[Nagiosplug-help] NRPE Problem

[Andrew]

I'm sorry, I didn't specify that. Yes I have. Here's some output lines:

 From the CentOS server with an NRPE daemon running:

CentOS-2:/usr/local/nagios/libexec# ./check_nrpe -H 10.1.5.10 -n -p  
5666 -c check_disk1
NRPE: Unable to read output
CentOS-2:/usr/local/nagios/libexec# ./check_nrpe -H 10.1.5.10 -n -c  
check_disk1
NRPE: Unable to read output
CentOS-2:/usr/local/nagios/libexec# ./check_nrpe -H 10.1.5.10 -n
NRPE v2.7

 From the CentOS server with the core Nagios processes running:

[root at CentOS-1 nagios]# /usr/bin/nagios -v /etc/nagios/nagios.cfg

Nagios 2.7

Things look okay - No serious problems were detected during the pre- 
flight check
[root at CentOS-1 nagios]#

[root at CentOS-1 nagios]# /usr/lib/nagios/plugins/check_nrpe -H

[root at CentOS-1 nagios]# /usr/lib/nagios/plugins/check_nrpe -H

NRPE v2.7

 From the RHEL4 server with NRPE running:

[root at RHEL4-1 nagios]# /usr/local/nagios/libexec/check_disk -w 20% -c  
10% -p /
DISK OK - free space: / 18231 MB (97% inode=97%);| /=457MB; 
15750;17719;0;19688
[root at RHEL4-1 nagios]# /usr/local/nagios/libexec/check_users -w 5 -c 10
USERS OK - 2 users currently logged in |users=2;5;10;0

I'm stumped. I don't see anything in any of the log files indicating  
what the output is nor what the problem is.

Any help is appreciated.

Thanks,

Andy
