| Apparently his exported template is corrupt (mismatched hash values). wazoqaz needs to email his cacti database to the devs so they can take a look what is going on.

Does anyone know why this script would be DOSing my cable modem config page? The script will run fine for about a week, and stop working thanks to a dead admin page on the Motorola 5100. I can't even get to it using a web browser. The only solution is to power cycle the modem. Is anyone else having this problem and how often is the script running anyways?
Oh, the internet continues to work fine, by the way.

| Possibly buggy web software on the cable modem. Cacti fetching a webpage every 5 minutes probably has exposed some sort of memory leak, etc which kills the modem. I've experienced something similar with a ZyXEL router and using telnet.

Well, for now I'm using X-10 to powercycle the modem, but for some reason, the script isn't working within cacti. Executing it from the shell works fine though. | Code: | #!/usr/bin/perl
use warnings;
use strict;
use LWP::Simple;
my %data;
my %trash;
my @keys = qw(DownFreq DownSNR DownPower UpFreq UpPower);
my $content = LWP::Simple::get("http://192.168.100.1/signaldata.html");
if (defined $content) {}
else {
system("heyu foff A16");
sleep 5;
system("heyu fon A16");
die "couldn't get it";
}
$content =~ s/\ //g;
# regex in html source order
if ($content =~ /(<td>Frequency<\/td>)/gi) { $trash{a} = $1};
#if ($content =~ /<td>(-?\d+)\sHz\s*<\/td>/gi) { $data{DownFreq} = $1; }
{ $data{DownFreq} = 77; }
if ($content =~ /(<td>Signal To Noise Ratio<\/td>)/gi){ $trash{a} = $1};
if ($content =~ /<td>(-?\d+)\sdB\s*/gi) { $data{DownSNR} = $1; }
if ($content =~ /(<td>Power Level<\/td>)/gi) { $trash{a} = $1};
if ($content =~ /<td>(-?\d+)\sdB\s*/gi) { $data{DownPower} = $1; }
if ($content =~ /(<td>Frequency<\/td>)/gi) { $trash{a} = $1};
#if ($content =~ /<td>*(-?\d+)\sHz\s*<\/td>/gi) { $data{UpFreq} = $1; }
{ $data{UpFreq} = 50; }
if ($content =~ /(<td>Power Level<\/td>)/gi) { $trash{a} = $1};
if ($content =~ /<td>(-?\d+)\sdBmV\s*/gi) { $data{UpPower} = $1; }
for (@keys) {
print "$_:" . $data{$_} . " ";
}
print "\n";

I'm wondering if it could be timing out or something, it sits there for probably 15 seconds before it power cycles.

|
|
Here is my modem info for comcast on the East Coast:
Scientific Atlanta
Name WebSTAR DPX2100 Series Cable Modem
Cable Modem Serial Number 101737630
Cable Modem MAC Address 00:0a:73:60:d2:80
Hardware Version 1.1
Software Version 2.0.1r1131-0304 (dpx2100-v201r1131-0304a.p7b)
it is a Comcast branded rental unit so it is likely alot of people use it. I hacked the original posted script to pull out the Down Power, SNR and Up Power. You can use the original xml file to import and then change script name to this one.
This uses the authentication information that I got here:
http://www.dslreports.com/faq/7363
For the Scientific Atlantica modem from comcast. I poll the page:
http://192.168.100.1/DpxSystem.asp
to retrieve the info I need and parse out the html.

I modified the perl script and template for a Motorola SB5120 cable modem. The template was created in Cacti 0.8.7b.
The files are also available here

|
|
I can run the script manually, and it outputs the values in the proper format.
However, no graph (blank or otherwise) is created, even though it appears to be configured correctly. When I turn debugging on, I don't see any errors or warnings.
What do I need to do to troubleshoot this?

I've gone over all the files, scripts and templates.
I can't find an error anywhere.
I'm new to Cacti (I've used MRTG for years, and toyed with Zenoss). I managed to get a couple of other graphs that were not working fixed on my install (namely the HTTPresponse time script).
I'm ready to pull my hair out....
