7/11    Why does rlogin open two connections?  How does the server tell the
        client to listen and associate the "backwards" [S->C] connection with
        the initial connection [C->S]  ???
        C->S foo.978      bar.shell    49640      0 24820      0 ESTABLISHED
        S->C foo.977      bar.975      49640      0 24820      0 ESTABLISHED
        \_ One is the KVND listening in on your unencrypted connection.
           \- hello rlogin uses out of band signaling. read the rfc
              or one of the stevens book or UTSL or mail me if you think
              i might not dislike you. --psb
              \_ You think the KVND is limited by your puny and pathetic RFC?
                 For reasons of their own they've not yet pointed their orbital
                 mind control lasers in your direction, but oh, soon, very
                 soon now, my friend.
