Dataset Flags
– S0: Connection attempt seen, no reply.
– S1: Connection established, not terminated.
– SF: Normal establishment and termination.
– REJ: Connection attempt rejected.
– S2: Connection established and close attempt by originator seen (but no
reply from responder).
– S3: Connection established and close attempt by responder seen (but no
reply from originator).
– RSTO: Connection established, originator aborted (sent a RST).
– RSTR: Established, responder aborted.
– RSTOS0: Originator sent a SYN followed by a RST, we never saw a SYN
ACK from the responder.
– RSTRH: Responder sent a SYN ACK followed by a RST, we never saw a
SYN from the (purported) originator.
– SH: Originator sent a SYN followed by a FIN, we never saw a SYN ACK
from the responder (hence the connection was “half” open).
– SHR: Responder sent a SYN ACK followed by a FIN, we never saw a SYN
from the originator.
– OTH: No SYN seen, just midstream traffic (a “partial connection” that was
not later closed).
