   So... remember the previously posted comment that
most router melt downs are from human error ?

  Prophetic, isn't it ?

 It is sort of like when the Newbie unix Engineer comes up
and says "I can't get -so and so- application to work right"...

 And your aged -nix Guru, without even looking up, says "It is probably
a permissions error"..... and he is right.

  The true artform of the craft, is to realize that the maintenance,
and day to day operations of complex computer systems -isn't- a battle against
logic and math, like we were originally taught....

  But, in sooth, is a battle against human error,
in all its myriad of forms.
