Huh? You'd better explain what you mean here a little further.
And yes, SYN is TCP.
You mean SYN is TCP *only*, not UDP.
You should read up on TCP/IP etc so that you understand protocols before posting to mailing lists. Kelly Robinson wrote:Looking at some suspicious behaviour in our logs... If someone sends a packet with the SYN bit set to a host, typically what is the client's source port? Or is that crafted too?
