Hi Chris,
Well, here's the trail of what I did and my conclusions at each point:
First, I did 'ldmadmin watch' to see what's coming in and how timely it
is. Right away I can see there's a problem:
[ldm@thermal ~]$ ldmadmin watch
(Type ^D or ^C when finished)

If you take the difference between the current time, field 3, and the
ingest time, field 6, you'll see that you are receiving products that
over an hour old. By default, these products will be rejected by your
ldm. To confirm this, I took a look in your logs. Here's what I found:

The 'skipped' lines mean that your ldm rejected those products. They
also show that each product was just 60 seconds over the time limit,
which is one hour, be default. Looks like this has been going on for a
while.
I decided to check your system clock to make sure it was running on
time. I compared it with my own. Mine is synchronized via NNTP, so
it's pretty accurate. Here's what I got:
[ldm@thermal ~/logs]$ date -u
Tue Oct 2 21:56:40 UTC 2001
(anne) imogene:/home/anne/conferences/AMS 59 % date -u
Tue Oct 2 21:53:34 UTC 2001
So your clock is ahead by three minutes. Generally that wouldn't be a
big deal, but it looks like you're running on the edge, with products
being rejected for being 60+ seconds late. Resetting your clock would
help.
My next question is to figure out why there's such a delay. From your
ldmd.conf I see that your primary upstream feed is pluto.met.fsu.edu.
I'd like to know if they're getting products on time. So, I did a
notifyme to them from your machine:
[ldm@thermal ~/etc]$ notifyme -vl - -h pluto.met.fsu.edu
Oct 02 22:08:39 notifyme[3037]: Starting Up: pluto.met.fsu.edu:
20011002220839.111 TS_ENDT {{ANY, ".*"}}
Oct 02 22:08:39 notifyme[3037]: NOTIFYME(pluto.met.fsu.edu): reclass:
20011002220839.111 TS_ENDT {{FSL2|UNIDATA, ".*"}}
Oct 02 22:08:40 notifyme[3037]: NOTIFYME(pluto.met.fsu.edu): OK
...
And then I waited a long time. For comparison, I did a notifyme to them
from my own machine:
(anne) imogene:/home/anne/conferences/AMS 60 % notifyme -vl - -h
pluto.met.fsu.edu

From the time differences I can see that FSU is only about two minutes
off with the IDS|DDPLUS feed.
And, I'm *still* waiting for more to come from the 'notifyme' that I did
from your machine.
This indicates network trouble between your site and FSU. Now, I'll
kill the notifyme and instead do a traceroute to FSU to see the times
that it reports:

This traceroute never completed - I killed it because it took way too
long. These results are not good. Asterisks indicate either a time out
or a firewall. In your case, you can't even get a decent time getting
off your own campus. Here's a traceroute to FSU from my own machine for
comparison:

The times greater than 80ms are not that good. But, regardless, we saw
that FSU was getting products in a relatively timely manner.
Now, I'll do a traceroute to your machine from my own. This would
reflect the path that a product would take from our server, motherlode,
to your machine. (Maybe most of your products come from some other top
tier machine, but this is still a significant piece of data):

I killed this one too. These last times are B-A-D BAD. My next query
is to identify the site where things go to pot. (I had to do this from
a different machine that had the 'awhois' command that I wanted to run):
(anne) laraine:/export/dist/ftp/pub/idd/ldmstats 53 % awhois
208.46.254.134

To single out one record, look it up with "!xxx", where xxx is the
handle, shown in parenthesis following the name, which comes first.
The ARIN Registration Services Host contains ONLY Internet
Network Information: Networks, ASN's, and related POC's.
Please use the whois server at rs.internic.net for DOMAIN related
Information and whois.nic.mil for NIPRNET Information.
AHA! It's a Qwest site!
I'm not sure what this means. It could be due to high traffic. It
could be a hardware problem. But, this connection problem is a
significant one. Before I spend the time to look at other pieces of
your configuration, it's important to address this issue. Were you
having connectivity problems before?
First, do reset your clock. If you can get an NTP daemon running, that
would be best. If you want info on how to do that, let me know. But,
in the meantime you can simply reset the clock via 'date' or some other
simple tool.
Next, you must talk with your network engineers and describe the problem
to them. Take them some traceroutes to show them the problem. Maybe
you can get some info about the path (or paths) to FSU. If you'd like
more data points from me, let me know.
There is one other thing you can do. In your '~ldm/bin/ldmadmin'
script, you can change the default setting so that your LDM won't reject
products that are just over an hour late. For example, you might want
to accept products that are two hours old. I can make that change for
you if you want - I'll mark it in the file so you can see what I did.
Let me know how you would like to proceed from here.
