Hi Heather,
Well, the latest test that I could conceive of to get things working
on npingest failed. I am sorry to say that I am completely out of
ideas.
If I were in your position, I would reload the OS on npingest and not
try to migrate over any configurations that were in place from your
previous NOAAPort ingest instance.
The procedure I would follow is:
- load a fresh instance of CentOS
As I said in a previous email, it will be up to you if you load
CentOS 7.x or 6.10 as both _should_ work fine.
- create an 'ldm' account
Download, build and install the latest LDM release.
As you found out, you may need to load in some packages that
will be needed to build the LDM.
- after the LDM v6.13.7 is built and installed, I would first:
- configure the firewall on the newly built OS to either be
completely disabled, or to make sure that all traffic is
allowed from the Ethernet interface to which your Novra
S300N is connected
- immediately after this, I would use 'tcpdump' to see if
you see the traffic from the Novra S300N hitting the
Ethernet interface
NB: if all is well, we do not think you will see the
'bad length' indications in the 'tcpdump' output!
<as 'root'>
tcpdump -c 20 -i <ethernet interface>
If this goes well, only then would I move forward.
- setup the multicast routing
This does not have to be done before the 'tcpdump' test
since 'tcpdump' is looking at the raw device.
- setup the kernel parameters for DVBS ingest and ip
fragmentation
Do this as per our emails, not what you see before reloading
an OS!
Please let us know what you decide to do!
We will contact you if we have a brainstorm overnight!!
Cheers,
Tom
