[gentoo-user] ssh trouble

[gentoo-user] ssh trouble

[Allan Gottlieb]

Yesterday's update to ssh (openssh-5.1_p1-r1) is giving me trouble.

The client is allan.  The server is ajglap.

From the client (gnome-terminal) I can run ssh as follows

    gottlieb@allan ~ $ ssh ajglap
    Last login: Tue Oct 28 11:50:02 EDT 2008 from allan on ssh
    Last login: Tue Oct 28 11:54:33 2008 from allan
    xhost:  unable to open display ""
    gottlieb@ajglap ~ $ 

adding a -Y gives the same output

But I can't run other server programs from the client.  The following
used to start emacs on the server displaying a new X11 window on the
client.

    gottlieb@allan ~ $ ssh -Y ajglap emacs
    emacs: standard input is not a tty
    gottlieb@allan ~ $ 

removing the -Y gives the same output

I went to the server and created ~/.ssh/config with contents

    ForwardX11Trusted yes

But this didn't help (I also tried the risky ForwardX11).

I am planning to downgrade, but wanted to ask here first if I have just
misconfigured something (bugs.gentoo.org didn't seem to have anything
relevant).

thanks,
allan

Is "X11Forwarding yes" set in the sshd_config on ajglap?

I take it you did the obvious and restarted sshd after the upgrade?

Yes.  Indeed it was the next day that I encountered the failure.
Brian's fix was what I needed.  I must have changed the config last time
and not left my usual
# AJG:
marker to alert me.  I should have noticed the change to X11Forwarding
when I did etc-update, but unfortunately did not.

Yup, it's those pesky config files and the need to put stuff in them :-)

Config files really should be more intelligent and know to do what you want 
not what you say....

They also should be almost completely unreadable and stored in one big
conglomerated mass from everything on the system. Just like that
*other* OS!

(I can't ever seem to break out of my lurking on a serious note.)
