CHECK_FTP returns "Connection refused"

[Bret Goodfellow]

I set up a separate command as you said, but I took out the "echo", and
the command executed as expected with the response coming back as:

FTP OK - 0.0003 second response time on port 21 .......

Here are my config files:

Checkcommands.cfg
# 'check_ftp' command definition
define command{
	command_name	check_ftp
	command_line	$USER1$/check_ftp -H $HOSTADDRESS$
	}

Hosts.cfg
########################################################################
##############
# 'dev01' host definition
#
########################################################################
##############
define host{
	use			generic-host		; Name of host
template to use

	host_name		dev01
	alias			dev01
	address			10.8.24.170
	check_command		check-host-alive
	contact_groups		linux-admins
	max_check_attempts	10
	notification_interval	480
	notification_period	24x7
	notification_options	d,u,r
	}

Services.cfg
# Service definition: check_ftp 
define service{
	use				generic-service		; Name
of service template to use
	host_name			dev01
	service_description		ftp
	is_volatile			0
	check_period			24x7
	max_check_attempts		3
	normal_check_interval		5
	retry_check_interval		1
	contact_groups			linux-admins
	notification_interval		1440
	notification_period		24x7
	notification_options		w,u,c,r
	check_command			check_ftp
	}
 
Other services for dev01 work ok, it's just check_ftp that doesn't work.

Thanks in advance,

Bret

Always run plugin tests as the nagios user. Tests as any other user are
not valid.

Look at your host definition. The 'address' is most likely incorrect or
unresolve-able by the nagios user. Check to make sure that you're
testing the plugin in exactly the same way that it's run by nagios. You
can see what nagios is running by echoing your plugin command to a tmp
file like below. If you can't figure it out, please post the complete
host, service and command definitions.

define somecommand {
...
	command_line echo "$USER1$/check_ftp <other stuff here>" >>
/tmp/nagios-runs-me }
