It is completely omitted in the original source package at
http://www.fping.com/download/fping-2.4b2_to-ipv6.tar.gz (which is what
I built check_icmp from), aside from a notice indicating that a
non-existant message must be included in every distribution of the source.
The Stanford license, available at
http://graphics.stanford.edu/software/license.html clearly states that
it applies to programs whose associated web pages include a link to that
very license. The fping homepage http://www.fping.com does not (I
imagine the student who wrote it graduated).
Strictly speaking, this puts the fping source-code in the public domain,
so we should be free to do whatever we want with it, with proper credits
where credits are due, ofcourse. It's clearly stated in the check_icmp
source-code that it's a hack based on fping, and if it seems proper I
can add it to the usage() output as well.
