resource.cfg user variable problem

[Michael Eck]

Greetings.
I'm using Nagios 1.1 on a Debian woody (stable) Linux box monitoring 
548 services on 132 hosts.

I'm trying to use $USERx$ variables for snmp community strings in my 
services.cfg file but having no luck.  My check returns status UNKNOWN 
- SNMP problem - No data received from host.  This seems like 
appropriate behavior for a wrong/missing community string.

I have my resource.cfg defined in nagios.cfg:
resource_file=/home/nagios/etc/resource.cfg

I have my community string defined in my resource.cfg:
$USER6$=mystring (with non-alpha-numeric characters)

And my service check command:

define service{
	use				uptime
	check_command	check_uptime!$USER6$
	host_name		faste_on_router
}

...as defined in checkcommands.cfg
# 'check_uptime' snmp check command definition
# $ARG1 = snmp-community-string
define command{
         command_name    check_uptime
         command_line    $USER1$/check_snmp -H $HOSTADDRESS$ -o 
system.sysUpTime.
0 -C $ARG1$
         }


If I run it from the command line replacing the $USER6$ variable with 
the actual community string it works.  I have two suspicions.  First - 
$USER2$-$USER5$ are not defined.  Does nagios care?  Second, the 
community string in question end with an exclamation point (!).  could 
this perhaps be fudging something in the check_command because nagios 
is seeing the ! as a delimiter?  This doesn't seem to be the case.  
After a little bit of playing around I set $USER4$=public in my 
resources.cfg file and changed the check_uptime command definition for 
those hosts that use 'public' as their ro community string.  The same 
check_uptime fails with that community string as a variable.  When I 
replace it with the actual text 'public' it works fine.

Has anybody else had luck using the resource.cfg file for community 
strings in check commands?
