check-host-alive returns /bin/ping -n -U -c 1 192.168.231.7

[Russ Hubbard]

Hello,
   Last night I encountered some check-host-alive commands that are 
returning some weird information. They return "/bin/ping -n -U -c 1 
192.168.231.7" as the output and mark the host as down.  I've gone 
through the list archives and mostly I found that this can be caused by 
/bin/ping not having permissions of 4755. I have checked this, here is 
the verification:

-rwsr-xr-x    1 root     root        28724 Sep 11  2003 /bin/ping

I am currently running Nagios 1.2. I have been running nagios for about 
a year and this is the first occurance of this problem I have had. I 
have had a few outages in that time and they all return the appropriate 
status information. Here is an example:

PING CRITICAL - Host Unreachable (172.21.35.28)

Here is my check-host-alive command from checkcommand.cfg:

# 'check-host-alive' command definition
define command{
        command_name    check-host-alive
        command_line    $USER1$/check_ping -H $HOSTADDRESS$ -w 
3000.0,80% -c 5000.0,100% -p 1
        }


Any help at all in fixing this problem would be great. 

Thanks,

Russ
