[NOAAPORT #ZLV-851048]: LDM misses data on NOAAPORT via satellite

Hi Jim,
My apologies for not being able to get back to you before now!
As far as your situation goes, I have not experienced this problem
before in any setup that I have been involved in troubleshooting.
That being said, however, I happened to notice that the configuration
listings for both of your Ethernet interfaces have the following
entry:
DEFROUTE=yes
The first exchange listed in a Google search using this as the search key
suggested that this is only used by 'networkmanager'. So the question to
you is if your systems are using 'networkmanager'?
Beyond this, I will need to get our system administrator involved to
see if he can spot anything in the listings you provided.
Cheers,
Tom
