The CMS Experiment at the LHC is establishing a global network of inter-connected "CMS Centres" for controls, operations and monitoring at CERN, Fermilab, DESY and a number of other sites in Asia, Europe, Russia, South America, and the USA. "ci2i" ("see eye to eye") is a generic Web tool, using Java and Tomcat, for managing: hundreds of displays screens in many locations; monitoring content and mappings to displays; CMS Centres' hardware configuration; user login rights and group accounts; screen snapshot services; and operations planning tools. ci2i enables CMS Centre users anywhere in the world to observe displays in other CMS Centres, notably CERN, and manage the content remotely if authorised. Distributed shifts are already happening. "CMS-TV" aggregates arbitrary (live) URLs into a cyclic program that can be watched full-screen in any Web browser. "TV channels" can be trivially created and configured with either specific expert content or for outreach displays in public places. All management is done from a simple Web interface with secure authentication. We describe the specific deployment at CERN to manage operations in the CMS Centre @ CERN (more than 850 active users and ever increasing) including the aspects of system administration (PXE aims kickstart, gdm auto-login, security, afs account and acl management, etc.).
