CHECK_NRPE: Error - could not complete SSL handshake

Nagios Nagios Configuration support
1

So, when running check_nrpe command - I get this:

[nagios_user@nagios objects]$ /usr/local/nagios/libexec/check_nrpe -H "client's IP"
CHECK_NRPE: Error - Could not complete SSL handshake.

I’ve got the file /etc/xinetd.d/nrpe configured and other things. The only thing that works is when I comment out the line all:all on the hosts.deny

#
# hosts.deny    This file describes the names of the hosts which are
#               *not* allowed to use the local INET services, as decided
#               by the '/usr/sbin/tcpd' server.
#
# The portmap line is redundant, but it is left to remind you that
# the new secure portmap uses hosts.deny and hosts.allow.  In particular
# you should know that NFS uses portmap!
# all:all

Once commented out and try running the check_nrpe command, I get a good result

[nagios_user@nagios objects]$ /usr/local/nagios/libexec/check_nrpe -H "client's IP"
NRPE v2.12

I’ve tried modifying the hosts.allow and added the IP address of the nagios server:

# hosts.allow   This file describes the names of the hosts which are
#               allowed to use the local INET services, as decided
#               by the '/usr/sbin/tcpd' server.
#
nrpe: IP address of nagios server
sendmail: all

Any suggestions on how to allow the SSL handshake with commenting out the all:all on the hosts.deny file?

Thanks…
