Robert,

I kind of knew that you were having problems getting data from Hsie,
but I had no idea that the reception was so bad.

I saw Hsie's email to support earlier and chatted with Chiz about what
might be happening.  At the time, we looked at his feed, we saw virtually
no latencies.  We will have to get a better handle on when things degrade
to see exactly what is happening.

Try pointing at ....  This is the dual 450 Mhz
machine that we have shifted all of our LDM ingest/decoding to as a stress
test (going well so far, by the way).  Let me know if you find things
that are not working correctly (I have tried the server at various times
and everything seems to work fine, but you never know...).

>Thanks,

Talk to you later...

Robert,

No problem.

This is something that we will be looking into.  It could be a problem on
Hsie's machine.

What a drag!

I agree.

Hey, no problem.  Glad to help.

>Thanks,

Later.

In the LOCAL.NAM file the redirect for the topo files
is AREA901* /home/mcidas/data.

I stick with the Sun convention of naming my home directories
/export/home, so the correct redirect is /export/home/mcidas/data.

I was thinking that ..... was the old 133Mhz Gateway, but I thought
you might have retired it.  I am going to switch to ..... now
as I missed quite a bit of the MRF last night.  The problems
with cirrus.al.noaa.gov seemed to have stopped.  I am just back
to my slow connection to them. Slow is okay as long as I stay
below max_latency.  I have not gone back to see why I missed
a lot of the MRF.

By the way, I ordered RedHat 6.0, for free (plus shipping and
handling) from Linux Systems Labs.  Thought I would give it a try.
With 5.1, cron stopped working for no apparent reason (after 3 days)
and the lp(or lpr) command stopped working.  Also after 3 days
of use, only root could connect to the X-server, I did not change
anything, this was after the computer sat there for three days.
So, I have not had good luck with it.  This is when I got rid
of it and dual booted the machine with Solaris. 

Thanks

Just wanted to let you know that I am pointing at .....
now(RTGRIDS) and it works great.
