66 .Fn tcp:::state-change
72 argument exposes the version-agnostic fields of the IP header, while the
80 .Fn tcp:::accept-established
81 probe fires when a remotely-initiated active TCP open succeeds.
83 arguments expose the headers associated with the final ACK of the three-way
86 .Fn tcp:::accept-refused
89 to the remote host in response to the SYN segment.
92 .Fn tcp:::connect-established ,
93 .Fn tcp:::connect-refused ,
95 .Fn tcp:::connect-request
98 probes, except that they correspond to locally-initiated TCP connections.
100 .Fn tcp:::connect-established
101 probe fires when the SYN-ACK segment of a three-way handshake is received from
102 the remote host and a final ACK is prepared for transmission.
103 This occurs immediately after the local connection state transitions from
104 SYN-SENT to ESTABLISHED.
105 The probe arguments describe the headers associated with the received SYN-ACK
108 .Fn tcp:::connect-refused
109 probe fires when the local host receives a RST segment in response to a SYN
110 segment, indicating that the remote host refused to open a connection.
114 .Fn tcp:::connect-request
116 three-way handshake.
122 probes fire when the host sends or receives a TCP packet, respectively.
127 probes fire only for packets sent by or to the local host; forwarded packets are
133 .Fn tcp:::state-change
134 probe fires upon local TCP connection state transitions.
137 Its last argument describes the from-state in the transition, and the to-state
139 .Dv args[3]->tcps_state .
143 probe fires when a TCP segment is sent or received by the host.
