The LN computer lives in the GRETINA net and doesn't know about the outside world.

• login on gateway machine nsclgw1.nscl.msu.edu
• login as gretina on a2.gam (35.8.35.163)
• login as ln on gln1 (10.0.4.11)

They are found in ~/scripts. The main LN program (gln_master) is a job run by root and not directly accessible by the user. Interactions happen via scripts. Most interesting is run-gln-ui.sh, the User Interface.

• run-gln-ui.sh: User Interface, 'help' gives option
• run-send-alarm.sh: Add your email here for receiving alarms
• run-log.sh: Add your email here for receiving logs
• run-log2.sh: Add your email here for receiving logs after each fill
• run-log3.sh:
• run-send-alarm-wd.sh
• finish_fill.sh: script executed after fill attempt
• run-gln-master.sh
• run-mail-que-view.sh
• run-time-sync.sh
• run-backup.sh
• run-tlog-and-plot.sh
• run-dlog-and-plot.sh
• run-mail-que-flush.sh
• run-view-master.sh: Output of the LN master process

The LN configuration file is found as ~/gln/gln.fig. It is self-explanatory. If this file got updated, use run-gln-ui.sh script and the command “load” in there. Note: After a “load” in the UI all detector fill schedules are gone! You need to do a “fill x y z after h:mm”.
