[Dsg-hallc_controls] IP Request

[Brad Sawatzky]

I've added the SHMS names to the system:
  shms-plc-hb.jlab.org     - 129.57.165.22 
  shms-plc-q2.jlab.org     - 129.57.165.23 
  shms-plc-q3.jlab.org     - 129.57.165.24 
  shms-plc-dipole.jlab.org - 129.57.165.25 


I'm afraid you'll need to talk to Bryan Hess and/or Carl Bolitho to
get the two hms PLC names squared away on Monday.  I'm on travel
starting tomorrow and I don't think I want to change the DNS entries
for those hosts while they are still online...

Before you drop those guys a line, can you confirm the hostname to IP
mapping?  'hallc-plc2' doesn't seem to exist in DNS, but the .212 IP
you mention does map to 'hallc-plc3'.  ('hallc-plc1' seems correct.)
