Hi Kwan,

Since I still see a CCNY machine (halo.sci.ccny.cuny.edu) accessing the
old IP address of adde.ucar.edu (aka motherlode.ucar.edu), I am passing
along a notification that the machine has been changed.  You are still
able to get data from adde.ucar.edu because McIDAS caches an IP address
when the user sets up pointing to an ADDE server (via a DATALOC ADD
group server).  We need to decomission the machine that was known as
adde.ucar.edu, so I am asking that you follow the instructions in the
announcement I sent to the mcidas-x and ldm-users email list a several
weeks ago:

  Users of the McIDAS ADDE server adde.ucar.edu:
  
  We have transitioned the machine known as adde.ucar.edu (aka
  motherlode.ucar.edu) from Sun Enterprise E420 to SunFire 480 hardware.
  The machine has also been moved from the NCAR machine room to the
  Unidata offices at Foothills Lab #4.
  
  Because of the relocation of adde.ucar.edu, the IP address has changed
  from 128.117.15.119 to 128.117.114.119.  This change coupled with
  McIDAS' cache of ADDE server IP addresses in its client routing table
  requires the following steps be undertaken by sites accessing data from
  the ADDE server adde.ucar.edu:
  
    <login as the user 'mcidas'>
    cd $MCDATA
    dataloc.k HOST
  
  If you have cron-initiated scripts run from an account other than 'mcidas'
  that access adde.ucar.edu:
  
    <login as the user running the cron-initiated scripts>
    cd $MCDATA
    dataloc.k HOST
  
  'DATALOC HOST' will force McIDAS to update its client routing table
  (pointed at through $MCTABLE_WRITE) cache of IP address for all hosts.
  
  Please follow the above procedures as soon as you are able.  ADDE
  access to the old adde.ucar.edu machine (IP address 128.117.15.119)
  will begin failing at the beginning of the week of November 7.
  
  Thanks in advance for your prompt attention in this matter!
  
  Please send any questions/comments regarding the above procedure to
  Unidata User Support <address@hidden>.

Cheers,

Tom
