- # Test {tcp,ip}:::{send,receive} of IPv4 TCP to a remote host.
- #
- # This may fail due to:
- #
- # 1. A change to the ip stack breaking expected probe behavior,
- # which is the reason we are testing.
- # 2. No physical network interface is plumbed and up.
- # 3. No other hosts on this subnet are reachable and listening on ssh.
- # 4. An unlikely race causes the unlocked global send/receive
- # variables to be corrupted.
- #
- # This test performs a TCP connection and checks that at least the
- # following packet counts were traced:
- #
- # 4 x ip:::send (2 during connection setup, 2 during connection teardown)
- # 4 x tcp:::send (2 during connection setup, 2 during connection teardown)
- # 5 x ip:::receive (1 during connection setup, the response, 1 window update,
- # 1 banner line, 2 during connection teardown)
- # 5 x tcp:::receive (1 during connection setup, the response, 1 window update,
- # 1 banner line, 2 during connection teardown)
