The same thing Wikipedia says, namely:
a trusted friend, counselor or teacher, usually a more experienced
person. Some professions have "mentoring programs" in which newcomers
are paired with more experienced people, who advise them and serve as
examples as they advance.
Joe, Randy and James are my mentors of 15, 5 and 5 years,
respectively, and all said the same thing, namely "nuke and repave, be
sure to be current on BIND" since it is a purpose-built box (ns1).
Since others have asked for details, they are below the sig.
With 20/20 hindsight, it is clear that I shouldn't have posted the
original post asking the list for help and hopefully informing other
potential targets of the risk (read: there were no responses to the
original post, therefore it was posted to the wrong audience).

There was no time for forensics at the time of the discovery; just
time to get advice and react.
What follows is from a few moments ago.
