Hi Colin,

Very good.  We needed to make sure that we could rule out the obvious :-)

Here is how to do it using 'vi':

<as 'ldm'>
vi etc/pqact.conf
-- move your insertion cursor down to the beginning of the first uncommented 
line
   for a NEXRD2 action
-- search for a space by hitting the '/' key and entering a space

This is exactly how I found out that there are (were) two spaces at the end of 
the line:

NEXRD2  ^L2-BZIP2/(KTLH)    FILE    -overwrite  -close  
/home/colin/radar/level_II/KTLH/\1.ldm

Just so you know, the spaces shouldn't have made a difference; I just wanted to 
make sure.

Very good.

Not so good...

re:

OK.  The first thing we need to do is get LDM logging working on your
system.

Questions:

- who owns the ~ldm/logs/ldmd.log file
- what OS are you using

The steps involved in getting LDM logging working are performed by 'root'.  The 
steps
are described in:

Unidata HomePage
http://www.unidata.ucar.edu

  Unidata LDM
  http://www.unidata.ucar.edu/software/ldm

    LDM 6.7.0 home page                   <- NB: the steps are the same for any 
LDM version
    http://www.unidata.ucar.edu/software/ldm/ldm-6.7.0/

      LDM Reference
      http://www.unidata.ucar.edu/software/ldm/ldm-6.7.0/basics/index.html

        LDM Preinstallation Steps
        
http://www.unidata.ucar.edu/software/ldm/ldm-6.7.0/basics/preinstallation.html

After LDM logging is working, we will be able to better see why your NEXRD2 
FILE actions
are not working.

Cheers,

Tom
