This is spewed to the console. Kernel 2.4.8, everything else works fine. Note that the device is localhost and the protocol is "qotd" according to /etc/services.
Why?

The protocol is udp according to /etc/protocols. qotd is not a protocol but a service. The device is the local loopback device. localhost is the hostname that this device is bound to. This seems to be an ipchains/iptables error. Some broadcast problem or something. Check your rules.

don't think its an iptables problem...its referring to the PRE_ROUTING hook..which is the first netfilter hook after a packet is accepted into the system...and before they are checked against any rule tables... sorry satya, dont think this'd would be of much help to you either..;-)

ok..after a little poking around,here'e some additional info - look at <path-to-ur-kernel-source>/net/core/netfilter.c Thats where this message is generated... are you running a dhcp client, by any chance? it could be the cause...try disabling its startup

Yes, that's it. I shut it off and started using a static IP.
But how do I use DHCP if I need to?

ok..there's no problem with your DHCP, this is just some debugging output. if you can , then recompile the kernel with config_debug turned off for netfilter
