Thanks, i think its well done, but i couldn't get it to work.
I have refreshed the mrtg page but doesn't seem to have the lines.
See http://mojito.purplecards.com/mrtg
http://mojito.purplecards.com/ipfwmrtg.php (you told me to create)
# cat mrtg.cfg | grep [EMAIL PROTECTED]
# ipfw -at list 00002 0 0 count tcp from me 25 to any 00003 0 0 count tcp from any to me 25 00004 0 0 count tcp from me 110 to any 00005 0 0 count tcp from any to me 110 00006 0 0 count tcp from me 80 to any 00007 0 0 count tcp from any to me 80 00008 0 0 count udp from me 53 to any 00009 0 0 count udp from any to me 53 65535 138410 17490211 Fri Oct 29 17:44:31 2004 allow ip from any to any
I have php.4.39 installed, please advise, thanks.

I'm sure theres something better out there.. but heres a little script
I threw togethor a long long long time ago for use on my webservers..
I know its nasty and could easily be done in a better language but i'm
lazy as hell.. anyway it assumes you have ipfw support enabled and the
command line version of php installed.
/******************* start ipfwmrtg.php *********/
#!/usr/local/bin/php
<?php
$ipfw_out = shell_exec("ipfw show ".$_SERVER['argv'][1]."
".$_SERVER['argv'][2]);
$regexp = "/([\d]+)[\s]+([\d]+)[\s]+([\d]+)[\s]+.+/";
$ipfw = split("\n", $ipfw_out);
foreach($ipfw as $pp) {
       preg_match($regexp, $pp, $out);
       $tmp[] = $out[3];
}
//print_r($tmp);
//echo "fdc-bw 1 $tmp[1] $tmp[0] 0 0";
echo $tmp[1]."\n";
echo $tmp[0]."\n";
echo "1"."\n";
echo "name"."\n";
/************** end ipfwmrtg.php ***************/
/////////////////// code that goes in your mrtg.cfg
Title[smtp]: smtp total stats
Target[smtp]: `/usr/local/etc/mrtg/ipfwmrtg.php 2 3`
MaxBytes[smtp]: 15000000
PageTop[smtp]: <h1>smtp</h1>
Title[pop3]: pop3 total stats
Target[pop3]: `/usr/local/etc/mrtg/ipfwmrtg.php 4 5`
MaxBytes[pop3]: 15000000
PageTop[pop3]: <h1>pop3</h1>
Title[http]: http total stats
Target[http]: `/usr/local/etc/mrtg/ipfwmrtg.php 6 7`
MaxBytes[http]: 15000000
PageTop[http]: <h1>http</h1>
Title[dns]: dns total stats
Target[dns]: `/usr/local/etc/mrtg/ipfwmrtg.php 8 9`
MaxBytes[dns]: 15000000
PageTop[dns]: <h1>dns</h1>
////////////////// end code for mrtg.cfg
so anyway now that you have the code you'll need to add a couple ipfw rules..
something like
ipfw add 2 count tcp from me 25 to any
ipfw add 3 count tcp from any to me 25
ipfw add 4 count tcp from me 110 to any
ipfw add 5 count tcp from any to me 110
ipfw add 6 count tcp from me 80 to any
ipfw add 7 count tcp from any to me 80
ipfw add 8 count udp from me 53 to any
ipfw add 9 count udp from any to me 53
would count all traffic going out of your server on port 25 and the
second line would count all inbound traffic to your server on port
25..
You can add as many rules as you'd like just change the numbers for
each new rule.. You will also need to update the #'s for the new rules
in the Target[]: line that goes into mrtg.conf
Okay Well i'm not good at explaining things.. I hope this can help
you. good luck

Hi,
Is there anyway for us to trace the server bandwidth based on
specific ports on a MRTG graph?
Such as smtp bandwidth? port 25
pop3 bandwidth? port 110
web bandwidth? port 80
dns bandwidth? port 53
Is there any program or can MRTG do, please advise, thanks.
