I'm seeing a lot of the following line in
Jun 21 14:36:15 my-server kernel: [416219.080061] iptables denied: IN=eth0 OUT= MAC=ff:ff:ff:ff:ff:ff:the-mac-address:08:00 SRC=0.0.0.0 DST=255.255.255.255 LEN=328 TOS=0x00 PREC=0x00 TTL=128 ID=10081 PROTO=UDP SPT=68 DPT=67 LEN=308
This seems to happen just about every minute. Is this just my server trying to broadcast something and my own iptables denying it from happening? If so, what kind of service might do such a thing, and should I allow it? I'm running Postgres 9.2.4 on Ubuntu 12.04.2, and basically no other services aside from the basic, pre-installed packages.
