[svlug] how to ping a dead system

Marc -- You've come into this discussion a bit late. There are at least two
versions of ping around:

        one has the -c option; when that option is not used, ping
                waits forever (or some extremely large number of seconds)
                for a response.
        one does not support the -c option, but defaults to failing 
                after 10 seconds with no response; as best I can
                determine, this wait delay cannot be adjusted.

Other than testing, I (and the others who responded on this thread) came up
with no way to find out which version a particular system has.

BTW, my (Debian) systems ... at least the ones I checked ... have the second
variant described above.
