151
Field Description
Type
Socket type:
• 1—SOCK_STREAM. This socket uses TCP to provide reliable
transmission of byte streams.
• 2—SOCK_DGRAM. This socket uses UDP to provide datagram
transmission.
• 3—SOCK_RAW. This socket allows an application to change the
next upper-layer protocol header.
• N/A—None of the above types.
Protocol Number of the protocol using the socket.
Connection info Source IP address and destination IP address.
