Nagios + NRPE to Monitor Remote hosts failing


Hi there,

I need to perform characterization testing and I want to monitor two remote hosts CPU and Memory. I have installed Nagios on the monitoring machine. It is working fine. I installed the NRPE addon and I perform the command: /usr/local/nagios/libexec/check_nrpe -H 172.x.x.x

CHECK_NRPE: Error - Could not complete SSL handshake.

Remote host:
/usr/local/nagios/libexec/check_nrpe -H 172.x.x.x
NRPE v2.12

I verified that both boxes are running:

OpenSSL> version
OpenSSL 0.9.7a Feb 19 2003

Both machines are running:
Linux 2.6.9-42.7
Red Hat Enterprise Linux AS release 4
Firewall is Disabled on Both Servers



maybe that could help you:

also, you can do a “ldd check_nrpe” and “ldd nrpe” on the right machines to see if the librairies are correctly linked.

another thing: did you have a look at the remote host syslog file ? (assuming the “debug” option of your nrpe.cfg is set to 1). Is there something significant ?

In the end, if everything fails
=> … .php?12091

Hope this helps :slight_smile:
