Hi,

since yesterday i am seeing some nrpe errors on Xi machine about client, i tried to restart nrpe, verified nrpe.cfg all looks good. but still its not reporting properly.

Please see below errors from nagios Xi machine. i have same errors for 3 client machines.

Error: (use_ssl == true): Request packet version was invalid!
nrpe[21174]: Could not read request from client client_ip, bailing out...
nrpe[21174]: INFO: SSL Socket Shutdown.

Are you sure you pointed the NRPE to the right port on the XI machine? If NRPE tries to communicate over SSL, but it's to port 80, it will give those types of errors.

Can you connect to the XI server from the NRPE machine? You can test this by running:

Code: Select all

openssl s_client -connect [insert XI IP address here]:443 </dev/null |openssl x509

Please post the result of that here for further diagnosis.
