There is some unexplained, non-stop traffic that won't go away. 27.50.2.191:80 keeps calling me at 63.192.15.229:4460. tcpdump shows 2 types of Flags: [S.] and [.], each one's packet numbers never change. Almost all of the packets are type 1. 1) 16:27:05.947510 IP 27.50.2.191.80 > 63.192.15.229.4460: Flags [S.], seq 777598812, ack 3826171711, win 65535, length 0 2) 16:27:06.100035 IP 27.50.2.191.80 > 63.192.15.229.4460: Flags [.], ack 1246380345, win 0, length 0 There is nothing listening at 63.192.15.229. Would any network gurus be willing to explain to me what may be going on or provide me insight? Something puzzling was that the source IP may be related to the DEBOGON Project? I know I can't stop incomers. Do I just put up with this until it a) gets fixed; b) goes away? Thanks
