Jim,

???

I need to see the full contents of the .cshrc to really understand
this comment.

The ADDE remote user 'mcadde' should have /bin/false as its shell.  The
reason for this is that one should _not_ be able to login as this
user.  A regular user can specify whatever shell s/he wants (C, Bourne,
Korn, tcshc, bash, etc.).

I have _got_ to see this.

MCPATH is incorrect.  The first MCPATH directory must be the user's
MCDATA directory.  The MCPATH for the user 'frysingj' should look
like:

setenv MCDATA /export/home/frysingj/mcidas/data
setenv MCPATH ${MCDATA}:/export/home/mcidas/data:/export/home/mcidas/help

Note colons instead of semi-colons and the lack of quotes.  I am not sure
what will happen to McIDAS with this kind of MCPATH specification.

>   setenv MCTABLE_WRITE /export/home/frysingj/mcidas/data/MCTABLE.TXT

These look OK.

I am sure that this is caused by the bad MCPATH specification.  The main
reason is that the first directory in MCPATH must be one that the user
can write to.  Your MCPATH has the /export/home/mcidas/data directory
as its first, and you (any user other than 'mcidas', 'mcadde', and 'ldm')
should _not_ be allowed write permission in this directory.  Given this,
files that should get created for the McIDAS session are not created
and all hell breaks loose as you see.

This sounds like your X session is running in 8-bit mode and you are
out of colors (are things like Netscape running, etc. ?)

Again caused by the bad MCPATH.

OK.  I will take a look tomorrow.

Since you are sturggling at this point, is there any possibility that
I could get the login as you (frysingj) and 'ldm' so I could fix
the things that are slightly out of wack?  This would get you back
on track quickly and better prepare you for confiuring general user
accounts for McIDAS.

The key comment in a previous email I sent was to start McIDAS as:

mcidas config

the first time and to make sure to specify the automatic startup of
MCGUI and to save defaults in the defaults file (which is ~/.mcidasrc).
When .mcidasrc does not exist, this will create it.

It is read each time McIDAS starts if it exists.  If it doesn't exist,
defaults are applied for each configurable option.

Again, logins as you and the LDM user would allow me to do a couple
of things that would get you past the current roadblock.
