Further tests using gdb suggest the problem is a follows:
| #define PING6_COMMAND "/bin/ping6 -n -U -c %d %s"
| #define PING_COMMAND "/bin/ping -n -U -w %d -c %d %s"
[ nagios-plugins-1.4/config.h, generated by ./configure ]
Both strings are used as an sprintf pattern
| asprintf (&cmd, rawcmd, timeout_interval, max_packets,
addresses[i]);
( rawcmd is strdup'd from either strings )
[ plugins/check_ping.c:106 ]
which is fatal since max_packets is understood as (char *) if ping6 is
the command used.
The trivial fix: Adding "-w %d" in PING6_COMMAND as in PING_COMMAND
worked for me. The actual magic should reside in the configure script.
The current (and broken) output is:
| checking for ICMP ping syntax... /bin/ping -n -U -w %d -c %d %s
| checking for ICMPv6 ping syntax... /bin/ping6 -n -U -c %d %s
Quite depressing to see appearently nobody else uses IPv6 and discovered
this before :-|
