Quellcode-Paket kernel-patch-ulog herunterladen:
This package contains a patch to the Linux kernel, which provides a Netlink method of logging packets (via the ULOG target) to a userspace daemon. This daemon is modular and very extensible, and plugins such as syslog emulation and logging to MySQL can and have been written.
This patch is only useful with the ulogd package, which is the userspace daemon which accepts and actually logs these packets.
ulog and ulogd work on all architectures - you also need the iptables package to control the rules to log packets. Sample ulog target - ulog and then drop all packets to port 6000: iptables -N ulogdrop iptables -A ulogdrop -j ULOG --ulog-nlgroup 32 --ulog-prefix "Dropping - X +packet" iptables -A ulogdrop -j DROP iptables -A INPUT -p tcp --dport 6000 -j ulogdrop
