There are 22 Cobalt RAQ2 servers. They are named for letters of the Greek alphabet. They run from beta to psi.


They are currently being used only for display purposes. Jess Unger and Matt Green wrote scripts to display time (accurate to ten seconds) and weather on the LCD displays. RSS feeds are pending.

NOTE: When the Cobalts are rebooted you MUST kill the process paneld on each machine before text can be written to the screens. Currently there is a script (/root/python/killer.sh) that will kill paneld on all the Cobalts. Then you can use the other scripts to add a message of your choice. The command to put something on the screen of a Cobalt (when logged in to the respective machine) is $ putlcd [line 1] [line 2]

If you would like a message displayed on the Cobalts, contact Peter Godofsky to have it put up.
