-Userspace logging facility for iptables / linux 2.4
-$Id: README,v 1.7 2002/04/16 12:44:41 laforge Exp $
-Project Homepage: http://www.gnumonks.org/projects/ulogd
-This is just a short README, pleaes see the more extensive documentation
-in the doc/ subdirectory.
-This packages is intended for passing packets from the kernel to userspace
-to do some logging there. It should work like that:
-- Register a target called ULOG with iptables
-- if the target is hit:
- - send the packet out using netlink multicast facility
- - return NF_CONTINUE immediately
-New with ipt_ULOG 0.8 we can accumulate packets in userspace and send
-them in small batches (1-50) to userspace. This reduces the amount of
-expensive context switches.
-More than one logging daemon may listen to the netlink multicast address.
-= Ulog library (libipulog.a)
-Just a little library like libipq.a which provides a convenient way to
-write userspace logging daemons. The functions provided are described
-in the source code, a small demo program (ulog_test) is also included.
-= ulogd daemon (ulogd)
-A sophisticated logging daemon which uses libipulog. The daemon provides
-an easy to use plugin interface to write additional packet interpreters and
-output targets. Example plugins (interpreter: ip, tcp, icmp output: simple
-logging to a file) are included.
-= documentation (doc)
-A quite verbose documentation of this package and it's configuration exists,
-please actually make use of it and read it :)
-The kernel part of the userspace logging facility (ipt_ULOG.o) is included
-in kernels >= 2.4.18-pre8. If you are running older kernel versions, you MUST
-install the ulog-patch from netfilter patch-o-matic FIRST !!
-Please go to the netfilter homepage (http://www.netfilter.org/)
-and download the latest iptables package. There is a system called
-patch-o-matic, which manages recent netfilter development, which has
-not been included in the stock kernel yet.
-Just apply the ulog-patch from patch-o-matic (there is some documentation
-included in the iptables package how to use patch-o-matic).
-Next you have to enable the kernel config option CONFIG_IP_NF_TARGET_ULOG in
-the netfilter subsection of the network options.
-Then recompile the kernel or just recompile the netfilter modules using 'make
-modules SUBDIRS=net/ipv4/netfilter'. Next step is installing the module using
-It is also a good idea to recompile and re-install the iptables package,
-if you don't already have libipt_ULOG.so in /usr/local/lib/iptables or
-Now You are ready to go. You may now insert logging rules to every chain.
-To see the full syntax, type 'iptables -j ULOG -h'
-At first a simple example, which passes every outgoing packet to the
-userspace logging, using netlink multicast group 3.
-iptables -A OUTPUT -j ULOG --ulog-nlgroup 3
-A more advanced one, passing all incoming tcp packets with destination
-port 80 to the userspace logging daemon listening on netlink multicast
-group 32. All packets get tagged with the ulog prefix "inp"
-iptables -A INPUT -j ULOG -p tcp --dport 80 --ulog-nlgroup 32 --ulog-prefix inp
-Since version 0.2, I added another parameter (--ulog-cprange).
-Using this parameter You are able to specify how much octets of the
-packet should be copied from the kernel to userspace.
-Setting --ulog-cprange to 0 does always copy the whole packet. Default is 0
