Hi Heather, re: > So it is warm and sunny here and we had a lot of melting. My novra stats are > back to normal: > Carrier to Noise C/N: 14.9dB > Signal Strength: -49 dBm It looks like reception should be back to normal. re: > I really thought that my server would ingest!

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 re: > I checked and the netstat looks good, and the firewall and iptables are both > disabled. > [root@npingest ~]# netstat -rn > Kernel IP routing table > Destination Gateway Genmask Flags MSS Window irtt Iface > 0.0.0.0 10.2.15.1 0.0.0.0 UG 0 0 0 eno1 > 10.2.15.0 0.0.0.0 255.255.255.0 U 0 0 0 eno1 > 10.2.15.0 10.2.15.1 255.255.255.0 UG 0 0 0 eno1 > 192.168.0.0 0.0.0.0 255.255.255.0 U 0 0 0 eno2 > 224.0.0.0 192.168.0.10 240.0.0.0 UG 0 0 0 eno2 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.
