Looking for Log Analyzer

[-- Attachment #1: Type: text/plain, Size: 462 bytes --]

Before writing my own, I was wondering if there were tools available for
analyzing the output log file from iptables.  I was in particular looking
for tools which created a variety of different reports.  One such example
being a report listing the top traffic generators.

IPLIMIT Patch UDP

[Ing. CIP Alejandro Celi Mariategui]

(Sorry, but my english is very bad)

Hi,

I compile with p-o-m the server kernel with IPLIMIT Patch by Gerd Knorr
<kraxel@bytesex.org>

It work fine, i can limit ex: max 10 TCP connections on the server, but
i want to limit the UDP connections to 10 (max).

How I can do it?

This week I made a updlimit patch (shameless copy of iplimit ;-)
I will post it this afternoon/evening when I have more time (and
a cross post to the netfilter-devel list. Maybe they like it)

The IPLIMIT patch is limited to only work with TCP.  You'd likely need to 
write your own changes to the kernel.  At a VERY quick glance, this:

+	/* refuse anything but tcp */
+	if (ip->proto != IPPROTO_TCP)
+		return 0;

in the IPLIMIT patch (in iplimit.c) MIGHT provide the solution if it 
accomodated IPPROTO_UPD as well as, or instead of, IPPROTO_TCP.

I found http://iptablelog.sourceforge.net/.  I haven't gotten around to
installing it yet, but it looks ok from the screenshots.  It requires mySQL,
PHP and PERL with access to mySQL, so it's not a quick out-of-the-tar.gz
solution.
