In my dmesg I have a lot of message lines which all start with and have all the same content. Googling gave me discussions since 2004 but no real solution. The only info somewhere was that it is: Multicast DNS, if you don't need it, disable it edit your /etc/host.conf and set mdns off For the time being I have disabled mdns but would like to find some background information. Do I need Multicast? Why does this message creeps into Linux since 2004? Whatis SFW2? Something that drops does not sound good. What drops? Somebody with answers? One of the complete lines I find the dmesg full with is: [60253.528099] SFW2-INext-DROP-DEFLT IN=eth0 OUT= MAC=5e:61:19:e7:2a:36:00:25:86:cf:8d:ae:08:00 SRC=64.41.4.144 DST=192.168.1.101 LEN=54 TOS=0x00 PREC=0x00 TTL=113 ID=6668 PROTO=UDP SPT=27896 DPT=1620 LEN=34 -- Linux User 183145 using LXDE and KDE4 on a Pentium IV , powered by openSUSE 11.4 (i586) Kernel: 3.0.0-rc4-2-desktop LXDE WM & KDE Development Platform: 4.6.4 (4.6.4) 11:16am up 17:01, 3 users, load average: 0.46, 0.36, 0.82 -- To unsubscribe, e-mail: opensuse+unsubscribe@opensuse.org For additional commands, e-mail: opensuse+help@opensuse.org
