If Collectd ever fails to lookup its IP adress from its hostname, the service startup fails and thus the package install. On your machines create a simple script which exits with return code 101 and place it in /usr/sbin/policy-rc.d With that, any installation of a service makes post-install script to not start them up. This allows you post install customization before actually activating the service for real. man invoke-rc.d for further details. -- Unix _IS_ user friendly, it's just selective about who its friends are. ___ collectd mailing list collectd@verplant.org http://mailman.verplant.org/listinfo/collectd

[collectd] Debian, collectd hostname lookup
Hi all On Debian, at post-install, Collectd is fired up. If Collectd ever fails to lookup its IP adress from its hostname, the service startup fails and thus the package install. As I am going to deploy a consequent set of machines with CFEngine and its package bundle, I would like to perform pre install checks to be sure the conditions are fullfilled before I launch the package install. How to get the machine hostname to have exactly the same result as collectd? - hostname (without options?) - hostname --fqdn How to perform the lookup excactly as collectd would do it (/etc/hosts is included) ? - dig ? (with some parameters?) - nslookup ? (with some parameters?) If some test fail, I need to deploy the right fix and only when all is clear I will launch package installation. What is important to me is to to be able to script some check the closest way as collectd would. Thank you for you help. ___ collectd mailing list collectd@verplant.org http://mailman.verplant.org/listinfo/collectd
