[ldm-users] 20151202: 20151202: NLDN feed back up, but moved - was Re: NLDN feed down (cont.)

requesting lightning from striker.

OK, thanks for the info.

All: I think I see the problem in an ALLOW line in the ldmd.conf file
on striker.  I have let Kevin and David know about the problem so
they can implement the needed change when they get a chance.  I would
make the change myself, but someone is editing the file right now...

Thanks to everyone for your patience!

Cheers,

Tom

Questions for everyone:

- what are your ldmd.conf REQUEST line(s) for LIGHTNING data?

Tom,

I just have 1 line (in other words, I don't get USPLN):

request    NLDN    ".*"    striker.atmos.albany.edu

- what IP address does striker.atmos.albany.edu resolve to on
 your LDM machines?

 The correct name <-> IP mapping is:

 stiker.atmos.albany.edu <-> 169.226.16.37

[393] vortex% nslookup striker.atmos.albany.edu
Server:  adrisc1.admc.brockport.edu
Address:  137.21.1.15

Non-authoritative answer:
Name:    striker.atmos.albany.edu
Address:  169.226.16.37

[394] vortex% nslookup 169.226.16.37
Server:  adrisc1.admc.brockport.edu
Address:  137.21.1.15

Name:    striker.atmos.albany.edu
Address:  169.226.16.37

will troubleshoot things on striker.  If you are only REQUESTing the
NLDN feed, also let us know so we can troubleshoot.

I only request NLDN, and I'm not getting any data.

Here is a nice explanation of the difference between flashes and stokes:

http://hyperphysics.phy-astr.gsu.edu/hbase/electric/lightning2.html

"Lightning flashes and strokes

The term lightning flash is used to describe the entire discharge,
which takes on the order of 0.2 seconds. But a flash is usually made up
of several shorter discharges which last less than a millisecond and
which repeat rapidly enough that the eye cannot resolve the multiple
events. These individual discharges are called strokes. Sometimes the
strokes are separated enough in time for the eye to resolve them, and
the lightning appears to flicker."

Cheers,

Tom

Something about how your allow is configured maybe? Maybe something
hard-wired in the ldm on striker that Tom put in when getting this
up and running? Or something in the hosts file messing with DNS
resolution?

My request to you looks like this:

REQUEST         NLDN    ".*"    striker.atmos.albany.edu

[should probably change that from NLDN to LIGHTNING if that's the
convention now, but doesn't seem to be the issue..]

Thanks all for the reports.

Looking at our ldmd.log, I notice that for each client that is
connecting, we see lines like this:

Dec  2 17:31:38 striker <snip>.edu(f[11638] NOTE: topo: <snip>.edu
{{LIGHTNING, (^((localhost|loopback)|(127\.0\.0\.1\.?$)))}}

Perhaps some LDM experts can comment, but the last part (i.e. the
part with "localhost, loopback, 127.0.0.1") doesn't seem right.  At
least we don't see similar entries on our LDM logs on
cascade.atmos.albany.edu (which requests/feeds the vast majority of
our non-NLDN products) ...

I am also seeing the same thing.   I do a "kill -USR2" on the ldmd
process
connected to striker, and it never logs anything.   But running
notifyme on the
same machine lists products from striker.

but a similar notifyme from another aos.wisc.edu machine to
idd.aos.wisc.edu shows nothing.

ldmadmin watch -f lightning on idd.aos.wisc.edu similarly shows no
products coming through. Strange..

Curious, we see the same thing when we REQUEST from striker from
one of our LDM client machines.  We connect ok, but on the client
machine we see no products coming through.

Is anyone receiving NLDN products from striker.atmos.albany.edu?
Tom Y, how about you?

Larry, David,

I'm having the same problem... WSI stuff is coming through via
request lines, but NLDN is not.  But notifyme pulls NLDN through
okay.  I've tried several variations on the request line thinking
it's getting confused with the WSI request line, but so far no
luck.  I don't think I had this problem before...

Hi all,

Thanks to the help of Tom Yoksas, and other Unidata staff, we
now have the NLDN feed available again. We also moved it to
a new computer.
Please change your request from
       striker2.atmos.albany.edu to
       striker.atmos.albany.edu

(note, the “2” has been removed from hostname)
I am not seeing any products coming through.

Products are now being sent out in 1 minute bins (instead of 6
minute) so the data will be a little more timely.

We also have the possibility of including both cloud to ground
and cloud to cloud data. Currently the feed contains only cloud
to ground strikes. Is this something you’d be interested in?
Would it break what you are doing now?
Both the one minute files and cloud to cloud would be great
for us.
We forward lighting products to our research aircraft to
partially mitigate hazards of operating around convection.

Hi all,
      The NLDN lightning feed from striker2 is currently not
working properly. It is sending out products, but since about
16Z 12 November those products have not contained any useful
data. It is a slow time of year, but there has been
lightning since Nov 12.
       We are working toward finding a solution to this
problem.
In the mean time, you might want to use the USPLN/NAPLN/GLN
data feed.
Thanks for your patience as we work to get NLDN going again.
