You are correct, that is the same version on Cent, although I cannot say that I have ever seen this issue in Cent. Are you able to compile from source? I think you are going to find either compilation of 2.16 or modification of 2.15 and compilation of that is needed to correct this. I have cloned t...

Looks like the listen_queue_size options was added to 2.16 https://github.com/NagiosEnterprises/nrpe/commit/15fb2cffb3c97ce24e1a60efbbf88133add157f4 But the port for pkg for nrpe2 is only at 2.15 http://www.freshports.org/net-mgmt/nrpe/ Also seems to be the case with CentOS as well yum list install ...

And what i mean by hit and miss is... I had read that wrong ("..be hit, and miss over..."), this makes more sense. I'm still unclear why you're seeing the errors you are. If the system load is low, nrpe should be able to accept the connections fast enough to avoid a backlog. Increasing th...

What do you mean by "miss over if i get the result"? Do the check_nrpe checks timeout? Have you been able to test the check commands manually? Are you running NRPE with xinetd or as a standalone daemon? NRPE's listen queue size only matters when run as a daemon. The NRPE daemon is running...

I can't say I've seen this one before. Is this a current version of nrpe? Is it from ports or straight from source?

Hi guys, It seem i am hitting some limits in either FreeBSD or NRPE. I have about 10 commands configured in NRPE but when i set the server live in the nagios config it will be hit and miss over if i get the result. I have tracked the issue down the the client machine causing the issue and found the ...

Hi guys,
Thanks for all the suggestions.
I have managed to solve the issue.

It seems it was the nagios server itself. It was pull nrpe from our pkgrepo and it was compiled with without ssl and the CentOS yum package was.

Took a while but i got there.

Thanks guys

How did you install NRPE on the client (from source, repo)? Are you running NRPE as a "standalone" daemon or under xinetd? Run the following commands on the remote box and show us the output: ps axuw | grep nrpe netstat -at | grep nrpe grep allowed_hosts /path/to/the/nrpe.cfg Did you rest...

Hi all, I have been having issues trying to get NRPE working on CentOS-6.6 x64. I have a fresh installation of CentOS-6.6-Minimal and installed NRPE from EPEL. Whenever i try query it from my nagios server ./check_nrpe -H 192.168.56.10 i get Error: Could not complete SSL handshake. 1 in the /var/log...
