I looked into Puppet and though I've got it managing parts of our infrastructure it seems quite difficult to bolt on to an existing setup.

Has anyone mentioned cluster ssh yet? Depending on your scale, cluster ssh and a "really big screen" may be a suitable way to manage N servers and do things like apply updates or make identical changes to all at once (or in groups). It also gives you the flexibility to apply commands to all or single out a system and do things just in the one window, then to back to talking to all. ---------------------------------------------------------------------- Jon Lewis, MCP :) | I route Senior Network Engineer | therefore you are Atlantic Net | _________ http://www.lewis.org/~jlewis/pgp for PGP public key_________
