Matt, I think I fixed the problem. I tested the fix pqsend(1)-ing to a new version of the LDM server and it worked just fine. Install the release-candidate ftp://ftp.unidata.ucar.edu/pub/ldm/ldm-6.4.2.4.tar.Z on the University of Wisconsin servers and try it. And, please, keep us apprised. Tom, you shouldn't have to do anything unless you're planning on receiving data-products via pqsend(1) or ldmsend(1). Once the new version is installed on the UW servers, your stuff should just start going through. Regards, Steve Emmerson
