Problems creating service to monitor ftp service

I've installed Nagios 2.0b3 on a Suse Enterprise 9 (SLES9) server system
and am trying to configure it to monitor
the ftp service on an ftp server located on the LAN.
I'm using the 'check_ftp' plugin to monitor the service:
check_ftp -H ftp.example.com -j
but any problems with the ftp server on the SLES9 system
are being reported as "HOST down" messages instead of "Service down"
messages. I'm receiving email similar
to the following:
From: nagios at example.com
To: nagios-admin at example.com
Subject: Host DOWN alert for ftp.example.com!
***** Nagios *****
Notification Type: PROBLEM
Host: ftp.example.com
State: DOWN
Address: 10.0.0.216
Info: Connection refused
Date/Time: Thu Jun 23 10:22:56 EDT 2005
Nagios is configured to use two configuration files, nagios.cfg and
minimal.cfg. The appropriate sections of minimal.cfg
are included at the end of this mesage. How do I modify my nagios
configuration to recognize a down service instead of
a down host?
Thanks
My configuration is below:
define host{
use generic-host ; Name of host
template to use
host_name ftp.example.com
alias ftp
address IP-address-of-ftp.example.com
check_command check-ftpx
max_check_attempts 10
notification_interval 120
notification_period 24x7
notification_options d,r
contact_groups admins
}
define service{
use generic-service ; Name
of service template to use
host_name ftp.example.com
service_description ftp login
