works from command line fails from web

[Lois Bennett]

Alright I put it back to being run as nagios.  I had tried that
because our old server ran as root. and  I have a perl script I run on
the old one that is failing to connect to mysql when it is run as
nagios but that is a different problem I think.  As nagios both
check_dns and check_simap run successfully on the command line:

when I run as the nagios user from the command line this is what I get:

root #  su - nagios -c  "/opt/TWWfsw/nagiosserver30/libexec/check_dns
-H coffee.bwh.harvard.edu -s turing --timeout=25"
DNS ok - 0 seconds response time, Address(es) is/are 134.174.249.54

root #  su - nagios -c
"/opt/TWWfsw/nagiosserver30/libexec/check_simap -H turing -p 993"
SIMAP OK - 0.038 second response time on port 993 [* OK [CAPABILITY
IMAP4REV1 LITERAL+ SASL-IR LOGIN-REFERRALS AUTH=PLAIN AUTH=LOGIN]
turing IMAP4rev1 2006c.374 at Thu, 8 Jan 2009 14:26:56 -0500
(EST)]|time=0.038170s;;;0.000000;10.000000

In nagios on the web I get these errors.
	
DNS CRITICAL - '/usr/sbin/nslookup' output parsing exited with no address
IMAPS  Connection refused

The commands are :
define command{
	command_name	check_dns
	command_line	$USER1$/check_dns -H coffee.bwh.harvard.edu -s
$HOSTADDRESS$ --timeout=25
	}
define command{
        command_name    check_simap
        command_line    $USER1$/check_simap -H $HOSTADDRESS$ -p 993
        }

from resource.cfg:
 # Sets $USER1$ to be the path to the plugins
$USER1$=/opt/TWWfsw/nagiosserver30/libexec

The services:
#turing service template
define service{
	host_name			turing
	normal_check_interval		5
	retry_check_interval		1
	name				turing-service-template
	use				generic-service
        register                        0       		; DONT REGISTER THIS
DEFINITION - ITS NOT A REAL SERVICE, JUST A TEMPLATE!
	}

define service{
	use				turing-service-template
	service_description		DNS
	check_command			check_dns
	}

define service{
	use				turing-service-template
	service_description		IMAPS
	check_command			check_simap
	}

the versions of those plugins are

check_dns (nagios-plugins 1.3.1) 1.8.2.3
check_simap v1991 (nagios-plugins 1.4.12)

I downgraded check_dns from the old server because the new one
(check_dns v1992) kept dumping core.

Except for the mysql problem I have other services running fine.  ssh
and nrpe checking disk space and load and the presece of certain
processes on remote machines.

Where do I look now?

Thanks!
