[NOAAPORT #GGP-872890]: New Noaaport server with ldm

Hi Heather,

It looks like reception should be back to normal.

Rats!

I am not sure why there are 'bad length' messages.  4032 is the correct
length.  Here, for comparison, is a bit of 'tcpdump -i eth1' output from
one of our NOAAPort ingest machines:

20:57:49.334690 IP 10.0.9.51.48987 > ietf-1-low-audio.mcast.net.eoss: UDP, 
length 4032
20:57:49.334911 IP 10.0.9.51 > ietf-1-low-audio.mcast.net: udp
20:57:49.335017 IP 10.0.9.51 > ietf-1-low-audio.mcast.net: udp
20:57:49.335150 IP 10.0.9.51.48987 > ietf-1-low-audio.mcast.net.eoss: UDP, 
length 4032
20:57:49.335290 IP 10.0.9.51 > ietf-1-low-audio.mcast.net: udp
20:57:49.335422 IP 10.0.9.51 > ietf-1-low-audio.mcast.net: udp
20:57:49.335600 IP 10.0.9.51.48987 > ietf-1-low-audio.mcast.net.eoss: UDP, 
length 4032

What is the output from the following:

<as 'root'>
ethtool -k eth1 | grep udp-fragmentation-offload

I vaguely remember (possibly dreamed) another user that was positive that
their firewall was turned off when it was, in fact, on, and that turned
out to be the cause of their ingest problem.  I am not saying that you
are incorrect in your assertion that your firewall is off, but the
firewall being on would explain not being able to ingest the UDP output
from the Novra S300N on your eno2 Ethernet interface

What is the output from:

<as 'root'>
systemctl status firewalld

re:
> I just don't know what to do next.

I'm in no better shape :-(

I am at home today.  Perhaps we could do a Google Hangout?  I
yes, I'll need to boot up my Windows laptop; please let me know.

Cheers,

Tom
