Hi Tom-

Thanks.  If you do an nslookup on rico.joss.ucar.edu, it
gives you 69.50.67.218.  However the reverse doesn't seem to
be working.

Chris, can you look at this or should I talk to Mark?

Don,

We're trying to set up a feed from atm.geo.nsf.gov to this
machine for the RICO project.  I'm concerned that it's not
really advertising itself as rico.joss.ucar.edu, since the
error has zebra2 listed.

Any ideas on this?



I am looking through the ~ldm/logs/ldmd.log file on atm and don't see
any connection attempts by a machine called zebra2 (or zebra*).  I do
see gethostbyaddr failures for a machine with IP address 69.50.67.218
starting at about the same time as the log messages that Chris sent to
you:

Dec 03 20:51:15 atm.geo.nsf.gov rpc.ldmd[2126]: gethostbyaddr: failed for

 ...

This coupled with the output from an 'awhois' for this IP:

tells me that that DNS is not setup/setup correctly for the JOSS
machine.

You (or support) needs to work with Chris(/whoever in JOSS is the
primary contact) to get forward and reverse name service setup for this
machine.  If this turns out to not be possible for some reason, we can
circumvent the process by adding an entry in atm's /etc/hosts file to
define the hostname.  I will do this if we know that the machine with IP
address 69.50.67.218 is really the one that will be ingesting data
through the IDD during RICO.

I tried searching the archives, but the
glimpse search seems to be broken on conan.  I sent a note
to Jennifer about that.



OK.  Motherlode appears to be inaccessible this morning also (sigh)...

Hi Don,

I fired up LDM here with the "request" line you sent, and ldmd.log is
getting sets of messages like this:

RPC: Unable to receive; errno = Connection reset by peer

Is rico.joss.ucar.edu on their accept list already, or do I need to wait
for that?
My other concern is that there's an issue because the ldmd is running on a
NATted behind a firewall.  The firewall machine is rico.joss.ucar.edu, and
according to an answer from Steve Emmerson about a similar setup, it should
work as long as ldmd is claiming to be on rico.joss.ucar.edu (and it
is).  Any
ideas?

Thanks,

Chris

I should be ready to test LDM soon.  What's my upstream server, and

Use atm.geo.nsf.gov for your primary feed and emo.unidata.ucar.edu for
the backup. Both machines are set up for global allows for .edu sites.


I won't have the satellite stuff set up until monday, but for now, I
would request:

request HRS     "^H.L... KWBC (..)(..).*"  atm.geo.nsf.gov

for the gridded data.  Here is the pqact entry for gribtonc:

# GFS model on thinned grids, interpolated to global 1.25 x 1.25regular grid

HRS     ^H.L... KWBC (..)(..).*
       PIPE    decoders/gribtonc
       -q "lin,dlat=1.25,dlon=1.25" etc/1.25X1.25gfs-l.cdl
       d/RICO/GRIB/netcdf/(\1:yyyy)(\1:mm)\1\2_avn-x.nc

the cdl is attached.  If you don't have gribtonc set up, then I can do
that next week.
