Whether or not iptables is configured to drop the packets (on input or forward), these messages still appear. I understand 224.0.0.2 means "multicast router", but why does my kernel have to be so verbose about it? Is there a sensible way to turn off the messages without playing havoc with my syslogd configuration? Kernel 2.4.1 on a P166/MMX, compiled with gcc 2.95.2, based on a barely-recognisable RH 6.2 installation. The NIC which these packets come in on is a 3c509, which is not in promiscuous mode. -------------------------------------------------------------- from: Jonathan "Chromatix" Morton mail: chromi@cyberspace.org (not for attachments) big-mail: chromatix@penguinpowered.com uni-mail: j.d.morton@lancaster.ac.uk The key to knowledge is not to rely on people to teach you it.
