"The Worm Before Christmas"
                            by Clement C. Morris

            (a.k.a. David Bradley, Betty Cheng, Hal Render,
                        Greg Rogers, and Dan LaLiberte)

        Twas the night before finals, and all through the lab
        Not a student was sleeping, not even McNabb.
        Their projects were finished, completed with care
        In hopes that the grades would be easy (and fair).

        The students were wired with caffeine in their veins
        While visions of quals nearly drove them insane.
        With piles of books and a brand new highlighter,
        I had just settled down for another all nighter ---

        When out from our gateways arose such a clatter,
        I sprang from my desk to see what was the matter;
        Away to the console I flew like a flash,
        And logged in as root to fend off a crash.

        The windows displayed on my brand new Sun-3,
        Gave oodles of info --- some in 3-D.
        When, what to my burning red eyes should appear
        But dozens of "nobody" jobs.  Oh dear!

        With a blitzkrieg invasion, so virulent and firm,
        I knew in a moment, it was Morris's Worm!
        More rapid than eagles his processes came,
        And they forked and exec'ed and they copied by name:

        "Now Dasher!  Now Dancer!  Now, Prancer and Vixen!
        On Comet!  On Cupid!  On Donner and Blitzen!
        To the sites in .rhosts and host.equiv
        Now, dash away!  dash away!  dash away all!"

        And then in a twinkling, I heard on the phone,
        The complaints of the users.  (Thought I was alone!)
        "The load is too high!"  "I can't read my files!"
        "I can't send my mail over miles and miles!"

        I unplugged the net, and was turning around,
        When the worm-ridden system went down with a bound.
        I fretted.  I frittered.  I sweated.  I wept.
        Then finally I core dumped the worm in /tmp.

        It was smart and pervasive, a right jolly old stealth,
        And I laughed, when I saw it, in spite of myself.
        A look at the dump of that invasive thread
        Soon gave me to know we had nothing to dread.

        The next day was slow with no network connections,
        For we wanted no more of those pesky infections.
        But in spite of the news and the noise and the clatter,
        Soon all became normal, as if naught were the matter.

        Then later that month while all were away,
        A virus came calling and then went away.
        The system then told us, when we logged in one night:
        "Happy Christmas to all!  (You guys aren't so bright.)"

        [ Note:  The machines dasher.cs.uiuc.edu,
          dancer.cs.uiuc.ed, prancer.cs.uiuc.edu, etc. have
          been renamed deer1, deer2, deer3, etc. so as not
          to confuse the already burdened students who use
          those machines. We regret that this poem reflects
          the older naming scheme and hope it does not confuse
          the network adminstrator at your site.  -Ed.]
