Here is what iv got
root@mpnagios:/usr/local/nagios/libexec# ./check_ping -H 172.16.1.251 -w 3000.0,80% -c 5000.0,100% -p 5
/bin/ping -n -U -w 30 -c 5 172.16.1.251
CRITICAL - Could not interpret output from ping command
root@mpnagios:/usr/local/nagios/libexec#
and in the command.cfg file i have this

Code: Select all

################################################################################
#
# SAMPLE HOST CHECK COMMANDS
#
################################################################################


# This command checks to see if a host is "alive" by pinging it
# The check must result in a 100% packet loss or 5 second (5000ms) round trip
# average time to produce a critical error.
# Note: Five ICMP echo packets are sent (determined by the '-p 5' argument)

# '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 5
        }

# 'check-host-alive 2' command definition
define command{
        command_name    check_icmp
        command_line    $USER1$/check_icmp -H $HOSTADDRESS$ -w $ARG1$ -c $ARG2$ -p 2
}
this is the cgi.cfg file

Code: Select all

# PING SYNTAX
# This option determines what syntax should be used when
# attempting to ping a host from the WAP interface (using
# the statuswml CGI.  You must include the full path to
# the ping binary, along with all required options.  The
# $HOSTADDRESS$ macro is substituted with the address of
# the host before the command is executed.
# Please note that the syntax for the ping binary is
# notorious for being different on virtually ever *NIX
# OS and distribution, so you may have to tweak this to
# work on your system.

This is what iv do now --- i comment this part, but no changes 
#ping_syntax=/bin/ping -n -U -c 5 $HOSTADDRESS$
This is the router.cfg file

Code: Select all

define service{
        use                     generic-service

Please show the output of:

Code: Select all

which ping
ls -l /bin/ping
ls -l /usr/local/nagios/libexec | grep ping
Also, what version of the nagios plugins did you install on this system?

Can you uncomment the ping_syntax line from cgi.cfg and restart nagios? Then try to re-schedule a check from the interface.

Also, if you call /bin/ping and pass your information manually in from the command line does it error out?

What do you get returned when running this manually:

Code: Select all

/bin/ping -n -U -c 5 172.16.1.251
And:

Code: Select all

/usr/local/nagios/libexec/check_ping -H 172.16.1.251
Can you send us a copy of your check_ping plugin?

check_ping is a binary file, so you won't be able to read it manually. I believe slansing was asking for you to attach a copy of that file and upload it.

Can you run the following command and show us the output?

Code: Select all

/usr/local/nagios/libexec/check_ping -H 172.16.1.251 -w 3000.0,80% -c 5000.0,100% -p 5
