+"""Test various net timeouts.
+
+- Create three digibyted nodes:
+
+    no_verack_node - we never send a verack in response to their version
+    no_version_node - we never send a version (only a ping)
+    no_send_node - we never send any P2P message.
+
+- Start all three nodes
+- Wait 1 second
+- Assert that we're connected
+- Send a ping to no_verack_node and no_version_node
+- Wait 30 seconds
+- Assert that we're still connected
+- Send a ping to no_verack_node and no_version_node
+- Wait 31 seconds
+- Assert that we're no longer connected (timeout to receive version/verack is 60 seconds)
