[LDM #MFT-584849]: Errors from noaaportIngester process

Hi Carissa,

Quick note:

) was reviewing exchanges regarding the setting/resetting of values
in /etc/sysctl.conf this morning, and I got very concerned by a
reference to a Unidata web page that is not only WAY out of date,
but has misleading/incorrect information:

https://www.unidata.ucar.edu/software/noaaport/current/

As I noted in a reply to the thread that is in our inquiry tracking
system, we set two values in /etc/sysctl.conf on our Linux-based
NOAAport ingest machines:

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

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

The other thing is that our NOAAPort ingest code has been bundled with
the LDM for several years now.  The distribution available from:

ftp://ftp.unidata.ucar.edu/pub/noaaport/noaaport-1.7.1.tar.gz

is archaic and should not be used.

I will touch base with Steve and lobby for the old, out of date web
pages removal from our website, and the old distributions of our
NOAAPort ingest package removed from our FTP server.

Many apologies for the misleading/wrong information!

Cheers,

Tom
