floor AP \| DD-WRT v3.0-r27805 std Behind a Raspberry Pi Dual WAN router

Heres my code, dirty, but it works....kinda:

Code:

$maxlen = 40;

foreach ($wrt54g_data as $version => $data) {
foreach ($wrt54g_data[$version] as $zeile) {
if (eregi("share.about",$zeile)) {
$splitted = split('"',strip_tags($zeile));
$splitted = split('"',$splitted[1]);
$line = "Linksys WRT54G".$version.": Running ".$splitted[0];
};
if (eregi(" up ",$zeile)) {
$splitted = split(' up ',ereg_replace(" +"," ",strip_tags($zeile)));
$splitted = split(', load',$splitted[1]);
#$line2 = " Current uptime: ".$splitted[0].$wrt54g_data_addi[$version];
$line2 = " Current uptime: ".$splitted[0];
$line3 = " Current one minute load".$splitted[1];
$splitted = split(',',$line3,3);

};

$splitted = split('MemFree:\'\,\'',strip_tags($zeile));
$splitted = split('\'',$splitted[1]);
$line4 = " Total Memory: 30228kB, Total Free: ".$splitted[0]."kB";
$output[3] = $line4;
};
};
};

$font = 2;
$width = ImageFontWidth($font) * $maxlen;
$height = (ImageFontHeight($font)+1) * sizeof($output);

$im = imagecreate ($width,$height);
$background_color = imagecolorallocate ($im, 0, 0, 0);

jbarbieri, i have tried your code and works great.
the thing is that, in order to access the image, i need to type the php file. i was wondering on how can i access the image by going to the png or gif file.
in my ftp server, i created a folder called router. inside of it, there is only one file (sig.php). and i can access by typing this
http://moreins.x10hosting.com/router/sig.php

of course if i try to go
http://moreins.x10hosting.com/router/sig.png, i will get an error since theres not sig.png file.

i can see that your signature is a png file. so, how can i do that?

i hope you, or anyone else, can help me

thanx

I just renamed the php file to png....and added a .htaccess file in the directory:

Code:

Options +All
AddType application/x-httpd-php gif

Or for PNG:

Code:

Options +All
AddType application/x-httpd-php png

This tells apache to treat gif files as php files, so it executes...the only downside, any gif file in that directory will try to execute as php.....so make sure you dont have any others, or just put the gif/png file in a directory on its own.
