I'm a sysadmin for Sentry Data Systems. I do linux and clustering and networking, and enjoy instigating a good STONITH deathmatch when I get bored.

Work-wise, I'm a giant fan of the k.I.s.s. principle - keep I.T. simple, stupid. Don't make things any more complex than the features you need.

In my spare time, I renovate houses and ride herd on a pack of dogs with extreme mental issues. My background and career are both in systems. I look at systems, analyze them, and use them or make them better. I likeCFO DIY home stuff because the systems are simple and it's rewarding to figure em out and use them. How do I know the things I do? I have probably been there, broken that, ruined the other thing, and had to figure out how to fix all of them. we have this saying in my group of friends-who-renovate-houses: "Ask me how I know."

comment Key differences between Nagios and Open NMS?
To be pedantic, Nagios does data collection for things like uptimes, it just doesn't persist the specific performance data passed back from the client nor does it output performance data. There are options to persist this data inside a Round Robin Database (RRD) in the Nagios configuration, and then Cacti (or just plain ol' RRDTool) can be used to output the data.

comment Open source DNS server with database backend
PowerDNS worked great when I was working in a very active pre-packaged virtual hosting environment. We used BIND as a secondary server. There was a cron job that checked the two for replication errors.

Allen, thanks -- that link did help. I've got a bunch of distro-specific stuff to debug now that I've followed the steps in that article, and I'll approve it if it ends up working.

comment Why does redhat seem to be so popular in the enterprise world?
Novell/SLES is gaining huge inroads. We're moving from a mishmash of BSD, Ubuntu, OpenSuSE and Redhat to SLES11 in a giant flock.

... I'm using Xen 3.3.1, YMMV with earlier versions.
