>Environment:
System: FreeBSD mippet.ci.com.au 7.0-STABLE FreeBSD 7.0-STABLE #2: Wed Mar 5 09:21:55 EST 2008 rpp at mippet.ci.com.au:/usr/obj/usr/src/sys/LOCAL i386
>Description:
	We need to specify a source address to the "ping" command called
	by the Nagios plugin "check_ping".
>How-To-Repeat:
>Fix:
	Included is a patch against "check_ping.c 1810 2007-10-25 20:43:04Z"
	that accepts a new option "-S src-addr" (or "--src-addr addr"); it
	no doubt needs improvement e.g. support in "configure" etc.
