The ~ldm/etc/ldmd.conf 'request' line syntax does not include the notion of a 'not' (i.e., everything but, etc.). Creation of a regular expression that would request the full set of GRIB messages _except_ one or more would likely be very cumbersome. If the upstream LDM is running LDM-6.4+, then you can filter the data that will be sent to the downstream pretty easily as the 'allow' feature in LDM-6.4+ explicitly includes the 'not' syntax: Please refer to the ldmd.conf webpage for details: http://www.unidata.ucar.edu/software/ldm/ldm-6.6.5/basics/ldmd.conf.html Cheers, Tom **************************************************************************** Unidata User Support UCAR Unidata Program (303) 497-8642 P.O.
