Service Check Timed Out Error

[Kaplan, Andrew H.]

I ran the chsh command to change the nologin shell for the nagios user to
/bin/bash, and also provided a password for the nagios account. After that, 
I ran the check_nrpe command again from the command line, ie: manually, and was
able to get a response back from the nrpe client. 

Listed below are posts that were requested from a previous e-mail:

1. The output of "check_nrpe -H <nrpe_client> -c <remote_command>" run 
as the Nagios user:
		DISK OK [50534480 kb (99%) free on cosmos2:/database 

2. The Nagios command definition for your check_nrpe command:
# 'check_nrpe' command definition
define command{
	command_name	check_nrpe
	command_line	$USER1$/check_nrpe -H $HOSTADDRESS$ -t 60 -c $ARG1$

3. A Nagios service definition that uses the check_nrpe service on the 
relevant host:
command[check_disk1]=/usr/local/nagios/libexec/check_disk -w 20% -c 10% -p
/cosmos2/database

You won't be able to telnet back from the client to the server unless 
you're also running nrpe on the server.
As long as you can telnet server to client on that port, you're fine.

Also nrpe uses TCP only (I believe.)

Like David says, try su'ing to the Nagios user and running the command 
manually.

If all else fails, please post back the following:


2. The Nagios command definition for your check_nrpe command
3. A Nagios service definition that uses the check_nrpe service on the 
relevant host
