Nagios check_smb and Windows Server 2008R2

We’re in the midst of upgrading our Windows Server 2003 servers to 2008R2. Three down, one to go. We noticed that the 2008R2 servers threw errors back to Nagios that the 2003 servers never exhibited. Lots of: CRITICAL SMB anon access: Domain=[CAE] OS=[Windows Server 2008 R2 Standard 7600] Server=[Windows Server 2008 R2 Standard 6.1] errors. […]

Stupid Puppet Trick: Identifying Groups of Hosts

My Ruby skills are practically non-existant, but I’ve managed to put together a relatively readable custom fact for identifying my Torque queues by a node’s hostname. Behold, HostgroupFact! Now I can factor out my hosts.equiv files back to a parent class, rather than duplicating the same file specifications on a per-queue basis. class cluster-host inherits […]

Client Configuration Management

Back at the infrastructures.org mothership, client configuration management is described as everything that makes a host unique and/or part of a particular group or domain. And for Unix-like systems, everything pretty much comes down to configuration files, services being enabled/disabled, and cron jobs. Hmm.
