The 'xinetd' setup looks good.

I verified that ADDE is correctly running on omega and it is accessible
from kangaroo:

<as 'mcidas' on kangaroo>

This one step demonstrates that port 112 is open on omega (to kangaroo, at
least); that ADDE is listening for connections on port 112; and that the 
environment
needed to run McIDAS commands is in-place (existence of the file ~mcidas/.mcenv
on omega).  All excellent signs!  What doesn't work is access from outside
machines:

<as 'mcidas' on my development machine (a virtual machine running CentOS 6.2 
x86_64)>

cd $MCDATA
dataloc.k ADD RTIMAGES omega.lsc.vsc.edu
dsinfo.k IMAGE RTIMAGES

DSINFO: Cannot contact server (connect() failed)
    No Datasets found of Type: IMAGE in Group: RTIMAGES
DSINFO -- done

So, if you want your ADDE server opened to domains outside of lsc.vsc.edu,
you will have change/work with campus network folks to change a firewall
setting.

The next thing I did was to test if you have any data in the RTIMAGES dataset:

<still as 'mcidas' on kangaroo>

cd $MCDATA
imglist.k RTIMAGES/GE-IR
Image file directory listing for:RTIMAGES/GE-IR
imglist.k: No images satisfy the selection criteria
imglist.k: done


This says one of two things:

- there is no data in the RTIMAGES/GE-IR dataset

- or, the definition of the RTIMAGES/GE-IR dataset is incorrect

To investigate, I logged on omega as 'mcidas' and started poking around.

The configuration of the various datasets (descriptors) in the RTIMAGES
group is shown as:

<as 'mcidas' on omega>

These dataset definitions direct McIDAS/ADDE to look in the 
/data/ldm/gempak/images/sat
subdirectories for RTIMAGES imagery.  This directory, however, does not exist:

ls /data
ls: cannot access /data: No such file or directory

Given the ADDE configuration, it strikes me that you may have meant to create 
the following
link on omega, so I created it for you:

<as 'root' on omega>
mkdir /data
ln -s /software/ldm/data /data/ldm

After making this link, I am able to list images in the RTIMAGES/GE-IR dataset:

<as 'mcidas' on omega>

So the ADDE server is setup correctly for GRID data as well.  But, this data is
not current, so there is likely something amiss with LDM processing.

Given the last step, I took a peek at the LDM setup on omega... I do _not_ see
an action setup to decode things in to McIDAS formats.  I assume that this
is because the decoding is being done on another machine?

Wrap-up:

- it looks like all that was missing was a symbolic link to the
  ~ldm/data directory (see above).

  Please let me know if I have misinterpreted anything, and don't
  hesitate to ask questions!

Cheers,

Tom
