I administer servers and networking equipment in a small to mid-size heterogeneous (but 99.44% *nix) environment. I've worked on projects ranging from NIS-to-LDAP migration for authentication, to the deployment of a 164-CPU Beowulf cluster, to writing an extension to a large OO-PHP application. I'm a generalist, but my favorite areas are LDAP (and authentication in general), database design and administration, and automation (a broad category that includes writing tools and code to glue services together). Here are my favorite tools.
