The thirty inch telescope is run by a series of computers all communicating via the program tserver. The computer armin (aka fast, leuschner) acts as the switching yard and directs the appropriate tx commands to the correct computer and port. The other computers connected to armin are: ircam (controls the infrared camera), zeos (controls the SETI photometer), and crystalize (controls the telescope and filter wheel).
Follow this script if you need to restart or reset the tserver. Also follow this script if you change which computers are communicating with armin.
Log into every machine that is connected (see list above) and run stopnet, including armin.
