Hi Mark,

The problem is most likely that omega does not have the 'compress' utility
installed.  The McIDAS ADDE server module mcserv tries to run compress
from the /bin, then /usr/ucb, and then /usr/bin directories.  If all
of those locations fail, the transfer will fail.

I am concerned about the core dump messages, but I won't worry about these
until you install compress on omega.  If omega is a Linux box, the standard
location for compress would be /usr/bin.  If it is an x86 box, compress
should be found in /bin, and so on.
