Description Tux99 2011-02-28 07:48:04 CET

Description of problem:
ssh client doesn't find xauth as it looks for it in /usr/openwin/bin/xauth while xauth is in /usr/bin/xauth.
I get the following warning for example when running mgarepo co <some_pkgname>:
Warning: No xauth data; using fake authentication data for X11 forwarding.


Version-Release number of selected component (if applicable):
openssh-clients-5.6p1-4.mga1

How reproducible:
run: mgarepo co <some_pkgname>


Solution:
the solution from the Gentoo Wiki also applies to Mageia, I tested it on my Mageia alpha install and I no longer get the warning.
Add:
XAuthLocation /usr/bin/xauth

to /etc/ssh/ssh_config below the 'Host *' line.

This should really be added by default in the Mageia ssh client package.


Reproducible:

Please post your ~/.ssh/config (remove any private/sensitive data).

This is weird, today I can't reproduce this issue anymore.
If I comment out "XAuthLocation /usr/bin/xauth" in /etc/ssh/ssh_config again I don't get the warning anymore.

I haven't done any other config change apart from the XAuthLocation entry (which as I said I just commented out again to test this), so I'm not sure what caused the change of behaviour.
I do regularly apply the lasted updates, but the openssh packages don't appear to have been updated recently.

So I don't know what particular circumstance triggered the warning message, but since the config entry in /etc/ssh/ssh_config for XAuthLocation did solve the issue when it presented itself, it might still be a good idea to include it in the default /etc/ssh/ssh_config in the openssh-clients package.

I have the same issue when ssh'ing to my tablet. And the tablet doesn't even use Xorg.

About a missing XAUTH for X11R6 thou.
Don't know if that's valid in here to.
If not, I'm sorry.

This is for Mageia 1.

Hi Kristofer,

Good that you tell your issue is about Mageia 1. Even if it were exactly the same issue, when it affects a different release it should go into a seperate bug report.

When you are not sure your issue is a bug, please visit https://forums.mageia.org/en/viewforum.php?f=6 for support first.

This bug couldn't be reproduced in Cauldron, therefore I'm closing it
