19991019: Can't get data after restore from backup

William,

I have verified that your connection to flip is now being made, and you
shoud see data.

[153]chiz on flip --> notifyme -v -l - -o 3600 -h mahi.mhpcc.edu
Oct 21 18:49:34 notifyme[1508265]: Starting Up: mahi.mhpcc.edu: 
19991021174934.409 TS_ENDT {{ANY,  ".*"}}
Oct 21 18:49:35 notifyme[1508265]: NOTIFYME(mahi.mhpcc.edu): OK
Oct 21 18:49:35 notifyme[1508265]:    25688 19991021175013.949    NMC2 075  
/u/ftp/gateway/ncepe/nggrib/ruc2a.991021/ruc2.T17Z.bgrbanl 
!grib/fsl/105/#236/199910211700/F000/HGT/hybrid lev 36! 000075


The denying connection message for notifyme to your own computer
can be resolved in 1 of two ways:

1) try "notifyme -v -l - -o 3600"
   By default, this will connect to "localhost" which should be "allowed"
   access in the ldmd.conf file. Eg, our distribution ldmd.conf file
   has the lines:
# send anything to your own machine
allow   ANY
    ^((localhost|loopback)|(127\.0\.0\.1\.?$)|([a-z].*\.unidata\.ucar\.edu\.?$))

this allows localhost and flip here at unidata to connect to your machine.
By allowing flip, I can run notifyme to verify that you are getting data.

2) add an allow line for mahi.mhpcc.edu to the ldmd.conf. When you
specify -h "hostname", then gethostbyname requires that the name match
in the ldmd.conf file. Eg, add an additional allow line:

allow ANY mahi\.mhpcc\.edu$


One more additional note....since the fire at NCEP, the RUC grids are being
created by FSL, so you will notice in the product header that the
id following the ! character has "!grib/fsl/105" instead of "!grib/ncep/86"
