    Hello, all.

    I found lots of port 0 traffic from various conuntry these days like this.

    [**] [1:524:5] BAD TRAFFIC tcp port 0 traffic [**]
    [Classification: Misc activity] [Priority: 3]
    04/27-05:55:01.306781 65.57.56.46:0 -> 211.1.x.x:6588
    TCP TTL:112 TOS:0x0 ID:464 IpLen:20 DgmLen:40 DF
    ******S* Seq: 0x95AF4 Ack: 0x0 Win: 0x200 TcpLen: 20

    is there any special way or tool to use port 0 in order to scan?

    and what's the meaning about this scan?

    [**] [116:55:1] (snort_decoder): Truncated Tcp Options [**]
    04/26-23:51:08.004547 211.230.86.34:0 -> 211.1.x.x:0
    TCP TTL:120 TOS:0x0 ID:38672 IpLen:20 DgmLen:48 DF
    ******S* Seq: 0xD563D9DB Ack: 0x0 Win: 0x4000 TcpLen: 28

    the source port and dest port is 0 alike.

    Thanks in advance.
