Hi all,

Don't know if this is the appropriate place to ask so if not please just ignore.

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.

The [S.] is likely step 2 of the 3-way handshake in making a TCP connection. If you're not sending syns to 27.50.2.191:80, then perhaps someone else is, either as an attack against 27.50.2.191, or because they're using your IP space (likely on a private network) and have leaky NAT.

Something puzzling was that the source IP may be related to the DEBOGON Project?

Why do you think that?
