/localhost scope scenario

Topology: A-B. All are NDN nodes.

Incoming scope control

1. On host B, start NFD.
2. On host B, start ndn-traffic-server to serve ndn:/localhost/test-in.
3. On host A, start socat to create a relay from a listening UNIX socket to TCP hostB:6363.
   Write the path of this UNIX socket to $HOME/.ndn/client.conf.
4. On host A, invoke ndn-tlv-peek to request ndn:/localhost/test-in/A.
   Fail if Interest is answered.
5. On host B, stop ndn-traffic-server.
   Fail if total served Interest does not equal 0.
6. On host A, kill socat and restore $HOME/.ndn/client.conf.

Outgoing scope control

1. On host A, start netcat to listen on TCP port 6363.
   Redirect netcat output into a file.
2. On host B, invoke nfdc to create face tcp://hostA:6363.
   Fail if nfdc fails.
3. On host B, invoke nfdc to add nexthop for ndn:/ toward face created in step 8.
   Fail if nfdc fails.
4. On host B, invoke nfdc to add nexthop for ndn:/localhost/test-out toward face created in step 8.
   Do not fail if nfdc fails (forwarder MAY reject prefix registration that violates scope control).
5. On host B, invoke ndn-tlv-peek to request ndn:/localhost/test-out/B/c39b6fed4ce4464ea136062f80002c7c.
6. On host B, invoke ndn-tlv-peek to request ndn:/localhost/C/c39b6fed4ce4464ea136062f80002c7c.
7. On host B, invoke ndn-tlv-peek to request ndn:/ref-out/D/3b5fe3f184ff48adb3523180dee50555.
8. On host A, stop netcat.
   Search netcat output for string "c39b6fed4ce4464ea136062f80002c7c". Fail if this string exists.
   Search netcat output for string "3b5fe3f184ff48adb3523180dee50555". Fail if this string does not exist.
