These are the passing questions for Netreads W'15 term. You will
find those for S'14 (the former contents of this file) in passing-S14.txt

Submit your command line scripts and packet captures. Add screenshots
as needed. Please note that I will _not_ accept MS Word files (.doc, .docx),

0. Get yourself some kind of IPv6 connectivity. Hurricane Electric's
tunnelbroker.net would work best with a public routable IP or a NAT
box that supports protocol 41, otherwise a Miredo IPv6 tunnel should
work for you.

1. Ping the IPv6 address of test6.dartmouth.edu as described in the
   passing-S14.txt exercises 1 and 2. That way, I will have your
   name and the IP address you are working from.

2. Look at the IPv6 address that you get in the response for the DNS
   transaction ID of 9999 in (1). At that address, you will find a DNS
   server.  If you ask that DNS server for the address of
   a.ns.test6.dartmouth.edu, you should get the same as that of
   test6.dartmouth.edu, and gw.test6.dartmouth.edu should give you the
   router that you are reaching this IPv6 network through.

   Test these with dig(1), e.g.:
       "dig @<DNS_SERVER_IPv6_ADDR> aaaa a.ns.test6.dartmouth.edu"
       "dig @<DNS_SERVER_IPv6_ADDR> aaaa gw.test6.dartmouth.edu" 

3. Your next task will be to look up the IPv6 address of  awesome.test6.dartmouth.edu
   on the DNS server discovered in (2).

   This should be easy with "dig" as above---except there is a
   problem.  There is a firewall between you and that system that
   hates the word "awesome" and will drop _any incoming UDP or TCP
   packet_ that contains the word "awesome". So your normal DNS query will time out and fail.

   So you will need to do something special to that UDP request to go through.(*)

4. In (3), you get an IPv6 address of an HTTP server. On that server,
   there is a picture at the URL that looks like
        http://[HTTP_SERVER_IPv6_ADDRESS]/awesome/ . Get it.

   Again, it should be easy to do by just typing that address into
   your browser's URL bar (remember that [] around an IPv6 address are
   needed in Firefox; you can check that you can access the site by
   going to http://[HTTP_SERVER_IPv6_ADDRESS]/ -- you should see a blank page with
   "Nothing special here".) Except there's still that firewall that
   hates the word 'awesome' and drops any packet in which this word
   occurs.

   So you will need to do something special with your HTTP request.

    should give you some ideas---if your previous exercises didn't already.
