Hi Mark,

Just jumping in with my $0.02 worth...

A very common problem we have seen when setting up a new NOAAPort ingest
is forgetting to allow all traffic on the Ethernet interface that
the Novra S300N is connected to through the local firewall.  The iptables
entry that we use on our CentOS Linux NOAAPort ingest systems for a Novra
connected to Ethernet 'eth1' (the setting in /etc/sysconfig/iptables) is:

-A INPUT -i eth1 -j ACCEPT

Another thing that we do since we have historically used the system
logging daemon for LDM logging is disable SELINUX.  This is done with
the following setting in /etc/selinux/config:

SELINUX=disabled

NB:

- the machine will need to be rebooted after changing the SELINUX setting in
  /etc/selinux/config

- changing the SELINUX setup should not be necessary if one is using the
  non-system logging daemon logging that is available in the most recent
  LDM releases (where not using the system logging daemon is now the default)

The last thing that you will need to do if you have not already done so
is to make a couple of modifications in /etc/sysctl.conf:

#
# Enable DVBS reception
#
net.ipv4.conf.default.rp_filter = 2

#
# DVBS multicast fragment reassembly 
#
net.ipv4.ipfrag_max_dist = 0

The easiest way to make all changes active is to reboot after making them.

Cheers,

Tom
