20040921: McIDAS in a new acct (cont.)

Hi Mynul,

OK.  This is very strange indeed.

>please login to the user  and see if you can find
>anything.

OK.  I logged on as the user and was able to run McIDAS prorams from
the command line with no problems other than /usr/openwin/bin not
being in the PATH (but this may be a minor thing).

In order to investigate why you can't see images, I need to be able to
open an X connection back to my machine here at Unidata.  I tried to
tunnel X through ssh, but this is turned off on your machine:

/etc/ssh/sshd_config:

 ...

# X11 tunneling options
X11Forwarding no

 ...

This will need to be changed to:

# X11 tunneling options
X11Forwarding yes

and then sshd will need to be stopped and restarted.

>I very much appreciate your help.

No worries.  This now has me very intrigued especially since I am able
to do routine McIDAS things like list and copy images from the user's
account:

<as the user in question>

meteor% cd ~/mcidas/data
meteor% dataloc.k LIST

So, a failure to display the image may well be something very
peculiar (as you have been saying since doing the same stuff
out of the student account works fine).

Again, I have seen nothing in the way you setup things that would
lead to the problems you are seeing!

Cheers,

Tom
