Brilliant Mark, thanks

Can you explain how this would have happened?

TBH the OS restore was from last Dedember-ish, when I first installed nagios, but I don't remember doing this step previously...

Thanks

B

Stop nagios and run 'make install-commandmode' from the original tarball you installed from or --

chmod 775 /usr/local/nagios/var/rw
chmod g+s /usr/local/nagios/var/rw
make sure that the user your web server runs as is a member of the nagcmd group

restart apache, restart nagios.

HTH
