- # Test sctp:::state-change and sctp:::{send,receive} by connecting to
- # the remote http service.
- # A number of state transition events along with sctp send and receive
- # events for the message should result.
- #
- # This may fail due to:
- #
- # 1. A change to the ip stack breaking expected probe behavior,
- # which is the reason we are testing.
- # 2. The lo0 interface missing or not up.
- # 3. The remote ssh service is not online.
- # 4. An unlikely race causes the unlocked global send/receive
- # variables to be corrupted.
- #
- # This test performs a SCTP association to the http service (port 80) and
- # checks that at least the following packet counts were traced:
- #
- # 4 x ip:::send (2 during setup, 2 during teardown)
- # 4 x sctp:::send (2 during setup, 2 during teardown)
- # 3 x ip:::receive (2 during setup, 1 during teardown)
- # 3 x sctp:::receive (2 during setup, 1 during teardown)
