Connection refused for nrpe on Ubuntu 14.04

[danoreilly]

I installed nagios-plugins 2.0.3 and nrpe 2.15 on Ubuntu 14.04. Everything went fine until I did the check_nrpe and it appears to fail with:

# /usr/local/nagios/libexec/check_nrpe -H localhost
connect to address ::1 port 5666: Connection refused
NRPE v2.15
#

However, doesn't the "NRPE v2.15" line indicate it worked?

My config file is:

# default: on
# description: NRPE (Nagios Remote Plugin Executor)
service nrpe
{
flags = REUSE
socket_type = stream
port = 5666
wait = no
user = nagios
group = nagios
server = /usr/local/nagios/bin/nrpe
server_args = -c /usr/local/nagios/etc/nrpe.cfg --inetd
log_on_failure += USERID
disable = no
only_from = 127.0.0.1 10.18.215.98
}

Found the issue: extra garbage in /etc/hosts. I pared it down to:

127.0.0.1 localhost
10.18.84.42 ubdepot.echostar.com ubdepot

and it worked.
