This is because remote access to the ADDE server on your new machine
has not yet been setup.  Since this needs to be done by 'root', I
was unable to take the necessary steps when I was logged on yesterday.
Here is the high level overview of the process (specific to CentOS):

<as 'root'>

- install xinetd

  yum install xinetd

- configure xinetd to run at boot

  chkconfig xinetd on

- start xinetd

  service xinetd start

- configure xinetd to understand ADDE

  cd /home/mcidas
  sh ./mcinet2009.sh install mcadde

  This assumes that the user 'mcadde' has been created as per the
  instructions in the Unidata McIDAS-X User's Guide.  I did not check
  if this was the case on your new machine yesterday

- as 'mcidas':

  cd ~mcidas
  cp admin/mcadde_env.ksh .mcenv

  NB: Korn shell must be installed!

  Make sure that ~mcidas/.mcenv is readable by 'mcadde'!
  Review the settings in ~mcidas/.mcenv to make sure that
  they match your McIDAS installation (you can most likely
  use the .mcenv from your old machine (~mcidas/.mcenv).

- as 'mcidas'

  Configure ADDE datasets.  You may have already done this by
  copying the RESOLV.SRV file from your old machine's ~mcidas/workdata
  directory to the new machine's ~mcidas/workdata directory.

The problem is that ADDE server access has not been setup yet.

See above.

OK, good.  I should have mentioned above that inbound traffic to port 112
needs to be open on the new machine

re:

I think you mean "on your new decoder machine".  Decoders create output
that one can configure ADDE to server.

re:
> Do you have any ideas what may be blocking this?

It is not setup yet.  I would do it for you, but I (think) do not have
'root' access on your new decoder machine.

re:
> Thanks!

No worries.

Cheers,

Tom
