Re: X11 forwarding
I've had some to time to go back and make this work properly through X11
forwarding. I've followed the Ported Tools guide to setup X11 forwarding,
which included compling the xauth program and changing some parameters in
the sshd_config. But when I connect via PuTTY with X11 forwarding turned
on I receive these messages. Each time I see it creating a new .Xauthority
file, yet I never see that file being created. Also I receive some errors
about bad display names. And lastly I receive erros trying to run the X
application. No amount of googleing has had an answer to the bad display
name, which I assume also has something to do with the errors running the
app. Anyone with experience with X11 on z/OS have an idea what I am doing
wrong?

Your initial stated objective was to get X11 forwarding working and

But now that it isn't but something else is working, you seem satisfied.

Well, what is working is _not_ tunneling X over SSH. You're sending X
traffic back to your desktop over an entirely different port, with no
encryption. If anyone decides to close off traffic on ports 6000+
you're
going to be out of luck.
A common pitfall is that programmers accustomed to other techniques code
in their .profile, $ENV, .login, .cshrc, .bashrc, ... code to set and
export
DISPLAY, often based on parsing the output of a command such as who am
i.
This code must be made conditional wherever it occurs (often in several
places) with a conditional construct such as:
DISPLAY=${DISPLAY-`find-value-of-display`} export DISPLAY
in order not to override the value correctly set by sshd.

Re: X11 forwarding
Check x11DisplayOffset value. If should be set to something like 10 if you want to forward directly via port 6010, or set to 0 if you want to tunnel through your SSH port 22 connection. My DISPLAY is set to 127.0.0.1:0 and my x11DisplayOffset is 0. -- Donald J. dona...@4email.net On Wed, Jun 26, 2013, at 10:09 AM, Mark Pace wrote: I've had some to time to go back and make this work properly through X11 forwarding.

I think there's a make macro that lets you control the shell make uses, but the default really, really should be POSIX shell, not the caller's login shell. Are you using IBM's make? I've had similar problems because when IBM's make thinks it can parse the command it uses spawn() rather than system(). Sometimes it guesses wrong. For that matter, what does system() use nowadays? long ago it used to use the user's login shell, which is wrong, rather than POSIX shell. -- gil -- For IBM-MAIN subscribe / signoff / archive access instructions, send email to lists...@listserv.ua.edu with the message: INFO IBM-MAIN

Your initial stated objective was to get X11 forwarding working and verified.
But now that it isn't but something else is working, you seem satisfied.

A common pitfall is that programmers accustomed to other techniques code
in their .profile, $ENV, .login, .cshrc, .bashrc, ... code to set and export
DISPLAY, often based on parsing the output of a command such as who am i.
This code must be made conditional wherever it occurs (often in several
places) with a conditional construct such as:
DISPLAY=${DISPLAY-`find-value-of-display`} export DISPLAY
in order not to override the value correctly set by sshd.
