well CRW is Congestion Window Reduced and ECN is Explicit Congestion
Notification in TCP/IP headers.

TCP inclused a 6 bit reserved field for future use as defined in RFC
793, 2 of those six reserved fields to be used for ECN purposes as
defined in RFC 3168.

8th bit= CWR (Congestion Window Reduced)
9th bit= ECE (ECN-Echo)

hope it helps... =)
 
references = RFC 793 and 3168.

--SNIP--
Jul 11 21:52:48 element kernel: (catch-all logging):: IN=eth0 OUT= MAC=*
SRC=80.97.2.93 DST=24.215.x.y LEN=60 TOS=0x00 PREC=0x00 TTL=34 ID=64252

        I got this for about 2 minutes, every 20 seconds or so, I just thought
it especially weird with "CWR ECE SYN", looking as to what the meaning
of this is.

        Any help is appreciated greatly,

                Adam
