Hi Jennie,
Under Tom's advice, I removed the /home/ldma/ldm-mcidas/bin path from
batch.k, which seemed to eliminate the pqact error that was filling up
the logs. (He said that was not needed as the required software was in
the /home/mcidas/bin which was before it on the path.)
This fix caused another error to appear in mcidas.log:
/usr/local/ldm/util/batch.k: /home/mcidas/uvaworkdata/ROUTEPP.LOG:
cannot create
This was because there was already a file in that directory having that
name that was owned by ldma (although it was group writable - I don't
understand why ldm could not write to it.) It is now owned by ldm - I
changed the ownership of all the files owned by ldma in that directory
to be owned by ldm.
So, things seem to be working as far as I can tell. No problems are
appearing in ldmd.log or ldmd.log.
I'm sorry for this problem. Please let me know if you find any others.
To answer your questions: no, your upstream host does not care what user
ID you're using.
To see if your 'allow'ed at your upstream feeds and to see whether they
were getting data, I tried a notifyme to each one for which there was an
ldmd.X file in the etc directory. navier's up and getting data:
windfall: /usr/local/ldm/etc $ notifyme -vl - -h navier.meteo.psu.edu
Jan 29 23:12:39 notifyme[16646]: Starting Up: navier.meteo.psu.edu:

although it is very odd that when I do this command from your machine it
reclasses it into a request for the NEXRAD feed. When I do this command
from my machine it reclasses it to a request for ANY. Wierd.
Your "allowance" on sunset looks fine:
windfall: /usr/local/ldm/etc $ notifyme -vl - -h sunset.meteor.wisc.edu

but, I see that the conf file in your etc dir isn't named right.
Instead of ldmd.meteor.wisc.edu it should be called
ldmd.sunset.meteor.wisc.edu. I've changed that.
And, your name server can't find blueskies:
windfall: /usr/local/ldm/etc $ notifyme -vl - -h
blueskies.sprl.umich.edu
Jan 29 23:10:13 notifyme[16628]: Starting Up: blueskies.sprl.umich.edu:
20010129231013.995 TS_ENDT {{ANY, ".*"}}
Jan 29 23:10:14 notifyme[16628]: NOTIFYME(blueskies.sprl.umich.edu): 13:
gethostbyname(blueskies.sprl.umich.edu): lookup failed
I get the same from my machine. I'll have to ask if anyone knows what's
up with them.
But, it looks like your ldmfail should work now. I don't know why you
got that response from navier. Perhaps it went down just when you were
looking at things, then the failover failed because the file wasn't
named right???
Please let me know how your ldm is doing.
Anne
