First of all LDM is toally new to me. I am try to set this up for a
friend.
I have a new LDM 6.13.12.42 installation.
I used the latest from github - https://github.com/Unidata/LDM.git.
I used:
./configure --with-noaaport --with-ingester --with-retrans
--with-gribinsert
to configure. I am in a Centos 7 server.
The main goal of this system is to receive data from a noaaport
reciver / modem.
The system reports:
cmcs -list
S300 IP address: 192.168.1.2 MAC: 00-06-76-05-02-4d
so I 1) know that the server sees the modem and 2) it is a Novra type
modem:
http://www.satcomsource.com/Novra-S300-Technical-User-Manual.pdf
Currently we have an OLD Centos 5 system with propriatary noaaport
software that works with that modem. The Centos 5 system is having
some issues so we're looking to move the noaaport receive process to
a newer system.
The modem is on a 192.168.1.x network that is just setup for the
modem and the servers receiving data from it.
According to:
https://www.unidata.ucar.edu/software/ldm/ldm-current/utilities/noaaport/index.html
I need to setup:
sysctl -w net.ipv4.ipfrag_max_dist=4096
sysctl -w net.ipv4.conf.default.rp_filter=2
sysctl -p
which I have done. I have disabled selinux and he firewall on the
Centos 7 box. I have verified that the
/proc/sys/net/ipv4/conf/default/rp_filter
and
/proc/sys/net/ipv4/ipfrag_max_dist
are the expected values after the system has booted.
If I run
tcpdump -n -i enp7s0f1 | grep 192.168.1.
tcpdump: verbose output suppressed, use -v or -vv for full protocol
decode

I see data from the S300 modem... I assume that is the Multcast Data
that the modem sends.. but that is guess on my part.
I have tried server different instances ( different values ) for:
EXEC "noaaportIngester -x -m 224.0.1.1 -I 192.168.1.99 -l
/home/ldm/var/logs/ldmd.log"
EXEC "noaaportIngester -x -m 224.0.1.2 -I 192.168.1.99 -l
/home/ldm/var/logs/ldmd.log"
EXEC "noaaportIngester -x -m 224.0.1.3 -I 192.168.1.99 -l
/home/ldm/var/logs/ldmd.log"
EXEC "noaaportIngester -x -m 224.0.1.4 -I 192.168.1.99 -l
/home/ldm/var/logs/ldmd.log"
or
EXEC "noaaportIngester -x -m 224.0.1.1 -l /home/ldm/var/logs/ldmd.log"
EXEC "noaaportIngester -x -m 224.0.1.2 -l /home/ldm/var/logs/ldmd.log"
EXEC "noaaportIngester -x -m 224.0.1.3 -l /home/ldm/var/logs/ldmd.log"
EXEC "noaaportIngester -x -m 224.0.1.4 -l /home/ldm/var/logs/ldmd.log"
but when I do ldmadmin start or ldmadin restart the logs show:

so .. what am I missing in order to received data from this S300
noaaport receiver?
On the OLD / WORKING system we have:
[PARAMS]
NOAAPORT_BUF_SIZE = 1,1,1,1
LOGMASK = 0x06,5
NUM_USERS = 4
NUM_SATCOMM_BOARDS = 1
SAVE_HDLC_FRAMES = {1,0}, {2,0}, {3,0}, {4,0}
NOAAPORT_DATA_STREAM = DVB_NWSTG,DVB_GOES,DVB_NWSTG2,DVB_OCONUS
MULTICAST_INTERFACE = 192.168.1.4
On the new LDM system... I didn't configure: MULTICAST_INTERFACE =
192.168.1.99 ( the new box is 192.168.1.99 ) anyplace.
any one have any ideas on why the LDM noaaportIngester stuff doesn't
appear to be ingesting?
