Xiaodong,

Anne will be out of the office until sometime next week (or the week
after).  Perhaps I can help out.  If the login information to halo
has not changed, I will try to get on.  I just logged in and became 'ldm', 
and am taking a look.  The persistent error I see in the LDM log file,
~ldm/logs/ldmd.log, is:

Aug 20 22:12:15 halo.sci.ccny.cuny.edu redwood[28760]: 
FEEDME(redwood.atmos.albany.edu): can't contact portmapper: RPC: Timed out

A 'notifyme' invocation from halo to redwood shows the same problem, so
the inability to contact the portmapper appears to be the cause of your
problem.

halo.sci.ccny.cuny.edu{ldm}% notifyme -vxl- -h redwood.atmos.albany.edu
Aug 21 14:37:48 notifyme[29831]: Starting Up: redwood.atmos.albany.edu: 
20010821143748.938 TS_ENDT {{ANY,  ".*"}}
Aug 21 14:38:23 notifyme[29831]: NOTIFYME(redwood.atmos.albany.edu): can't 
contact portmapper: RPC: Timed out
        NOTIFYME(redwood.atmos.albany.edu): can't contact portmapper: RPC: 
Timed out
        NOTIFYME(redwood.atmos.albany.edu): can't contact portmapper: RPC: 
Timed out

I will have to investigate this further and get back to you.

The procedure is the following:

o notify your upstream feed site(s) of the impending change.  You will
  need to give them your current machine name/IP address and the name
  and IP address of the machine you will be moving your LDM to

o CC Unidata Support on your interactions with your upstream feed site(s)
  so we can keep abrest of your progress and update our online information

To find out who to contact at your upstream feed site(s), please review
the site contact list in:

http://www.unidata.ucar.edu/projects/idd/sitelist.html
