Hi Heather,

Very good.

re:

We _really_ need to get to the bottom of why this is not working!
Here are some questions:

- which Ethernet interface is the Novra connected to?

- what are the specifics of this interface?

  I am looking for the output of 'ifconfig -a'.

- have you ever used 'tcpdump' to look at the raw traffic
  for an Ethernet interface?

  For instance, if your Novra is connected to eth1, then 'root'
  could sniff the activity on eth1 using 'tcpdump':

  tcpdump -i eth1

  NB: it may be necessary to install 'tcpdump' as 'root':

  yum install tcpdump

XCD is part of the Unidata McIDAS-X distribution, but you need to build
it in addition to McIDAS-X:

cd ~mcidas/mcidas2009/src
make           <- makes McIDAS-X only

OR

make mcx       <- makes McIDAS-X only

OR

make all       <- makes McIDAS-X and McIDAS-XCD

make install.mcx
OR
make install.all

re:

Our license to distribute McIDAS allows us to bundle XCD (which _is_ a
separate package from SSEC) with our McIDAS distribution.

re:

No, it is not.

re:
> It is in /usr/local/ldm/var/logs. It gets created when I start the ldm,
> but never gets written to.

> Please advise!

The most likely reason for no log messages being written to the LDM log
file is that SELINUX is setup to be in 'enforcing' mode.  We recommend
that sites put SELINUX into 'disabled' mode, or, if the can not, in
'permissive' mode.  

Changing the SELINUX setup is done in the /etc/selinux/config file:

change:

SELINUX=enforcing

to:

SELINUX=disable

or:

SELINUX=permissive

After making this change, the easiest way to make it active is to
reboot.

After this, please make sure that the copy of ldmd.log in the
~ldm/var/logs directory is owned by 'ldm', not 'root'.

re:
> Thanks,

No worries.

Cheers,

Tom
