I just found it and was able to cut a backup <em>script</em> of a system I inherited from 274 lines to only 165. (a mysqldump line for each database) :) Gracias! y saludos desde Puerto Rico :) Sonia, thank you for this.

]]> Comment on RFC 1178 and server naming by Sonia Hamilton http://www.snowfrog.net/2011/10/04/rfc-1178-and-server-naming/#comment-440 Sonia Hamilton Wed, 01 Feb 2012 01:57:12 +0000 http://soniahamilton.wordpress.com/?p=1194#comment-440 Hi Steve, I partly agree with you. VM's allow us to manage a swarm of single-purpose hosts, and then the naming matches up. But the example I gave of the host called <strong>chpvuat01</strong> that had been moved from <strong>uat</strong> to <strong>sit</strong> <em>was actually a VM</em>! VM's can become complex just like physical hosts, and their function can drift over the years. Also, the distinction between physical and virtual is arbitrary nowadays, because of P2V and V2P conversions. I still believe a better approach is to use synthetic names for all physical and virtual hosts, and use DNS CNAMES to track their function. Then as function drifts, additional CNAMES can be created. For example if there is a cluster of mail servers with CNAMES mail1, mail2, mail3, and an ldap server is added to mail3, mail3 could have an additional CNAME of ldap1.

We can now name machines by their functions - and even location, though it would need to be a virtual farm location - since we no longer repurpose we simply destroy and recreate. However I still hate overly long alphabet-soup names that mean nothing to most people, leak information to people who know the code, and are too easy to mistye or misread resulting in user error.
