Gilbert,

re: resetup the ADDE remote server on weather2

>I just did. I added the services to /etc/services, and also to 
>/etc/xinetd.d. It shoudl be working now. Can you verify?

I verified that it does work by:

1) pointing at weather2.admin.niu.edu from my machine here at the UPC
   for the RTIMAGES and RTPTSRC datasets -- worked with no problem

2) did essentially the same on weather2 as 'mcidas' -- worked with
   no problem.

re: why you are running McIDAS decoding on more than one machine

The resources I was thinking of was disk space, not CPU.  This is not a
big deal; I brought it up because you are now in the position of having
to maintain the ldm-mcidas and McIDAS-XCD decoders on two machines
as well as data scouring and ADDE serving.  This means that when
you upgrade your OS (as you seem to do a lot ;-) you need to worry
about whether things get blown out of the water, etc.

>I did set them back to weather2 and everything works fine now. That said, 
>if you think it is a burden, I will shut it off.

You have to answer if it is a burden or not.

>Now, one other thing. We're fine on McIDAS now...seems to work great. What 
>I want to do now is:
>
>1. Upgrade weather3 to Fedora 1 right after Thanksgiving
>2. Install the packages that Fedora doesn't install with an upgrade
>(that's easy; I have saved the RPMS necessary from my weather2 install)
>3. Install the THREDDS server on weather2

One part of a THREDDS server is McIDAS ADDE.  The other part is installing
a DODS server.  Since I am not involved in the DODS installation and
THREDDS catalog creation, I will need to turn you over to someone that
is intimately involved.

>Hopefully, the first and second won't take long. The third...gosh, who 
>knows?

Right.

>Anyway, those are my goals and things I want done by December 15th.

What's up with December 15?  The only reason I ask is that I have had
a series of semi-artificial deadlines since sometime this past summer.
This has resulted in the Unidata-Wisconsin datastream changes that
I wanted to do in October being pushed off until mid to late December.
Sigh...
