Don,

I just ran this command while pointing at adde.ucar.edu (which is now
the new version of motherlode even though it shouldn't be yet) from the
McIDAS-X v2005 installation on my home machine (FC4 Linux, 32-bit) and
got back a listing quickly:

I got back the following from papagayo:

IMGLIST RTNEXRAD/N1P ID=LIST
Image file directory listing for:RTNEXRAD/N1P
IMGLIST: No images meet the selection criteria
IMGLIST: done
IMGLIST failed, RC=2

This may be a configuration problem on papagayo; I'll check.

It might be, or it might be that both adde.ucar.edu and
papagayo.unl.edu are now running McIDAS-X v2005.  Is it possible that
you are requesting a 'compress' compressed transfer (as opposed to gzip
compressed) and it is not running correctly on those machines?
