Dear Sir, Thank you for your response, hope you don't mind me mailing you direct, only I am still not sure how to obtain the details you requested in order to progress. I am running Nagios on under Red Hat version 8. Here goes... As there is no config.status I will try and obtain one for this version of Nagios, but maybe this may be of help in the meantime. Below is a list of RPMs which I have used so far for this build. There is also an extract some of the errors obtained by running Nagios manually, as a foreground process. nagios-1.2-0.rh80.dag.i386.rpm nagios-plugins-1.3.1-1.9.i386.rpm nagios-plugins-extras-1.3.1-1.9.i386.rpm perl-Crypt-DES-2.03-2.dag.rh80.i386.rpm perl-Digest-HMAC-1.01-1.dag.rh80.noarch.rpm perl-Digest-SHA1-2.07-1.rh80.dag.i386.rpm perl-Net-SNMP-4.1.0-0.dag.rh80.noarch.rpm postgresql-libs-7.4.1-1PGDG.i386.rpm radiusclient-0.3.2-0.dag.rh80.i386.rpm <img src=cid:_1_090400003C90006AD88380256F56> Please note we are currently experincing problem with our incomming mail. ********************************************************************** This email and any files transmitted with it are confidential and intended solely for the use of the individual or entity to whom they are addressed.
