Versions used on cable modem network

WHY

I need to upgrade the software version used on most of the modems so I first need to know what's out there. Here's what I did to find out

HOW

I'll get the version via snmp from the modems using this OID which should be available on most modems:

 .1.3.6.1.2.1.1.1.0 ( sysDescr.0 )

I'll use BRAA to get the info fast from all the network using this script.

Note: I have modems on 10.0.0.0/21, 10.10.0.0/21, 10.200.0.0/21, 10.210.0.0/21 so feel free to modify to suit your needs !

#!/bin/bash

for i in {0,10,200,210} ; do
        for j in `seq 0 9`; do
                echo "Doing 10.$i.$j.0-255 now"
                braa -d 50 public@10.$i.$j.0-10.$i.$j.255:161:.1.3.6.1.2.1.1.1.0
        done
done

After running the script redirecting the output to a file .. I run this script to identify the versions and model name ( I'm using php since it's easier to parse strings ):

#!/usr/local/bin/php -f
<?php

if(!isset($argv[1]) || empty($argv[1])){
        die("Usage is ".$argv[0]." input_file\n");
}
if(!is_file($argv[1])){
        die($argv[1]." isn't a file.");
}
$file = file_get_contents($argv[1]);
$file = explode("\n", $file);
foreach($file as $line){

Hope this helps you upgrade.
