nrpe not working

[emily zhou]

Hi JC,
I guess you have experience with NRPE, could you give me some clue?
I use command line working fine:   (Both Server and Client are Solaris 8)
~libexec/check_nrpe <remote server name or address> -c check_disk1
DISK OK - [2724125 kB (52%) free on /dev/dsk/c0t3d0s7]

However, when I put in the nagios, it's not working, the status information is :
Incorrect command line arguments supplied, my config file this:

in checkcommands.cfg:
# 'check_nrpe' command definition
define command{
 command_name check_nrpe
 command_line $USER1$/check_nrpe -H $HOSTADDRESS$ -c $ARG1$
 }

In services.cfg:
define service{
        use                                   generic-service
        host_name                        netsrv
        service_description           File System / Check
        is_volatile                          0
        check_period                    24x7
        max_check_attempts          3
        normal_check_interval        5
        retry_check_interval           1
        contact_groups                  unix-admins
        notification_interval           120
        notification_period             24x7
        notification_options            c,r
        check_command               check_nrpe!check_disk1
        name                            remotefstemp
        }

In remote server's nrpe.cfg, the check_disk1 is defined, no doubt about that, as
the command line is working.
Any help would be appreciated.
Thanks,
Emily
