Nagios Support Forum

Hi,

I am having an error on a Solaris 10 (x86) server with NRPE. First, I tried to install the solaris agent (solaris-nrpe-agent.tar.gz); the install works, but I get the following error in the logs when I try to start the agent: I then tried to install NRPE from source, again the install works fine and this time the NRPE agent starts, but I always get:
CHECK_NRPE: Error - Could not complete SSL handshake.
When I run the command: (I get the same error when I run the command from the Nagios server)

I had a look in the troubleshooting section of the NRPE document and have made sure that the allowed hosts section of /etc/nagios/nrpe.cfg contains 127.0.0.1. Here is the NRPE process that runs: And here is the config: I tried different versions of NRPE - 2.12, 2.14 and 2.15 but the SSL error is always the same. I even tried installing openssl from source and configuring NRPE against that, but still no luck.

Do you have any suggestions or has anybody else experienced the same issue?

Thanks,
Michael

Have you restarted the NRPE on the client after modifying the following line? Do you have check_nrpe installed on the Solaris box, so that you can test the check locally?

OK, I've resolved this issue - the resolution is to compile openssl for 32-bit (although the system architecture is 64-bit).

In case anybody else has the problem, you need to download openssl and configure with (assuming your system is x86): Then compile nrpe with (assuming you installed openssl in /usr/local/ssl): Then restart nrpe and it should work.

Thanks,

Brilliant. Thanks for posting the solution here for future peoples.
