Hi CJ, re: > Thank you. I'm not finding in our conf file a duplicate entry. Below is > our conf file, could you take a look at it? OK. Here are the uncommented REQUEST lines from your LDM configuration file, ~ldm/etc/ldmd.conf: ## Reorganized RSS 20110908 REQUEST WMO ".*" thelma.ucar.edu REQUEST NIMAGE "^.*.*[148]km.*" thelma.ucar.edu REQUEST CONDUIT ".*" idd.unidata.ucar.edu REQUEST NGRID ".*" idd.unidata.ucar.edu REQUEST HDS ".*" idd.unidata.ucar.edu REQUEST FNEXRAD ".*" idd.unidata.ucar.edu REQUEST FSL2 ".*" idd.unidata.ucar.edu REQUEST GPS "." suomildm1.cosmic.ucar.edu # Entries used by Brian McNolty Nexrad2 and DIFAX 20080916 REQUEST DIFAX ".*" thelma.ucar.edu REQUEST NEXRAD2 ".KMPX" thelma.ucar.edu REQUEST NEXRAD2 ".KCYS" thelma.ucar.edu REQUEST NEXRAD2 ".KAMX" thelma.ucar.edu REQUEST NEXRAD2 ".KFTG" thelma.ucar.edu REQUEST NEXRAD2 ".KGLD" thelma.ucar.edu REQUEST NEXRAD2 ".KPUX" thelma.ucar.edu REQUEST NEXRAD2 ".KGJX" thelma.ucar.edu REQUEST NEXRAD2 ".KDMX" thelma.ucar.edu REQUEST NEXRAD2 ".KARX" thelma.ucar.edu REQUEST NEXRAD2 ".KDVN" thelma.ucar.edu REQUEST NEXRAD2 ".KEAX" thelma.ucar.edu REQUEST NEXRAD2 ".KFSD" thelma.ucar.edu REQUEST NEXRAD2 ".KOAX" thelma.ucar.edu # Entries used by Paul Hein REQUEST EXP "20" socc3.caps.ou.edu The thing that is not obvious is that thelma.ucar.edu is a cname alias for idd.unidata.ucar.edu PLUS it is archaic and should be converted to use idd.unidata.ucar.edu. Also, your REQUEST for GPS data is unusual in that the extended regular expression being used is ".". This is OK, but it is more standard to match on everything which is ".*". WMO is a compound feed type whose meaning is: WMO == HDS|IDS|DDPLUS So, the duplicate REQUEST is the one for HDS to idd.unidata.ucar.edu. I strongly suggest reorganizing and consolidating your REQUESTs as follows: # Reorganized RSS 20110908 # Reorganized suggested by Unidata on 20131120 REQUEST FSL2|FNEXRAD|WMO ".*" idd.unidata.ucar.edu REQUEST NIMAGE "[148]km" idd.unidata.ucar.edu REQUEST CONDUIT ".*" idd.unidata.ucar.edu REQUEST NGRID ".*" idd.unidata.ucar.edu REQUEST GPS "." suomildm1.cosmic.ucar.edu # Entries used by Brian McNolty Nexrad2 and DIFAX 20080916 REQUEST DIFAX ".*" idd.unidata.ucar.edu REQUEST NEXRAD2 "/K(MPX|CYS|AMX|FTG|GLD|PUX|GJX|DMX|ARX|DVN|EAX|FSD|OAX)" idd.unidata.ucar.edu This will remove redundant REQUESTs, simplify the pattern for NIMAGE imagery, and cut down the total number of requests by about two thirds (22 -> 7). NB: After making any changes to the LDM configuration file, ~ldm/etc/ldmd.conf, the LDM must be stopped/started/restarted to make the changes active: <as 'ldm'> -- edit ~ldm/etc/ldmd.conf ldmadmin stop && ldmadmin start OR ldmadmin restart Cheers, Tom -- **************************************************************************** Unidata User Support UCAR Unidata Program (303) 497-8642 P.O.
