2.1 iptables

http://forums.cacti.net/about8091.html
download cacti templates. Da iptables als root ausgeführt werden muss, wird das script über sudo aufgerufen: /etc/sudoers 

#logging
Defaults syslog = local2
# User privilege specification
www-data    ALL = NOPASSWD: /usr/share/cacti/site/scripts/iptables.pl

Damit der syslog nicht damit unnötig 'beloggt' wird, loggen wir an log-facility local2 und damit in ein eigenes Logfile /etc/syslog.conf: 

...
*.*;auth,authpriv.none;mail.!*;daemon.!info;cron.!*;local2.none         -/var/log/syslog
...
local2.* /var/log/sudo.log
#!/usr/bin/perl
###
### This is a quick perl script to
### pull bandwidth usage from iptables chains
###
### If you use/optimize this script, please let me know.
### Brian Stanback : brian [at] stanback [dot] net
##
### Example iptables rule for web bandwidth usage:
### > iptables -N WWW
### > iptables -A WWW -j ACCEPT
### > iptables -A INPUT -p tcp -m tcp --dport 80 -j WWW
### > iptables -A OUTPUT -p tcp -m tcp --sport 80 -j WWW
###
### Run "iptables.pl WWW" as root to test, note that you can
### combine more than one protocol into a single chain.
###
### Sudo Configuration (/etc/sudoers)
### > www-data    ALL = NOPASSWD: /usr/share/cacti/scripts/iptables.pl
###
### The Input String should be set to "sudo <path_cacti>/scripts/iptables.pl <chain>"
### and you will need to setup an input field so that the <chain> argument can be passed.
###
### The data input type should be set to COUNTER
###
##
##
## modified by: Paul Campbell <forums@campbell-multimedia.co.uk>
## Now returns a seperate entry for each rule.  Output for a
## 3 rule chain might now be:
## rule1:123 rule2:456 rule3:789
#
if ($ARGV[0]) {
$chains = `/sbin/iptables --line-number -xnvL $ARGV[0]`;
@chains = split(/\n/, $chains);
shift(@chains);
shift(@chains);
foreach( @chains ) {
/(\d+)\W+[0-9]+\W+([0-9]+)\W+/;
print " rule$1:$2";
}
print "\n";
#$chains[2] =~ /[\W+]?[0-9]+\W+([0-9]+)\W+/;
