Problem access with NSclient Agent
Posted: Mon Nov 15, 2021 8:17 am
Hi,
I have a problem with nsclient agent when I try to access the check_nrpe command returns:
My nsclient.ini has the next configuration:
in nsclient log in debug mode appear the next lines:
I try to execute check_nrpe command with the "-n" option but fails for timeout
Can you help me?
Thanks
I have a problem with nsclient agent when I try to access the check_nrpe command returns:
Reviewing the nsclient.log appears next message:./check_nrpe -H xxxx
CHECK_NRPE: Error - Could not connect to xxxx: Connection reset by peer
The access through telnet to port 5666 works correctly, but with the check_nrpe command not.Failed to establish secure connection: An existing connection was forcibly closed by the remote host: 1862
My nsclient.ini has the next configuration:
