rsm@math.arizona.edu:
   Several machines in the nrl.navy.mil domain have an interesting
   undocumented feature: if you finger them, they finger you right back! 
   Examples are tiger.nrl.navy.mil and ccf.nrl.navy.mil.

Now let me get this straight: I take a copy of Tiger's fingerd and I
install it on foo.bar.bletch.edu.  Logged into Foo, I finger
joe@tiger.nrl.navy.mil.  Watching my syslog in another window, I
observe an incoming finger request from Tiger.  This induces my
fingerd (being a copy of Tiger's) to perform "finger
@tiger.nrl.navy.mil" after which I observe another finger request
coming back from Tiger, to which my fingerd responds with "finger..."
