Ric and Scott,

After Ric's note on July 23:

I assumed that the University of Puerto Rico would start getting the
MCIDAS imagery that they were requesting.  I just received the following
from Karli Lopez of UPR:

  Tom,
    After you sent an email to sirocco.srcc.lsu.edu in order to fix the
  problem, I received a copy of their reply but there had been no
  immedeate effect on the stream as of Friday.  I intended to wait a day
  to see if the feeds were reestablished.  However I didn't get access to
  the machine until today and have found that the streams are still not up
  and we are getting the same 'Access Denied by remote server' error in
  out ldmd.log file (july 28th). Please help us correct this problem.
  
  Thank you,
  
  Karli Lopez

Scott,

The 'Access Denied by remote server' indicates to me that UAH is not
allowing the feed request from UPR.  Could you check into this
and verify that you are requesting MCIDAS data from LSU?

Thanks.

Ric,

I decided to do a quick check to see if you (LSU) are getting the MCIDAS
products:

(zero:ldm) 47 % notifyme -vxl- -f MCIDAS -o 3600 -h sirocco.srcc.lsu.edu
Jul 28 18:04:53 notifyme[28877]: Starting Up: sirocco.srcc.lsu.edu: 
19990728170453.690 TS_ENDT {{MCIDAS,  ".*"}}
        NOTIFYME(sirocco.srcc.lsu.edu) returns OK
Jul 28 18:04:53 notifyme[28877]: NOTIFYME(sirocco.srcc.lsu.edu): OK
Jul 28 18:10:39 notifyme[28877]: Timed out after 300 seconds inactivity
Jul 28 18:10:39 notifyme[28877]: Disconnect
        NOTIFYME(sirocco.srcc.lsu.edu) returns OK
Jul 28 18:11:04 notifyme[28877]: NOTIFYME(sirocco.srcc.lsu.edu): OK

and it appears that you are not.  Could you check things on your end
in two ways:

o make sure that you are requesting and getting MCIDAS data
o verify that UAH is requesting and being granted access to MCIDAS data

Thanks.

Scott and Ric,

Would you please CC Karli on your replies to this email?  Thanks to both...

Tom Yoksas

Folks,

Again, my sincere apologies for the neglect. I am really swamped
trying to get my polar antenna recalibrated...oof...OK, enough
complaining...

My logs are full of messages like:

Jul 28 19:59:22 sirocco unidata[1307]: run_requester: 19990728185915.390 
TS_ENDT {{MCIDAS, ".*"}} 
Jul 28 20:00:23 sirocco unidata[1307]: FEEDME(unidata.ssec.wisc.edu): 
13: gethostbyname(unidata.ssec.wisc.edu): lookup Timed out

But, ldmping and nslookup and traceroute all found it find...So, I
restarted the LDM feed on sirocco and ran "ldmadmin watch" and
immediately noted a couple of MCIDAS products coming in. As I write
this, I am still getting them.

ldmd.conf contains:

        ...

        request MCIDAS ".*"  unidata.ssec.wisc.edu 
        ... 

        allow UNIDATA   aqua.atmos.uah.edu

Following the restart, the log shows:


Jul 28 20:36:27 sirocco unidata[6921]: run_requester: Starting Up: 
unidata.ssec.wisc.edu 
...
Jul 28 20:36:28 sirocco unidata[6921]: run_requester: 19990728203526.240 
TS_ENDT {{MCIDAS, ".*"}} 
...
Jul 28 20:36:29 sirocco unidata[6921]: FEEDME(unidata.ssec.wisc.edu): OK


The request from aqua that follows a restart looks like:

Jul 28 20:36:36 sirocco aqua[6930]: Connection from aqua.atmos.uah.edu
Jul 28 20:36:36 sirocco aqua(feed)[6930]: Starting Up: 19990728194014.217 
TS_ENDT {{UNIDATA, ".*"}} 
Jul 28 20:36:36 sirocco aqua(feed)[6930]: topo:  aqua.atmos.uah.edu UNIDATA
Jul 28 20:40:57 sirocco aqua(feed)[6930]: h_clnt_call: aqua.atmos.uah.edu: 1: 
time elapsed
24.528749


Should this be MCIDAS instead of UNIDATA on each end?

We have had some off-campus network problems, so maybe the connection
fails and doesn't restart properly...There's actually good/bad news
here too. In the next few days we will take sirocco down briefly to
reconfigure its IP address in conjunction with it's migration over to
a complete rewiring of the building to a 100baseT backbone on the
vBNS! 

Just checked my stats file and see:

19990728210615  MCIDAS  unidata.ssec.wisc.edu   1       56903   4.54    5@0615  
19990728210619

so, it looks like, for the moment, you should be able to get the
MCIDAS from sirocco, but it's possible I'm missing something. Any
thoughts?
