14ea49401f3c8c61422aefbda43809e275f60c6cvboxsync# Test tcp:::state-change and tcp:::{send,receive} by connecting to
14ea49401f3c8c61422aefbda43809e275f60c6cvboxsync# the remote ssh service and sending a test message. This should result
14ea49401f3c8c61422aefbda43809e275f60c6cvboxsync# in a "Protocol mismatch" response and a close of the connection.
14ea49401f3c8c61422aefbda43809e275f60c6cvboxsync# A number of state transition events along with tcp send and receive
14ea49401f3c8c61422aefbda43809e275f60c6cvboxsync# events for the message should result.
14ea49401f3c8c61422aefbda43809e275f60c6cvboxsync# This may fail due to:
14ea49401f3c8c61422aefbda43809e275f60c6cvboxsync# 1. A change to the ip stack breaking expected probe behavior,
14ea49401f3c8c61422aefbda43809e275f60c6cvboxsync# which is the reason we are testing.
14ea49401f3c8c61422aefbda43809e275f60c6cvboxsync# 2. The lo0 interface missing or not up.
14ea49401f3c8c61422aefbda43809e275f60c6cvboxsync# 3. The remote ssh service is not online.
14ea49401f3c8c61422aefbda43809e275f60c6cvboxsync# 4. An unlikely race causes the unlocked global send/receive
14ea49401f3c8c61422aefbda43809e275f60c6cvboxsync# variables to be corrupted.
14ea49401f3c8c61422aefbda43809e275f60c6cvboxsync# This test performs a TCP connection to the ssh service (port 22) and
14ea49401f3c8c61422aefbda43809e275f60c6cvboxsync# checks that at least the following packet counts were traced:
14ea49401f3c8c61422aefbda43809e275f60c6cvboxsync# 4 x ip:::send (2 during the TCP handshake, the message, then a FIN)
14ea49401f3c8c61422aefbda43809e275f60c6cvboxsync# 4 x tcp:::send (2 during the TCP handshake, the messages, then a FIN)
14ea49401f3c8c61422aefbda43809e275f60c6cvboxsync# 3 x ip:::receive (1 during the TCP handshake, the response, then the FIN ACK)
14ea49401f3c8c61422aefbda43809e275f60c6cvboxsync# 3 x tcp:::receive (1 during the TCP handshake, the response, then the FIN ACK)
14ea49401f3c8c61422aefbda43809e275f60c6cvboxsync# For this test to work, we are assuming that the TCP handshake and
14ea49401f3c8c61422aefbda43809e275f60c6cvboxsync# TCP close will enter the IP code path and not use tcp fusion.
