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) ...

Kevin,

The only thing that reminds me of is a line in our ldmd.conf that has been there longer than I've been here (19 years):

# Under no circumstances comment out the next allow entry to localhost
# The LDM will NOT start if the lines are commented out.

allow   ANY
    
^((localhost|loopback)|(127\.0\.0\.1\.?$)|([a-z].*\.esc\.brockport\.edu\.?$))

I'm wondering if you have a similar line in the ldmd.conf for striker, or your other ldm hosts?

Tom

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...

I am not seeing these on my server.

The other files are coming from WSI.

Hi Larry,

try
notifyme -xvl- -h striker.atmos.albany.edu -f NLDN also try the
same on your ingest machine.

There appears to be a problem. Thanks for the heads up.
Luckily not much lightning going on right now.

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.
