You didn't get the issue.  I know very well how to call check_ping with
-4 - I can do that with my local config.  But check_ping -4 DOES NOT
call "ping -4" - it just calls "ping".  The -4 option does *NOTHING*. It
basically is the same as not passing "-6".

Also there is no package providing /etc/nagios-plugins/config/ping.cfg.
Maybe you meant /usr/share/monitoring-plugins/templates-basic/ping.cfg ?
But not really relevant at all.

cheers,
Stefan
