28 # Test {tcp,ip}:::{send,receive} of IPv4 TCP to a remote host.
30 # This may fail due to:
32 # 1. A change to the ip stack breaking expected probe behavior,
33 # which is the reason we are testing.
34 # 2. No physical network interface is plumbed and up.
35 # 3. No other hosts on this subnet are reachable and listening on ssh.
36 # 4. An unlikely race causes the unlocked global send/receive
37 # variables to be corrupted.
39 # This test performs a TCP connection and checks that at least the
40 # following packet counts were traced:
42 # 4 x ip:::send (2 during connection setup, 2 during connection teardown)
43 # 4 x tcp:::send (2 during connection setup, 2 during connection teardown)
44 # 5 x ip:::receive (1 during connection setup, the response, 1 window update,
45 # 1 banner line, 2 during connection teardown)
46 # 5 x tcp:::receive (1 during connection setup, the response, 1 window update,
47 # 1 banner line, 2 during connection teardown)
