Nagios Support Forum

Hello ,
in nagios server nrpe version is 3.2.1 , on remote linux host is 2.12 , as i checked i have to disable ssl in remote host but i do not know how can i do it please help me to modify it nrpe.cfg since as i checked in internet all procedure were recompilling not modifying nrpe.cfg
i did it in remote windows servers successfully but in our linux system i could not find syntax . i know i should pass -n -2 from nagios server but some parameter should be changed in remot host as well .

for windows i changed : use_ssl=0 , insecure=1 , verify mode = none but i do not know how can i define them in nrpe.cfg v2.12
nagios server (my icinga2):
/usr/lib/nagios/plugins/check_nrpe -H XXXX -n -2
CHECK_NRPE: Receive header underflow - only -1 bytes received (4 expected).

remote : Error: Could not complete SSL handshake. 1
nagios server (my icinga2):
