Hi Russ,
Thanks for sending us the output of the various commands we asked for
yesterday. For the most part, I didn't see anything that looked out
of place EXCEPT the following:
> [rlancast@fos2-cip ~]$ netstat -gn
> IPv6/IPv4 Group Memberships
> Interface RefCnt Group
> --------------- ------ ---------------------
> lo 1 224.0.0.1

> ens32 1 224.0.1.6
> ens32 1 224.0.1.10
> ens32 1 224.0.1.9

Notice that the multicast addresses 224.0.1.1 - 224.0.1.10 are not all
associated with the same interface:
> ens32 1 224.0.1.5
> ens32 1 224.0.1.6
> ens32 1 224.0.1.7
> ens32 1 224.0.1.8
> ens32 1 224.0.1.9
> ens32 1 224.0.1.10
> ens34 1 224.0.1.1
> ens34 1 224.0.1.2
> ens34 1 224.0.1.3
> ens34 1 224.0.1.4
All ten of the multicast addresses should be associated with the
Ethernet interface to which your Novra S300N is connected, ens34.
As an example of this, here is the 'netstat -gn' output from one
of our CentOS 6 NOAAPort ingest machines:
~: netstat -gn

eth1 1 224.0.1.7
eth1 1 224.0.1.1
eth1 1 224.0.1.4

eth1 1 224.0.1.6

eth1 1 224.0.0.1
eth0 1 224.0.0.1
lo 1 ff02::1
eth1 1 ff02::1
eth0 1 ff02::1
It is very interesting (to me, at least) that the IP addresses that
we _added_ to your LDM configuration file are all associated with
ens32, not ens34. Because of this anomaly, I need to see your
the contents of your ~ldm/etc/ldmd.conf file. If possible, please
send the file as an attachment, not as a cut and paste from a
listing.
The other things that I would like to see are your:
/etc/hosts
/etc/sysconfig/network-scripts/ifcfg-ens32
/etc/sysconfig/network-scripts/ifcfg-ens34
On a new note, please send us the output of:
netstat -nl
The output of 'netstat -nl' run on our same CentOS 6.8 NOAAPort ingest
machine looks like:
~: netstat -nl

Notice how all multicast IP addresses 224.0.1.1 - 224.0.1.10, inclusive, all
have the Foreign Address 0.0.0.0:*. I am guessing that your listing may look
different.
re:

OK. I asked for this to verify where the HOME directory of 'ldm' is.

I asked for the output of 'cat /etc/fstab' and 'mount' so that we could see if
the 'nosuid' flag was set for the directory (/home/ldm) where your LDM is
installed. As you can see, it is not.
Cheers,
Tom
