Tom,

OK.  The symptoms you reported led me to believe that the REDIRECTions
needed to locate data files had not been set.

This makes sense.  McIDAS REDIRECTions are inherited by XCD decoders by
virtue of being run by startxcd.k which, in turn, is run from the
Bourne shell script xcd_run which, in turn, is run during LDM startup.

Super.  Now all that is needed is a little cleanup in the 'mcidas'
working directory.

The WARNING message is telling us that the 'kill -HUP' to the inetd
process is failing.  The process for setting up the remote ADDE
server is:

o mcinet7.6.sh modifies /etc/services and /etc/inetd.conf
o a HUP is sent to the inetd process telling it to reread its configuration
  file, /etc/inetd.conf

Hmm... can you as 'root' send a HUP to inted successfully?

This should work on Solaris 2.5.x.

The number of images that are kept is governed by the existance of the
McIDAS file ROUTE.SYS in the directory in which the AREA files will be
created.  If ROUTE.SYS does not exist there, or if it is not readable
and writable by the user running the LDM, then the number of images
that are kept is fixed (4 for all products except the MDR radar images
and 6 for the MDR images).  A copy of ROUTE.SYS that is configured to
keep 10 of each kind of image in the Unidata-Wisconsin datastream is
included in the McIDAS-X 7.6 distribution.  It will be installed in the
~mcidas/workdata directory.  In addition, a copy of SYSKEY.TAB can be
found in the ~mcidas/data directory.  Both of these files should be
copied to the directory where AREA files will be made.  This is the
/data/mcidasd directory on your system.  After you copy these you
should make sure that they both have group read/write permissions.
This should be sufficient IF you put the users 'mcidas' and 'ldm' in
the same group.

>Thanks for your help.

You are welcome.
