| Post subject: | kern.log - unexpected entry |
hi all my linode has 2 interfaces, lo and eth0. i have firehol installed to help with iptables, so related log entries contain 'IN-world' and 'OUT-world' to describe incoming/outgoing connections to eth0, which is labelled in firehol config as 'world' so, in my kern.log i see lots of the following; Oct 26 14:58:15 <hostname> kernel: ''IN-world':'IN=eth0 OUT= MAC=<mac-address> SRC=192.168.0.2 DST=<ip-address> LEN=52 TOS=0x00 PREC=0x00 TTL=118 ID=21359 DF PROTO=TCP SPT=2177 DPT=80 WINDOW=32768 RES=0x00 ACK FIN URGP=0 where mac-address and ip-address are the mac and public ip for eth0 i do not have a vpn on the linode and i do not use 192.168.x.x on my lan. so how does a private address end up being logged from a public address? is it just the result of a bad/misconfigured router somehwre? or something else? many thanks nev EDIT: this is apparently normal for a linode operating normally! |
