Post by michaelbpe » Wed Apr 08, 2015 12:13 pm

Apr 8 09:23:08 daemon warn kernel: __ratelimit: 59 callbacks suppressed
Apr 8 09:23:08 daemon warn kernel: eth3: received packet with own address as source address
Apr 8 09:23:09 daemon warn kernel: eth3: received packet with own address as source address
Apr 8 09:23:09 daemon warn kernel: eth3: received packet with own address as source address
Apr 8 09:23:10 daemon warn kernel: eth3: received packet with own address as source
