Or perhaps it could not locate the library during install. do you have any libssl.so file present? usually install the ssl devel package fixes alot of ssl type errors w/ nagios/nrpe. -- Mat W. - <A href="http://www.techadre.com/">http://www.techadre.com</A> <HR id=stopSpelling> Date: Mon, 15 Jun 2009 13:10:02 -0400 From: vittal.sharada@gmail.com To: nagios-users@lists.sourceforge.net Subject: [Nagios-users] Issue with NRPE Hi, On my monitoring server Nagios is monitoring 3 remote servers. NRPE check is working fine on 2 of them. NRPE was installed using debian packages here. On my 3rd server I have a mail server running Centos 4.5 . I installes NRPE using - nrpe-2.12-3.el4.i386.rpm. ( rpm -ivh nrpe-2.12-3.el4.i386.rpm ). I also had my nagios plugins which I moved to /usr/share/nagios/plugins/ [ nagios/ and nagios/plugins in /ush/share was manualy created by me ] The /etc/nagios/nrpe.cfg has been configured to allow monitoring server to access it. NRPE is running on the mail server - /usr/sbin/nrpe -c /etc/nagios/nrpe.cfg -d Now, On the monitoring server I see SSL handshake issue with NRPE. So, tried - /check_nrpe -n -H hostname Now I get error saying - CHECK_NRPE: Error receiving data from daemon On the mail servr itself I get this error : ./check_nrpe -H localhost ./check_nrpe: error while loading shared libraries: libssl.so.0.9.8: cannot open Should I install anything else on the mail server? thanks! <hr />Insert movie times and more without leaving Hotmail®. <a href='http://windowslive.com/Tutorial/Hotmail/QuickAdd?ocid=TXT_TAGLM_WL_HM_Tutorial_QuickAdd_062009' target='_new'>See how.</a></body> </html>
