Thanks for the help.I couldn't find any flags/fields in TCP packets indicated whether encrypted (as in the case of SSH packets). There isn't any, right?
Correct: there isn't anything like that in the TCP headers. Encryption
on TCP streams is an application level thing that only affects packet
payloads.
There are transport layer encryption protocols -- eg. IPSec, OpenVPN, etc.
-- but those allow tunnelling TCP streams through them and aren't necessarily
TCP themselves.
