Hi Alan,

re: can't get to waldo
>Sorry, I should have suspected that something like this might happen.
>Our campus network people have apparently tightened things up.  

This is a good thing!

>You should be able to telnet on to waldo as of tomorrow morning.

I was indeed successful in telnetting to waldo this morning, thanks.

>If you need something more, let me know.

I suggest you ask someone in your campus network group to help you out
and install ssh (Secure SHell) on your systems.  Telnet is BAD since
the user names and passwords go across the network as clear text.
All traffic when using ssh, on the other hand, is encrypted.

To get things preped, I FTPed the McIDAS-X v2002a distribution from the
Unidata FTP site to waldo, and I am building it at this very moment.  I
won't install it just yet, however.  Before doing this I need to have a
good idea of everything that you are doing on waldo and your lab
machines.  I will use the login to the lab machine that you sent
previously to snoop around before I make any major changes.

If you have any input, please send it along.  What I have in mind is
things like

o how many of each kind of satellite image you want to keep online at
  any time

o if you want to start receiving NEXRAD Level III data via the IDD (this
  is in the NNEXRAD feed)

o if you want to start receiving the NEXRAD composite images that we
  send out in the FNEXRAD IDD feed.  These products are LARGE, so
  disk space can become an issue.  To get an idea of what these
  images look like, check out the various examples on:

  US National Composites 
  http://my.unidata.ucar.edu/content/data/radar.html#composite

  The 1 km national base reflectivity composite is 14 MB after decoding
  by the ldm-mcidas decoder, pngg2gini.  A much smaller version of the
  same image, a 6 km national composite, is also sent in the FNEXRAD feed,
  so disk usage can be controlled.

o your knowledge of if anyone is still using the McIDAS-X 7.7x Fkey
  Menu

o anything else you can think of

Of course, I will send you a blow-by-blow accounting of what I do on
waldo.

Tom
