MCenter Control Room (MC-CR) x3726 or x8871

* Call the Main Control Room at the start and at the end of shift. This is required, and pleasant.

* If the beam goes away for more than a few spills, look for Accelerator Alarms in ACNET (a default window). If the problem persists a few minutes, and you see nothing about it in the MCR elog, (or you just really want to find out more), call the MCR.  They're friendly, though they may be super-busy.

h1. Troubleshooting 

* If your Kerberos username and password are good, but you can't log on to FTBFLX[NN] machines:  Have someone who CAN log into those machines heck that your kerberos principal appears in @~ftbf_user/.k5login@ in the LArIAT section.

* If you cannot ssh to FTBFLX machines: Get a kerberos ticket for yourself, then ssh ftbf_user@ftbflx01 (or whichever machine...).
