"CHECK_NRPE: Error - Could not complete SSL handshake" error

[RIDS_I2MP]

Hi Team,

We are trying to monitor a Linux server, we have installed nrpe on it. I am receiving below error when I am executing the below command from nagios server:

Code: Select all

[nagios@hostname libexec]$ ./check_nrpe -H <remotehost IP> -p 5666
CHECK_NRPE: Error - Could not complete SSL handshake.
[nagios@hostname libexec]$ ./check_nrpe -H <remotehost IP> -p 5666 -c check_disk -a '-w 10% -c 15% -p /opt'
CHECK_NRPE: Error - Could not complete SSL handshake.

But the same command is executed successfully when executed locally on the remote host:

Code: Select all

[root@remotehost libexec]# ./check_disk -w 15% -c 10% -p /opt
DISK OK - free space: / 13772 MB (32% inode=97%);| /=28809MB;38131;40374;0;44860

We have made the nagios server IP entry in /etc/xinetd.d/nrpe file.

Kindly let us know the solution.

Did you restart the xinetd service?

If that doesn't help, please post the debug log from the remote system.
