I _like_ someone that jump on things! >The machine name is angler.larc.nasa.gov (128.155.17.143). OK. The machine that is setup to feed you is: atm.geo.nsf.gov Your ldmd.conf file (in ~ldm/etc/ldmd.conf) should end up looking more-or-less like: --------------- snip for ldmd.conf --------------------------------- # # Programs that share a queue with rpc.ldmd # are started by it and are in the same process group. # exec "pqbinstats" exec "pqact" # # LDM5 servers we ask for data # # request <feedset> <pattern> <hostname pattern> # Request: # # bref1-4(124nm), cref, bvel1-2, & precip1 # # from: # # BYX,AMX,TBW,MLB # # Note: BREF1 <-> N0R BVEL1 <-> N0V CREF <-> NCR PRECIP1 <-> N1P # BREF2 <-> N1R BVEL2 <-> N1V # BREF3 <-> N2R # BREF4 <-> N3R request NNEXRAD "/p(N[0123C]R|N[01]V|N1P)(BYX|AMX|TBW|MLB)" atm.geo.nsf.gov ############################################################################### # Begin Access control ############################################################################### ############################################################################### # ALLOW: Who we are willing to feed # # allow <feedset> <hostname pattern> ############################################################################### # send anything to your own machine allow ANY ^((localhost|loopback)|(127\.0\.0\.1\.?$)|([a-z].*\.unidata\.ucar\.edu\.?$)) --------------- snip for ldmd.conf --------------------------------- If you were going to FILE the products, one way your pqact.conf file could look is: --------------- snip for pqact.conf --------------------------------- NNEXRAD ^SDUS[2357]. .... ([0-3][0-9])([0-2][0-9])([0-6][0-9]).*/p(...)(...) FILE -close data/nexrad/raw/\5/\4/\4_(\1:yyyy)(\1:mm)\1_\2\3 --------------- snip for pqact.conf --------------------------------- If you have never worked with the LDM before, I need to point out that the entries in pqact.conf use tabs in several places as white space. The places in the above action that use white space are: 1) between the NNEXRAD and ^SDUS 2) before FILE 3) inbetween FILE and -close All other white space in this example are spaces. After creating/modifying a pqact.conf file, ALWAYS check its validity using ldmadmin (assumes that the LDM setup is complete): ldmadmin pqactcheck If this indicates errors, you need to find and fix the errors before proceeding. Finally, if you have to modify your firewall setup, then you will need to allow atm.geo.nsf.gov AND *.unidata.ucar.edu. We want our machines to be able to contact your LDM so that we can assist in troubleshooting data problems. >Thanks again, No worries. Tom
