win2003k with nsclinet++ (remote host) and ubuntu 16 serv with nagios (monitoring host).

my nsclient.ini

allowed hosts =,::1,
password = 12345
; Undocumented section
allowed ciphers=ALL:!ADH:!LOW:!EXP:!MD5:@STRENGTH
verify mode = peer-cert
insecure = true
CheckExternalScripts = 1
CheckHelpers = 1
CheckEventLog = 1
CheckNSCP = 1
CheckDisk = 1
CheckSystem = 1
NRPEServer = 1

from host i made:

check_nrpe -H

i got:

**CHECK_NRPE: Error - Could not complete SSL handshake.**

also in nagios:

missing -l parameters 

nagios img

several times leloaded service (nagios and nsclient serv).. what should i do? i read other soulutions but they didnt help me.

  • What does the NSClient++ log say? I find "verify mode = peer-cert" dubious as you are using insecure and thus not certificates so enforcing validation of remote certificate wont work... – Michael Medin Sep 27 '16 at 18:13
