Ubuntu Server

This page is part of the Netband Project

OS version:

FreeNac(Incomplete)

  • Dynamic Virtual LAN management and assignment per end-device
  • LAN Access control (authentication, authorization)

MRTG

  • Network monitoring

1. Install the MRTG package 

$ sudo aptitude install mrtg

2. Create the initial config file and poll a device 

sudo cfgmaker  --output /home/mrtg/mrtg.cfg ciscodisco@10.0.0.21 [comunity@router/switch IP]

# Created by 
# /usr/bin/cfgmaker --output /home/mrtg/10.0.0.21.cfg ciscodisco@10.0.0.21 [comunity@router/switch IP]


### Global Config Options

#  for UNIX
# WorkDir: /home/http/mrtg

#  for Debian
WorkDir: /var/www/mrtg

#  or for NT
# WorkDir: c:\mrtgdata

### Global Defaults

#  to get bits instead of bytes and graphs growing to the right
# Options[_]: growright, bits, unknaszero

EnableIPv6: no

Include: /home/mrtg/10.0.0.21.cfg

For more information see cfgmaker

3. Either create additional cfg files for other devices, and copy/paste the relevant parts to the mrtg.cfg file or add them manually

4. Start MRTG 

$ sudo env LANG=C /usr/bin/mrtg /home/mrtg/mrtg.cfg

5. Make MRTG run every 5 minutes 

$sudo crontab  -e

#        m      h       dom     mon     dow     command
         */5      *       *       *       *       env LANG=C /usr/bin/mrtg /home/mrtg/mrtg.cfg  --logging /var/log/mrtg/mrtg.log
  • If snmpv3 is needed, install the net:snmp module
$aptitude install libnet-snmp-perl
  • If you want automatic index genereation with indexmaker
$sudo crontab  -e

#        m      h       dom     mon     dow     command
*/5      *       *       *       *       /usr/bin/indexmaker /home/mrtg/mrtg.cfg > /var/www/mrtg/index.html

Make apache run perl script

This will install the perl module in apache 

$ sudo aptitude install libapache2-mod-perl2

This addition in /etc/apache2/apache2.conf configuration file will allow cgi and perl script to be run in every directory, not just cgi-bin/. 

AddHandler cgi-script .cgi .pl

<Files ~ "\.pl$">
Options +ExecCGI
</Files>
<Files ~ "\.cgi$">
Options +ExecCGI
</Files>

Perl Scripts

If you want a index page to show all the mrtg graphs in one page create a new textfile and name it index.pl in your mrtg root folder. The indexfile should look like this 

#!/usr/bin/perl -w 
#############################################
# This script is created by Rasmus Elmholt  #
#############################################
use strict; 
use CGI::Carp qw(fatalsToBrowser); 

print "Content-type: text/html\n\n"; 

print '<?xml version="1.0" encoding="iso-8859-1"?>' , "\n"; 
print '<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.1//EN"' , "\n"; 
print '"http://www.w3.org/TR/xhtml11/DTD/xhtml11.dtd">' , "\n"; 
print '<html xmlns="http://www.w3.org/1999/xhtml" xml:lang="da">' , "\n"; 
print "<head><title>MRTG Network Monitoring</title></head><body>\n"; 


open(MRTGFILE, "/home/mrtg/mrtg.cfg");

while(my $line = <MRTGFILE>)
{
 if($line =~ /^Include:/)
 {
  $line =~ /^Include:\s(.*)/;
  open(MRTGFILE1, $1);
  #print "Found Include file";
  while(my $line1 = <MRTGFILE1>)
  {
   #print "line in Include: $line1<br>";
   if($line1 =~ /^PageTop/)
   {
    $line1 =~ /^PageTop\[(.*)\]:\s(.*)/;
    my $url = lc($1);
    print "<a href=\"$url.html\">$2</a><img src=\"$url-day.png\" /><img src=\"$url-week.png\" /><br /><br />";
   }
  }
 }
 if($line =~ /^PageTop/)
 {
  $line =~ /^PageTop\[(.*)\]:\s(.*)/;
  my $url = lc($1);
  print "<a href=\"$url.html\">$2</a><img src=\"$url-day.png\" /><img src=\"$url-week.png\" /><br /><br />";
 }
}
close(MRTGFILE);
 

print "</body></html>\n";

Remember to make it executable with chmod +x index.pl
