On my CentOS box that I use mainly as a web server, I have iptables
set to log and reject anything that I don't expect. So lately,
I have getting things like this:
Mar 29 17:27:20 mbrc20 kernel: IPT-DROP IN= OUT=lo SRC=192.168.9.20
DST=192.168.9.20 LEN=60 TOS=0x00 PREC=0x00 TTL=64 ID=46910 DF PROTO=TCP
SPT=56624 DPT=80 WINDOW=32792 RES=0x00 SYN URGP=0 OPT
(0204400C0402080A4A26F7A50000000001030307) UID=0
that on at least one occasion repeated for every few seconds for
more than three hours. The ephemeral source port keeps changing in an
irregular manner.
Any suggestions?
Thanks,
Mike
