[Datastream #IZJ-689237]: Additional Datafeeds

Hi Jeff,

re: running GEMPAK decoders from the command line
> That looks like a pain in the butt, so I'll just wait...

It is not that hard...

re: strange problem seen on another user's machine that was fixed by disabling
IPv6

Yes, but HDS is part of compound feed types:

WMO     == HDS|IDS|DDPLUS
UNIDATA == WMO|UNIWISC

Yes, but it does mention UNIDATA which is the union of HDS|IDS|DDPLUS and 
UNIWISC.

Yes, I was just talking to Michael James (our GEMPAK guy) about the 'can't read 
file'
messages.

re: changing the system clock setup
> OK.  I might try that.

After talking with Michael, I am leaning towards you first trying to use a 
pre-built,
32-bit version of the decoders that are currently giving you problems.  To test 
this
out, I am downloading the 32-bit distribution to the 
/home/gempak/GEMPAK5.11.1_32
directory I just created on whistler.

re: what kind of access to you have

Thanks.  Like I said, things are a bit fuzzy (too many different sites problems
floating through my head).

*** some time later ***

I tried running 32-bit versions of dcmetr, dcacft, dcmsfc, and dcgrib2 on 
whistler,
but had no luck.  One of the problems was that the shared gfortran library 
needed
is not available.  I copied over one from the system on which we built the 
GEMPAK
5.11.1 32-bit binary release, and set LD_LIBRARY_PATH for user 'ldm', but this
did not result in working versions run by pqact.  Quite frankly, I do NOT 
understand
this!

On a hunch, I decided to replay the experiments I ran with my other user last 
Friday:

<as 'ldm'>
notifyme -vl-          <- ran in one login window
pqcat -vl- > /dev/null <- run in another login window
ldmadmin watch         <- ran in another login window

The listings were different!  The 'ldmadmin watch' invocation showed the 
receipt of NEXRAD3
products, but the 'notifyme -vl-' and 'pqcat -vl- -o 600 > /dev/null' 
invocations did not.
This disparity in the listings exactly matches what we saw on the other user's 
machine last
Friday!

Because of this strangeness, I think that the first thing to do is to turn off 
IPv6 support.
I would do this for you if I had 'root' access, but since I don't, please 
perform the
steps listed in:

http://blog.taragana.com/index.php/archive/how-to-disable-ipv6-on-fedora-linux-why/

Please note that you _will_ need to do a system reboot after all steps have 
been made
(the URL says that you might have to reboot).

Cheers,

Tom
