Hi Alan,

OK, then this is the problem.

McIDAS will create a zero length file when it tries to open
one that does not exist.  This tells me that the file pointed
to by the REDIRECTion either did not exist when the user
tried to start a session, or it had been deleted.

OK.

A valid (non-empty) SYSKEY.TAB file should be copied from the
distribution to the directory pointed to by your REDIRECTion.  The copy
of SYSKEY.TAB delivered with the distribution can be found in
/home/mcidas/data.  As 'mcidas' copy it over to the REDIRECT directory
and make sure that its read write permissions are 664 (owner and group
read/write, and world read).

There is a step in the installation that has you copy SYSKEY.TAB
and ROUTE.SYS to the directory in which ldm-mcidas and McIDAS-XCD
decoders create their output.  Since SYSKEY.TAB did not exist
in the directory named in the REDIRECTion in the LOCAL.NAM file,
it is possible that ROUTE.SYS did/does not either.  If this is the
case, also copy ROUTE.SYS to that directory.  The copy of ROUTE.SYS
in the distribution can be found in /home/mcidas/workdata.  The
copy needs to also have 664 permissions (copy it as 'mcidas'
also).

Nonetheless, ROUTE.SYS and SYSKEY.TAB need to be "findable".

Right.

OK.  I am in DC right now, so when I can get to this is in
question.

Talk to you later...

No worries.
