Ubuntu Server
This page is part of the Netband Project
Contents
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
